    Your lessons are truly so wonderful. After many years of trying to figure what business I want to start and what career would include all of my passions I finally have decided to start my own Private Cosmetics Label.- I am however NOT A CHEMIST by any means. Never would I think of myself as a true chemist- but as a business owner I think it’s valuable knowledge to have some background as to what you are formulating. Your lessons and mini books have really taught me so much in such a short amount of time. I am loving every minute of it! You make it simple easy steps to follow and it gives me the confidence I need to look professional in this new venture.

    Thanks so much!
    Take Care

    very helpful for starters like me…thank you!

  • Harry 02/18/2015, 12:29 am

    What a wonderful guide! I like the detailed instructions.

  • Vishwanaden 02/17/2015, 8:06 am

    It’s very interesting as a starting point.Thank you for sharing your knowledge.

  • Sam 02/16/2015, 4:02 am

    I skimmed over it and saw a lot of important points being made. I’m looking forward to reading it more and checking out other resources that are on your website. I heard about this site from an AIChE CEP article.

  • Tounie 02/15/2015, 11:32 am

    I am overwhelmingly optimistic that my formulating challenges will present with more ease in knowing and trying different avenues instead of grinding my teeth. Thank you for sharing your knowledge and understanding of a complex and secretive industry

  • Evelyn Fontanilla 02/13/2015, 5:05 am

    Very good material for starting formulators. It is also very good for those who would like to review on how to go about “duplicating” competitor’s formula

  • onels 02/11/2015, 2:33 pm

    Good, I like it, its working…

  • Jake 02/11/2015, 7:45 am

    Great report very helpful

  • Matthildur Thordardottir 02/10/2015, 3:02 pm

    Hi Thank you for this. It was very interesting reading and helpful for me. :-)

  • Chris 02/09/2015, 11:42 pm

    This is a good guideline to develop the cosmetic formulation in delicacy. It will be even better if included how to conduct stability test.

    • Perry Romanowski 02/10/2015, 7:59 am

      Hello Chris – we have a blog post on that subject.

  • joshua 02/08/2015, 8:50 am

    Awesome report. I really enjoyed reading it. I liked the manner in which issues such as what qualifies as natural or not and certification of raw materials were handled in the report.
    Well done Perry.
    Thanks very much for the insight.

  • Raheem 02/07/2015, 11:55 am

    Great information cant wait to read more articles!!!

  • el'amor 02/05/2015, 3:18 pm

    So much info and I love it it sure has help me. Meanwhile the online stores don’t send the purchased products to nigeria guess that be sorted out or are there other places to check?

    • Perry Romanowski 02/05/2015, 4:17 pm

      Yeah, I’m not really sure where else you might check. Alibaba might send to Nigeria.

  • debbi 02/05/2015, 1:37 pm

    Good info! Wish I had this info before starting to work on a formulating project for a client. I am a chemist and had little other than my qualitative and quantitative analytical skills when I started.

  • Karen 02/02/2015, 6:55 pm

    Great resource. Very informative and helpful. Thanks!

  • riviere 02/02/2015, 5:42 am

    Dear all
    I enjoyed the report, it was instructive.
    Thanks a lot

  • beautyqueen 01/31/2015, 11:02 am

    This has really helped me to realise that I can be a great entrepreneur and start to produce my own facial, body cream. its not as difficult as I thought I am so grateful to have come across your website as from now on I will keep my learning skills up to date and use your teaching about beauty chemistry. I want to be able not to worry about how to make great products specially as I am new to all the making from scratch part of it. So I want you to know that you have changed my point of view about the chemistry industry and that anyone who is willing can actually achieve what they want in the beauty business.

  • Marie 01/25/2015, 7:15 am

    Very interesting and informative. I am not a cosmetic scientist but I am formulating natural ingredients to make my own natural skin and hair care line.
    I am very new to this site (not even a week old) but I have learned soo much already, some truly amazing and some ever so shocking.
    Although I am not at the stage where I will be knocking off just yet, the report has given me insight to how to read formulas, % rule, how to source information and so much more.
    There is soo much amazing information on this site, I know it will help me to better formulate my products.
    Thanks for caring and sharing.

  • Jeff hogrefe 01/24/2015, 1:58 pm

    I have been working on a few formulations over the past 2 months. The article was encouraging in helping me realize that I am on the right path. Thank you for the knowledgable report

  • ehkamul haq 01/24/2015, 4:09 am

    Thank u very much for providing such a great information, i have learned very much from this info but i think u should provide that how to identify the cast of the raw material so that we can add the specific quantity to the batch, we should know that how much cast of raw material should be added in percentage because there is not any company who disclosed their formulation on sample products so u should provide a best info about how we identify that.

    Thank you !!!!!

  • Maria Ruiz 01/23/2015, 2:00 pm

    Muchas gracias por su libro acerca de como duplicar un producto cosmético, es muy bueno y de verdad, da muy buenas bases para comenzar.
    Solo haría falta indicar para aquellos que no conocen; el manejo porcentual de las formulas para facilitar su costeo y su adaptación a lotes industriales.

    Muchas gracias por compartir este tipo de información, perdón por escribir en español, es mi lengua materna y me queda mas fácil expresarme en ella. Soy Química Cosmética por experiencia pues trabaje 11 años en Investigación y Desarrollo de productos cosméticos en la industria

    Maria Ruiz,

    Thank you very much , great informations …

  • Jasmine 01/20/2015, 5:18 pm

    I loved it, I like how detail it was for telling you the steps. But i did not see it mention anything about start up cost and how much it would cost to to do all of those things

    • Perry Romanowski 01/21/2015, 2:24 pm

      We have another post about that. Do a search on the blog to find that article.

  • Kelly 01/16/2015, 6:30 am

    Informative but not as detailed as I was hoping for. I am trying to create a hair product and have all the ingredients but am having a hard time finding information of how to actually get started.

  • Emma 01/12/2015, 11:54 am

    Great general and basic information for someone starting out in the field! Thanks for sharing. I am eager to receive more articles from Chemists Corner!

  • Adib 01/12/2015, 12:36 am

  • pat 01/07/2015, 7:02 pm

    Hi Perry, I quite enjoyed your very informative tutorial on Cosmetic Formula Knock-Offs. I am a newbie when it comes to cosmetic formulating and so far have managed to formulate some great products, so much so that I don’t think I would ever turn back, your knowledge is exactly what i’m looking for, keep up the good work!!, I do have a query on step 7. Would it not be better to make small batches at 100 gr. rather then 400gr.? Thanks

    • Perry Romanowski 01/08/2015, 7:27 am

      400 g would be the minimum. Making 100g batches are too small since it introduces significant weighing errors

  • Hamid Gani 01/06/2015, 9:56 am

    “How to Knock off Any Cosmetic Product” was very informative and make life easy to get to know and make own cosmetic. Thank you for the honest and unselfish informations.

  • cassie 01/06/2015, 8:25 am

    Thank you so much! It’s very useful

  • Bernardo Mora 01/05/2015, 9:47 pm

    Very good job. Cool to educate people on cosmetics chemistry, so we can make educated choices.
    I salute your work, well done

  • Alicia 01/05/2015, 7:17 am

    This was a great eBook for anyone interested in learning the steps to take to make a product that you find on the shelves now. Thanks for breaking down the steps and making it seem less daunting! I hope that I can utilize this method to create some natural products at home and better understand the industry, should I decide to create a skincare business.

    All the Best!

    Its wonderful how you are so inspired to share with others. If i had more info this would have long orobably been my profession since college. Thank you for simpkufyibg and demystifing cismetic chemistry. The report is intuitive but lets me know im on the right track with my developpment project. Ps i love the new site.

  • Babs 12/29/2014, 3:11 am

    A very good resource. I found it useful in the sense that I have always wanted to copy a successful moisturiser but never thought of these steps.

  • John (braveheart) 12/27/2014, 7:50 pm

    It is like a compendium of all the knowledge I have tried to amass in the past two years of researching the industry. Perry makes it very easy to grasp and follow. Thanks.

  • Mahavir 12/27/2014, 11:07 am

    I learned about duplicating pastes, creams and other compounds; not only cosmetics but other products also. It was learning this specific art, at one place. Rare !

  • syed abdullah 12/25/2014, 2:45 pm

    wealth of information about cosmetic, detail comments will follow soon,thanks best regards

  • tari 12/21/2014, 4:45 pm

    Hi, i loved the opportunity to read about cosmetic formulation. i am a chem student. My Grandmother use to make her own skincare products. She was a wise woman and taught me many things about herbs and mixing them for my skin.When she passed I set this aside for years but I would one day love to have my own skincare line. The cost to develop products is very expensive but I know what to look for and questions to ask if I should decide to buy the base already made until I finish school.

  • Margreat 12/18/2014, 12:12 am

    This is a VERY thorough guide to re-creating a product. It gives a lot of information to anyone wanting to know what is required to copy a cosmetic product. At the very least, you will need to get a LOT of the product you’re trying to reproduce. Who knew? I’m glad I do this only as hobby! Thanks very much for providing it.

  • Veronica 12/16/2014, 11:10 am

    I don’t know how I found your website, but I am so glad I did. You share a wealth of information. Thank you very much!

    I hope for further guidance from you in future.

  • Paulene 12/08/2014, 6:00 pm

    I am not a professional cosmetic chemist. I do my own DIY formulations at home. Due to my sensitive skin, I have a couple of products that I intend to duplicate. Prior to reading your excellent article, I actually did steps 1-3, analysing ingredients and making decisions on substitute ingredients based on my customised intended outcome of the product, but skipped step four and went straight on t0 step 5. I will admit that I have not successfully duplicated any products as yet. However, I am confident your article will lead me in the right direction.

    There is a lot of excellent information and methods that as a complete amateur and someone that did not do that well in chemistry in school would never have thought of. Thanks so much for such generosity in providing this.

  • june lim 12/06/2014, 8:58 pm

  • Johan 11/24/2014, 2:54 am

    The cosmetic knockout article is great for beginners and experienced cosmetic makers, because if one uses the knockout approach you make cosmetics. This does not take anything away from the method, in fact it is a wonderful learning school for almost anyone interested in cosmetics. The article also reflects the huge experience of the author, which he shares freely with everybody.

  • Lori Lagos 11/20/2014, 11:08 am

    Hi, Thank you so very much for all this info….I have not had a real chance to read everything you sent as of yet. However I am very serious about learning as much as I can about this subject.
    Thank you

  • Joni Catanzarite-Pecsi 11/17/2014, 7:50 am

    I have been given the task of trying to duplicate a know product, and all I know about the product is the ingredient listing along with a 1.5 oz sample.. I was actually able to pinpoint the fragrance due to being an odor coordinator at a previous job, but had no idea where to go from there since this product contained a lot of extracts and a few surfactants that I had never worked with. So while doing my research I stumbled upon “How To Knock-Off Any Cosmetic Product” and knew it would be something beneficial to me, and after reading it I am happy to say that it has been extremely helpful. Being an analytical chemist, with primarily pharmaceutical experience, I feel the need to research all I can prior to trying to making a sample batch. This document has a wealth of useful information, and the 10 step approach has been extremely helpful to me.

    Thank you for providing this information.

  • gam 11/16/2014, 3:58 pm

    It was a great book and I still reading it.
    it learns me things that I don’t know befor , it is absolutely helpful like a guide to me since I am not an industrial

  • Tanvir Abdur Rahman 11/15/2014, 3:37 am

    Thanks for give the opportunity to leave comment. However we make Hand Wash and use SLS, Glysarin, Fine Gum or 600 Gum, Citric Acid, HB and MPS(as preservatives), but the problem we don’t get enough foam and after washing don’t get softness in hand rather hand becomes dry. We face more problem like in component we use pearl color but with Fine Gum pearl doesn’t stay for long.
    So please suggest me about High Foaming as well as moisturizing hand. And also suggest for a better Thickener.

