To begin with, you may consult the classical texts of Sagarin and of Charles Zviak, former R&D Director and afterwards CEO of LÓreal Group.

Then put yourself in contact with the IFSCC and consult KOSMET database. There you will find everything that count in cosmetic science.

Cosmetic & Toiletries Journal is also a source for cosmetic formulations.

Dear Federico svarc, i need a book that can be downloaded, please send me any one in pdf formate

On KOSMET database you will find what you are looking for. Unfortunately it is not for free. You need to pay a fee for the search.

If not, you should try some of the russian "informal" tools to search what is available. I do not use them, but some friends do....

Hello Dear Zafar following book is available online, Hope they match your needs.

1- Cosmetic and Toiletry Formulations

2- Cosmetic Formulation of Skin Care Products
