    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.

    Dear Perry,
    First of all …Thanks for the fabulous ebook…I learned unofficially on how to duplicate cosmetics formulation during my early hands in R&D Lab. I NEVER know that there’s another systematics way to handle this crazy job until I found the ebook…

    Thank You so much Perry.. you are the man..

    Love from Malaysia

  • 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

    I read it and I love it. Thanks for publicate it. I have a little cosmetic formulating experience and it will help me a lot. It is comprehensive and logical. Thanks again!!

    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

  • Kathy Jurn 11/15/2014, 5:10 am

    I found your book regarding how to duplicate cosmetic formulas very interesting and informative. Now to get to work!

  • 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

    thanks for the information that you sent to me it is helpful and I’m looking forward to learning more

  • 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

  • Tobiah Belcher (PUSH products) 10/18/2014, 10:51 am

    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

    Very informative and helpful. Thanks so much.

  • Marisa 10/03/2014, 8:03 am

  • Tan 10/02/2014, 3:28 pm

    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,
    KJ

  • Judith 09/22/2014, 1:08 pm

  • Jose 07/28/2014, 10:57 am

    Hello,

    “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.

  • Paulette Brown 04/19/2014, 9:40 am

    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.

    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

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!

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.

    I am so glad to have come across your website. Thank you!

  • yaoyushan 01/08/2014, 6:36 pm

    Even though I am not native English speeker, but the book is vey useful, it is easy to read and understanding. Thank you for your wonderful work.

  • Sarah 01/06/2014, 9:25 pm

    I am a newbie and found this a very easy read considering it IS cosmetic chemistry. I especially appreciated the easy to follow steps that approached formulating logically such as the 1% line and others. Thank you!

  • kwan 01/06/2014, 9:06 am

    I am a very newby and I found out that this pdf is a very great start for the beginner. Easy to read, even if I’m not a native. Thanks again for this useful info :))

  • Lynnie 01/05/2014, 10:47 am

    Thanks for the PDF! Very well-presented and informative. I would love more info on how to identify the 1%line and you should also please fix the typo on heading 2. “becoming and expert”. Good job and thanks again!

  • 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

    The book is very useful for the beginners without any formulating experiences.

  • michelle 12/11/2013, 9:21 pm

    Thank you for the pdf! It’s very informative and I will give this further attention once I have a break from school. I would like to experiment and see how I do, based on the instructions given.

  • goumenaki 12/11/2013, 5:45 am

    it is a very usefull article,easy to understand even if english is not your mother language.although i am more interested in specific formulas and the exact way of making them.still a very good start

  • berenice 12/10/2013, 10:29 pm

    Very interesting and useful facts love it!

  • susan 12/08/2013, 9:41 pm

    Found it interesting and regard it as an introduction to cosmetic science. However I will be looking for more in depth material comprising of formulations, regulations, pitfalls, financial issues etc.

  • Niki Neophytou 12/06/2013, 6:59 am

    Well written and comprehensive!

  • Joanie 12/05/2013, 7:26 am

    This is amazing insider information. I’ve been a DIY hobbyist for many years and have gotten great pleasure from formulating, not to mention the money I’ve saved. 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!

  • Natasha 12/04/2013, 10:32 am

    easy to read guide, such a great help and fantastic insight. Thank you!

    i like also in the booklet that it is organized and follow serial ideas in steps
    also and a very important thing,is although i studied pharmacy and cosmetics diploma,but i still in need to be more practical and realistic.and that exactly what your booklet guide for,in a very simple,easy and economic way.
    iam sure iam in need to buy this valuable book very soon

    Dear Perry,
    the book is a knock out bomb-shell. Words cant explain. God bless you alot. Your gift is timeless

  • yazit nor 11/24/2013, 3:31 am

    I have read the note that you send me and feel like looking at a map on where to go about for a beginner with non cosmetic chemistry background.

  • Harish 11/23/2013, 9:59 am

    Hi Perry,

    The link in your e-mail to download the `Primer on Natural Cosmetic Formulations’ does not work for me. Coyld you please send me the correct link so that I can down load a copy.

    Thanks,

    Harish

    • Perry Romanowski 03/17/2014, 6:51 am

      Hello Harish,

      I’ve fixed it so it should work now.

  • Harish Kumar 11/20/2013, 3:13 pm

    Very interesting booklet. I am in the process of setting up a lab to make lotions and soaps for specialty use. This book has been very useful as a first step. I look forward to reading other publications from your site.

    Thanks

  • EMMANOUIL GOUNARIS 11/17/2013, 1:23 pm

    very usefull!!!!