  • keyshawn 11/11/2014, 6:03 pm

  • Jennifer S. 11/06/2014, 10:15 pm

    I thought I knew a lot about the business of beauty … I have been involved and studied this industry since I could practically read. I have done very well for myself and was hopeful of branching out on my own. Without knowing where to start I downloaded “How to Knock off a Cosmetic Formula” from Chemist Corner, to see if I would be able to learn anything I didn’t already know. I truly was ENLIGHTENED and was more than SATISFIED with the content and information that was given to me. It was extremely helpful and full of good factual information on beginning your own product resembling your favorite brand name. I have to say after reading it I feel a lot more confident dipping my hands in this MASSIVE industry. I would also just like to thank Perry for thinking of us “little guys” who want a chance to make something great. The knowledge that he shares on Chemist corner. Com and in his “How to Knock off a Cosmetic Formula”. Is extremely useful and truly blessing to anyone searching for a helping hand.

  • Anna 11/06/2014, 10:07 am

    The information I read is awesome. There are so many things that I learned and I was speechless. Thank you a million times for sharing the information with us. Now I can do things I couldn’t do before

    Recently I sent Mr. Romanowski an email and he responed back asap. Right there I know that his program would be something of interest. I also benefited from the information I was looking up. I even ask him some questions that had nothing to do with him or his business and he answered It with no problem. It’s not many people out there that will take the time out to help you. And Mr.Romanowski showed me that he can take the time out email attend to other needs regardless if their members or curious researchers. I just want to say Thanks to Chemistry corner and I definitely will be enrolling in your cosmetic science course online.

    Thanks for the information, I appreciate

  • Dakalo 10/15/2014, 7:51 am

    I found it very useful, it gave a lot of great ideas and starting points. I feel that it is however very “American” in some aspects e.g. in terms of how to get hold of some of the ingredients and in terms of the advice about patent search. Thanks all the way from South Africa though!

  • Sarah 10/14/2014, 10:39 pm

    I just graduated with a degree in Pharmaceutical Chemistry and have always been interested in learning more about cosmetic formulations. Thank you for getting me started on the right path!

  • Edison Subala 10/14/2014, 8:17 am

    Very helpful and informative. It cut down my research in half and inspired me to go for the cosmetics industry. This is truly helpful specially to those who are starting in the field. I am actually looking for somewhat “rule of thumb” or ratio for basic formulation on derma products like how much needed for at least the basic ingredients.

  • Melanie 10/06/2014, 2:41 pm

    Very helpful way to use another product as a starting point to develop your own. Saves a lot of time. The one thing I didn’t find helpful is that is says you can search the us patent office but their search engine is difficult to figure out. I wasn’t able to look anything up. Lots of helpful info though!

    • Perry Romanowski 10/06/2014, 5:19 pm

      Use Google Patents to search patents. It’s much better.

  • serene 10/06/2014, 7:02 am

    Thank you for the notes. It was very useful to me and I would like to appreciate your effort

  • Kevin Johnson 09/22/2014, 3:41 pm

    The e-booklet is filled with plenty of common sense things that can be performed to facilitate one’s learning experience. I’ve used other patent’s in the past to analyze medical instruments. What a great idea, in extending that venue to include cosmetics, especially if the patents have been well written because one may discover an entire chain of patents that cover the historical development of the patent that you are intent on learning from. Suggesting list development of agents, then linking them to their general precursor categories based on “action” is logical and a no-brainer if you’ve had any form of chemical analytical training. However, for individual’s that haven’t had that experience, its a great idea in learning about ingredients and how they may react in isolated conditions. There are many valuable tips in this book as I was surprised by the thoroughness of the author.
    Well done, indeed,

  • Judith 09/22/2014, 1:08 pm

  • Jose 07/28/2014, 10:57 am


    “How To Knock-Off a Cosmetic Formula” report is interesting and arises the reader’s interest on cosmetics manufacturing.

    Having said that and having expressed my gratitude for having free access to it , and must say that I expected more information about:

    how to figure out the class of ingredientes.
    how to search for a cosmetic patent and get its composition. For example, how to get the composition of Evening primrose shampoo for dry hair by john masters organics.
    how to analyze a formula.

    Additionally, I missed information about:

    the purpose of each class of ingredient
    the concentration range recommended for each class of ingredient in the diffent types of cosmetics.

    In a word, any publication should fulfill its purpose and I missed critical information in “How To Knock-Off a Cosmetic Formula”. But it was free and I am thankful for it.

  • samantha 07/27/2014, 4:50 am

    I need help with my compounding, when the temperature rises above 80 degrees the cream separates but when is below 75 degree the compound maintain its creamy consistency. I use coconut oil, grape seed oil, sunflower. I need some suggestion of how i can come up with better product that will not change as the temperature changes.

  • Jennifer 07/24/2014, 2:15 am

    The magazine was spot on. It teaches a lot of stuff though I think duplication of other people’s products is unethical and may be illegal in some countries. Would appreciate if product development information sharing became the core principle. Otherwise, great ideas.

    Happy Creativity.

  • kerry 06/09/2014, 2:55 pm

    Very good for a beginners guide. I was hoping the spreadsheet link also included % actives integrated into the formula. Seeing as many materials, most in fact, are not sold at a 100% actives levels (example: take 50% cortisone vs 75% cortisone and in the formulation to get the same activity level you would actually use less) Accounting for this additional factor would be a more comprehensive way of explaining the real world science behind it. Great job.

  • Leigh 06/09/2014, 4:21 am

    This is just the info I was looking for! So well written and concise. If only other course material was the same.

    I have been reading the book and I’m finding it informative, despite the fact that I’m not interested in duplicating anything that’s out there on the market. What I’ve discovered is that most of the cosmetic products on the market [99.9%] to be extremely deceptive and perilous to the user.

    • Perry Romanowski 04/28/2014, 7:06 am

      Cosmetics on the market are not perilous to the user. The advertising may be misleading but the products are hardly deceptive. They do work as cosmetics.

    Dear perry,
    I m developing my own cosmetic skin care product but I want to make it without preservatives. is it possible or not for all products ?

    • Perry Romanowski 04/18/2014, 7:35 am

      Making products without preservatives is inadvisable. Microbial contamination of products represents a significant safety issue. If you want to produce safe products you almost always have to use a preservative.

  • Susanna Jordan 03/15/2014, 5:57 am

    Thank you so much for this information. I am just getting started in the world of cosmetic chemistry and I am really such a novice at all of this. Initially I was worried that this text would be over my head but I was surprised to discover how easy it was to understand and follow this e-book. I love all LUSH product line and want to duplicate some of their products. With this simple to follow yet detailed book I feel more confident in experimenting with their formulas. I am ready to explore my inner chemist! Thank you Perry!!!

    Perry 44

    Dear Sir

    this proposal very interesting to know the chemistry of

    cosmetics in an appropriate environment, driven by you.

    With the name of “chemist corner”, I realized that I had to

    do with chemistry in general. therefore interested me.

    then I realized that it comes to cosmetic chemistry and

    I am production chemist.

    very grateful for your consideration.

    Currently my interest is to work in my area



  • di 02/11/2014, 3:59 am

    I’m so happy I got to sign up with this site. It is so informative and it’s a site I can trust. I love all the scientific articles and the fact that there is a forum to discuss cosmetic science with others. It’s a great place to really delve into cosmetic science and start learning. I’ve learned so much the past 2 years reading blogs and joining forums, it’s like I took a college course in CS for free. Some sites require proof you are a company, have your own product line, etc, before approving you to join. I was happy to be able to easily join such an informative site. And the free articles are great!! I love duplicating my favorite products, so it was so awesome to see I got a free article on breaking down and formulating duplicate products!

  • marta 01/29/2014, 9:39 am

    I really loved this, it’s really hard to find such practical information. I’m fresh out of pharmacy college, and have been fascinated with cosmetic formulation for a long time. I’ve been doing my own experiments for years. My goal some day is to have my own small cosmetics business. With very little experience other than my own experiments and non-specific college education, and after going through books and books of theoretical cosmetic science, I’m thrilled to find such specialized hands-on texts.

  • Hector 12/26/2013, 2:08 pm

    The free ebook is great for starters. Being trained in physics and biophysics (working at a university) I find such book very interesting and full of sense. I have developed some formulations for different skin conditions, from scratch, going over the peer-reviewed journals and “mom’s and grandma’s advice” :-) I do this primarily for my family and friends as a hobby; at least their comments are great! Hope to learn more in the near future! thanks again…

  • Alex Byarugaba 12/13/2013, 4:35 am

    I am a chemistry graduate so I found the material interesting, but discovered that I am already doing most of what you recommend already on my own steam. Waiting to see what you will come up with next.

  • Tanja Koštomaj 12/12/2013, 5:29 pm

Reading through the hype of cosmetic companies is entertaining and to begin to understand the chemical invasion is almost scary. Your book is a great bonus and so glad to discovered your website. Carry on the great work!

  • Abdalla 11/05/2013, 11:23 am

    I’m doing my Ph.D. Research in Evaluation of the concentration of Toxic metals in cosmetics in SUDAN, it is some sort of comparison studies between imported and local cosmetics (specially those used as a whitening agents and Hair dyes).
    It would be grateful if you support my research because we have notice many signs indicating that unsafe cosmetic preparation might causes many health problems .

  • SHIVA M 11/03/2013, 2:36 am

    Hi Perry,
    It is great and invaluable information for all of our cosmetic formulators and specially for the beginners. Let me share my little experience to your visitors about one of the useful websites helping to formulate appropriately. It is ” http://www.personalcaremagazine.com “.

    Thank you again,

  • Yvonne 11/01/2013, 2:06 pm

    Extremely useful information. Not being a cosmetic chemist, this document actually provided a systematic approach to basic product development. I have been making good use of the info provided. This is step 1. Thank you.

  • Rosa 10/31/2013, 10:00 am

    I think this e-book is quit informative and useful but only if you are starting out .Developing cosmetic formulations is not so easy.

  • yvonne 10/19/2013, 5:39 pm

    Hi Perry,

    Very useful information. I have always been interested in doing reverse engineering on some products I’ve used that proved to be very effective. My idea is to understand the composition take out the bad stuff and improve the formulation for added benefits.

    I am curious though, are these companies completely honest in listing all their ingredients when it can be easily copied. Where is the competitive advantage in that case.

    • Perry Romanowski 10/20/2013, 3:57 pm

      Yes, they list their ingredients. In the cosmetic industry, it is marketing that sells most products not the performance of the products. Just because you can copy someone’s formula does not mean that you will have a successful product line. People buy cosmetics because of good marketing.

  • Babak Gh. 10/18/2013, 11:38 pm

    Thank you for everything. I need many new formulation about personal care, please help me.

    • Perry Romanowski 10/22/2013, 12:14 pm

      See our post on sources for free cosmetic formulas.

  • Kallia 10/18/2013, 8:55 am

    It’s a very useful collection of all the necessary information that someone will need, if he/she is planning to have a project on this field. As a chemist I found it quite informative and very easy to read! Thanks a lot

  • Alisa 10/18/2013, 1:05 am

    The booklet fed into my “mad scientist” side. I have been doing many of those things since I was 13. I would go to the cosmetic counters and ask to look at the products while I study the ingredients list. Every time I read about a new skincare or haircare product in Vogue or Allure, I immediately research the ingredient list and try to figure out how I could do a better formulation. I thought I was the only one that occupied herself by being such a sleuth. I am always curious what makes a product work or not work and what would make it better. I did not learn so much as I felt emboldened and encouraged to continually try to take the best products in the industry, make them better by tailoring them to my needs, getting rid of the ingredients that don’t really add anything, and adding ingredients that would have a better synergy … I love finding out that I am not alone in my favorite hobby.

