    摘要： The invention relates to the use of at least one copolymer obtainable by (i) free-radically initiated copolymerization of a monomer mixture comprising (a) 1 to 99.99% by weight of at least one monomer chosen from N-vinylimidazoles and diallylamines optionally in partially or completely quaternized form; (b) 0 to 98.99% by weight of at least one neutral or basic water-soluble monomer which is different form (a); (c) 0 to 50% by weight of at least one unsaturated acid or unsaturated anhydride, (d) 0 to 50% by weight of at least one free-radically copolymerizable monomer which is different from (a), (b) or (c); and (e) 0.01 to 10% by weight of at least one monomer which acts as crosslinker and has at least two ethylenically unsaturated, nonconjugated double bonds; and (ii) subsequent partial or complete quaternization or protonation of the polymer in the case where the monomer (a) is unquaternized or only partially quaternized, as additive for skin cosmetic and dermatological preparations.

    摘要： A cosmetic composition comprising water-soluble copolymer, which as characteristic structural elements comprises a) vinylcarboxamide units of the general formula I where R1 and R2 independently of one another are H, alkyl, cycloalkyl, aryl or aralkyl, and b) units of the general formula II where A is a chemical bond or an alkylene group, the radicals R3 independently of one another are H, alkyl, cycloalkyl, aryl or aralkyl, or together with the nitrogen atom to which they are bonded, form an unsubstituted, mono- or polysubstituted, five- to seven-membered, heterocyclic, aromatic or nonaromatic ring, which if appropriate contains one or two further heteroatoms, selected from among O, N and S, it being possible for the heterocyclic ring to be fused to a further five- or six-membered, aromatic or nonaromatic ring, R4 is H, alkyl or aralkyl.
