Perry, 44


  1. Blandine

    Nicely presented subject. Thanks

  2. Charlie

    Great overview on the steps needed to make a formula.

  3. Ruwan Tharanga Withana

    Its very useful to me.. Good work. I have one quotation, That sodium laureth sulfate is prohibitad in europe? Anyway I will always touch with your link. Thank you verymuch for giving this valuable opportunity.

    1. Perry Romanowski

      No, Sodium Laureth Sulfate is not prohibited in Europe.

  4. PY

    Hi Perry,
    The book is very well done: simplified approach, easy read and very practical. Thanks.

  5. Silva

    The book is very helpful. It helped me gain insight into the different cosmetics ingredients and how the work. This was absolutely what I needed. Thanks a lot

  6. Zahid mahmood

    It is my passion to work in cosmetic and skin care product. You have rightly diagnosed that I should take the introductory classes. It will be great to learn. Thanks a lot.

  7. Shannon

    As a budding cosmetic formulator, I appreciate a better understanding of how to achieve certain qualities in product and like the logical approach.

  8. naim

    It is really helpful, I have even adopted some of the steps outlined. But for someone like me living in a local community will find it difficult to conduct some of the analysis and tests put in the report. So I’m suggesting even though the report is quite informative that in future a home based analysis and test should be included to enable those who may found it difficult to access standard laboratories conduct their own at home without using sophisticated equipment.

  9. Azizur Rahman

    Hi ,
    I gone through this book several times and took notes . Though I am an Organic Chemist but I had no experience to make a formulation . This booklet is very very helpfull to me to coppy a product of a world class company , also given clues and other formulary resources provided by this book .
    Now I am trying to formulate few personal care products using least ingredients to minimize hypersensitivity . Ths booklet , along with your lecture give me guide line and resources to do this . Thanks a lot .

  10. Niel Robert Lim

    The course is “BS-free” and you get to learn things that you typically do not learn in a classroom setting. It is short and direct to the point. I definitely recommend this book to anyone out here learning the basics of cosmetics.

  11. loobyloo

    The information was very interesting. It gave insight into how you could learn to really understand putting a formula together, rather than following a formula to produce a product by working backwards.

  12. Sonya

    I have been getting my bottle out ,it’s great

  13. HÜLYA ÖS

    Hi Perry

    I’m a chemistry teacher from Turkey. I am giving a course to students high level chemistry (IBDP Programme). Also I am studying on producing some cosmetic products. Actually I am begining of it but because of my chemistry knowledge I am so excited about it. Thank you for your interest.

  14. Smrty

    Very informative for new formulation chemist like myself.

  15. Sonya

    Great reading thanks

  16. Heather Morse

    This tool was very useful and filled with step-by-step instructions.

  17. Laura Gutierrez

    I read about the different water used in cosmetics. Excelent short definition, straight to the point. It very useful in my case, because I’m developing an organic eye cream.

  18. Jennifer Hiatt

    I really enjoyed the information on duplicating formulas. Some of this I already to, such as plugging ingredients into a spreadsheet and figuring out the 1% line, mostly just for fun brain exercises. I didn’t think about the patent office before though, and there was other very useful information on the steps to take. This is making me want to take the cosmetic chemistry course, as I have a love for creating products and enjoy the scientific “non-pinterst” approach. Thank you!

  19. Gaylene

    Interesting information. Lots of work for sure!

  20. Kasun

    Very great.I am happy with that knowledge.I am with cosmetic science.I waiting for the free course.thank you.

  21. AL

    Hello , thank you so much for the information you offered .it was really very useful and practical.

  22. Max

    Hello 🙂
    It is a very informative document. I will have to read it again to pin some details.
    Really like it, simple, precise. Thanks a LOT

  23. Geeta Y

    Nice and helpful

  24. V.K. Varshney

    Read the book. Found it very interesting and useful for cloning of the cosmetics products. Shall be applying the approach in identifying the gaps and making innovative cosmetics products. Will also extend this understanding in creating fragrances for aroma sticks, candles and diffusers.

  25. EJ

    Great insight and overview of the cosmetic formulation process.

  26. Marija

    Thank you very much, I have been thinking about the principles from your report for years, now I found somebody wrote them down in a logical sequence

    1. Olga

      Good materials for these who just started.

  27. Daniel Bernier

    This is a good overview of the development process.

  28. Hedy

    thank you so much. I find it so helpful and you make it easy to understand. Looking forward to learning more from you.

    many thanks

    Kind regards


  29. Carol Cabrera

    Basic and straight forward, as it should be. For someone starting is quit usefull.

  30. janet piller

    Tkank you so much ,you are one in a milion.

  31. Michelle

    Concise and easy to understand. I’ve started work on my first project!

  32. Anita

    To be honest, the book is definitely beyond my capability in chemistry at first glance – I was looking for some information for my super brief assessment which is a combination of a research paper and something else. Even though I finally give up on using the content for this paper… It really opens up a new area of interest for me:) The pdf is really comprehensive .

  33. Richard

    As a beginner I found the information answered my questions I had been pondering on. Thanks.

  34. Sarah

    Very informative!

  35. Ionas Anastasia

    Great material!

  36. Stacy Lee

    I had read your little book and got some new thinking for my business. It’s a basic conception of cosmetics but easy and simple to understand. Thank you very much for help.

  37. Cynthia

    A logical approach to recreating a cosmetic product and definitely appreciated. It’s very hard to find reliable scientific cosmetic science information, that this document is much appreciated. It is however very much an outline of what to do. The core information you would need to replicate a product relies on you knowing how to create one in the first place, and would have to be learned elsewhere. With regards to the content, I think the first section on how to obtain product samples (of the item you wish to clone) might be a bit outdated, as it doesn’t seem that hard now a days to obtain samples, unless the document is referring to closed samples and not a large container of the product itself. It would have also been nice to see a list of the tests one could perform on a sample and what parameters they are revealing about the product. For amateur cosmetic scientists that would not choose to obtain these tests, it would be helpful to suggest simple tests that could be done at home or some useful qualitative tests that could yield some actionable results.

  38. Paola

    Thanks for the great info! Grazie mille! 🙂

  39. Victory Chiedozie

    Thanks for the work you do for people for people like me. I’m looking forward to the mini course. Thanks again

  40. SAID nadji

    very interesting

  41. Hasibah Sandifer

    I want to know after I figure out the formula. I will need a manufacturer. What other services do the chemist corner do? The “How to Knock of the Cosmetic Product is great!

  42. SAID nadji

    I am getting good knowledge from the website chemistcorner, related to cosmetics and formulation, i am willing to go further, and maybe i will undertake the course, i am having to open a business in cosmetics, and i hope i enhance my skills

  43. Katarína Hrivnakova

    Some useful tips. Thanks!

  44. Christina

    Thank you, this was helpful and informative for a beginner. I appreciate the knowledge.

  46. Sou

    Great booklet with useful introductory info. Thanks for sharing it with us.

  47. Jacky van Driel

    I found the guide extremely helpful, I like how it takes the reader through all the necessary steps (zooming in from seeing the forest to the individual trees). It
    has the basics that I needed. Thank you.

  48. Vanessa

    Great and practical step by step guide! Very helpful. Thanks

  49. Daniel

    It would be nice and useful to get some easy but verifies formulas for small-factory capabilities willing to manufacture EDT and EDP. Thanks!

  50. francesca

    Really interesting and helpful. I definitely want to listen more! Thanks

  51. Charlotte

    Thanks for offering me such a helpful course. I am looking forward to it!

  56. Sílvia Fardilha

    amazing reading

  57. Jane

    I found this piece helpful and insightful

  58. Todd Ziegler

  65. Felicia

    Perry, I found this report to be very informative and helpful. I am going to use this to help create a moisturizer. I have a specific skin issue which current moisturizers do not help.

  66. Peter Lwegasira

    The report is excellent and has helped me a lot as a starting point for my career in cosmetics formulation

  67. Tatiana

    Thanks a lot for this report. For me, a chemist who only dreams to become cosmetic chemist, it was very useful and helpful. Intresting and easy described, it gave me a spur to keep moving in this direction and learn more.

  68. Gregory

    Thanks for that ebook, Perry!

  69. Bri

    I found the paper helpful and informative. Ironically enough, I found myself already taking similar steps when asked to recreate a pomade for a friend. This paper gives me solid guidelines to follow.

  70. nounnou

    Thank you for all! I really want the free mini course in cosmetics also please ^^

  71. Jona

    May god bless you!!! Thanks a lot,it was very very helpful.

  72. Aury

  73. Sara Brown

    Very interesting read

  74. Gordana

    Hello! For the begginer in
    making cosmetic formulas this is useful tool and guide how to learn new things!

  75. Ari Psaltis.

    Asked Perry a few questions.

  79. Raquel

    Very much happy with your free report. It gives so much info that provides guidance on cosmetics and formulating. Thank you!

  80. Ravindra Bhise

    Dear Mr. Perry,
    I retired as General Manager QC from a well known pharmaceutical company of India. I formulate a few varieties of shampoos.
    i have gone through “How to Knock off Any Cosmetic Product”. I liked it. It is very much informative and it feast to go through it.
    It is simply fabulous.

