    • 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)  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)  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)  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.
    • 本发明涉及无表面活性剂的化妆品,皮肤病学和药物组合物,其包含至少一种基本上由以下组分组成的共聚物:a)1至50重量%的式(1)的重复结构单元,其中n为2至9的整数, ora2)1至50重量%的式(1)的重复结构单元和式(2)的重复结构单元的混合物,其中R,R 1和R 2可以相同或不同 并且是氢或在每种情况下具有1至30个碳原子的直链或支链烷基或烯基,和b)式(3)的重复结构单元的重量的49.99至98.99%,其中R 3是氢,甲基 或乙基,Z是(C 1 -C 8) - 亚烷基,n是2至9的整数,X是铵,碱金属或碱土金属离子,和c)0.01至8重量%的源自具有 至少两个烯属双键。
