Patent ID: 7465774

Claim:
A cosmetic or pharmaceutical composition, containing as a thickener or dispersant an effective amount of a copolymer obtained by free radical polymerization of A) 75-99.45% by weight of an olefinically unsaturated C 3 -C 5 -monocarboxylic acid, of an olefinically unsaturated C 4 -C 8 -dicarboxylic acid or of its anhydride or a mixture of such carboxylic acids or anhydrides with B) 0.5-24.95% by weight of one or more long-chain compounds with isolated C—C multiple bonds selected from the group consisting of (1) mono- or polyunsaturated C 8 -C 30 -monocarboxylic acids which may have additional hydroxyl groups, as well as their alkali metal and alkaline earth metal salts, alkyl esters, amides, sorbitan esters, glycerol esters or polyglycerol esters, (2) mono- or polyunsaturated aliphatic C 8 -C 30 -amines, and (3) mono- or polyunsaturated C 8 -C 30 -alcohols as well as their esters with saturated C 1 -C 4 -monocarboxylic acids, C) 0-24.45% by weight of other copolymerizable monomers and D) 0.05-5% by weight of one or more compounds with at least two olefinically unsaturated groups in the molecule as crosslinkers.
