Sodium lauroyl sarcosinate is an sodium salt of an acyl derivative of sarcosine, which is a natural amino acid found in muscles and other body tissues. Acyl sarcosines are considered modifiŽed fatty acids in which the hydrocarbon chains are interrupted by an amidomethyl group in the alpha position. They are used as hair-conditioning agents and surfactant-cleansing agents in cosmetics, as well as to improve wetting and penetration of topical pharmaceutical products. Acyl sarcosines and their sodium salts are also used in the metal finishing and processing industries for their crystal modifying, anti-rust, and anti-corrosion properties. (L1892, A2881)
