摘要

Cosmetic, dermatological and/or pharmaceutical agent containing copolymer A with 1-50 %, by weight N-vinylcaprolactam units, 49.99-98.99 %, by weight units derived from acrylamido- or (m)ethacrylamido-alkane-sulfonic acid(s) as lithium, sodium, potassium, magnesium, calcium, aluminum or (substituted) ammonium salt and 0.001-8, preferably 0.01-5 %, by weight crosslinked structures derived from monomers with at least 2 olefinic double bonds. Cosmetic, dermatological and/or pharmaceutical agent contains copolymer A with 1-50 %, by weight N-vinylcaprolactam units, 49.99-98.99 %, by weight units of formula (1), derived from acrylamido- or (m)ethacrylamido-alkane-sulfonic acid(s) as lithium, sodium, potassium, magnesium, calcium, aluminum or (substituted) ammonium salt, and 0.001-8, preferably 0.01-5 %, by weight crosslinked structures derived from monomers with at least 2 olefinic double bonds: [Image] R 1>H, methyl or ethyl; Z 11-8 C alkylene; X +>Li +>, Na +>, K +>, Mg 2>+>/2, Ca 2>+>/2, Al 3>+>/3, NH 4+>, mono-, di-, tri- or tetra-alkylammonium, in which the alkyl substituents are selected from 1-22 C alkyl or 2-10 C hydroxyalkyl or mono- to tri-ethoxylated ammonium compounds with the same or different degrees of ethoxylation.
