Welcome to this ‘novice’s guide’. At last a book that explains the real science behind the cosmetics we use.

Welcome to this ‘novice’s guide’. At last a book that explains the real science behind the cosmetics we use. Taking a gentle approach and a guided journey through the different product types, we discover that they are not as superficial as often thought and learn that there is some amazing science behind them. We shall uncover some of the truths behind the myths and point out some interesting facts on our way.

Did you know? Vitamin E is the world’s most used cosmetic active ingredient.; At just 1mm thick, your amazing skin keeps out just about everything it’s exposed to – including your products!; A ‘chemical soup’ of amino acids, urea, mineral salts and organic acids act as ‘water magnets’ in the skin keeping it naturally moisturised.; Discovered centuries ago, iron oxides (yes, the same chemicals as rust) are still commonly used inorganic pigments in foundations.; A lipstick is a fine balance of waxes, oils and colourants to keep the stick stable and leave an even gloss on your lips.

Cosmetic science and the personal care industry are often misrepresented. This book will educate and inform the public and the wider science community about the sound science they are based on. In the process many positive aspects of cosmetic chemistry can be revealed, from creating colours, fragrances and sensorial formulations to understanding the important interactions of UV light with organic and inorganic absorbers and blending these for effective SPF sunscreens. Providing background material for education and as an accessible scientific title for the interested lay reader, this book shows chemistry in an everyday context based on the real world and dispelling the many myths.

Arvustused

'The scope of this book is as wide as cosmetic science itself.'; 'It is a book that was written in a balanced way, one that caters for both scientists and for the general public.'; 'Consequently, the quality of Discovering Cosmetic Science is a result of the breadth of fields of expertise shared by all contributors.'; 'Discovering Cosmetic Science is current, relevant and scientifically accurate.'; 'The books content is of practical relevance; in this book, the reader will not find obsolete information or impractical theories, but instead will find established scientific knowledge that is used daily by cosmetic scientists for creating cosmetic products.' * International Journal Cosmetic Science *
