Abstract: 1. A copolymer obtained by free-radical copolymerization of an alkyl acrylate or methacrylate, a neutral nitrogen-containing water-soluble monomer, a monomer containing cationic groups, and an olefinically unsaturated carboxylic acid of 3 or 4 carbon atoms, characterized in that it is obtained by free-radical copolymerization of a) 20 to 75% by weight of ethyl, n-butyl, tert.-butyl or lauryl acrylate or methacrylate or mixtures thereof, b) 5 to 50% by weight of N-vinylpyrrolidone, N-vinylcaprolactam or mixtures thereof, c) 1 to 25% by weight of N-vinylimidazole, 1-vinyl-2-methylimidazole or mixtures thereof, and d) 1 to 25% by weight of acrylic acid or methacrylic acid, and has a Fikentscher K value of from 15 to 75, measured in ethanol at 25 degrees C.

Abstract: Readily water-soluble, slightly hygroscopic terpolymers which consist of (a) from 10 to 40% by weight of vinylpyrrolidone, (b) from 20 to 50% by weight of vinyl acetate (VAc) or vinyl propionate and (c) from 10 to 40% by weight of hydroxyethyl acrylate, hydroxypropyl acrylate or hydroxyethyl methacrylate, which terpolymers are used as auxiliaries in the cosmetics and pharmaceuticals sectors.

Abstract: Compounds of the formula I I where the individual radicals R are identical or different and are each hydrogen, an alkali metal, or ammonium which is unsubstituted or substituted by organic radicals, or are each C1-C20-alkyl or a polyoxyethylene radical which contains from 1 to 10 ethylene oxide units and whose terminal OH group may be etherified by an alcohol of 1 to 3 carbon atoms, are used as sun screen agents.