  • Merryl 10/15/2013, 6:00 pm

    Thank you for your information. The more I delve into the world of cosmetics, the more I want to learn. As a learner, I found the 1% rule very interesting & the fact that surfactants & thickeners etc. are more important than the actual actives in a formula.

  • phu 10/12/2013, 2:30 am

    for the beginner and having no basic on chemmist like me, this report is extremely useful. It gives me the very visual image.
    I still have some questions on reading this:
    – Step 4: plz tell me more about how to get patent from the website of united state patent office
    for e.g: I want to get patent of the product Fruit of the Earth, aloe vera gel, so what should I do?
    – Step 5: How to analyze the formula if I don’t have analyze machine or lab? What can I do instead?


  • V.R. 10/09/2013, 6:28 am

    I have some experience in this area, so there weren’t new things for me to find out. However, I think article is good, well written and can offer a lot of useful information for someone who is new in this area.

  • Henry 10/08/2013, 4:13 pm

    Thank you! I found the approach very useful and realistic in application and potential execution.

  • Ray Hauser, PhD 10/07/2013, 1:37 pm

    I’ve been developing some unique anti-itch lotions during the past many months, and might have made faster progress if I had read your Knock-Off book earlier, but I wasn’t trying to match an existing product. I have improved such lotions considerably. I question whether your suggestion on page 20 to add salt to adjust viscosity, when gellants are much more effective but take some learning on how to use them. I’ll pass the notes onto a new assistant.

  • VMose 10/06/2013, 5:13 pm

    I learned a lot of good info from this manual, and yes I must agree…I took all those chemistry courses and really there is nothing practical that I learned so that I could apply the knowledge towards creating products. I mean yes, you learn how certain molecules bond and why. I would definitely be interested in learning more about cosmetic chemistry.

  • Alex 10/05/2013, 10:05 am

    I had taken one of your SCC courses before and found this to be consistent with the excellent presentation then. I appreciate your ability to “teach to your audience,” if you know what I mean. I look forward to getting more educated from future sessions. Thank you.

    I found this booklet provide a lot of information for cosmetic chemistry.

  • Marina Todorov 09/30/2013, 12:30 pm

    Very informative, interesting and useful.Thanks!

  • Carley Macaluso 09/30/2013, 10:20 am

    I just started my career in Cosmetic Chemistry after the last 5 years in the biochemistry industry. This was very helpful in getting me familiar with cosmetic formulations and terms. Thank you.

  • Nia 09/30/2013, 10:08 am

    After reading the material, I was surprised that you could use patents to your advantage in making cosmetics. Interesting tidbit!

  • Tracey 09/30/2013, 4:26 am

    Very informative, it will be helpful in future formulating

  • Mohammad Tavakkoli Yaraki 09/30/2013, 12:48 am

    I wonder if there was more information about the mechanism of this action. What is important to scientists, in these types of product, is how these products really work and description of mechanism. The results are not important alone.

    • Perry Romanowski 09/30/2013, 2:32 pm

      We cover that kind of information in our training course.

  • Peggy 09/29/2013, 11:59 am

    I thought that US companies could keep some ingredients secret as “trade secrets”, however in Canada one must list all ingredients. Your report says otherwise. I have also noticed that in Canada there are companies such as Arbonne that do not list all their ingredients.

    • Perry Romanowski 10/02/2013, 9:42 pm

      Companies are supposed to list their ingredients on their packages.

  • Morry 09/29/2013, 11:29 am

    I truly admit that your HOW TO KNOCK OFF ANY COSMETIC PRODUCT report very informative. It is a good first hand manual to our beloved cosmetics, giving tips which to me if well studied will generate new and innovative cosmetic formulations. Thanks. I’m yet to practice them and if questions arise i will surely let you know. Again, thanks.

  • uri 09/29/2013, 2:18 am

    “How to Knock Off Any Cosmetic Product” was enlightening, and very interesting. I was glad to see that it had a down-to-earth tone, free of commercial hype. This is refreshing in a world geared towards consumerism.

  • Uong Duong Cam Tu 09/28/2013, 10:40 pm

    It’s very informative, I’ll understand applying chemistry in comestic clearly. I hope you’ll send me other parts of course. Thanks a lot

  • Carol 09/26/2013, 2:11 pm


    One would have thought that formulating a product for cosmetics would have taken the world, but your article gave so much info that can make even an interested novice go about it with ease. Please keep up the good work and keep it rolling it.


  • Sheikh Dastagiri 09/23/2013, 12:29 am

    It’s impressive.

  • Racheal Lewis 09/21/2013, 1:27 pm

    It was a very good read. It gave good insight in how to approach formulation and save time. I will definitely use this approach once I start to work in Research and Development.

  • LouLou 09/16/2013, 12:01 pm

    Thanks Perry for the information

    I found it most informative, especially as someone who has practically no knowledge of chemistry!

    I am looking for a chemist based in the UK who can help me develop a range of products – any ideas of how to go about finding one pls?

    With thanks


  • Helen 09/14/2013, 6:28 pm

    Hello! I felt it very informative! I learnt so much. My only suggestion would be to be more specific about how to blend ingedients. (Im relstively new to the chemist industry). Can this process be done at home? Or do you need a lab and specialist equipment? Do u just mix all the ingredients together? Or do you need to heat them up? More clarification would be much appreciated!

  • santi 09/13/2013, 12:49 am

    very good, i got some experiences from that book.

  • Ngotrang 09/12/2013, 8:49 pm

    I just want to let you know how thankful i am for your sharing knowlegement. It is so helpful. It leads me to where i want to go.
    Keep moving :x

  • Shawn 09/11/2013, 12:33 pm

    This is a great guide. I’ve been attempting to duplicate a cream that is no longer available for a friend, and this guide, with it’s easy and common-sense steps, has made the process so much quicker and easier. I don’t know how long it would have taken me to get the product right (if at all) without it. Thanks!

  • Rachel 09/11/2013, 10:53 am

    Your material is very helpful to me. I had an idea for a product, but, although I am a chemist by training, I do not have any experience in the cosmetic industry at all so I felt overwhelmed. Looking on the net I came across your guide and it was just what I needed to get the “bigger picture” of the whole process, including marketing, the legal side etc.

    I look forward to the Cosmetic Science Introduction Course. Thanks!

  • Kristal McCool 09/09/2013, 12:33 pm

    I really enjoyed “How to Knock off Any Cosmetic Product”. The report let me know that I am on the right track and pointed out some things which I did not know. It gave me a step by step process on how to get my product more in line with what I had envisioned and the report showed me how to look at other products to determine the reason behind the ingredients listed.

    What I am currently trying to do is make my own base. By following the precepts listed in the report, I should be able to get to my destination faster than I had previously anticipated. I’m also learning a bit more about chemistry and it is a world full of excitement and adventure.

  • Sylvain Bellerose 09/07/2013, 5:49 pm

    Thank you. This ebook was very interesting. Easy to read and informative.

  • Mitch 09/05/2013, 7:13 am

    I was impressed with the thoroughness of the report. I didn’t think copying a formula would be so intricate. Thanks for the hard won knowledge.

  • mellynne 09/04/2013, 7:18 pm

    very helpful info nice read very informative. thanks great that its free :o)))

  • Linda 09/04/2013, 5:26 pm

    This report was excellent for people like me who always wondered how it was done. Enough detail to be practical, but not overwhelming. I enjoyed learning the thought process from beginning to end. Thanks!

  • Zorka 08/31/2013, 12:07 pm

    Hello,Thanks for really good informations and very usefull ,also.I just start to use it and I hope to read more.Regards!

  • yohan 08/30/2013, 10:11 pm

    Great, It was very helpful and informative for me as beginner – I will try to make my own formula and start for new bus. Looking forward for the next information. Thank you.

  • sarah mahfouz 08/30/2013, 2:58 pm

    I find pretty much useful , especially at this point of my career . thanks

  • Sankar Jayaganesh 08/30/2013, 6:20 am

    it is a quite informative booklet. Easy to understand format. Your website also wonderful to search any kind of en query. thanks for your service.

    kindly give me the one short term course book..

  • Sankar Jayaganesh 08/30/2013, 3:30 am

    very informative. give the useful information to develop any kind of product. it is small compendium of formulation chemsitry basics. thanks… and keep it up…..

  • Keneesha 08/29/2013, 5:07 am

    Excellent document! I really appreciate that it provides an approach re-verse engineering products in “non-chemist” terms. Now i can better use my resources to help with understanding ingredients, selecting equipment and improve my overall product outcome.

  • Dan 08/26/2013, 3:00 pm

    This is great. The day after I read this I was looking at ingredient lists in the store, trying to deduce the 1% line.

  • Ester freitas 08/25/2013, 11:34 am

    I found the report very informative and clear. For me, a beginner in the area, every trustfull and practical, piece of information that comes to my hand, is of great utility. This report was quite practical and was direct to the point. Easy to read, simple and short as the information should be. The subject itself was very useful, because for the beginers like me, we suspect that the number of copies or near copies should be big in the market, but we always fear to be inspired in competitors, and to fear to do benchmark is an error. It helped to clarify how to behave in this market in the commercal level.

  • Nelly 08/23/2013, 5:51 pm

    Hi Perry,

    I found your report very informative. Great info for a beginner like me. I hope I’ll e able to take your course soon. I ‘m very interested in your course for more in depth info. Thank you.

  • sudha 08/22/2013, 10:20 am

    “How to Knock out a Cosmetic Formula” is an informative document giving a broader perspective to a formulator. Though I formulate and test prototypes in a lab yet there is so much more beyond that to learn. This is evident from this document.

  • Biljana 08/22/2013, 8:06 am

    Thank you for sending me this e-book. It explained the concept of cosmetic to product formulation. I liked the best example of formulation technique. Excellent guide on practical information about cosmetic science. It provides an overview of Product Development: How a Raw Material Becomes a Cosmetic.

  • Gloria 08/20/2013, 11:41 pm


  • Erin 08/20/2013, 12:46 pm

    “How to Duplicate Any Cosmetic” was fun to read. I am currently looking to further my career as a chemist. I want to learn about all the raw materials and how they interact during manufacturing of cosmetics. Just making the cosmetics isn’t enough, I want to understand exactly what is going on! I found a place to start looking.

  • Pradeep Deo 08/20/2013, 9:23 am

    Dear Perry , Have been in the Essential Oil and Spice and Botanical extracts industry and always had interest in Cosmetic formulations. Have been interacting with a lot of Cosmetic formulators – especially on the Fragrance and in the development of Active Botanical Ingredients and related product development. Even though , have been doing a few things what has been suggested in the 10 step system without actually knowing about it formally , your Report has given me a fresh insight and would definitely help me in approaching new tasks with a much greater clarity and discipline ……. Incidentally , I happen to interact with a lot of Food Processing companies who are trying to developing products in line with the Market leaders ……..Feel , the 10 step system would apply and hold good even for Food products too…………….

    • Perry Romanowski 08/20/2013, 11:11 am

      Thanks for the info! Hope you find the rest of the information we provide helpful too.

  • Raphael 08/16/2013, 3:56 pm

    Hello Perry,
    Thank you very much for the e-book “How to Knock off Any Cosmetic Product” that you sent. I found it very comprehensive wit a lot of useful information. It was very thoughtful of you to compile this report.

    Thank you once more

  • Solange Peretti 08/14/2013, 2:28 pm

    Hello Perry !
    I’d like to thank you for the e-book “How to Knock off Any Cosmetic Product” that you sent and give my feedback about it. It is a very useful e-book ! I’m from Brazil and here is kind of dificult to find books about this subject, it is really inspiring to me and I’m happy to know that the work that I used to do here is almost the same that some cosmetic chemists do in U.S. (as you showed in the book)! One new thing that I learned from the book as the “1% rule” I did not know that . So thank you !

