This collections of 14 papers discusses the history, benefits, formulation, and future developments of hair and skin conditioning products, providing an overview of the subject and an analysis of the elements of conditioning. The first chapters serve as a general introduction, and review the biological and physicochemical aspects of hair and skin. The bulk of the book deals with individual conditioning agents used in hair and skin care products: petrolatum, humectants, emollient esters and oils, proteins, organo-modified siloxane polymers, silicone, cationic surfactants, and cationic polymers. The concluding chapters review factors to consider when formulating materials into finished products, and examine testing methods for evaluation of conditioning formulations.