    I will be happy to receive formula of Hair dye shampoo, which will turn hair black after using it. The hair dye shampoo should be stable for atleast for one year from the date of preparation, it should be non allergic to scalp / skin and should not damage hair.

    Your immense and prompt help is highly solicited.

    Thanking you in anticipation.

    Warm regards.

    Ravindra Bhise.

  81. sakinah

    The best reference ever

  82. Anthonia

    Exactly what I was looking for. I have much clearer direction now.

  83. Nora

    The report was obviously very informative but more so very important as information like this isn’t easy to find or even available on the internet (that I know of). I think this report also has given me hope and excitement for the future as I know more to want to educate myself and soon get a job in this industry.

  84. Chitra

    How to Knock off Any Cosmetic Product is good for beginners as it’s simple and easy to understand.

  85. Yogesh Patil

    Very useful in formulation of new cosmetic products,also I really understood the use of ingredients in formulations.Thank you perry.

  86. Eamonn

    The report was very helpful and easy to read. It is a great starting off point

  87. Tim

    This report is a good read for those just starting out.

  88. Tendai

    the report was very helpful as i am new to the cosnetics industry but will very much love to be acquainted with the industry. i learnt a lot and hope to implement the steps. if i bump into any problem. i will contact you.

  89. dire

    has very good information, for me that im starting out on getting to know the beauty industry from a future posible formulator of my own products it helps alot thank you!

  90. Taubah Salim

    Hai Perry,
    Thx for your information in your many videos… I want to create a bussiness natural soap and shampoo In my country Indonesia… I hope I can join in your natural cosmetic course….

  91. Olesya

    It was a very helpful guide for the beginner. I learnt some new info but I would love it to be more specific and more informative! Of course I realize it is a free guide so we can not ask for more. Thanks a lot for sharing this information and helping people to start off.

  92. Nataša

    Very nicely given instructions, very precise! Excelent instructions! But my biggest concern is with all the experience that you need (especially in the field of analytical chemistry); also to be able to get water content and other measurements (given by different analytical methods, like GC…) you should really be in touch with a professional lab. I also pose a question here: I primarily want to formulate my own cosmetic product simply due the fact that none of the products on the market fit my needs, therefore I don`t want to replicate something that is already out here; also It`s very unethical for me to work like this, even though we know how the world works today…

    1. Perry Romanowski

      The point of replicating something out there is to learn how to make the product. It’s not meant for you to go out and start selling someone else’s formula. Once you know how to make a product, you are supposed to modify it to make it your own.

  93. Ahmed Alabboud

    its very good book for beginner cosmetic chemists include valuable information about how to start putting formulation besides to guidelines for improving your skills and some good links for websites and books which are useful for any cosmetic chemist.

  94. Mohammad Tarique

    It is very interesting and knowledge full, it provides a detailed information about the modification in formulation, the content is good enough for a chemist who want to start new formulation. Thanks perry for the information

  95. V

    I really appreciate your effort and would like to know more about the safety part which is ignored by most of the DIYer.

  96. Jeremy Maher

    I thought the report was great! A good starting point that helps you ask more intelligent questions about the process.

  97. ashley anderson

    good break down on the processes of cosmetics. I enjoyed hearing that creating a new revolutionary recipe is not the objective and that most companies are just trying to do what their competitor does better. I’ve always know its more in marketing and your brand but this just helps solidify that information.

  98. Dean

    Very informative

  99. Miltos

    Enjoyable and well rounded . A great book to get you started with the basic components .

  100. ellie kim

    How to Knock off Any Cosmetic Product report was very helpful and informative for those who are entering the cosmetic science formulating program or industry. I got to know new things and helped me to have kind of ideas of how cosmetics are formulated.

  101. Troy Purvis

    Perry is pretty knowledgable about the industry and accurate in describing the industrial practices. I came from working in Pharma for 15+ years to cosmetics and I am quite frankly shocked at what the cosmetics industry gets away with in terms of regulatory, but I understand FDA’s priorities are Big Biopharm and not necessarily cosmetics. You get a degree of freedom and creativity in cosmetics which i enjoy.

  102. Ijeoma

    It was very helpful
    I anticipate more

  103. Amaka

    Very informative and helpful!

  104. Melissa

    Very useful information. Helped me to know I am already on the right path.

  105. Lil

    Very helpful to beginners like me. Pls Perry, can you email me the downloadable spreadsheet you created on expressing formulae in percentages? My email is Njokulilian18@gmail.com
    Thank you.

      1. Lil

        Thanks Perry, I have come across that video before now, great video it is. But I couldn’t download it so I could easily edit it with my own figures. Pls how can I make that possible. Thanks for your good works always

  106. Shera

    I read the “How to Knock Off Any Cosmetic Product” report and I basically like it. It is a very fundamental report on how to duplicate cosmetic products but certainly useful for anyone who is interested in going into the cosmetic business or formulation. It helps me understand the basic procedures used in decoding the cosmetic products.

  107. Janaki

    It was really informative and well explained .

  108. Kelly

    Insightful and interesting with a touch of naughty – formulating a natural skincare product is not easy so the tips are great. I am working hard to find the right bio-active ingredients to create an amazing product using live cultures. Challenging to say the least. Keep on posting videos on formulation!!

  109. Pat

    Contains a lot of good information. If you don’t already habitually read the ingredients of products you buy, now you will start.
    Perhaps I expected more discussion of emulsions.

  110. Shweta Naik

    Yes it was useful. Now I know what is in my product.

  111. Apple

    Very orgnized guidelines and tips especially for beginners thanks alot for the info

  112. Soba

    Thanks again, Perry, I couldn’t hell but comment twice, worth the read.

  113. Soba

    Wow! Super interesting, I’m glad I made out time to read it, thanks so much Perry.

  114. Georgia Pelteki

    There were definitely a lot of things I never thought of. Thank you for sharing this information.

  115. Mihkel Mariusz Jezierski

    I am about to start my own haircare line as a school project and I am really-really glad that I found your website. I appreciate the effort you put into it and I am hoping to achieve great results with your members help!

  116. Evelina

    Duplicating good examples is good beginning and practice. Liked the article pretty much!

  117. Alvaro

    It was a good hint to start. I already used your suggestions to sift through the internet. Now, for me, it’s like a new window is opening in front of my sight. It’s now a pretty exciting endeavor.

  118. Mao HENG

    I want to say Good Job. I am really interested in your course, but I don’t have any knowledge about cosmetic subject because I never learn it. It means that I am really a beginner. I am Mao HENG and from Cambodia; I am interested in cosmetic industry and want to create a cosmetic line and own products supplying in my country(Cambodia).

  119. SDC

    I have just started formulating, found this very interesting!

  120. Jason

    This is a great way to getting your feet wet in formulating your own line of products.

  121. Angelina

    Is fantastic website and teaching method, I want buy your course. I’m a l’Orèal Paris member in Italy and I want a best career for me. Thank you Perry.

  122. Tosin

    Fantastic report. I can’t wait for the free videos I know it give me deep insight

  123. Taina

    Not knowing much about the composition of cosmetics, “How to Knock off Any Cosmetic Product” was very enlightening. The basic recipes were interesting to read. Thanks!

  124. Justine

    Great, step by step approach.

  125. Nadia

    Thank you for the free report on duplicating cosmetic formulas. I found it to be a validation that my processes have been correct thus far. I have been attempting to eliminate less than desirable chemicals from cosmetic formulas and replace them with oils, waxes, and plant derived ingredients. I spend a good amount of time reading labels, looking up the functions of ingredients that are unfamiliar to me, and researching ingredients that are more desirable. Preservatives are really bogging me down as I am not sure that the natural replacements are entirely effective and have now become aware that their use is also formula dependent so a little more complex than I initially realized. I would love to find a cost effective way to have my samples tested. I’ll post on the blog!

  126. Christina

    Interesting so far! It’s definitely not easy (especially for someone who’s not majored in chemistry) but a great way to start. Thank you!!

  127. Malia Kanakanui

    The information was SUPER informative. Thanks again Perry for everything you do. I appreciate this website and your Beauty Brains Podcast. Keep up the good work!

  128. Israa

    I found this report very useful. It was a good start for me, it helped me to understand the cosmetic product formulated and give me steps to make my own.
    Thanks Perry

  129. Fatima

    Thank you very much for the superb teaching


    This great! You are good man..
    Everything you have written about cosmetics is educational .. thanks so much

  131. Zorai Houari

  132. Hitendra

    It was wonderful information,I really appreciate your work.

  133. Smk

    Thanks a lot for your free copy of a very valuable book.
    Knew certain things but dint know how to proceed but your book helped me know them better and carry things out in a proper way. There was so much of useful information. Would appreciate if more of such info is shared. Thanks again 🙂

  134. Walter

    some more detail on the make-up of the base cream would be ideal. The small ingredients, that are technically “some” or “trace” amounts, while useful/potent/required in those concentrations need to be carried by a base cream/lotion. The weighted formula for such a cream/lotion and the variations of their formulas to achieve different results would be an ideal jumping off point.

