Surfactant-free cosmetic, dermatological and pharmaceutical compositions

Abstract

The invention relates to surfactant-free cosmetic, dermatological and pharmaceutical compositions, comprising at least one copolymer consisting essentially of a1) 1 to 50% by weight of the repeat structural unit of the formula (1) 1 where n is an integer from 2 to 9, or a2) 1 to 50% by weight of a mixture of the repeat structural unit of the formula (1) and the repeat structural unit of the formula (2) 2 where R, R1 and R2 may be identical or different and are hydrogen or a linear or branched alkyl or alkenyl group having in each case 1 to 30 carbon atoms and b) 49.99 to 98.99% by weight of the repeat structural unit of the formula (3) 3 in which R3 is hydrogen, methyl or ethyl, Z is (C1-C8)-alkylene, n is an integer from 2 to 9 and X is an ammonium, alkali metal or alkaline earth metal ion and c) 0.01 to 8% by weight of crosslinking structures which originate from monomers having at least two olefinic double bonds.