  • nulambeh jim 08/13/2013, 4:15 am

    hi sir am really glad to part of this program. sir i will really like to have information on chemicals that can cream(change ones color) the body from black to white rapidly without causing harm to the body. also how can i order for such chemicals as soon as possible. all these demands is because i run a beauty center here in my country and there is a high demand for mixtures that can change ones color from black to white. i will be grateful if my request is granted.

  • Tom 08/09/2013, 5:42 pm

    I found your report to be very informative with important links to information. I have a couple of books related to this field but your report was easy to read and cut through all the fluff. My interest was in patenting of formulations and I wondered how your “knock off” book would affect my thinking. That will take some time but I will let you know. Patents are supposed to disclose but how much to they protect? If a formulation is as easy as you say to knock off, then trade secrets are a waste of time.

  • Diane 08/08/2013, 6:53 pm

    The “How to Knock off Any Cosmetic Product Report” is informative and very helpful for me as a starter. Thank you

  • katt 08/03/2013, 10:37 pm

    This was a very informative and simple read for beginners! I’ve been a “kitchen witch” all my life, but have only been taking it seriously for less than a year (although very intensively). Im preparing to enter our local farmers’ markets, and this guide was very validating to me to assure that I have been instinctively doing a number of the recommendations in the book. But it also expanded my knowledge and provided me with more resources to take the next step to create a professional product that is competetive.

  • Rabi Ekore 07/30/2013, 1:52 pm

    I found the ebook quite interesting. It gives a beginner a good guide not only on how to reproduce existing formulae but also on how to go about creating their own formulae. And the adivce on producing in very small batches is a valuable one, as it helps to save cost. However, I would like to see a section with a very practical example, for example, producing a particular face cream from start to finish. Thank you for all the information provided. The book is an okay guide.

  • mezan 07/30/2013, 6:23 am

    i want to take a practical training on that , is it possible ? if possible pls give me a chance . i will pay for this

  • Karen 07/29/2013, 5:21 pm

    As a sales rep, relatively new to this industry, this was very interesting to me. It helps me understand the steps my clients are taking when they are creating knock-offs or even developing something new. And it helps me to understand how the ingredients I’m selling will be used. I can speak more intelligently on this topic now. Thank you!

  • Michael Fields 07/27/2013, 12:46 pm

    It is a great place for newbies like me to start. I have only been in the cosmetics industry one year. I was a flavor synthetic chemist in my previous job. I greatly enjoyed reading it and it is going to help me in new directions our company is trying to take. Thank you very much.


  • Maira Simoes 07/27/2013, 7:21 am

    “How to Knock off Any Cosmetic Product” is a comprehensive, very useful and well informative book. There are really good clues, mainly for those starting as a cosmetic formulator. It´s not so deep (and we are advised about that during the reading), but is an excelente good start! Thank you for releasing a material like that!!!

  • Ed Ladores 07/26/2013, 10:53 am

    I really did not expect to find a website as informative as this. I’m involved in crop protection chemical formulation but would like to explore the potential of formulating shampoos to control red mites of fowls. Your site has drastically reduced my problem. It was really a big help to new probable cosmetic formulators!

  • Domnina 07/25/2013, 4:40 am

  • tee tee 06/27/2013, 4:56 pm

    The advice offered was specific, concise and practical. All the necessary information was given for items not provided in the book which saves the reader the time and energy to do that research. Furthermore, being that the source is reputable, one can feel confident in the information.

  • Raj 06/26/2013, 8:55 pm

    Very interesting!
    A good starting formualtion procedure to follow, especially for those still learning how to formulate simple creams and can move on to more complex formulations.
    Good to be part of such an organization and get help to develop formulation skills.

    Great guidelines to begin with. They will definitely save a lot of time and sweat for me. And also I would really appreciate it if you continue with Volume 2, something like: “How to alter the original formula to improve it and better suit your needs” ;)

    Brilliant teaching approach, Perry.
    Thanks a lot!

  • sash 06/12/2013, 6:25 pm

    Thank you for this report, I was tasked with an idea! Could we make our own product to sell? This paper has been my the basis of my initial response…yes!

  • Ms Deborah Jenkins 06/10/2013, 7:54 am

    Thank you, I appreciate the well organized, step by step process you describe. The fragrance has been elusive for me and I haven’t found a good source. I would also be interested in a scientific method on how to distill active ingredients from my favorite botanicals. Thanks again for your book!

    • AndyH 06/10/2013, 1:09 pm

      Hi Deborah,

      Again I find myself responding (apologies for my enthusiasm having being in the industry for so long!).It can depend on your location geographically to find a perfume house to cater for your needs -depending scale, quantity, price and availability.

      There are numerous suppliers locally or through agents who can satisfy demands from minimum quantities to bulk – depending on
      your manufacturing requirements.

      As regards to distillation (not as straight f0rward as you may think) there are smaller suppliers who specialise – but you will need to
      spend time sourcing these reliable specialists – although major fragrance houses will oblige [quantity viable].

      What I would advise is to source your favourite botanicals from a reliable supplier (of which there are many) and would suggest essential
      oils rather than absolutes due to the cost of such!

      If you require botanical extracts – a rather different ‘kettle of fish’ again there are many reputable suppliers who can supply ‘regular’,
      or ‘organic’ versions depending on your requirements.

      Good luck!



  • Leah 06/06/2013, 6:37 pm

    Hello! I am so happy to have found this website! And thank you very much for putting out this publication – I found it to be incredibly helpful! Its funny when I think about it – I never thought I or anyone else would be able to make a cosmetic product- I guess I always thought robots made them or something! haha You know I always read the ingredients before I purchase a product – a lot of them look so complex and technical (this coming from someone with a background in Mech engineering..) – it never occurred to me that the public had access to these ingredients and that I could actually mix them together to make something that worked. Thanks again!

  • A ELBADRY 06/05/2013, 10:05 am

    Thank you for the effort and precious info. I’m looking forward for more info.

  • Gill 06/04/2013, 12:10 am

    Overall I thought a helpful report. I was pleased that it reinforced what I already knew, which was reassuring- while also offering some new ideas.

    One area I have some questions on though- As you state: Ingredient listing is meant to be in order down to 1% and then 1%, and below that, in any order.

    However when an ingredient is a blend of several components/INCI labelled compounds, often the supplier /manufacturer does not give the relative proportions of those individual ingredients. So while the formulator might add the blend in at say 3% the individual components of the blend wont be their at 3%. In this situation what is the formulator meant to do when listing the ingredients?

    In (most?) instances I suspect that the formulator just lists the ingredients details of the ingredients sequentially and as it is very difficult to tell what groups of ingredients represent blends from the ingredient listing, this could be misleading. I am aware of some ingredient blends that are sold which contain more than of 6 listed ingredients . Any thoughts on what to do to identify and deal with these situations would be appreciated.

    • Perry Romanowski 06/05/2013, 8:29 am

      You should really never be in a situation where you work with a supplier who won’t tell you the relative proportions of the ingredients in a mix. At the every least they need to tell you what the INCI label name would be given your formula.

      In truth, if the ingredient is used at less than 1% then it doesn’t matter. And that is 1% active. Most ingredients that are a mix of 6 or more ingredients are typically mostly solvent.

  • BARNABAS 05/30/2013, 2:45 am

    This is great idea to develop the cosmetic formulation in duplicacy. But the question is dont realy understand what is all about. thanks

  • Catherine 05/29/2013, 9:24 pm

    I think this report is clearly written and very helpful to those who want to knock off a formula. Would be great if you explain deeper into each topic, but thank you!

  • Lac 05/28/2013, 11:51 pm

    Thanks for the info.very helpful

  • Ghassan 05/28/2013, 6:35 pm

    If you allow I have a question about the installation of cosmetics:
    At any stage I can modify the pH of the cream during manufacturing, by citric acid or lactic acid, without separation occurs between the oil and water phases?
    What is the appropriate emulsifying agent (I use glycerol monostearate in the oil phase and Triethanolamin in aqueous phase)
    I thank your wonderful work

  • Ghassan 05/28/2013, 6:22 pm

    Thank you
    But I have an additional question, please, can I replace the salt sodium chloride and ammonium chloride salt in the same proportion?
    Can I use magnesium sulphate with Lauryl sulfonic acid to get the shampoo does not tear the eyes? And if so; does add salt (sodium or ammonium) or rest on it and realized viscosity too?
    Finally Can I use tylose the viscosity to raise? When can I hold added without that happening during the conglomerate added?
    Then what is the damage to the hair of this added?
    Thanks for your attention

    • AndyH 05/29/2013, 2:16 am

      Hi Ghassan,

      In answer to your question, I would suggest the following;-

      1. Use Ammonium Laureth Sulfate 70% as your main active ingredient (6 – 8%)
      2. Buffer with Ammonium Salts (phosphates) (0.5-1.0%).
      3. Use Cocamidoproyl Betain approx. 5 – 7%
      4. Use Cocamide DEA approx.0.8% (keep minimal)
      5. Thicken with 0.7-1.0% of Ammonium Sulphate dissolved in 5% of the batch water.
      6. Other ingredients to suit your intended shampoo.

      You may need to ‘juggle around’ but this does work.

      Hope this helps,


      • Ghassan 06/03/2013, 5:32 pm

        Thank you very much for this information, but I think that the percentage of (Cocamidoproyl Betain approx. 5 — 7%) very high , Because it is what I think of the Quartet amines that may lead to dry hair .

        • AndyH 06/05/2013, 11:39 am

          In response to your comment regarding Cocamidopropyl Betain – this is an amphoteric/zwitterion surfactant and helps to reduce the irritant effect of anionic surfactants (i.e. your primary active).
          The level of 5.00 – 7.00% (corresponding to 1.50 – 2.10%) is by no means excessive as you are reducing the Cocamide DEA, which
          is more of an irritant and has a greater drying effect.
          To further combat drying/irritation, it is useful to add PEG-7 Glyceryl Cocoate at 0.50 – 1.00% which also gives a degree of moisturisation and results in an even milder product.

  • Irma 05/26/2013, 11:31 am

    Hello Perry,
    Thank you so much,you are helping me to shorten the learning curve and focus on what is important.
    I would be interested to know what lab tests you would do on your sample beside pH, sensory assessment etc.
    I am looking forward to receive your mini lessons. Thank you for sharing your knowledge Perry.
    I have health science,biochemistry,microbiology and pathology background. Formulating is my hobby and obsession.

  • Efi 04/26/2013, 6:45 pm

    Thank you Perry for this free copy of your ebook. I only wish I had read it earlier, 7-8 years ago when I started working as a cosmetic formulator!
    Usefull tips for the beginners, described in a simple language. It is a great suprise to me that you freely share your knowledge through your work because I am facing a great secrecy regarding formulation and very few people have the knowledge or the will to help.

  • iswanto 04/25/2013, 11:50 pm

    It is something new for me as a pharmacist, yet it is not only informative but also inspiring.

  • mary morris 04/25/2013, 9:04 pm

    I quickly read the report, and it contained much of the information I thought it would. Very informative and thoughtful. I would like to read it again. It appears to be done professionally, friendly, and thoughtful. I never met a chemist/pharmacist I didn’t like. I have little spare money right now (that is why I started making my own products), so I can’t order the course right now. I wish I could. But, I would like to, and most likely will reread the intro when I get some me time. Thank you.

  • Oprah 04/25/2013, 3:21 am

    I absolutely loved this ebook! I have to say, it’s one of my best downloads of the year! I’ve been researching and experimenting for almost a year now and love the easy approach this book has. Lots of things I didn’t know to do. Like patent searching, sample requesting, and calling suppliers. Great book!

  • Nicole 04/22/2013, 7:07 pm

    As a novice this was very helpful in understanding the function of each ingredient and therefore the percentages. Well laid out and written in an easy to understand manner.

