Water-soluble polymers and their use in cosmetic formulations

摘要

Water-soluble polymers whose characteristic structural elements comprise units of the formulae I and/or IIwhereR1 is H, alkyl, cycloalkyl, aryl or aralkyl,R2 and R3 independently are as defined for R1 or are selected from substituted alkyl, substituted cycloalkyl, substituted aryl or substituted aralkyl, the substituents being selected from OH, O-alkyl, O-aryl, SH, S-alkyl, S-aryl, NH2, NH-alkyl, NH-aryl, N(alkyl)2, possibly in protinated form,N(Alkyl)3+3Z-, where Z is the radical of an inorganic ororganic acid, COOH, COO-alkyl, CONH2, CONH-alkyl, CON(alkyl)2, CN and SO3H; andthe indices x are each independently an integer from 1 to 20; and the acid addition salts of these polymers, (processes for whose preparation are also described), are used in cosmetic compositions.