  135. Andrea Guardalbem

    Hello Perry, I really enjoyed it and it’s being important because I’ve been out of the market for many years and it’s a way for me to go back to school and remember a lot.

  136. Michelle Bahera

    Really enjoyed this book.gain some really good knowledge.

  137. Nontethelelo

    Report is so useful. I am lookinf forward to create my own.

  139. Stacey MacDonald

    I read this report and thought it was very insightful, can’t wait to get started!

  140. Anuradha

    Lovely guide to formulating but since I’m self taught kitchen chemist it will take me a while to formulate knock offs, it was a great read though

  141. Bernie

    Great report with lots of info!

  142. Alma

    This will help everyone who are interested to learn about this field as well as giving us new ideas and insight on how we can make or do the right things that we can learn from this course. Kudos to the people behind this site ..thank you

    It was perfect. I do appreciate it.

  149. Esther

    Great insight!

  150. Esther

    Gave great insight on not trying to reinvent the wheel. It was also great for someone testing their formulation skills to gain confidence through this process

  151. SG

    Interesting concept of duplicating commercially available products. Simplified steps that can be understood by folks with no experience in this field.

  152. Gil

    although im not a fluent writer in english i understand
    it perfectly ,and perry explanations are simple and professional in this short yet
    comprehensive book i am happy i got a chance to read it and understand better

  153. Aerin

    “How to Duplicate a Cosmetic Product” is simply excellent!

    As for me, definitely not to copy exactly the same ingredients, but to improve it. Add some ingredients that useful. Tweaking is the word.

    Awesome love it!

  154. Elgato

    The report was very useful specially for beginners formulators. It contains all the basics informations that u need to know

  156. Triantafillidis Kostas

    I thing is helpful

  157. Tien/ Ann

    By reading the report I know more about cosmetic and each ingredient categories. I’m not a chemist but I’m be able to understand the report and I learnt a lot about cosmetic and how each formula created. Thank you.


    This was the information I was looking for. I sold expensive anti-aging products in the past, and finally became curious about what was in them. I realized with a little knowledge, I could create great products for myself… and my board members. This really helped!

  159. Maya

    Very interesting. This supplies another perspective working from the bottom up.

  160. Dr Pesko-Tsakoumaki Natasa

  168. Holly

    Thank-you so much for the information on ,”How To Knock Off a Cosmetic Formula”. Having the steps mapped out should be most helpful and interesting!

  169. Safieh

    This mini course was an eye opener to why it is important to see how other people in the cosmetic industry make their products. This strategy can guide people who intend to inter the cosmetic industry in the right direction. Adopting such practice may help save time, money, and provide crucial knowledge that is needed to make a product standout from so many others on the market.

    Great information! I already started with my excel sheet to begin with my creation of cosmetics. Thanks!

  171. Ross

    Hi Perry.
    How to Knock off Any Cosmetic Product
    report is very helpful. Recently, I was giving a task to make no tear baby shampoo. I followed your guideline and it’s work. I also tried to myself and I satisfied with what I did. Tqvm.

  172. Ivan Senteza

    Quite helpful.
    Keep it up please.

  173. Sofia Paculan

    I thought that this was a very informational and interesting report. I’m more than happy to learn more!

  174. Laura

    Thank you for sharing your article on How to Knock-Off a Cosmetic Formula. It was very informative for a new formulator such as myself. I look forward to reading more of your work.

  175. Jahaira

    I think it’s excellent. Very helpful!

  176. Promise

    Wonderful insight on how to knock out a cosmetic brand.
    The outlined steps are very practicable.

    I would want to know if one can get quantitative result of all ingredients on analysis.

  177. Jay Okose

    I truly enjoyed reading the articarticle. Learning that coping known brand will give me an edge in the market place is good New. Testing and analysis is also helpful. Overall going through your training will help in creating standard brand. Thanks.

  178. Margarita

    This is a very helpful procedure written in a clear, scientific manner. I do think the section on searching the patent literature could be expanded, perhaps with an example.

  179. Preservando Dagdag

    I find the report very useful especially in my research & development work.

  180. Inder

    Very good primer for understanding the basics of cosmetic formulation, thank you!

    I wanna say thank you for this very very informative topic,its a great help as an additional knowledge about cosmetics and I want to learn more about formulation!

  187. J.J.

    Brilliant, brilliant, brilliant little course. Clear, concise and filled to overflowing with great information.

  188. Georges Selvais

    Very interesting.It is easy to understand yet I learned a lot. If we ever need to duplicate a formulation this 10-step process would save us a lot of time.

  189. Dan

    This was a good high-level overview of reproducing a cosmetic formula. There were a couple examples for staring points. If you write a new version, I suggest adding a flow diagram of the process with call outs with a real-life example. Take an on market product, but not use it’s name, and walk through the break down, the reformulation steps and the final comparison with analytical data demonstrating the similarity between the original formula and the copy.

    1. Perry Romanowski

      Thanks for the tips!

  190. Tatiana

    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.

  191. Jenya

    Thank you, I have found it very helpful. At the end of the report you provide some link to the “Beginning Cosmetic Chemistry 3rd Edition” book, which is very expensive. my question is if I should consider to buy second edition of this textbook, or it complete waste of money?

  192. Emma

    Great report with very useful information. Thank you.

  193. Yuly

    Very help full for my study……thanks

    It was very helpful for me, so I will be glad to get even more information about cosmetic formulation. the report contains link to the textbook : Beginning Cosmetic Chemistry 3rd Edition, which is very expensive one. my question is if second edition may be helpful as well or it is just a waste of money? thank you!

    1. Perry Romanowski

      Yes, the second edition of the book would be helpful.

  196. Angelica

    Thank you for a very informative report. To develop cosmetic formulation is my interest. Will keep in touch soon.

    I think that is a good start point. It has good informatio. Is a good guideline, but also think that needs more about legislation. Thanks

  205. Emma FitzGerald

    Thanks for the book Perry. I found it easy to read, with a lot of helpful information. As a Biologist with only a little experience in Chemistry it is a really good starting point for recreating some of my favourite products. I’ll be putting your process into action very soon. Thank You!

  206. Frieda

    It is very useful and mind opening. Thank you!!

  207. Kathryn Mullins

    Good overview and resource recommendations. Quick and easy to review.

    Like how you explained finding the 1% line. Now my problem is just finding the right equipment to blend them on a larger scale.

  215. Anthony Gary

    Very good program and will be joining other chemist.

  216. Nick Dalton

    Hi Perry,

    It looks very good.

    Especially the BOMS/recipes.

    My biggest challenge will be sourcing the Raw Materials and what equipment to start with.

  222. Emma Dsa

    Very informative… I wud like to know about paraben free cosmetics with safe preservatives.

  223. Alfred

    Hi Perry,
    I am located in Burundi and hold a bachelor’s degree in chemistry. I only have 3 months in a cosmetics industry as quality controller. Am I eligible to follow the cosmetic course from your website and have all documents related to cosmetic science and formulation?
    My former carrier was in the brewing field. This will empower me in the cosmetic company.

    1. Perry Romanowski

      Yes, you can take the cosmetic science course.

  224. Naimat ullah

  227. Charles

    found the report very useful and am reading it over again to really get foll meaning of everything.

  228. Kathy Holman

    Such a lot of excellent information. Too much to absorb at one time. A fabulous reference for making lotions and creams.

  229. M N Hawkins

    As someone who will be doing this as an amateur, I found the pamphlet pretty easy to understand and follow. I had no idea where to start, but after reading this, I’m feeling ambitious , hahaha.

  230. John

    Drugstore.com and Beauty.com have closed as of Sept 30th. I read much of the PDF and found it interesting reading. Really, all I want is an answer to two simple questions. First, why does new “Old Spice ” aftershave smell different than the original stuff in the glass bottles, and, two – What chemical makes Gillette Hydrating body wash so slippery? I have used it as a pre-shave and it’s very effective. Thank you for a very informative article.

    1. Perry Romanowski

      Old Spice smells different because they changed the fragrance. I don’t know what the ingredient list of Gillette body wash is so I can’t tell you. Most likely a silicone like Dimethicone or Cyclomethicone.

  231. Dr. Omji POrwal

    It really very informative, design by properly through experienced research people, very helpful for new people in cosmetics.

  232. Slobodanka

    The presentation can be useful for beginner as well as colleague who is involved in this material a long time. Congratulation!

  233. Florence

    Educative and very interesting.
    Reading it made me realize many things and also thought me many things.

  234. Tony

    For once, a pamphlet that makes a sensational claim on the cover, and backs it up in the text! Its advice was clear and concise, and I’ll be referring back to it.

  235. Thao Pham

    Hi Mr Perry,
    I’ve read How to Knock off Any Cosmetic Product yet, and I find there something interesting to learn. Acttually, I used to find the way to make a product like this, but I didn’t have to check a sample (cause it isn’t easy for me to buy a sample). I just saw the ingredients and tried to do like them. It wasted a lot of time and material. Now, thank to you, I know how to do this step to step, and I really appreciate that, thanks a lot. And I’ll try to learn more and more.
    My English isn’t well so I hope you can understand what I’m saying and please sympathize with me!
    Thank you and have a nice day!

