Oily cosmetic composition containing, as a thickener, an association of two copolymers and optionally containing an amphiphilic rheology corrector

Claim 1

A thickened cosmetic composition containing an oil phase and a thickening agent for said oil phase, said thickening agent comprising in combination: (1) a first copolymer consisting essentially of (a) units resulting from the polymerization of an unsaturated ester of a long chain fatty alcohol and (b) units resulting from the polymerization of a monomer selected from the group consisting of unsaturated monocarboxylic acid, unsaturated dicarboxylic acid, monoester of unsaturated dicarboxylic acid, monoamide of unsaturated dicarboxylic acid and unsaturated sulfonic acid, and (2) a second copolymer consisting essentially of (a) units resulting from the polymerization of an unsaturated ester of a long chain fatty alcohol and (b) units having the following formula: ##STR4## wherein M represents --O-- or --NH--, R 1 represents --H or --CH 3 , n is a number ranging from 2 to 20, and R 2 and R 3 , each independently, represent hydrogen or a hydrocarbon having 1-4 carbon atoms, or units resulting from the polymerization of a monomer selected from the group consisting of acrylamide, methacrylamide, N,N-dimethylacrylamide, N-vinylpyrrolidone, and diacetone acrylamide, the weight amount of units 1(a) and 2(a) in said first and second copolymers being at least equal to 50%, and the weight amount of said units 1(b) and 2(b) in said first copolymer and second copolymer being at least equal to 2%.
