Recommended Additional Resources for Cosmetic Chemists.

These will be occasionally updated so check back on a regular basis.

Getting Started

If you want a refresher on basic chemistry, the following is a good introductory textbook.
Virtual Chemistry Textbook

Learn the vital vocabulary.  Cosmetic industry jargon.

Here’s a list of websites that any cosmetic chemist will find useful.  Cosmetic Science web resources.


Chemistry and Manufacture of Cosmetics Formulating, 4th Edition

This is one of the original, complete set of books about cosmetic science. It is packed full of technical information covering cosmetic science, formulating and cosmetic ingredients. Almost every industry expert has written a chapter for this 4 volume book series. If you have a question about cosmetic chemistry, no doubt this book will have the answer for you.

Harry’s Cosmeticology 8th Edition

The first edition of this classic book on cosmetic science was first published in 1940. It is now in its 8th edition and is one of the most comprehensive tomes on the subject. It covers all aspects of cosmetic science in 5 sections including the substrates (skin, hair, nails), formulation approaches, ingredients, specific formulations, and production. As a formulation chemist, you will find this single volume book an indispensable resource that you frequently reference.

Handbook of Cosmetic Science and Technology, Third Edition

Much like Harry’s, the Handbook of Cosmetic Science & Technology attempts to cover as many aspects of cosmetic science as it can in a single book. This 880+ page work covers everything from the biology of hair, skin and nails to cosmetic formula types, cosmetic ingredients and even cosmetic claims. Of all the books mentioned thus far, this one does the best job of covering cosmetic claims and testing. It’s definitely worth having on your bookshelf.

A Short Textbook of Cosmetology

I don’t know where I got this book but it is a nice, short volume that covers the basics of cosmetic science. It was written by an author from Switzerland so it has a more Euro-centric view of the cosmetic industry. Other books discussed many focus on the North American cosmetic industry. I particularly enjoyed the extensive historical section in this book. The book is significantly shorter than others weighing in at only 435 pages, but it packs a lot of information in those pages.

Surfactants in Personal Care Products and Decorative Cosmetics, Third Edition (Surfactant Science)

This book is a bit more technical about the science of surfactants than any others on the list. It has chapters written by a variety of cosmetic industry experts and is an excellent resource for the advanced cosmetic chemist. It is probably not one you want to start with but after a few years of formulating, you’ll definitely want to have it in your cosmetic science library.

Chemical and Physical Behavior of Human Hair

This is the most specific of all the books on this list and its inclusion is more reflective of the fact that I spent most of my time formulating products for hair. However, if there is anything you want to know about the science and biology of hair, you need go nowhere else but this book. It explains all aspects of human hair and is based on the latest research. In the hair care world, the book is so ubiquitous it is simply referred to as “Robbins”.

Buyer’s Guides

In the cosmetic industry, Buyer’s Guides list the names and contact information of companies where you can buy raw materials and lab supplies. It also list places to have products formulated, produced, tested and filled.

INCI Directory – This is an excellent resource which lets you search raw materials by trade name, INCI name, and supplier. It also provides you with formula suggestions, news about the materials, and spec sheets. A great resource!

GCI Directory – contains a searchable listing of a variety of raw material, and packaging suppliers for the cosmetic industry. Requires registration but it is free to use.

Happi magazine buyer’s guide – Contains information about raw material sources, packaging and equipment, and testing services. It has a limited number of companies that are indexed.

Cosmetic Bench Reference – the most comprehensive free guide to ingredients and suppliers around the world. It provides the data you need to select the best ingredients for your formulating challenge. With more than 18,500+ ingredients and more than 600 raw material suppliers, the CBR online directory is a must-have research tool for industry buyers and chemists. Requires free registration to use.

Personal Care Products Council buyer’s guide – This is a good source for finding suppliers of various INCI approved raw materials on an International level. It is searchable by raw material name, trade name, and mixture name. It only provides listings for raw materials.


Inovadex – Over 5000 different formulas. One of the most extensive collections available. Requires free registration to use.

Happi Formulary – Not a bad collection of starting formulas. Searchable too.

Cosmetics & Toiletries – A listing of over 100 starting formulas.

Free starting formulas –  A list of over 50 sources for free starting cosmetic formulas.

Formulating Software

Mar – Kov Chemical Management software – Get a free trial here

Excel Formula template spreadsheet – This is a standard formula template that you can use and modify for your own needs.

Lab Supplies

Sigma Aldrich – You can get test raw materials and pretty much any lab equipment you need.

VWR – If you can’t find a lab supply here, it probably doesn’t exist yet. Over 400,000 scientific products.

Job sources

Careers in Cosmetics
This is a site that helps connect employers with job seekers. You can post your resume and search for cosmetic science jobs by job title, company, and location. If you’re searching for a job in the beauty industry, you should be looking here.
This website takes aggregate results from a variety of online job search sites and puts them conveniently in one place. You can search by job title or location. It also gives you alternative terms which will help you expand your search. For example, if you search for cosmetic chemist, it will suggest cosmetic formulator.


FDA Cosmetic Info — Everything you need to know about the rules governing the sale of cosmetics in the United States is here. Some say the cosmetic industry in the US is not regulated but it is, by the FDA. You can find information useful to both the consumer and cosmetic business owner.

European Commission — In the EU, cosmetics are regulated by a document called the Cosmetics Directive 76/768/EEC. At this website you can find the full-text version and also some important commentary on the implications of the rules. An excellent website for all things EU regulatory.

Health Canada — While it’s not as big a market as the US or EU, Canada is still a significant player in the cosmetic industry and their government wants to have their say. At this website you can find all the rules (current and proposed) that will govern how you can sell your products in Canada.