    I would love to say it’s a good report, however i downloaded and it won’t let me read it just says unsupported file

    • Perry Romanowski 04/24/2013, 7:57 am

      When that happens, most people can get it by ‘right-clicking’ the link then choosing “save-as”. Then open the file from your computer.

  • Shereen 04/19/2013, 8:55 am

    The “how to knock of any cosmetic product” report was very informative. I’m a novice in cosmetic chemistry and are interested in learning more. Really appreciate having this information freely available.

  • Dennis 04/18/2013, 4:31 pm

    I have found the reading to be very interesting. I have used some of the points you have indicated over the years and there are other points I know I will be able to use to sharpen my R&D skills. I eagerly await more knowledge.

  • virginia bonofiglio 04/18/2013, 2:54 pm

    I thought the article clearly pointed out how easy it can be to “knock-off” a product. Gave a very concise answer to the question.

  • IK 04/18/2013, 12:59 pm

    The Guide is practical, concise and relevant. We always learn from others even if copying formulas is not the type of business we are in.
    Thank you!

  • Georgia 04/16/2013, 10:29 pm

    There is so much information in that small report! I am having a hard time with formulas & the report goes into a L O T and at times seems a little confusing to me. Some of it is going into stuff I am not interested in doing like making a business of it, but overall it is very well put together, thank you.

    thanks very much perry. i have never immitated a formulation before, i only work on standard formulations, although i am new in the cosmetics industry , but i found the write up very precise and educating at least i have gained knowledge on how to start.


  • Andy H 04/07/2013, 7:38 am

    Dear Perry,

    As an experienced formulator – I started in 1982 my mentor and guide being a pioneering Aerosol Chemist [also adept in toiletries] and your guide
    is exactly the way I learned my skills [I had to start with 1950’s formulations to understand the basics] before progressing to modern formulations.
    I would thoroughly recommend this guide to ‘novices’ and newcomers alike.
    My only comment is that there are few anomalies that need ‘tweaking’ – nothing serious and few additions that may have been overlooked and I would recommend – purely from a personal viewpoint.

    That aside a very good and informative introduction to any newcomer – keep up the good work!


    • Georgia 04/16/2013, 10:36 pm

      I am having trouble with a recipe saying to add 8% of a ing. to which the recipe says 6ml of following ess oils (5 seperate) with 8% of lavender the rest (4) will make up the total. Does that make sence 2 u? Anyway I did not know how 2 calculate it.

      • Perry Romanowski 05/08/2013, 10:59 am

        Hello – you should post this request in our cosmetic science forum.

  • Andy H 04/07/2013, 7:19 am

    Dear Perry,

    I found the introductory of a cosmetic formula an extremely informative guide for the beginner and would recommend to any ‘novice’ or newcomer to this industry.
    As an experienced formulator – this is exactly how I learned my craft starting initially in aerosols and progressing into other areas of fragrance and
    toiletries – I started in 1982 under the guidance of a pioneering aerosol chemist and equally apt in toiletries – so I had a good grounding [I digress].

    My only real comment is that there are a few salient points I think, that could be added but that apart a very good pointer, well thought out and
    well structured – keep up the good work!

  • Joy Gee 04/03/2013, 4:13 pm

    As a layperson this treatise was wonderful to read as it gave me easy-to-understand, useful information. Consequently, I immediately ordered your book, The Beauty Aisle Insider, as I’m very interested in this topic. I look forward to reading it.

    Thank you.

  • mo 04/02/2013, 7:07 pm

  • Mitch stucker 03/23/2013, 7:16 pm

    It is a great resource for those who want to do that, but I am more at the level of Susan Nichols series of eBooks at the intro level. I am at the friends and family level and being retired, have no interest in the liability exposure at my age. Thanks to your journal reference, I now have quite a bit of good (and somewhat contradictory) info about the possibilities of oil and butter “essential” ingredients actually getting to where they need to be to affect the effects as the claimants would like to be true.

    I’ve just read “How to Knock off Any Cosmetic Product” and I think it’s a good introductory document and a useful guideline. I‘ve huge experience as a formulator chemical for household cleaning products for surfaces and only a small experiencie as a cosmetic formulator. Nevertheless, the procedures for knocking off any kind of product are essentially the same. I completely agree with the steps mentioned.
    It has a easy reading even for foreing students and profesionals as is my case.

    I found the report to be a fairly good introduction for some, though I had already worked out, through simple logical deduction, more or less the same processes on my own. I do not make knock-off products however. Rather I look to successful products and try to improve them in various ways, especially by eliminating and replacing synthetic and (potentially) toxic ingredients with safer, more appealing substitutes.

  • Kate 02/26/2013, 7:50 am

    I am just starting my own cosmetics line and found that I was already doing many of the things that the free report said to do. I am a Chemical Technologist and in my opinion the report on “How to Knock Off Any Cosmetic Product” was accurate and concise. Even if you don’t have any training or experience in chemistry you should be able to follow the method in that document and create decent products. In fact, even if you’re just trying to make your own stuff without necessarily copying anybody you still need to do the same things. How can you possibly begin to make anything if you don’t even know what’s in it? It’s a great little document, especially if you don’t know chemistry- it is written so that anyone can understand it and apply it and achieve success. Happy formulating, everybody!

  • OLYMPIA 02/26/2013, 1:33 am

    I have benn formulating my own products for about a year now and still I find the report very informative! Thank you for passing it through!

  • Jess 02/25/2013, 9:08 am

    As someone returning to the formulating side of Cosmetics, this was great recap and helps you think about formulating in a logical order.
    An interesting read.

  • lana alsharkas 02/22/2013, 3:48 pm

    Actually, it is very simple and could be done easily any where using simple equipments. In addition, it includes sufficient resources which make it easy to obtain the needed informations , but I think it is hard to find patents for products that arn’t made in US..thank you, really usefull…

    • Perry Romanowski 02/24/2013, 1:27 pm

      You just need to use Google patent search.

  • saade rifai 02/20/2013, 11:43 pm

    I have not formulated any cosmetics before although I have had a long standing interest in it. Now I am ready to explore the interest for possible entrepreneurial venture (if successful). Your report & mini-course should hopefully help me get started.


    • Imane Soubra 02/21/2013, 4:55 pm

  • Kingsley Kesiie 02/20/2013, 9:06 am

    This report is like a road map that gives confidence to any determined entrepreneur to arrive at destination point of money making in the cosmetics industry. It has really boosted me toward my goal of wanting a piece of the pie in the anti-perpirant deodorant industry (both the Roll-On and the Retractable Stick type). I am not a chemist; only some high school chemistry knowledge and a strong desire to make money in this line of product. If anybody can make this journey easier for me I am all ready for it.

    Offered.. But it has been of assistance to me.
    It’s nice to be given free advise as this is an exchange
    I like to offer also to customers.
    Thank you

  • Mickaila 02/16/2013, 11:32 am

    The book was great! Very informative.

  • David 02/13/2013, 11:13 am

    I found this information very exciting and has encouraged me to invest my little resources in cosmetics. Many successful entrepreneurs in cosmetics in my country do not even have knowledge in cosmetic science

  • Bernadette 02/13/2013, 8:21 am

    this was informative. thanks

  • Krissie Bak 02/12/2013, 8:21 am

    So helpful! It really gets me interested in pursuing a career as a formulator

  • Graham 02/10/2013, 9:59 pm

    Good solid info. probably could have saved me 2 years to get to this stage!


  • Akihiro 02/10/2013, 9:41 pm

    It was a great informative tool for me to understand what formulators need.

  • Jeffrey 02/07/2013, 7:44 pm

    It is such a good material, I’ve shown this to my colleagues who just started their career as cosmetic chemist. I found it also a good tools for training and orientation. A very good strategy as a fastest and easiest approach in improving an existing formula. Thanks Perry

    • Perry 02/08/2013, 8:18 am

      Thanks for the kind words Jeffrey & for spreading the word about Chemists Corner.

  • Ingy 01/31/2013, 2:49 am

    Thank you Perry for the report, i found it interesting, informative and well-organized. It is really a good start for chemists and researchers who are interested in Cosmetic Formulary. I would like to thank Chemist Corner team for their great help and support. I wish you all the success!

  • Isza 01/31/2013, 2:41 am

    The report is alrite for me. This is good for those who are into duplicating cosmetic but not looking further into making from scratch.

  • elita 01/30/2013, 10:09 pm

    Great source of information. Makes total sense and shows that I been on the right track all along. What I really enjoyed was the links.

  • Marina Giorgii 01/29/2013, 10:32 pm

    The report is excellent for its purpose, and it would be useful to me if I wanted to do just that- copy other cosmetic products. But what I’m really after, for now, is the basic knowledge/tips/principles on how to mix simple, natural ingredients for my own personal use, how to make base lotions, creams and serums- and how then modify/add to them. I really never liked anything available on the market, and I’ve tried many products, some more, some less expensive. Most skin-care products contain preservatives, synthetics, and other toxic chemicals (even if some of those are proclaimed harmless), too much fillers, and not enough active ingredients. At this point, if anything seems to be even remotely suspicious, I don’t want it on my skin. That disqualifies most of the personal care products from my use. As a first step, I’d like to be able to create my own fruit acids gel/mask of any concentration/strength I desire. Second, I make my own liposomal vitamin C (for internal intake), and I’d like to incorporate it in my potions, so I need to know how to mix it with oils, for example (such as rose hip seed, my favorite), how to add other vitamins, etc. I don’t have much interest in replicating existing formulations because, as I said, I’m not impressed with them. Simply exfoliating my skin with some enzymes and glycolic acid, and following that with pure rose hip seed oil, improved my skin more already than any commercial products I tried so far. I just want to take what I’m doing now one step further.

  • Karen 01/29/2013, 11:40 am

    Hi Perry,
    I found the “Knock of” info really helpful. I took down all the links you suggested. I’m new at this and really want more info. I’ve got a ton of actives and bases and want to get started.

  • Caroline 01/20/2013, 7:16 pm

    Thanks to the chemistcorner I enjoyed it a lot.

  • Alexandra 01/17/2013, 8:41 am

    Thanks for allowing a free access to this report. I have a grad. degree in cosmetic chemistry, but for several years now working in organic chemistry, so it was good for starting to up-date my knowledge.
    One more time thanks and good luck with further projects!

  • Verdeeks 01/17/2013, 4:39 am

    I really enjoyed reading the article. I am a chemist and a “wannabe” cosmetic chemist. I thought it was very informative and made me want to get in the “kitchen” and try some things out! It was an excellent intro but I feel like I missed some of the basics. Personally, I want a more thorough intro to raw materials.

  • Jean 01/13/2013, 4:18 pm

    I would say “How to Knock off Any Cosmetic Product” is so informative, even i am doing PhD on trans-dermal delivery, i am refreshed with all the useful tips! Thanks, Perry!

  • Renato 01/13/2013, 7:54 am

    Very good, interesting.
    Waiting for new projects.

  • M.Nadeen 01/01/2013, 2:10 am

    The information contained in “How to Knock off Any Cosmetic Product” is the practical know-how in a nutshell which leads a layman to create like some expert any composition of a formula. Thanks to the uploader

  • Usman Dar 12/26/2012, 6:20 am

    I am very impressed and want to take active part with you.

  • Donald 12/20/2012, 8:45 pm

    thanks for the copy. I never knew that such platform exist before. So educative. Thanks alot

  • Rob, NZ 12/19/2012, 3:17 am

    Hi Perry,

    A great read. Some stuff I knew already, but enough tips to assist further. Last time I ripped a formula, I used Karl Fischer to determine moisture content, and using known values ( such as Carbopol 0.3% typical usage rate) and worked out the rest from there. I think a combination of what you do is fine.

    I am looking at studying cosmetic science to fill in my knowledge gaps. I typically tend to formulate capsules, softgels, tablets etc and not too much in the cosmetic field.