  • 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,
    Shiva

  • 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.

    • Luree Ward 11/01/2013, 8:22 am

      This was a great and informative presentation! Very informative and to the point!

  • Ernescka Ferguson 10/30/2013, 7:24 pm

  • Jude 10/19/2013, 7:11 pm

    This book is so informative, I am glad to have come across you website, it has enlightened me as I am staring my own cosmetic line.

  • 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

    Hi
    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?

    Thanks.

  • 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.

    Ray Hauser

  • Lierni 10/07/2013, 6:26 am

  • 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

    Perry,
    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.

  • Simon Ojiefoh 10/04/2013, 10:34 am

    It was great. thank you for this site and forum, though i haven’t seen exactly what i am looking for in this website, i am happy i entered this site.

    Very informative, it will be helpful in future formulating

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

    Hi
    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

    Hi,

    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

    LouLou

  • 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

  • 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

  • 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

    Genius!!!

  • 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…………….

  • 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

    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

    Very usefull!

  • Mary Udoh 07/25/2013, 12:03 am

    i have just discovered my passion for cosmetics formulation and my quest for knowledge has helped me discover Chemist Corner. Though i am a beginner, i am learning a lot from chemist corner, and the 10-step system for knocking off any cosmetic formula is superb, it makes me eager to do more. Thanks Perry, i’m in love with this field.

  • tunde richard 07/24/2013, 8:26 am

    we have not experimented the formulation yet,but from the the ingredient afre all on point

  • Samorn 07/22/2013, 1:52 am

    I’m glad to have found your website , after reading Knock-Off a Cosmetic Formula
    making me smile and more smart, especially step 3 and 5, it’s a basic advantage.
    I didn’t get such ideas from others , it’s simple but works well.
    Thanks a lot.

  • 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!

      Regards,

      AndyH

  • 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!

  • 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,

      Regards,
      AndyH.

      • 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.

          Regards,

          AndyH

    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.

    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!

    Andy.

      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!

    Andy.

    i hope mini courses will be useful for all cosmochemists

  • Jessica 04/06/2013, 1:57 am

    Very resourceful. Gives you basic knowledge, but in depth.

  • Dr Binod 04/04/2013, 12:20 pm

    Dear Perry,
    In fact, it is very informative in understanding some secret things. But it will be much more useful if you mention few more range of examples and describe the technical terminologies. Anyway, I enjoyed it. Thank You n All The Best.

  • Joy Gee 04/03/2013, 4:13 pm

    Dear Perry,

    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

    Dear sir,
    I enjoyed reading it and found informative. I believe this short course should be deeply studied by those they are interested to take making cosmetic products as a hobby or more seriously as a business . I think adding few more examples will make reading this document more attractive and interesting.
    thanks a lot

    Hi Perry

    It does look great. I will try out some of the suggestions and see how it comes out. Whichever way it turns out I will have learnt something useful. Thanks

  • Given 03/31/2013, 12:57 pm

    Hello Perry, thanks a lot for that insightful report. I really enjoyed reading it. Even though i have not yet decided on whether to knock-off any existing products on the market, it still came in handy. It provided me with some fine points on analyzing ingredient list. thanks once again and more grease to your elbows.

  • Emma Warrener 03/25/2013, 4:59 pm

    I found this really interesting – as a herbalist I want to make natural body care cosmetics for people, I didn’t count on having to learn chemistry in order to do so as I need to complete a Product Information File on each product. I love the different avenues which my career takes me, I also enjoy science and making things so this is right up my alley.

  • Teresai 03/24/2013, 6:50 am

    Thank you Perry. The e-book was very useful. It was explaining terms in a simpler way that could be understood by beginners like me.

  • 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.

    Thank you .

  • Neusc 03/06/2013, 8:40 am

    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.

  • darwisa 03/05/2013, 9:44 am

  • Eric 03/03/2013, 3:09 pm

    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

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.

    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

    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!

  • 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.

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:

  • 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.

    Hello

    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.

  • Miguel 09/09/2012, 11:57 am

  • Mar 04/15/2012, 11:15 am

    Dear Mr. Perry :

    I am more than interested in becoming an established cosmetic chemist , formulator , and scientist .
    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 ,

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

  • Anna 04/10/2012, 7:44 pm

  • 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!

  • 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.

    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

  • 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.

    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

  • 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!

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.

  • 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.

    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!

    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.

  • 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!

  • 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.

    Hello.
    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.

    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

    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.

    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.

    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.
    Regards,
    Dr. Phyu

    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

      This was an interesting read. thanks for the information

  • venkatesan 08/02/2011, 7:12 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!