  236. Dr Francois Robinson

    The content was awesome! Thank you.

  237. Siddhant

    Useful information , but how to formulate new products handbook would have been more useful, full courses are very costly , students cannot afford , but thanks for the information

Thank you again and look forward to learning more from Chemistscorner!

  252. Julie

    This ebook was really helpful with learning how to duplicate any product. The only thing I had trouble with was Finding patents like the book suggested. I would recommend adding more information on how to find patents for your favorite products. I don’t know if many companies file patents for products anymore, I was finding more patents on research and how specific ingredients work together.

  253. Shaliza

    The document provides a good general guideline for duplicating cosmetic formulations. It is important however to understand the function of each ingredient in the formula before eliminating ingredients from the formula.
    I analyzed a product containing 41 ingredients and observed that orange peel oil and limonene were listed separately. Is this an example of “ingredient fluff?”

    1. Perry Romanowski

      No. Limonene must be listed because it is a known allergen. Otherwise it wouldn’t be listed because it is part of the fragrance.

  254. Jamie Saphow

    Although I have some experience formulating, I’ve never really done it for the category that I now find myself working in. This was an extremely helpful guide to even some rudimentary ideas that I hadn’t seen before. Much appreciated that this was offered for free and that it had quite a good bunch of information in there.

  255. Vampiris

    I would like to start making my own cosmetics and this publication seems to be helpful. I have not started reading it yet but soon will.

  256. Mano Appapillai

    Great start on cosmetics industry/chemistry . . . just the basics !

  259. Jo

    Found the report very useful and can not wait to give it a go. Looking at a few key areas I now know where I have been going wrong as I have been trying to copy a few other products. This report will help we get the products bang on!! Thanks 🙂

  260. Haneen faqih

    Hello ,
    Thank you so much for reply .am ready to get all the information and to learn from it .

  261. Ciara

    A very thorough and interesting report. I am relatively new to cosmetic science and am looking forward to experimenting! The report was very informative and easy to follow, unlike others I have read.. not intending to be a ‘knock off Guru’! But looking forward to trying out some recipes..
    Thanks Perry!

  262. Shawnalee

    I want to say a big thank you to Perry for taking this initiative! Organizing a forum that aids prospective cosmetic chemists and creating a synopsis of what cosmetic chemistry entails, I can definitely use this forum as a guide to point me in the direction that I see myself in the near future.

  263. JCM

    I loved!. I think it has very clear information and resources for those who want to venture into the production of cosmetics.

  264. theo

    Excellent! It will be very helpfull!

  272. marjan

    good for the first steps in cosmetics

  273. Noe

    As a newbie, considering a carrier shift into Cosmetic Formulation, I found it very informative, giving me an insight into some of the aspects of formulation in easy to understand language, and providing great links for further research.

  274. Pervaiz Iqbal

    Very useful publication from cosmetic science

  275. S Rashidi

    Thanks a million, very handful

  276. Gina

  279. rudaina sumrein

    It was quite a nice introduction to the beginner.Lines out all the basics so you can go to the next level.

  280. Mary

    Was really helpful… Thank you

  281. Cynthia

    Thanks so much on providing great information with a scientific basis, not just affirmation and assertions. It truly makes a difference. Science helps formulating work better.

  286. Christine Davis

    I really enjoyed reading the information on how to duplicate a recipe. It was very informative and understandable. I enjoyed reading, can’t wait for more to come!!

  287. Rashmi Saxena Pal

    Perhaps the efforts to add the constituents in a ratio so as to increase the shelf life of the product is very important.

  288. Rashmi Saxena Pal

    This will be very helpful to know about the feasibility and compatibility of the herbal constituents.

  289. Umesh Kanade

    It was very useful information to me,but initially I am interested to know about the specifications and method of analysis for the cosmetics products like Lotions,Shampoo,Shampoo with conditioner,Face wash,Body wash,Hand wash,Dish wash,Surface cleaner,After shave lotion etc as per legal requirement in India.

  290. Han-Chun

    Very informative!

  291. Carolina

    Thank you for the report, it is so useful, I always read all the ingredients of the products. The advices that you give, about the order list of the ingredients, look for patents, design of experiments protocol and tests, makes it clearer to understand how the chemistry of cosmetics works. However, I have a question: Does it work for natural cosmetics? Thank you in advance.

  292. Diksha

    Thank you so much for report its very useful and helped me alot.

  293. Kimi

    Thanks ,very interesting

  294. Cheri Bowen

    Thank you so much for your help! I really love this information. I only wish I was more smart to figure out things a little better. I appreciate you guys for making this.

  295. julio adrian tzoni patlani

    thank you so much for the information, it is really useful definitely. However, it would be great if you can share information about normativity or standardized testing methods for stability.

    1. Perry Romanowski

      Search our website. We have an article about stability testing.

  296. Howie le

    I find it very useful. I am new to the cosmetic formulation industry. I came from a coating background both as technical (formulation and Rnd) and Sales. I have been curious about the cosmetic formulation. This report was very helpful because it give me guideline where to begin. I would recommend it to anyone whom just start out in the cosmetic industry.

  297. Shonnie

    The information was very useful and timely. Will definitely keep those tips in mind.

  298. Juliia Miliar

    Thank you for this course. This is good information for starting in general.I think it’s good for people who are just beginning to be interested in making of cosmetics. In any case, thanks for creating and sharing!

  299. Naomi

    Thank you for giving this information freely. It has helped me so much!

  303. Betty

    Thank you very much, Perry. Great course. You are a wonderful person.

  304. Maria

    That was lovely, thank you so much. Much more interesting and informative than I expected.

  305. Diane M Taylor

    Thank you for the report. It was a thorough article for those interested in copy. My interest is in not being copied. I am launching a skin care line where the solvent is probiotic turmeric from fermentations- formulated into serums etc. From what has been suggested, I do not think that the process could be uncovered , unless fermentations of other types were substituted. My other interest is in producing formulas that are completely natural with trusted ingredients that create a clean label. Any suggestions? I see many formulas on your website that I am interested in for customers that want the probiotic fermentations with the serum feel they are accustomed to. Penetration may be compromised, but consumers associate feel with quality.

  306. Ali zaidi

    Ofcourse i’ve studied the report but i’ve a question. Most of the companies and brands don’t mention the orignal chemicles used in product and fake the chemicles to minimize the risk of copy can you explain how to get rid of it ?

    1. Perry Romanowski

      Most companies do not do this. At least in the US. I don’t know how you can solve that problem.

  307. Tarra Swenson

    Hi. I am a for what it feels like, a rapidly aging woman that cannot afford the beauty creams that are out there. I googled like crazy looking for a way I could get ahold of the ingredients. I found a site that lead me from one site to another. Yours seems so much more promising than others and gives me a chance to afford the concoctions I could only dream of having. I splurged on a skincueticals hyurlonic and ferulic serum that I loved so much but cannot possibly afford. So I am glad I found you. Now I’ve just got to figure out how to mix and store these magical serums I am also planning on gifting my sister’s with them too after I get the mixture down right. Then they’ll want more hence you’ve got a few more customers! I’m excited but nervous because I hope I can get it right. I am grateful of your help!

  308. Bukola

    Thanks very much for creating such a valuable report, i belief that i can duplicate any cosmetic product now, I would be more grateful if you give more valuable information on how to become a creative cosmetic formulator. Thanks

  309. Larry Denton

    Thanks for the tutorial on how to get started in the cosmetic area. Spent many years formulating drugs but have switched to cosmetics in retirement (semi-retirement?). It might be helpful if you did mention that some kind of microbial testing on your products might be needed.

  310. Wala elfatih

    Very impressive overview i enjoyed reading it thank you

  311. nasim

    thank you for it, i use its steps

  313. Naomi

    I really enjoyed reading it. For someone who is just getting into cosmetic chemistry it was very helpful and easy to understand

  314. Pham

    Thank you so much for your informative & useful “How to Knock off Any Cosmetic Product” book. It’s very helpful for the new beginner as me to start to be a formulator and catch up the progress quickly.

  315. B.Gh

    Thank you for every things. I need some formulation. you introduce some website such as “croda, evonik, innovadex, silab, lonza & lubrizol” but unfortunately some of them need login & register. I don’t know why these compaies don’t like introduce their raw material in a fomulation, perhaps customers have encouraged to buy their raw material. If you can, help us.

    1. Perry Romanowski

      These companies want customers that will buy large quantities of their materials so they restrict access to only chemists from larger companies. You can try to access through distributors.

  316. Conrad Ruiz

    I’m not a cosmetic chemist, and yet this short guide provided me with a much better understanding of cosmetics chemistry than anything else I’ve tried to read on the internet. Kudos.

  317. Chrix

    What a nice book for newbies like me. I appreciate the good work you are doing. Thanks and keep it up

  318. Anna O'Regan

    Thanks I thought the report was really interesting and informative for someone who just starting out like me.