  • RICHARD MUGISHA 12/16/2012, 8:47 am

    This demystifies formulation of cosmetics. Iam impressed.

  • Régis 12/14/2012, 5:41 pm

    This is very informative and clear. Thanks a lot Perry!

  • Kedi 12/10/2012, 9:52 am

    Nothing I did not already know but a good read.

  • Frank 12/09/2012, 5:01 pm

    Thank you so much for the copy you sent to me. I just read it now. It’s quite informative, full of tips. Thanks for the good work. I am not a science student but i so much like science. I have been reading some books online concerning formulating for almost a year now. I can now produce soap, cream, shampoo, perfume, hair relaxer, etc. Though, am still doing more research. Thanks again:

  • louise 12/06/2012, 2:26 pm

    I found this to be an informative and methodical reference with a few new ideas to work with.

  • Hasmik Houlder 12/03/2012, 11:25 am

    Hi Perry, the report was very informative, thanks. I am at the stage of researching the cosmetic chemistry field for establishing my own company in the future. But I have a question. When I want to get free (or even purchase) samples of any raw material for formulations, is it possible to get it through the companies without having my own already set-up company? Will they provide their sample materials to an individual?
    Thanks, Hasmik

    • Perry 12/03/2012, 11:30 am

      In most cases, you are going to need to have an established company before a company would send you a sample.

  • samantha 12/03/2012, 12:28 am

    Hi perry

    Whilst this did give a taster I then went on to look at the course because it may be something i am interested in, but here’s the deal I think this course is very much geared for people like me who are starting out in a career in cosmetic chemistry or a home crafter formulater the problem is i am not enticed enough? I mean you don’t really tell me fully what i am getting for my money there are no sneak previews of recipes nothing except your video, so I quickly lost interest, you need to draw people in more!

    • Perry 12/03/2012, 5:57 am

      Hello Samantha. The course teaches you the science behind all the formulations, the relevant marketing, the formulation and testing. Everything listed on this page describes all the features and benefits of the course. What more would you like to know?

  • Kalidah 11/27/2012, 8:19 am

    I found the “How to Knock off Any Cosmetic Product” to be informative to newbies and a refresher to people more versed in cosmetics.

  • Julie 11/23/2012, 10:25 am

    This guide was very methodical and logical and I received information from it that was new and insightful. I will be referencing this method as I develop new products.

  • Helena Ribeiro 11/22/2012, 8:07 am


    I´ve just arrived to this fantastic industry after long years on food industry quality control. Although much more pleasent, this “world” is also much more complex…

    I’m trying to start some basic formulations on moisturising cream and shampooing and your book is a great contribute for my previous research.
    Thanks a lot!.

    Most of the info in the report was already familiar to me, however, the section on surveying patents was an idea I had not thought of. A useful piece of information. Thanks.

  • Serina T. 10/18/2012, 1:24 pm

    A very informative article on the basics of how to knock off a cosmetic product. While it is a great starting point, it would be nice if more detail was given on certain parts to really make it more useful.

    Great information if you are just “getting your feet wet” and don’t want to create your
    own formulas or have no idea how to start creating your own. I like that you gave some websites.
    Hunting for different sites can take so much time and when you’re a beginner—you don’t know where to start.
    I wish I had found something like this when I first started out.

    I do have a few questions that I would like to ask you before I take the online course with you .
    Do you have a professional email address that I can send my questions to ?
    I wouldn’t want to ask my questions publicly .
    Thank you very much ,

    • Muhammad Junaid 10/17/2012, 9:16 am

      Hi i read your mail in cosmetics i am a chemist and also interested in cosmetics but i have little knowledge in this respect would you to exchange it?

  • sargon gorjian 04/11/2012, 4:21 am

    I found the book very useful. I myself have knowledge about using oil, surfactant, emulsion, preparing aqueous and oil layers and mixing together without forming 2 layers. I liked to see one or 2 examples for a cream preparation using different oils.

  • Anna 04/10/2012, 7:44 pm

    Thanks for the free e-book Perry! It was packed with useful information, epecially the advice on resources. I also appreciated how user friendly the information was for the wannabe chemists.

  • CCM 04/10/2012, 6:37 pm

    Nice intro into cosmetic chemistry with some very informative links to start some serious research. You won’t be able to make a product from this book, but it can help point you in the right direction for the rest of the info you need to make one

  • Jeremie N. LUBIBA 04/04/2012, 7:12 pm

    Dear Perry,
    I just read your little book on how to imitate any form of a cosmetic product.
    This is really interesting and it’s what I wanted to learn for some time. It is clear, precise and directly usable. Thank you very much for this document.
    But in addition, I am interested in the training that you give through your website but I am in Africa where we have no broadband here as the United States. What alternatives do you suggest?
    Also for practical training, would I be able to come to work in your labs here in the U.S.?
    When I write these words, I am in your country where I could easily follow your videos.
    But, how to follow the free high speed internet?
    I am a pharmacist in the industry since1994, I think my previous experience will help me learn better. Do you believe it too?
    I want to register immediately but I await your response.

    Jeremie LUBIBA

    • Perry 04/09/2012, 7:18 am

      Hello Jeremie,

      Thank you for the kind words. I would suggest you look into Cosmetic Learning since they have an option where they send you a set of CDs for study. Good luck!

  • Lady 04/01/2012, 9:07 pm

    Thank you for this informative piece. I look forward to doing my own formulations in the near future.

    Again, thanks much

  • Miakia 04/01/2012, 8:19 pm

    I thought the information provide was quite informative , I paralytically found it interesting as I just switched fields.The links where also very good as well . Love the fact that you got to the point very quickly as I can be very impatient when reading, I tend to hate the gilding of the lily so to speak .

  • Melany 04/01/2012, 4:48 pm

    I love cosmetic! I would like to be in this industry!!!!
    Thank you some much for the usefull information!!!

  • ayurshi 04/01/2012, 2:24 pm

    i want know more about cosmetic technology field, scope, sumthing new which we can creat of our own in formulations………

  • Joseph Allaire 03/31/2012, 2:18 pm

    I thought it was a very useful article. I usually just focus on creating new products, never really got into knocking others off. Thanks for the info.

  • Jen 03/31/2012, 1:50 pm

    Great tips

  • Tere 03/30/2012, 7:54 pm

  • Tammy B 03/10/2012, 10:23 am

    Thanks much for the free ebook. I am not a cosmetic chemist by trade but study as much as I can for my business. I formulate my own bath & body products. I did find some useful tips in the report. Thanks again.

  • SC 03/08/2012, 12:02 pm

    Thanks for this report. It was really helpful and it inspired me to get out there and give it a shot.

    I think the report is useful as an introduction to the cosmetic formulation.

  • Lance 02/27/2012, 7:02 am

    Thanks Perry, the guide is refreshing as some previous responses put it, but also fully useful indeed. For instance, I never thought of scrounging eBay for ingredients and it turned out a pretty good experience.

  • Melin 02/26/2012, 5:36 pm

    Great eBook on duplicating a cream. I am really looking forward to the other information coming. Could really use some info on finding suppliers so I will look around the site! Thanks

  • David O. Bidot, MD 02/25/2012, 4:10 pm

    Thank you for your free copy of How To Knock Off a Cosmetic Formula.
    So far what I have read, has been interesting and very useful and has also encouraged me
    To continue on my interest in learning how to create cosmetic formulas.
    My main interest at present is on facial cleansers.

  • Lindsey 02/24/2012, 8:31 pm

    I’ve just recently become interested in cosmetic chemistry and your website and all of the articles are amazing and very informative. Thank you so much!

  • Shahbaz 02/21/2012, 2:38 am

    Hi Perry,
    I have read some part of ur report. It is great, I will read it completely in near future as soon as I get some time. I am formulating a clear Hair styling wax, I am having problem as it is less sticky to hair and on cooling it have a separate top layer. i am using Ceteareth-20 , Glycerine. and another experimental sample turn hazy it additionally includes the following conditioner d-panthenol and a silicon conditioner.
    please guide me as i am a beginner in this area. Thanks!

  • Nancy 02/18/2012, 9:47 pm

    This report, and your web site are just what I was looking for. Well written and easy to understand. Thank you!

  • Nicola Rigby 02/16/2012, 5:44 am

    Not of any particular use to my current work but would be good for someone working within this area – concise and comprehensive report

  • Patricia 02/13/2012, 10:15 am

    The information given is exactly what I was looking for. I intend on making my own products and start a business, so I think the report will give me my start on my chemist career. Thank you.

  • George 02/13/2012, 8:34 am

    The book on How To Knock-Off a Cosmetic Formula is very usefull, easy to read and understand. I just have two questions? One, what do the numbers after the ingredients listing of many products mean (ex. ) and two how can you search for a specific product’s patent using the United States Patent Office site or any other site?

  • Susan Shi 02/12/2012, 9:03 pm

    it’s wonderful?but easy to master. Thanks Perry.

  • Susan Shi 02/07/2012, 11:06 pm

    I’m a formulator, I think the ““How to Knock off Any Cosmetic Product” report is very helpful to me. Thank you very much. I love this website.

  • Giuseppina Viscardi 02/07/2012, 3:33 am

    This report gives you the basis to start formulating and also give you practical advices to use your creativity and create new formulations. Very helpful if you are approaching the cosmetic field

  • Mavis 02/05/2012, 12:43 pm

    Hi Perry,
    Thanks for the book, I have been looking for such information for ages and glad finally found it! The language used is so simple that a beginer like me found it it very easy to understand and follow.
    Thank you for helping x

  • Josh Cummins 02/03/2012, 12:05 pm

    I found this guide, “How to Knock off Any Cosmetic Product”, a useful and general source for cosmetic formula replication. Being a analytical chemist with formulations experience I would say that this guide should be mandatory for all of those looking to create their own cosmetic formulas. This approach make the most sense for those with a limited budget and with little experience in the cosmetics, formulations, or chemistry as there is a myriad of poor and simply incorrect information available on the subjects.

  • Lisa Leigh 02/02/2012, 6:12 pm

    hi – Loved the book – it was simplified and easy to understand. Regarding the fragrance, what if you don’t want a fragrance added to the product? Some people are allergic and prefer fragrance-free products. Would you use some kind of masking agent to cover an unpleasant-smelling product? Thank you. Lisa

  • elise 01/31/2012, 10:28 am

    took this in from an esthetics standpoint and thought the information was easily digestible and a great gloss over how to knock off a product.

  • fahad 01/30/2012, 5:02 am

    Great and informative ………….learned lot

  • cathy 01/29/2012, 8:24 pm

    I plan to use this book to train new technicians in our formulation lab.

  • Danny 01/27/2012, 1:36 am

    This is an excellent book which is very easy to understand and practical. This book tells you how to make a product step by step and I believe this book will benefit many people.
    I do have a suggestion. Mining patents is an excellent idea, but for many people it is a big challenge. If the author can have a similar book with examples to teach people how to do it, I will definitely look forward to reading it very much.

  • alshams 01/26/2012, 9:58 pm

    I loved it. I found the book to be both informative and interesting.

  • raymond 01/26/2012, 6:40 am

    perry where do i get the mini free course

  • raymond 01/25/2012, 2:29 pm

    its not a question of nocking of a product but having some knowledge to understand how to enjoy making cosmetics.the book is informant
    and i enjoy using this sight .yes i think we are all keen to learn,and i believe we can learn from you.

  • Shafik 01/25/2012, 7:29 am

    The “How to Knock off Any Cosmetic Product” report was quite informative and useful.

  • Timothy Rukuni 01/25/2012, 12:20 am

    I did not managed to download the Primer on Natural Cosmetic Formulations from all the links provided. They just lead me to blank pages. can you help?

    • Perry 01/25/2012, 5:52 am

      You have to have a PDF reader installed on your browser. If you do not, right click on the link then ‘save as’ and the file will be saved to your computer. Then you can open it from there.