Ministry of Health (Japan) — While all governments have access to the same science, they don’t always come to the same conclusions about what is safe. At this site you’ll find out what compounds are restricted in cosmetics sold in Japan.

Cosmetic Ingredient Review Board — This one isn’t a governmental agency but an industry agency that reviews safety data about cosmetic ingredients. They report to the FDA and provide an excellent guide as to what ingredients you can and can not use when formulating cosmetics.

Complete list of worldwide cosmetic organic standards
A compilation of all the various organic and natural standard agencies. There is no single standard for the world so you must choose which is most appropriate for you to follow if you are creating natural cosmetics.

    Thank you for the excellent service you are providing. I have been in the industry for 45 years and I wish this Chemist’s Corner had been around in 1971 when I joined because it would have saved a lot of hassle! Please may I let your members know that my web site is full of published papers, useful links and other information. It also has information about some publications that are available as ebooks and paperbacks that fellow scientists might find useful!

    Keep up the excellent work

    Dear Perry

    Thank you very much. It is really very helpful to find everything at once place. Especially looking for particular INCI (when evaluating a composition of a cosmetic product) is sometimes challenging – especially for my students. If you do not mind I will share your findings with them.
    Since I am from EU I am also looking for some specifics for EU market…
    I found very useful following link: describing products with DMS(R) base cream for “treatment” of problematic skin…. I personally have some experiences with this base. (I developed creams for sensitive skin using also some DMD base) … however I do not know if this link fits to this topic…
    I am looking forward for addition news:).

  54. Avatar

    Hi Perry Thank you for getting all this info condensed in one place.
    I have been researching USDA NOP Organic standards, but I am still a little stumped as to why I cannot locate a complete list of ingredients that are approved for use in USDA 100% Organic products. Or is it based on each ingredient in your formula: you have to contact the producer to show the USDA certification documents and then your formula becomes automatically USDA organic as well if you are solely using their certified ingredients? Thank you in advance.

    1. Avatar
      Perry Romanowski

      Hello Tatiana – This is probably because there is no one who could really profit off putting together a list like that. The USDA is in the business of regulating food not cosmetics so they won’t do it. The raw material suppliers are only inclined to tell people about their own ingredients so they won’t do it. Maybe someday we’ll do something like that here on Chemists Corner.

      No, you can’t call yourself USDA organic certified just by using certified ingredients. Your production has to be observed and certified by an agent of the USDA before you get certified.

    2. Avatar

      I’m certain Perry’s totally correct re:the USDA, however, it might be worth your time to contact ‘Oregon Tilth’, if you’re seeking a starting point (& to greatly increase your label value, depending on your market)..they are a very legitimate 3rd party-objective assessment type of organization which is held in high esteem on the west coast, & possibly further. Regardless, they’ll certainly be able to give you some guidance as to the logistics of the process. Best of luck!

    Like you said, nobody wants to share their secrets, and especially their suppliers, yet you have opened the doors to all of us and expecting nothing in return, a true act of giving.
    You have taught all of us the importance of sharing our knowledge for not just our own personal growth and expansion, but to lend to others to enable them to grow as well.

I would also like to mention that the articles and information on your site are also very helpful. Since I am in Europe I always use CosIng ( in order to see if there are any restrictions in the raw materials that I have to use. And keep in mind to update that from 11th of July 2013 the new Regulation (EC) No 1223/2009 is coming into force instead of Directive 76/768/EEC.

    Dear Perry,
    I would like to congratulate you on the great work you are doing. Would also like to point out that you ought to mention somewhere that beginners in this business not to waste their time to register with innovadex because they will not be accepted. My company is taking the first steps in the cosmetics business, we are trying to decide on products, formulations and raw material suppliers. We have wasted our time to fill the application for registration with innovadex, the reply was negative for the reason that we do not have a web site with finished products and also we did not have any references from raw material suppliers etc. This web site is aiming to already established companies and chemists in the sector and not to beginners or the advertisers do not want any other business or attract more people in the sector. .

    got some queries in regards to regulations of some materials in cosmetics:

    1. Talc and silica – are considered hazardous due to its respirable silica content. they are still found them as one of the ingredients in cosmetics. how its usage being regulated in cosmetics and what are the implications?
    2. Acetone – what woul be suitable replacement that would comply with regulations?

    I found the ‘International Cosmetic Ingredient Dictionary And Handbook’ a valuable source of information for all aspects of Personal Care Science. It contains INCI, CAS #, Regulatory (Australia and Overseas), Suppliers, different functions of ingredients, Technical/Trade Names, Cross referencing to name but a few. It comes in 4 volumes and each volume is specific to the different categories. It has alot of information on raw ingredients especially when the Web is not always a good, accurate and honest source of material information. For anyone studying Personal Care Science or for ongoing research, this is a reliable source of information.

      Great addition Jan. Don’t know how I overlooked that one.

    I would also suggest two websites that are good ressources for ingredients information

    Lastly, 2 tips: you need mentors. The best option is a mentor within industry with a lot of years under their belt, that is still in the lab. But you can also find a good chemist amongst your suppliers. There are some. And enjoy their experience.
    Don’t forget to also acquire some basic business skills that will help you understand how the people that order work from you (marketing and your boss or your boss’s boss) function.

    Thanks Perry. These are very2 important informations. I, myself, can feel the progress I made as I always link to your info. From the US Patent info, formula template, HAPPI & C-T source of formula, the importance to write a blog, also the forum. Now, if I’m facing problem, whatever it is, I feel secure & sure that I can handle it because I have so many tools, right now. Frankly, I do surprise receiving this information.. complete & comprehensive. I’ll bookmark this! Thanks again.