  319. Skinwin Soap

    I read all the content and it is very good, so informative. Thank you for doing this article, appreciate it. I am new in this business and I learned a lot from reading this article.

  320. Audrey

    Being a chemist who is working in business, I found this really useful considering I am looking at starting my own natural cosmetic line.

  321. Marika

    This report provides very useful information on how to start a cosmetic line. It is well written and easy to follow. I found it very helpful because it provided me with additonal basic information that I believe is essential for anyone who wants to be part of this business.
    Thank you Chemist Corner!

  322. Essie

    This guide was exactly what I needed! Incredibly helpful as a starting point for a budding entrepreneur in the cosmetics industry. Thank you Chemists Corner :’)

  323. Pamella

    Thank you for your detailed specificity. I now possess the tools to actually “knock-off” a cosmetic formula. Yay!

  324. Takeisha Hollingsworth

    This book came right on time. I’ve been looking at ingredients to figure how to formulate a like product. Now I have a guide to help.

  325. Joanna

    How to knock off any cosmetic formula is informative but not as much as I hoped it would.

  326. Davor

    Can’t say much of anything about knocking off the product. I’d rather the majority was spent on improving the product rather than knocking it off.

  327. Cheryl

    Very good information, thanks!

  328. ezafariza

    Very informative.
    I wish i knew where to get those chemical ingredients and can buy in small amount to execute the experiment

  329. Kathy

    Excellent Resource for how to create knock-off products. You bet I will be saving this document. Thanks a million

  330. Zohreh

    Honestly these information is very useful for me.Thanks a lot.

  331. Jessie

    Very Useful & Helpful for a new chemist…..kindly share more!~~

  334. Thang Nguyen

    Great, simple article outlining the technique on how to knock off a cosmetic product. Concise and very easy to understand, even for a beginning chemist. Found article to be definitely useful.

  335. Dimitri

    A good document. At the first I suppose that it is very easy to duplicate any formula, but at the end of the publication we must work hard for this.

    The little book on how to recreate a cosmetic formula was helpful, concise – the way I like it thanks for not wasting my time!, and well written. Thank you!

  337. Kimberly Schiltz

    Thought it was good information.

  338. Patricia

    Thank you! This book is very helpful and it gave me outline on how to actually discover the formulation of a cosmetic product. I hope to be able to read more books like this! 😉

  344. Lisa Marie

    Hi Perry I’m a full-time flight attendant I haven’t had time to do my courses yet because of timing I’m going to watch them this weekend on top of that I also operate run and all natural and organic skin and body care business. A question is will taking cosmetic courses help me in running and operating my business I’ve taken some online formulating and marketing business classes for all natural skin and body care businesses but that’s about as far as I got I was just basically wanting to educate myself so I can make a better product for my customer. Thanks again Lisa Marie and I did also find the first video on copying market products very helpful and interesting.

    1. Perry Romanowski

      If your intention is to market and sell a product line, you don’t necessarily have to know how to make the products. In fact, it’s more important that you learn how to market the products and leave formulating to professional chemists. You might find our free report helpful. http://startacosmeticline.com

  345. Anubhuti Ghosh

    Hi Perry, this report was not only very informative and useful but a very good guide for beginners to understand formulation designing.

  346. yvonne Richards

    thank you this the power of knowledge that I can achieve what I was looking for long time

  347. LaTanya Demars

    I’m glad I found Chemist Corner. The e-book contains a lot of useful information, and links are helpful as well.

  348. Emer

    I am a perfumer, not a cosmetic chemist and found this article simple to follow and very helpful. Some of the advice is a handy reminder of good practice, and some pointers (like checking the patents) are things I wouldn’t have otherwise tried, which will save hours. Thank you!

  349. Rachel

    Interesting insights

  350. bahareh farasati far

    Really helpful,thank you!

  351. Erica Jones

    This site is just simply AMAZING. I’ve already learned things I did not know. This is my hugest dream in tgr world, and I want to give a big thanks to the Chemist Corner for helping me go full force with following my heart and fulfilling my passions and dreams. I couldn’t have done it without the Chemist Corner!

  352. Florence

    I have read through the report and found it to be very informative. I’ve saved the PDF into my ebooks so I can go back and re-read anytime I want.

  353. Marijana

    Book is very usefull. I like it, it helped me understand some things better.

  354. Lawrence R. Carlson

    Greetings Perry,

    I found your piece most useful, applications-oriented, methodical and logical and well-rounded in content. I’ve been formulating for 38 years for Fortune 50 Companies and would be proud to incorporate this into a SOP/Work Instruction format for Strategy of Formulation since so many younger formulators do not have access to this knowledge and certainly isn’t taught in mainstream academia.


    Lawrence R. Carlson


    Very useful sessions

  356. Gugulethu

    Very informative and useful

  357. Jini

    It was great! With the information of this ebook plus some notes I took on the challenges of “30 days to become a better formulater” was really awsome, who would have thought a spreed sheet would be so helpful?!

    Can’t say it enough, thank you Perry for creating this corner!

  358. Maia

    This is very informative, but a lot of work to do. Thank you

  359. Victor

    Very enlightening write up. It’s has taken my interest in cosmetics science to a whole new level. I personally took note of the advice at the last part. ” Be Creative and innovative in your formulation and not just knocking off other people’s products formulation

  360. Nikkie

    I have always loved chemistry and cosmetics. This composition certainly fueled my passion for the combination of the two.

    Thank you for all the information in this book. I’m a pharmacist myself, but, sadly, they don’ t teach you this at university, even the most basic things…so I found the suggestions very useful and I already started using them in practice. I’ll definately check this webpage and forums for more related info.
    Thank you for the great job you’re doing helping others!

  373. Jamie

    Very informative! 😉

    Thanks again and do keep it up.

  378. asavela

  379. Monique

      1. Roritta

        Hi Perry
        Can you send me your email please?
        I need some informations about the course plz

  380. Catarina Rocha

    Well, first of all: thank you. It takes a lot of effort to gather all that information and put it in a way it is easy for the reader to follow. And you did it for free.
    It was actually really useful for me, since I’m not a chemist myself. Just someone who’s been trying for a while to make all my products. I find that it makes me aprecciate them more and use them in a more controlled manner and save a lot. I’m already using that info to make a hair product that I want to copy. We’ll see if I’m successful…

    Thank you Perry.

  381. Gisela Villalobos

    I think this book provie basic information to begining in the world of cosmetic science, such a basic book is good. thank you

    The guide , “How to knock off any cosmetics” is a great summary of first steps into making good quality cosmetics. I appreciate the added links to additional web sites for further information. Very useful and concise instructions makes creating cosmetics easy. I would like to find more information on how to perform a safety/stability testing on my own , as so far, I was not able to find any information on it. If the only option is to send samples to testing labs, could you please give my a link to those facilities in USA. Thank you Perry for sharing your time and great knowledge with all of us.


  391. Leisha

    It has useful information for someone looking for this sort of information – authentic stuff with a scientific basis unlike a lot of information on the internet. A great go to blog for authentic information. I am looking more for natural and herbal formulations, information on both ingredients and results, hope you cover more of this in future reports too!

    Thank you so much for the information! It was very helpful

  401. Mümin

    First of all, thank you for the valuable informations. It’s a very nice roadmap you sent me. I’m a chemical engineer for 25 years. But I’m new to cosmetics. Normally, I have collected cosmetic informations similar to the waypoints in your roadmap for 10 years. The main issue I work on is the application of humic acids in cosmetics. I have produced new products and molecules in this area. For example, PVP / sodium humate biomolecule. I gave a name to this: HUMIDONE. In addition, I made a black peelable mask from the PVA / potassium humate biomolecule. I produced a black shampoo from potassium humate based on soft soap without using SLES and water. My studies continue similar to those by making new bio-molecules. I also review the extra informations submitted by you that I find on youtube. I store every useful information coming from you. Thanks again for your contribution and interest. Best regards…

  402. Julie

    Interesting for a start. Thank you for the tips 🙂

  403. Linda

    Hallo Perry, I’m italian, sorry for my engish not so good!
    I’ve read the document “How to Knock off Any Cosmetic Product” and I hoped it was more deepened.
    Unfortunately it didn’t give me much more information compared to my knowledge.
    But thanks a lot because I treasure your effort for all of us!
    I’ll continue to follow your website!

  404. Wendy

    The report was not really that useful to me as I don’t want to duplicate products at present. However it’s all a learning opportunity.

    The information you provide is just what I needed. Now I have a starting point for my new private label skincare line.

  420. Sofia Olvera

    I am a junior in high school and highly interested in chemistry. I specifically want to study both cosmetic science and chemistry at FDU. Do you have any advice? Do you think that majoring in chemistry alone is a good idea or should I study both cosmetic science and chemistry?
    I really enjoyed looking through this article and learning about the cosmetic formula.

    1. Perry Romanowski

      Yes, majoring in Chemistry is a good idea.

  421. Ann

    Really enjoyed reading through this and gaining a better understanding of formulating. Would have liked more information on patents and navigating the details contained in them because I found looking through some challenging but there are so many other sources of information you detail that it isn’t at all a problem. Thank you. Great report.