      • Timothy 02/17/2012, 10:16 am

        Thanks. The report is my new companion in my quest to become a cosmetic formulator. Thanks so much for providing such information.

  • Jacky Choi 12/15/2011, 7:30 pm

    Very practical points!
    I think it is a very good piece of hints and setps of going deeper to the formulation of other products we are interested and helping us to create a similar formulation in a faster way.

  • Ayana 12/13/2011, 10:32 am

    I think it’s a pretty decent starter manual. I was at first bothered by the idea of a ‘knock-off’ product but I realized that copying products can serve as good starting points for beginners in the cosmetic industry. I did learn useful info from this :)

  • Kelly 12/12/2011, 2:56 pm

    It was interesting to learn about all of the available sources to get ingredient and formulation information

  • KeShawn 12/10/2011, 8:37 pm

    The report was informative for a novice.

  • Isabel 12/09/2011, 5:39 am

    It is a great report for begginers in cosmetic formulation, like me! I had success with skin cleansers formulation but now I have to make an invisible gloves protecting cream, that will act as a second skin, to be used by workers who dealt with dangerous solvents. It would be helpful to have more informations related to formulating emulsions and specialized lab tests for skin lotions.

  • Ishaq 12/08/2011, 7:59 am

    have received the report and am looking forward to reding it soon.

  • aram 12/07/2011, 5:34 am

      Its fantastic and worthy reading for beginners.

  • Ravi 11/18/2011, 12:12 pm

    Being a chemist for more than 5 years I knew most of the material given in this brochure, but it was very well outlined and will be extremely useful when it comes to training new chemists and teach them the ropes. Thanks for putting it together.

  • miguelmines 11/17/2011, 5:38 am

    Very interesting your “How To Knock-Off a Cosmetic Formula” report.
    I have been toying for a couple of months with the idea of getting your
    “Complete Cosmetic Chemist Training Program” which I found in
    cosmeticsandtoiletries.com. I guess your mini-course can give me a
    better insigth of what your training program offers to a beginner.

  • Brenda M 11/14/2011, 4:03 pm

    found the article educating and inspiring to create my own beauty product

  • La Tronda Lumpkins 11/14/2011, 2:38 pm

    I found the “How to Knock Off Any Cosmetic Product” report very useful. I have been formulating my own all natural products for years and just launched a business selling the products. However, there are some formulations I would like to perfect but just do not have the time to put into the innovation. Knocking off helps me look at areas to develop as a formulator. I would love to take an online course to learn more about the process. Also, I would love to learn more about how to convert measurements and weights into percentages. This is an area I have not been able to figure out just yet. I noticed the report suggest making assumptions in the percentage in formulations. Your website is a wonderful resource. Thanks a million!

  • barbara 11/14/2011, 8:07 am

    Great basic information for the beginner! Thanks for organizing the information and publishing it!

  • Anne 11/04/2011, 4:12 am

    Great info!

  • Christine 11/03/2011, 8:38 pm

    I bumped into this website by chance and loved what I saw. I am just starting out in this field but have no chemistry background, only basic physics. Learning new things by the minute so hopefully, will catch up soon. Lacking knowledge on what the standard measuring/mixing proportions of substances, types of equipment typically used, and where to purchase. Will appreciate any help or info that will help a virgin-cosmetic-chemist.

  • Barbara 11/03/2011, 9:24 am

    Thanks a lot Perry for your book,
    I found your book almost by chance surfing the net … It took my attention I read it and found inspiring.

  • Liliana 11/03/2011, 4:39 am

    Very helpful guide! Reverse-engineering a mixture where the ingredients cannot be separated can be a tough challenge.

  • Janet 11/01/2011, 12:38 pm

    An important part that is missing is pricing out the formulation. At least a “ballpark” figure on cost of the formulation (per lb, per kilo, per ounce) without packaging should be given. There might be active or other ingredients that are too costly for the customer, especially is the
    customer has a price range in mind.

  • lia 10/31/2011, 6:21 pm

    Love it! It’s like an insider’s quick guide to a career in cosmetic science. It reveals all the small details unavailable with just college chemistry courses.

  • Bliss Mutangiri 10/31/2011, 6:09 am

    Having dreamed of making cosmetics and having no exprience in the cosmetic and science field this was an eye opener to me

    thanks a lot for your concerned ,but i have already finished this step of my career and start making my own formulations.
    My difficulties are : how to make a large amount of my products ( my formulations stable when i make my products in small amount)
    and now i also looking for raw materials are cheep and with the same time have good qualities.With that i can make cheep products with high quality.

    Thanks again.

    I found “How to Knock off Any Cosmetic Product” to be very informative. I have zero experience with the chemistry end of cosmetics, but after reading How to… I feel more confident as I move forward into my venture.

  • Rutendo Linah 10/13/2011, 7:17 am

    Hello, Thank you soo much for the “How to knock off Any Cosmetic Product” it was exactly what I was looking for. I am a chemist by profession but have never been exposed to the synthesis side of cosmetics so I am very grateful.

  • jp 10/10/2011, 8:06 am

    It’s a basic guide, maybe a roadmap with some useful links to get one thinking about how to proceed.

  • Adri 10/06/2011, 9:36 am

    This is a perfect overview of the process. Food for thought for those who are reluctant to give away their formulation to EU-safety evaluation! The chemical analysis of target products will hardly be necessary for experienced formulators. The same applies to all the claim support equipment mentioned in “Specialized tests”. My suggestion is to elaborate a little on the stability testing additional to the reference given and to add safety evaluation principles. Thanks!

  • Evie 10/05/2011, 11:12 pm

    It was extremely informative, and has made me rethink, perhaps to create a knock-off product, then make it better…..YEAH! Thanks heaps

  • Erica 09/29/2011, 6:34 am

    What can I say, it has helped me so much been new in the game I still use it. Thanks so much for all the helpful information.

  • Yah 09/28/2011, 8:45 am

    I found this incredibly useful. I will definitely be developing this skill and ‘Beginning Cosmetic Chemistry’ will certainly be on my desk soon. Thanks guys.

  • MK 09/28/2011, 2:08 am

    Hi “How to Knock off Any Cosmetic Product” is very useful especially for me because now I’m currently enrolled in a MS Course in Cosmetics Science. It was a big help for me since I’m still a newbie in formulating different products. The ebook was a big help for me. I just want to know more about trouble shooting for a certain product what to add to increase viscosity and vice versa things like that. Thank you for the ebook.

  • Seagull 09/20/2011, 10:47 pm

    It is very very good. I love it. I thought “How to Knock off Any Cosmetic Product i” opened a door for me. Thank you!

  • Marci 09/20/2011, 4:05 am

    Thank You for the eBook download.

    I’m not a formally trained cosmetic chemist, but I do have a strong background in chemistry, biology and nutrition. My interest is in hair care, and I have been researching information for a while now (which is how I stumbled upon your website). A lot of the information in the eBook I already knew; however, there is a LOT that I did not know, so again…Thank You!

  • F.K. 09/19/2011, 2:53 pm

    I’m learning a lot with the book.

  • Mark Berry 09/09/2011, 7:32 pm

    I liked the read on knock offs with the in depth extended approach. It reminded me that looking a little deeper has its rewards. I wonder if you could tell me where to find the article on common problems of thickening and thinning results with thickeners. I’m working with peroxide and it’s difficult to keep it thick for extended shelf life.

  • Michelle 09/02/2011, 10:38 am

    I find your website to be informative and a great asset for a formulation chemist. I stumbled upon it by accident and am very glad that I did.

  • Tasha Kopf 08/30/2011, 7:25 pm

    I’m a starting my own hair care line specifically for people in the agriculture industry and stumbled upon this website and the report and I love it! This website has opened up a lot of really good information for me and the report I think will be a crucial part in my future success. Thank you so much and the information in this report is amazing!
    Thanks again!

  • cheryl 08/29/2011, 8:10 am

    I am a beginner soap maker, and also intend to make other cosmetics such as lotion, body wash, facial care products, etc. The paper was very interesting, although I have not had a chance to read it thoroughly yet, I will. Thanks very much for all the information.

  • María del Rosario Calvo R. 08/29/2011, 7:52 am

    Muy interesante!!!!!! la secuencia de pasos a seguir para la formulación de productos cosmeticos. Ideal el hecho de identificar las funciones de las materias primas y agrupar las mismas según el % en el que intervienen en la formulación. También es muy buena la guí­a en relación a la secuencia de pruebas que se deben realizar hasta la obtención del producto final.

    • Ernesto Leon 10/06/2011, 10:00 am

  • Michelle 08/27/2011, 10:40 am

    I’m an esthetician who is looking into going back to school for chemistry and ultimately join the cosmetic chemists out there, so this is a whole new learning experience for me. So I know I am getting a bit ahead of myself being on here but I always enjoy going to the chemist corner. Thanks Perry

  • Janine 08/22/2011, 1:46 am

    This download was extremely helpful but I would have liked more guidelines on how to determine the 1% line. The example in the book was easy as fragrance was rather the line but for many formulations things such as fragrance etc are not present.

  • Phunchitta 08/21/2011, 10:21 pm

    That’s really good for starting formulate formulation that we want to do (knock-off).
    1% Rule can applied for all product and make adjustment by searching for the recommended range used.

  • Paolo Ferino 08/18/2011, 3:16 am

    Thank you for the download. It is my first job in this industry. It’s easier to formulate a cosmetic product. I’m a newbie in formulating but I feel like a pro. :) Thanks,sir!

  • Debbie P 08/17/2011, 10:07 pm

    Was a great read. I did learn a few things.

  • Kristy Richards 08/11/2011, 12:22 pm

    Thank you for the download! It captured me and I am very excited to learn more about working in the cosmetic industry- which has always been my dream. I am currently a regulatory/analytical chemist working on foods, but am anxious to begin learning about cosmetic chemistry!

  • Tracy Anne 08/08/2011, 8:12 am

    I thought it was really interesting and gives further insight into the industry and different types of formulations which is an eye opener for anyone new to the industry.

  • Abigail Buina 08/04/2011, 3:18 pm

    i liked it. to me it was an experience because there is little cosmetic science knowledge where i am. so reading the report was very revealing to me. actually thinking of doing my final year project in chemistry on cosmetics

  • Florina 08/04/2011, 1:42 pm

    The report was a good read.
    chemicalmatt’s comments were extremely useful too and I am glad he took the time to write.

  • Deb Seewald 08/04/2011, 12:51 pm

    I thought the report was great and your reminder to read it timely as I was just asked to dupe a foot cream. I also appreciated chemicalmatt’s addendum as this particular cream seems to have a great number of ingredients below the 1% line and the ‘general rule of thumb’ stated will help to make some sense out of all of them. Also, I did look this up in patents and it was not there. However, this companies preservation system was, so that will help too.

  • David Childers 08/04/2011, 10:31 am

    The information was geared for the small company with limited resources. The advice was very practical and easy to apply to formulation development.

  • Rario S. Santos 08/04/2011, 9:04 am

    What are the molecular formula for Dimethicone and Carbopol 940.

  • Maryam 08/04/2011, 8:40 am

    Thanks alot.I enjoyed the report.

  • chemicalmatt 08/03/2011, 4:20 pm

    Regarding “How to Duplicate a Cosmetic Product”, a fine work Perry.

