In response to requests to share the data accumulated over the past 45 years and especially the past twenty years examining the safety of cosmetic raw materials I am pleased to publish this book in order to help colleagues.At over a thousand pages it is impossible to supply all the references and it is hoped that this will not detract from the value of the work.The NOAEL (No Observable Adverse Effect Level) value is very rare and where such a figure does not exist I have used data and feedback from over 30,000 formulae of commercially launched products and any adverse feedback to create a virtual NOAEL figure that can be used to calculate out the margin of safety. The animal data, instrumental data, RIPT (Repeat Insult Patch Test) figures, and animal alternative test data have all been taken into consideration when producing this value.

This state-of-the-art reference provides comprehensive multidisciplinary coverage of the most recent information on cosmetic ingredients, finished products, target organs, delivery systems, and current technology in safety, toxicology, and dermatological testing. Discussing modern innovations such as active cosmetics for the hair, skin, and

Handbook of Cosmetic Science: An Introduction to Principles and Applications is a guidebook that aids in addressing several areas of concerns in cosmetic science. The book is comprised of 24 chapters that cover the wide spectrum of issues in cosmetics, from application of products up to the proper handling and packaging of cosmetic products. The text first discusses the importance of the body surfaces to which perfumes and cosmetics are applied such as the skin, hair, and teeth. Next the book deals with the chemistry of the raw materials that are processed in the cosmetics industry. The next chapters cover the formulation, production, and packaging of cosmetic products, along with product evaluation and measures to prevent damage to the goods. The text will be of great use to individuals involved in the research, development, production, and application of cosmetic products.