  422. Alynna

    Thanks for the info it really helps me alot si ce im starting to make cosmetics products i can use all the iseful info thanks so much and never stop inspiring and giving relevant information thats people can use. GOD BLESS!!

  423. Jeff

    Hello Perry, a brazilian chemical engineer here. The “1% rule” is the most simple, useful and “how did i not think that before” thing that i’ve ever read, on this subject. i just want to thank you.

      Great! I’m glad it helps

  424. Ariel

  426. mehrozkalim

    thanx for ur amazing resopnse…

  427. Fredrick

    Reward or not, I will comment:
    I downloaded the book “How to duplicate any Cosmetics few days ago and immediately, I took out 45minutes to read it through and it has been so helpful.
    1. I was able to learn how to identify the major ingredients in any cosmetic product using the percentage composition.
    2. How to improve on existing brands and produce an outstanding product.
    These are knowledge I couldn’t get in my B Sc study combine Biochemistry and Microbiology.
    I strongly recommend this material for anyone that wants to be outstanding in the cosmetic industry. God bless Perry 44.

  428. Randy

    I thought the information in the booklet was excellent. I soon as I get the money I am going to enroll into the course immediately to get the professional training you offer on how to understand and actually make a product to put on the market.

  429. Taher

    The book is very informative and easy to understand, I hope to hear about courses and lessons with Arabic subtitle if possible

    thank you a lot

  432. Katrin Suchan

    Very interesting report, thanks! I’m not a chemist but a DIY formulator making all my cosmetic products myself. It’s helpful to know these ten steps but for me personally it’s more interesting developing my own recipes.

  433. VERA

    Thank you for all the great references you made in your report. It was a great read and look forward to using the information in the future. Grateful for your generosity.

  434. Rachel

    Thank you Perry

    1. Anne Lucas

      Its a lot of information, I do thank you for sharing your knowledge.


  435. Bree

    Upon deciding to start up my own makeup line it has proven to be very difficult to find the info I was searching for… Until I came across Perry Romanowski’s website. With such limited information on the internet, Chemistscorner has been absolutely wonderful. With both the business and chemical side of running a cosmetic line easily available, I would recommend this site to anyone looking at going into this industry and look forward to participating in the courses that Perry has to offer!

  436. Terry

    Thank you so much. Always informative and educational. Please keep doing what you do.

  437. Diksha Wadhwa

    Always looking for new ideas for science classes. I see possibilities here!

  460. Maria

    Thank you Perry for writing this ebook. It is very informative, helpful and easy to understand. More power to you.

  461. Malik Akramuddin

    I have gone through “How to Knock off Any Cosmetic Product”.The suggestion given in this write up is very basic in nature.Secondly,IR and Mass spectroscopic analysis of skin creams and lotion and other cosmetics products is not easy and also not easily available.For A beginner in cosmetic manufacturing such instrumental analysis is also not affordable.Over all write up is useful for an entrepreneur who is not knowing anything about cosmetic manufacturing.

  462. sven

    I am already trying some of the things out in there.

  463. Miriam

    Thanks for your amazing acknowledgement. nice to hear more from you.

  464. Pauline Lam

    I found very useful information and references from the website. Thanks so much for the hard work!

  465. Beverly

    I got the “How to Knock off Any Cosmetic Product” report, and it is absolutely great. The report is very organized, easy and interesting. Thank you

  466. Leonette

    I loved the report. I am a beginner in cosmetic science/formulations and this report was an easy read and very informative. It also sparked my interest even more and I found it be very useful. Thanks!

  467. Tanya Nyman

    I really enjoyed reading this little gem. My background is in natural sciences so mixing chemicals to get awe-inspiring results is a passion. A great section to go through was the 5th step on how to systematically analyse the ingredients list of a product. I also appreciated the suggestions on where and how to gather information (didn’t think about suppliers as information magnets before). Overall a this brief read really motivates one to get involved in the process of product research personally with the added benefit of hinting towards building on this base to create innovative products.

  468. Olivia stan

    The information realy helped me, to see the reality, is more complicated than i thought. So thank you sharing this information for free

  469. Sapna

    Thank you so much!!
    It could not have been better!

  470. Ximena

    I really like the report for a beginner is a good tool. Thanks

  471. Virginia

    I found the report very useful, things I never thought of, places where to look for information. This was very helpful to me. I am not in the cosmetic’s industry; I am hoping to make my own chemical free products. Shampoo, conditions, face wash, stuff like that. Thank you for the report.

  472. Erika Loxx

    This is great, it really got me thinking!

  473. Richard

    It is very nice of you to take the time to share your knowledge. I found it very helpful, Perry.

  474. Christien

    What may seem as obvious can easily turn into frustration. Following this very easy process helps organize your strategy and find results making it a great tool and wonderful insight.

  475. Tobi

    great site. very informative for a beginner.

  476. Thang

    The report was providing useful information and still related. Wished to have the copy when I was junior. Thanks Mr. 44

  477. Carrie

    Logical and easy to follow – Thank you, Perry!

  478. Sonny Horton

    As a new COO of a Cosmeceuticals startup, this e-Book helped me gain a bit better understanding of what’s behind the curtains. I am the business/operations guy and my partners are the science/medicine folks. This really helped and I look forward to additional material.

  479. Holly walker

    Thank you Perry. You have helped tremendously.

  480. Jo-Anna Cassino

    I really loved this and thought it was very useful! Thank you!!

  481. Neil

    No real information here, just some common logic. I suppose I’m relieved that I was doing it right already but I am disapointed that there wasn’t any real tips, tricks, strategies or techniques described.

  482. Bethy

    Very informative report and useful for those starting in cosmetic formulation.

  483. Lyes dahmani

    I found the report very useful . Thank you very much perry.

  488. Gabriele

    Thank you for this helpful article. A nice guideline how to analyse good products on the way to create a own one.

  489. Lydia

    Very helpful and insightful for people new to the cosmetic industry, like me.

  490. Nhi

    It’s really good basic information with “How to knock off with any cosmetic products” report. It’s nice time to review and follow the procedure again. From this I can re-arrange step by step when preparing any products.

  491. Susan Stowell

    Very informative info. Would love to purchase your book but a little pricey for me right now. I’m sure it’s worth every penny and will save up for it!

  492. Deb

    Good information. Would like to find out more about formulating on completely natural bases without parabens, petrochemicals etc and know what each of the ingredients are used for.

  493. Chris Tome

    Very helpful and insightful information, thank you SO much!

  494. Mani Ganesh

    it was so informative and easy to understand

  495. Michelle

  498. OSAYANDE, Ehis

    I am a Bachelors Degree holder of Industrial Chemistry from University of Benin, Nigeria (presently at Masters level in the same field in the same institution). Its been so amazing since joining here. I have made very speedy and tremendous progress in my research and I hope to achieve greater things. Joining here has made my work easier and more interesting.

  499. ana

    Very interesting. I have a question : if an ingredient has several functions ,
    as I know what the main function.

    1. Perry Romanowski

      The main function is whatever reason you mainly add an ingredient. Only the formulator would know for sure.

      1. rosemary

        hello, just listened to the report and it was fascinating, am not a chemist but am interested in formulating or developing hair products. cant wait to get started with you

  500. Esther

    It is very insightful especially to someone who had no prior knowledge to cosmetic formulation. This is a good start to becoming a skincare formulator. Thank you for the report.

  501. arshad ali

    As this is the starting point

    1. Perry Romanowski

      I don’t have one that we’ve formally put together. You just need to include a listing of physical characteristics of the formula (color, odor, texture), function, cost, bottle, etc.

  523. Wes

    Very helpful and informative to start up a formulation for little formulation experience user

  524. Tiare

    Dear Perry,
    In “How to Knock off Any Cosmetic Product” report. Step 8, for skin lotion test, using instruments like Novameter, Cutometer, Twistionmeter, or dequamation dics.
    What parameter is for each instruments, respectively?

    1. Perry Romanowski

      That’s a complicated question without a simple answer. It really depends on the type of test you are running and what you are trying to prove / achieve.

  526. Ngan Phan

    Thanks a lots, Perry
    I have just known this website through my friend. I am so surprise that all of things you share are very practical for a R&D. It’s sure that I continue following this website to extend my knowledge.

    The information is useful for a beginner like myself. Thanks Perry

  533. Lynnet

    The content is going to be helpful to me since am starting to formulate my own products soon….just what i needed :), though how can i access a spread sheet program to arrange my formulas ..i have never used one.. plus what is INCI in full and how can i access it as well?

  534. Carine

    I have been making my own cosmetic products for several years but I have only tried to duplicate 3 or 4 products. This book will certainly help me, thank you.
    I’ve got a question though about the 1% that may not shows in American products ingredients list. I thought this 1% could only concerns some ingredients specially formulated by the company (kind of secret ingredient), something that could not be found in other brands. Could you please confirm that this 1% could be anything from fragrances to preservatives?

    1. Perry Romanowski

      Yes, 1% could be pretty much any ingredients.

