This series of handbooks, which is published under the auspices of the International Federation of Societies of Cosmetic Chemists, summarizes the many technologies employed by cosmetic scientists, whether analytical experts or nonexperts, for the analysis and quality control of cosmetic raw materials. Each volume is devoted to a specific group of raw materials. This volume outlines the chemical and physical tests which are generally performed on fatty raw materials widely used in the cosmetic industry. These materials originate mainly from purified vegetable oils, land or marine animal oils, fats and waxes or petroleum oils and waxes. Synthetic derivatives are developed from these natural sources. The series results from the collaboration of analytical experts in many member societies of the IFSCC and thus provides a broad spectrum of approaches to the technologies employed in cosmetic raw amterial analysis.