    Some corrections:
    Iodopropynyl Butylcarbamate is an (antifungal) preservative, not a “solvent”
    Tetrasodium EDTA is a chelating agent/preservative, not an “adjustment”

    Some suggestions:
    In Step 3, pages 13 and 14, the ingredient breakdown by the 1% Rule. It may be advisable not to de-emphasize the <1% content. In the example given, the Polyquaternium-10 level can make a marked difference in outcome if it is at 1.00%w/w or at 0.10% w/w in this body wash. Perhaps it would be wiser, on page 14, to state:
    The formulator can later prioritize the <1.00% ingredients by function. This will provide insight into their concentrations, since the “less than 1.00%” may be listed in any order on the LOI. Some general rules of thumb can be applied (and this can be extrapolated much more):

    0.50 — 1.00% conditioning agents, sensory modifiers, rheology modifiers, emollient oils, surfactants
    0.20 — 0.60% fragrance, preservatives, adjusters, proteins
    <0.20% extracts, exotics, color stabilizers, colorants

    On Page 16, Step 5 “Analyze the Formula” can be much more explicit. Given that the example is an easy one (body wash), mention should be made about emulsion analysis of creams and lotions (which includes hair conditioners!). E.g.
    Determine if the product is a water/oil or oil/water emulsion. Most are the latter. If unsure, test by measuring conductance (in milliohms) relative to water. W/O emulsions will have poor conductance. A simple test is to add a dollop of the product into a glass of water and observe its behavior; or add a dollop of water to a small amount of the product. O/W emulsions will dissociate in water unevenly and incompletely, as an oil slick at first. W/O emulsions will dissociate evenly. If you add water to them, they usually just thin down a little, without dissociation. Also, look at the first two or three ingredients that you’ve identified as “surfactants” and look up their HLB values or their function from literature. If the primary surfactant (first or only one listed) possesses low HLB value, the product is likely W/O.
    Regardless of the emulsion type, you will need to rough calculate the “oil load”, or the nature of the product’s disperse phase for O/W emulsions, or continuous phase for W/O ones. Though often recognized as the amount of oil payload being delivered by the formula, this can be more thoughtfully considered as the ratio of oil payload to emulsifiers. Sensory feel will lead the way here (see Step 2!), once you’ve determined the solids level. A short playtime on the skin with little observed emolliency lends itself to a low oil load (1.5:1 or less). Exceptions to this rule abound, notably when cyclomethicone or isoparaffin is involved. Creams and lotions exhibiting a richer feel will generally have a higher oil load (2:1 or more). Some creams and lotions will feel very heavy, even greasy, leading you to deduce a high oil load, which is a typical of some “skin butters”. Some W/O emulsions carry an oil load of 20:1!

    Likewise, this step needs to better emphasize water content, often the most crucial step in saving time in duplication of water-based formulae. If the reader is a novice, you might flush out the method more. You may want to add:
    If you have access to an accurate balance, then weigh out 10.00 grams of the benchmark product onto a tared Petri dish, watch glass, or even a ceramic cup saucer. Place this in a convection oven, like you have at home, for 2 hours at 125C or 250F (no more!). Record the net weight then return it to the oven for another hour to note any significant loss in mass. The total loss in mass comprises mostly water, but may include alcohol, cyclomethicone, fragrance and other volatile components, so compare to the ingredient listing sequence to further deduce the water concentration. The mass of the residue after drying divided by the original sample mass will be your % total solids, which will be a most useful value in determining concentrations of the ingredients and of the oil load of lotions and creams.

  • Dr. David Melumad 08/03/2011, 12:50 pm

    Hello Perry,

    Thanks for your comprehensive and systematic approach.

  • Clare D 08/03/2011, 10:23 am

    Really good reading. I think there were elements I definitely already do – but it was good to see I am on the right lines! :-) For those new I think really, really useful.
    Thanks Perry!

  • Lamice Dfouni 08/03/2011, 4:31 am

    Information are clear and usefull especially for batch scale up
    To complete the work we refer to the Begining Cosmetic Chemistry book
    Links make work easier
    Thanks Perry

  • Sujatha 08/03/2011, 1:56 am

    Hello sir,

    I got very useful information by reading that. Your site is a good guide to develop the new formulations for the innovative formulators. Thank you so much.

  • Dianne Caine 08/03/2011, 1:54 am

    I have found this to be very useful, I have been making cosmetics for 10 years now and there is always room for improvement. Although I like to have my own fomular’s this is a great way to get more information. I had to do it all the hard way. I wish I had of found you a lot earlier in my formulation days..
    Anyone thinking of going down this path, its the best industry I have ever been in. I have been sucessfull in having my own brand now. So go for it…

  • Mark Fuller 08/03/2011, 12:22 am

    I enjoyed the report. It was really encapsulated the process.

    People may feel that they never need to duplicate cosmetics. As a Consultant Formulator I am often approached to do a knock-off or duplicate a standard. Oftentimes it is by the owner of the Product who no longer has access to their Formulas. A little known fact is oftentimes Contract Manufacturers will charge a large fee to purchase the Formulas. In some cases it is easier to have the product duplicated by a third party. This can present the client with an opportunity to refine or improve the product.

  • Lidgan 08/02/2011, 11:52 pm

    An excellent primer for newcomers, the links and tips are very helpful. Duplicating successful formulations is the first step in the path to innovation, it is a way to learn how to formulate innovative products, take a look at the video “Everything is a remix” in the following link http://vimeo.com/25380454

  • Pat Tyson 08/02/2011, 7:53 pm

    It is all very logical. I might not ever try to exactly duplicate a cosmetic, but you have given me a roadmap that I can use should I decide to do that.

  • quyet le 08/02/2011, 6:55 pm

    It’s very helpful to me. It helps me understand how to formulate. Thanks a lot!

  • La'Tasha 08/02/2011, 6:30 pm

    Great information. It was a very useful tool when formulating my first product.

  • andrianto 08/02/2011, 6:08 pm

    Yes, “How to Knock off Any Cosmetic Product” is great help to me.
    1. I found many usefull sites and follow their RSS Feed.
    2. Especially info about Patent Office, do great help to my job.
    3. I have guidance systematically & efficiently to copy a product.
    This is very great for someone back to workforce after long hiatus…:)

  • mohammed hafez 08/02/2011, 5:29 pm

    Information is important, valuable, and very impressive
    I think he is an excellent report, or a wonderful book
    But we need more
    We need your help in how to design blends for skin care and skin
    I personally had the skills and expertise to the work of skin-lightening cream and cream weaken hair follicles in unwanted areas
    And a bath oil and shampoo for hair
    But we need more, especially how to add natural oils and herbal extracts
    I hope to provide further information
    I wish you lasting success and thank you for this wonderful work

  • Jimmy 08/02/2011, 5:06 pm

    Great information for a beginner like me chemist corner keep up the good work.

  • Alison Nally 08/02/2011, 5:04 pm

    Great article for new chemists just getting into the business and a good reminder for all!

  • Jill Jones 08/02/2011, 3:48 pm

    I read this report when I signed up about a year ago. It was informative and easy to understand. Knowing how existing products are made is helpful when formulating a similar type of product. Thanks!

  • Nancy Piscatello 08/02/2011, 3:18 pm

    Thanks for the report, it made me realize I wasn’t on the wrong track by trying to, at first, copy another successful formula. It was most informative on the steps to copy a formula, but there are so many variables, that things can become unclear. I’m working on a lip gloss and found that my formula was coming out too oily no matter how many times I copied this other companies formula and no matter how many variables I altered. If you upped the oils to soften the formula: too oily; if you upped the waxes: it became too solid and not as softly “gloppy”, if you will.
    So, even though the report answered the basic “how to copy” and made me realize that copying is the surest way to find your own formula, it still left me with so many more questions.

  • Jerome 08/02/2011, 2:10 pm

    I had been using a similar approach and some of his detailed suggestions have been helpful. There were some very practical suggestions/instructions that I wish I had come to realize before. However,there are some complex balances that are needed to put a stable formulation together and one suppliers raw is not the same as the next, I did not get that from the article. It is far more complicated than the article implies.

  • TGrier 08/02/2011, 2:03 pm

    I think you provide a good overview of the observations, resources, and methods used to create a knock-off. Any time an individual provides insight into the actual work that they do (in this case we’re talking about formulation chemistry) you provide hands on insight that is helpful to someone. I found it useful in giving me a new approach to my at home creations and it even kindled my creativity because it gave me new ideas of how to craft something original. ~Thanks

  • Seeger 08/02/2011, 12:26 pm

    For the beginner, it is helpful.

  • critic 08/02/2011, 11:45 am

    I think the whole idea preposterous. Cosmetics is about innovation, and that is what people should learn: critical thinking, and then creative thinking.
    And I doubt one can learn cosmetic formulation on the internet; it requires patience, observation, curiosity, but not this kind of approach.
    I think there are already too many “knock-off” products on the market, many of the infringing patents, lacking claim substantiation data, safety data, but just out to make a buck by comparing ingredient listings, forgetting that the INCI names are, with few exceptions, much too vague to help truly identify the exact substance(s) used. this is particularly true for plant extracts which are just listed as the name of the plant, but give no indication of how the extract is obtained (water or solvent extraction, or other methods), how much of the “extract” (powder, hydroglycolic solution, essential oil) is really used; many biotech products and protein hydrolysates face the same characterization problem.
    This confusing situation certainly does nothing to make a better reputation for the cosmetic market!

    Training people is fine, and doing it for free is a debatable choice, but I don’t think this approach is the right one.

  • Susan 08/02/2011, 10:31 am

    I am a beginner in this area and thought the information was exceptional and very helpful. Thank you and I look forward to seeing more of your information and learning more!

  • M2T2 08/02/2011, 9:49 am

    It is insightful and contains rational approaches to comestic formulations. I am thankful for your contribution.

  • Jeffrey Ehlinger 08/02/2011, 9:41 am

    Over the years I have knocked off several National Brand Equivalent formulas that wound up as generic products at national pharmacy chains (lip balms, analgesic creams, etc.). Whenever I read articles about Cosmetic Chemistry, I like to think I’m modest enough to admit that I will ALWAYS learn something new and thats what I love about this job, I’m always learning! With regard to Perry Romanowski’s “How to Knock-Off a Cosmetic Formula” I learned several useful nuggets of knowledge to apply to my everyday work. I found the report to be systematic in its approach to cosmetic formula duplication and very comprehensive in its scope. Where was this useful tool 10 years ago when i was just starting out?! For the informative guide, thank you Perry!

  • dany 08/02/2011, 9:33 am

    “How to Knock off Any Cosmetic Product” is a quite informative and useful.
    Thank you.

  • Dr. Phyu 08/02/2011, 8:42 am

    Mr. Perry,
    Thankyou for sending me useful information.
    Actually, i am trying to produce face cream in the form of paste, based on herbal plants.
    Honestly speaking,i am searching for mould control technique for paste type.
    Currently, my product is stable in dry form,and practically can remove pimples,freckles and blackmoles. But difficult to use.
    Anyway, your information is beneficial to me and looking forward to your reply.
    Dr. Phyu


  • Raquel 08/02/2011, 8:42 am

    I thought that this was a great insight to what a cosmetic chemists thinks about when evaluating the competition’s products and rebutting with a new product. Very helpful for beginners.

  • Ernesto Leon 08/02/2011, 7:57 am

    The articles are very useful

  • carol 08/02/2011, 7:54 am

    Actually I thought this report was lame. Telling us to read the ingredient list isn’t really particularly helpful.

  • Susan 08/02/2011, 7:12 am

    Cosmetic chemistry was my third career. Most of this info I learned the hard way with a lot of time and effort. You have succeeded in producing a gem which should help out a lot of us out there who don’t have the benefit of a lot of expensive equipment. Thanks for spreading the wealth.

    • mary 01/19/2012, 9:49 am

    Hi Perry,
    Its very useful for new comer to the cosmetic industries.
    Thank you for making the effort and for sharing your knowledge. Keep up the good work.

  • RHR 08/02/2011, 6:53 am

    I enjoyed the content! I was thinking the approach was plenty sound!
    Glossed over the color / stability a bit, but that’s probably in the ‘book’!
    Formulating is a great art! and I think you touched on both the
    technical and personal fulfillment aspects of it. Thanks for the web leads!
    I Look fwd to more!