  535. Kiet

  552. Gerald

    I have wanted to know more about the ingredients in cosmetics for a really long time. Whenever I would look at the list on a box or bottle, it was confusing. What is this really long named substance. Should I be using it. Can I make something myself. Peter Romanowsky answer some of these questions immediately, and showed where I could go next to learn more. It’s like having a friend in the cosmetics business. Thank you, Peter.

  553. Dr.Bassam Bitar

    Hi Perry

    Thanks for your free book “How to knock off any cosmetic product”. It provided some good guidlines on how to start the knock-off process.

  572. Obdulio Cerceño Ch

    Hello Mr. Perry Romanowski.

    Thanks a lot for the download Report. It is very useful tool for guidance. I am a empiric inventor and like to read. My area is not cosmetics. Although, I am working and developing nanotechnology products at local level. In doing so, I am so glad I found your site because helped me greatly to be more efficient about finding clues and important data that will help me to develop some formulas I am searching for.

  574. Paulo Vitti

    Thanks a lot!

    it’s usful and easy to understand. thanks a lot

  576. Zue

    Hi Perry,
    Thank you very much for putting together this excellent book! While it is very informative and very helpful to both young and experienced cosmetic chemists, it also provides encouragement and inspiration to those who are faced with challenging and difficult projects. Would it be possible for you to include general tips on how to deal with unstable formulas?

    1. Perry Romanowski

      Hello Zue – I’ll have to work on a different book for that. We’ve written a bit about that elsewhere on the blog so I’d suggest you do a search or look through our forum.

  577. Ndiyo Hilaire

  596. Melanie M

    Very interesting read. However it would be nice to have more information on the different lab tests that can be performed. Also, gender neutral pronouns should always be used if the author is talking about the reader.

  597. Zaid

    Hey there
    Am really happy that i found your website, its helpful, useful and genuine. The book “How to Knock Off Any Cosmetic Product” is a great start for people like me who is new to cosmetic chemistry and cosmetic industry, hope to see more of such practical and straight to the point books in the future.

  598. Samantha Chepi

    I found the report very useful for someone like me that wants to build a cosmetic brand and not really sure of what to do or where to start and everything else. Although I didn’t understand most of it because I am a beginner in this category, you made it easy for me to at least grip on the main Do’s and Don’t’s

  599. Tren A

    Good basic introduction.

  600. Dimakatso

    Thank you for such information.
    I am starting to look at labels differently now. Now they make more sense.

  601. Marie

    Thanks very much for the great article. I found it very informative and useful.

  602. Mattu

    Every points on your report is very useful . I’ll try when i learn formulation . I am just a beginner

  603. Mattu

    Thanks Perry.
    Every points on your report is very useful . I’ll try when i learn formulation . I am just a beginner.

  604. Aggie

    Thank you very much for sharing your knowledge for free! Im hungry for more! 🙂

  605. Annalisa

    I thought your information was very generous and very helpful. I have taken all your advice on board and am looking forward to more lessons from you ! A great service and thank you very much!

  606. john karlik

    a good intro, points the direction to find out what you do not know

  607. Margaret Anne

    Good content – gives me confidence to start formulating!

  608. Ana

    Thank you so much for the e-book, i will practice some of the tips. very excellent written by the way

  609. Gisselle Ramirez

    Thanks for everything I’ve learned about chemistry and it was very helpful.I do appreciate everything mostly this because its what I always wanted to do

  610. Candace Wallace

    I found the 10 steps formula to be very informative as I dive deeper into learning and becoming a part of this fascinating and evolving industry. I am excited to learn more through this wonderful training course and the connections that I will inevitably encounter during my journey.

  611. carla jepson

    I thought it was great…… will probably re-read it a few times. I would love to get actual formulas that are for formulating organic skincare (from home). I find the preservative issue with a lot of the new accepted emulsifiers really tricky. Most of the ‘natural’ new preservatives all seem to have down sides – viscosity reducing, PH sensitive etc. Its a mine field out there for non chemists like me!

  612. Vijaykumar R Zala

    Hi perry,
    Basically i had done my M.Sc in chemistry and I moved in cosmetic industry.
    May be after one year or more than that i am able to get the complete information to “knocking off” a product. I appreciated the effort and hope more of these come in the future because for fresher it will be very very helpful.
    Thanks a lot dear.

  613. Dale Ann

    I found it a nice step by step tutorial on how to start out formulating.

  614. Nicoleta Dimitrova

    Very helpful and practical information. I hope the “1% Rule” is applicable in Europe, too. /I’m from Bulgaria/.
    Best regards,

    1. Perry Romanowski

      It is applicable in the EU.

  615. Anthony Norris

    I found the information very helpful.

  616. A

    An excellent document, written in an accessible style. Some of the information given is (or should be) commonsense but overall a very useful and informative report. Thanks, Perry!

  617. Na

    Neatly organized and helpful ! Great way to start 🙂

  618. Mike

    Nice, very helpful. Thanks for being honest, keep it up and be blessed.

  619. abbas

    Professor Perry

    This beneficial knowledge by serving humanity.
    I hope to communicate with you time. I work in detergents and cosmetics
    I will be delighted to send me about my Formula NES
    Thank you ….. from Iraqi Kurdistan Abbas

  620. Sajata

    I’m delighted to have discovered “Chemist Corner”. “How To Knock-Off a Cosmetic Formula”, it is a wonderful tool for my research. All the information you’ve provided is nicely comprehensible and concise for a novice like myself. Thank you!

  621. Cassandra

    Very helpful tips!

  622. Vladana

    Very useful, thank you very much!

  623. Farzan

    Very useful…..it was really helpful.

  624. Okon ekpa

    The book gave some basic information like the order of listing ingredients on the product labels.but what I really need is how to create recipes of my own or modify existing ones to generate new products as the ‘knock off’ process is really time consuming.

  625. Tahir

    It is a good basic information for beginners.
    But i m not intresting to duplicate any formulation.
    I want to creat something own.

  626. ben sam

    thanks very much for the information. really helpful indeed!

  627. Dragos

    As a beginner in Cosmetic Formulation, I found this read to be a very informative one.
    Thank you Perry

  628. hailey

    Thanks for your interesting lessons! very helpful!

  629. Marzia

    Hello, I’m very happy to discover your webside, it’s very interesting; above all I’m peausure to receive your e-mail with lesson.
    Thank you very much Look forward to your next mails

  630. Choma Matale

    I have read the book and I have thoroughly enjoyed because it. For me it is to understand and therefore I do not have any questions because everything in it makes senese. In fact going through this report have helped me to change may approarch to making a formulation. Whereas I have been making trial and error of making something and afterwards I triy to compare it with existing products (and it takes a very long time) now I will start with existing products of interest and probably reduce the time by 75% or more.

    It was a very good reading and thanks a lot. It provides a good foundation on formulation and may be there is other material that on can study to advance to the next level. Once more, thanks very much I have enjoyed reading this material and Ithink I will keep coming back to it for reference.

  631. Simona

    I was very happy to find your site. I used to work 15 years in R%D for cosmetic but it was 16 years ago. In last decade I am giving the lectures from cosmetology for students. I was just thinking how to refresh and make more interesting my classes and I found your corner. This inspired me a lot.
    I went through titles and contents very briefly…for now I can just say that I am very thankful that I can use this knowledge for m y work…later on I hope I will be capable to give also some constructive remarks.
    Thank you for encourage me to participate in this communication.
    Beside you made an impression on me also with mentioning Amway. I am ABO in SI looking to spread networking globally… Products are incredible …business opportunity also…
    Going back to lectures…my I kindly ask you for some advices, please…how to make lectures more attractive for students ….what to do to became better teacher…
    Thank you very much for your time. Look forward to your reply.

    1. Perry Romanowski

      To make lectures better for students…I don’t know. You just have to practice a lot and make changes when things don’t work right. Keep doing the things that do work right. And juggling. People like juggling.

  632. Mona

    I appreciate the insight into this matter. I will not try duplicating someone else’s formula (ethical decision), but it was interesting to learn about the basic composition of cosmetic formulations anyway. Chemist’s Corner is a helpful site to start-ups, thank you!

  633. Luis

    Thanks for this piece of work! I found it very useful for starting in the formulation world. Definitely worth!

  634. TUAN

    Thank you for your interesting lessons

  635. Carlos

    Very useful, thank you very much

  636. Stefano

    Very concise and helpfull for starting formulators.

  637. Eva

    I found the report very enlightening and easy to understand for budding formulators. Having this blueprint is invaluable when you start formulating; it’s not just about copying, it’s about learning what makes a product what it is, and as you gain confidence, starting your own R&D based on that knowledge.

  638. Valerie

    This was informative, but I’m particularly interested in creating products out of 100% natural ingredients (I know, “natural” can be construed to mean a lot of things). I mean ingredients that are directly derived from plants–oils, butters, waxes, essential oils, hydrosols, etc. Those don’t fall under the typical class and use of the kind of ingredients you talk about. When I’m looking at natural products, how can I classify and break those down?

    1. Perry Romanowski

      See our website for articles about natural formulating.

