Lysine derivatives, process of preparation, uses, and compositions comprising them

Abstract

New lysine derivatives containing a fluoroalkyloxycarbonyl or fluoroalkylsulphonyl group of formula: COOH--CH(NH.sub.2)--(CH.sub.2).sub.4 --NH--X--(CH.sub.2).sub.n --R in which n ranges from 0 and 4, X represents a divalent COO or SO.sub.2 group and R represents a linear or branched perfluoroalkyl radical having from 4 to 20 carbon atoms, salts thereof, and mixtures of the derivatives and the salts. A process for the preparation of these derivatives, salts, and mixtures and use of such derivatives, salts, and mixtures, especially in cosmetics. Compositions, especially cosmetic compositions, comprising the derivatives, salts, and mixtures.