  • Sharon 08/02/2011, 6:35 am

    Yes, I feel that the book is a great tool to read if you are starting out . I will give a new formulator and idea and a model to go by. I feel that the book deserve a BIG + (PLUS).

  • France Davis II 08/02/2011, 6:27 am

    I thought the information was very useful. For someone who is newer to cosmetic formulation and wanting to make products that stand out, it is a good idea to first understand what makes other products on the market so unique (from a formulators point of view not just from commercial claims). I think this information only adds creativity to the formulation and development process.

  • Nirali 08/02/2011, 6:08 am

    I thought it was interesting.

  • Ged Harrison 08/02/2011, 5:51 am

    A well thought-out and comprehensible guide to duplicating a product which will be particularly useful to small manufacturers without a background in Chemistry. More of a problem for us, particularly those not US-based is sourcing the materials we need for dupeing.

  • Rita 08/02/2011, 5:16 am

    How to Knock off Any Cosmetic Product was a great starting point for anyone looking at formulating for the first time. It was a great read and quite informative.

  • Sandi 08/02/2011, 5:03 am

    I appreciated the honest, simple and practical approach to an often “cloudy” subject.
    Thanks for sharing your knowledge Perry!

  • Tan 08/02/2011, 4:26 am

    The method is practical & useful.

  • ibrahim 08/02/2011, 3:11 am

    Thank you this is not for me but i think it’s very good for a person who are interested in the cosmetics,
    i am a chemist i love formulating perfume .i have master degree in chemical engineering , One of my goals is to discover ingredients that are capable of catching perfumers’ and brands’ interest, while at the same time fulfilling health and safety criteria and the capacity for long-term supply. All of that within the context of reconciling producers and consumers
    Natural living has always suited me and the influences that are part of my life have evolved and strengthened with time. Even when I was little, I was always intrigued by nature, I believe that is what has driven and lead me to live the lifestyle which I enjoy so much today.
    Thank you for the good work

  • K GANESAN 08/02/2011, 3:02 am

    It was a good and has many useful information. For an expeienced person like me it was very refreshing .

    Hello
    The report was well written and informative. Thank you.

  • Justine 08/02/2011, 2:14 am

    I think this is the best and most educative way for beginning formulist to engage with products and to get the hang of formulating products.

  • gatot 08/02/2011, 2:06 am

    Thanks Perry,
    I enjoyed it very much.

  • Georges klein 08/02/2011, 1:41 am

    I think the article was very basic and orientated for those who are beginning in this nice profession of formulating Cosmetics.

  • Eliane Treadwell 08/02/2011, 1:20 am

    I thought this information was very helpful! I enjoyed it very much!

  • Tawnya 08/02/2011, 1:12 am

    Some useful tips. Thanks!

  • michela 08/02/2011, 1:04 am

    I think this report would be very helpful to me, not only to duplicate, but also to understand how to develop a new formula.

  • Shlomit 08/02/2011, 12:23 am

    Very informative for a beginner formulater. Orgenize well, clear and with lots of helpful directions.

  • Lavi David 08/01/2011, 11:32 pm

    I think the information was very helpful and very practical.
    Thank you.

  • KANWAR 08/01/2011, 11:20 pm

    Dear Sir/Madam
    This is great idea to develop the cosmetic formulation in duplicacy.Yes we can take guidence from the recipe printed on Wrappers and can be helpful.
    Yes i will try to develop the same.

  • Christine Tritz 08/01/2011, 10:51 pm

    Hello,
    I am not trying to duplicate cosmetics, so this was not any use to me. But I did read it and it was interesting.
    Chrisitne.

  • Marilyn Chan 08/01/2011, 10:50 pm

    A concise reference on “How to Knock off Any Cosmetic Product” as the report is aptly titled. Thank you for making the effort and for sharing your knowledge. Keep up the good work.

  • Moni 08/01/2011, 10:30 pm

    Thank you for resending the publication. I think it is a good basic procedure for “knocking off” a product. I appreciated the effort and hope more of these come in the future.

  • Eric Revere 08/01/2011, 10:11 pm

    This report is a good primer for chemists with little cosmetic formulating experience. It is rudimentary, comprehensive and mirrors the logical approach that I have been successfully using for years.

  • dm 08/01/2011, 9:44 pm

    helpful but nothing earth-shattering.

  • alex 08/01/2011, 9:28 pm

    I Thought the “How to Knock off Any Cosmetic Product” report was quite informative and useful for those not so familiar with cosmetic formulations. For those of us who have been around for a long time it was refreshing to see that
    there is an honest and informed approach to such matters in this current world of misinformation.