  639. Ugochi olabisi

    I learnt How to use an existing product to derive the prototype. Writing down the ingredient panel then Seperating them according to their functions. For instance conditioners, moisturizers or surfactants. Bearing in mind that the percentage content of ingredients are usually in descending order in terms of value I:e 70%_ 10% etc.

  640. Navya

    I am realy happy with this website because it realy helping me lot in my project work…
    Thank you

  641. Ugochi olabisi

    Reading through your site , I have mor understanding on the first steps to take towards formulating a product. listing out the chemicals in the ingredient panel first. The grouping of chemicals into their functions then percentage composition. This has been helpful.

  642. Meg

    Thankyou, it was very informative, gives me somewhere to start, can’t wait to start mimicking my favourites.

  643. azlan

    i do like cosmetic field industry. I wanna create a product as natural to replace synthetic product in the market. Moreover less information to do my own product, luckily when i downloaded “How to Knock off Any Cosmetic Product”, I can get some idea and knowledge how to start my cosmetic business.

  668. julia

    This article is about taking a forensic approach (a series of logical steps) to solve a problem, in this case replicating an existing cosmetic product. Will you be able to replicate a product just by reading this article? No, but it is a good first knowledge step of how to think and and where to look.

    For me is very interesting the formulation of very low viscosity lotions and serums with collagen as an active ingredient, to be applied as an spry.

  676. krisztee

    It was helpful and useful 🙂

  677. chuks

    the site did not open so it was not possible for. me to download the stuff.may be you are not aware of the promblem

    1. Perry Romanowski

      You probably have to ‘right click’ the link then save it to your computer. Sometimes if you don’t have the capability to read .pdf files in your browser you won’t be able to see the book.

  678. Carla

    I appreciate the information Perry shares so graciously. I never thought information would be assessable to me. I am excited for the journey.

  679. NR

    Perry thank you for sending me a copy of your most informative book ‘How To Knock-Off a Cosmetic Formula’. The way you have laid out the steps sequentially delivers the material to my tidy mind beautifully and I love the way you have included links to relevant sites, this is so helpful. I see you this ebook is written to a broad range of folk, from the beginner cosmetic scientist to those with access to labs. I look forward to receiving your Cosmetic Science Introduction Course 🙂

  680. Afroditi Tsesmesidou

    it was interesting

  681. Idowu afeez

    Its quite educating and beneficial,which will help we undergraduates be self employed after graduating as a chemist..looking forward to hearing from you..tanks alot

  682. Stephanie

  683. Terry

    Thank you Perry for your generosity. I found some of your information very informative and am looking forward to reading your book “Beginning Cosmetic Chemistry”. Thanks again.

  684. Juliet

  685. joe wolf

    Thank very much for the oppertunit to start the course

  686. Maureen Tarulli

    I am still reading through this report, but as an educator, (in collaboration with other HS educators) I feel this is going to be VERY relevant and informative to students. We are trying to help them see applications of Chemistry in REAL LIFE and your report is full of information that will help students see how Chemistry can apply to the products they use in life, PLUS, hopefully, it will provide information that may even influence student’s careers and ideas for their future! Thank you for making this available for FREE for educators and others that are interested!

  687. Ashish Pawnikar

    Dear Perry,
    It’s really informative & useful to crack the formulation of competitors, we called it ‘Tear down’ of product, i am doing this practice from last 3yrs. It is very helpful to new comers to learn & even for experienced professionals also. One would get idea of claims of the product which is of great help. Even we can expand our ingredients vocabulary & update with the new ingredients & technology which is happening in this glamorous world of beauty.

  688. Luisa Guevara

    Your report is an excellent tool for those of us who re in the process of starting our on business in the cosmetic industry. The suggested reading material is great! Thank you for sharing with us. I cant wait to read more on your site.

  689. Monique

    Hi, I have not finished reading it, but so far it is interesting and surprising of how easy it is to make a knock off. I am not a cosmetic chemist nor studying towards becoming one. I am however very interested in starting a face care range containing antioxidants. The tips and comments on chemist corner I find informative and helpful. Thanks


    Although I haven’t finished of reading your book, I assure that your book is so fabulous. I gained a lot of knowledge from your book. I feel that I so lucky to have your book. thank you.

  691. Jamie Carman

    Very informative reading with a good supply of extra help with outside information links. I found one in particular called CosDNA which is very helpful. Thank you Perry

  692. Donna

    I recently started making my own “anti-aging” serums and have been impressed with the effectiveness of the serums I’ve made already. I wanted to gain more insight into the ingredients that are in products in the stores and spas and how they contributed to the end product – so happy I found Chemistry Corner and downloaded the How to Knock off Any Cosmetic Product report. I’m starting on a new moisturizing product and this report has proven to be instrumental.

  693. Lindiwe Gontsi

    I really learned a lot in the knock off pointers. I would however like access to the beginners chemistry book. Thank you.

  694. Naima

    I find your mini book very useful as I am a beginner so I work on existing formulas actually I have a formula of a hand cream which I use 3 or 4 years very good cream especially in winter i’ll try to find out the percentages of its ingredients and i’ll tell you
    I am from Morocco so some of the steps are not possible for example using patent all I have is the ingredients on the packaging and trying the product. my other problem is names for example polyquatenium-10 there are various those which are highly cationic and less viscous and those highly viscous what to tell the supplier

  695. Edwin Stevenson

    Greetings from Durban, South Africa. I am currently doing cosmetics training with Professor Francis Shode. Your information will be most welcome, and will increase my knowledge and interest in the industry. I look forward to receiving your emails. Kind regards. Edwin

  696. May

    My grandfather was a pharmacist and he used to make medical and cosmetic products, I never met him but I think I like to learn those things from my councious mind and he will be proud of me!
    Thank you for the courses you are offering to us.

  697. Marja van der Heijden

    Your report is the first comprehensive and detailed explanation of how to go about the knocking off process. Extremely helpful!!!

  698. Marco Rafael

    Dear sir, I am very glad to have received your report. I am starting a business in cosmetics and the information received is very useful.

  699. tn

    The report is extremely informative and easy to understand as a student like me. It’s a great start so far.

  700. Domingos J C Spinelli

    To be very honest with you and pardon my bluntness, I did not learn much more than I already knew.
    I expected to find more information about natural and sustainable ingredients such as nature; oils, extracts etc..
    At any rate it is a very good piece of information put all together

  701. Gerard

    Very helpful and informative. I’m trying to educate myself.

  702. Dr.usama

    This looks awesome as this will make me more competent as a cosmetic formulator…

  703. Kristal Bull

    Useful primer on formulating natural products, thank you

  704. Haile

    very helpful, professional, I am a chemist working on cosmetic manufacturing I will also contribute soon.

  705. Gagandip

    Great quick read for an intro to formulating. It is an overview of the process which will help you get started, but you still have to do lots of research on your own

  706. Marian

    Really I’m very happy to find an information source in this field and I’m glad to say it is very useful

  707. karen

    Thank you so much. Very insightful

  708. Anj

    This was extremely helpful.

  709. michelle

    Info very information. I have already started doing what is recommended. Lots of work to go on to do. Did lip balm last year was very successful. Told I should patent it. Thanks for all the info.

  710. Alex

    As there is not much free information about this specific field on the internet, this was an useful report

  711. Abygale

    Thank you for the report! I’m quite new at formulating – doing an awful lot of research on the web, buying recipes & trying them & readapting them, reading blogs & how others do things. I thought your report might help me make my own instead of readapting everything which takes sooo much time; not necessarily creating a “knock-off”. I thought for me, it did give some helpful info in the “re-creating” area. I still have so much more to learn, & will implement what you’ve shared as I learn & begin to understand more. Thanx again!

  712. Arcadi

    I think it is very useful for beginners but also for more experienced people as a reminder.

  713. Rhi

    Thank you for the report. It’s a great basic guide as to how to start for a beginner such as myself!

  714. D'Mone

    Great Information and presentation..very informative..Thanks

  715. Marek

    Every professional should carry this book wherever he goes! Very interesting!!!

  716. Emily Chang

    It is extremely useful to me. It is very easy to understand and read. I have interest to know more from Chemists Corner.

    Thanks for sharing your experiences.


  717. parisa

    i found that book very useful and informative, great information for beginners. but you know i’m already in that bussiness and i’m looking for more pro information. can’t wait to get that mini-course by the way and thanks a lot.

  718. Megha

    Hello Perry, it was a great report. Explained in very easy language. It will be very useful for the beginners. All the best.

  719. Loukas

    Very useful information. Nice tips on how to dup a cosmetic product. Very easy to follow. Thank you so much for sharing all this info. Excellent work.

    1. Loukas

      Can’t we also start from a simple measurement of the water content (i.e. place the sample in an oven, evaporate all the moisture and weight the solids)? We could also have a measurement of the total fat content (i.e. extract the sample with a solvent, evaporate the solvent and weight the remaining fat). With these two simple experiments we can have a good estimation of the water phase and total oil phace percentage in the cosmetic product we want to duplicate. This could be our initial point before we start making several trials in order to match the composition of the product we want to duplicate. Is that right?
