Cosmetic composition with a fixing and/or conditioning polymer containing a specific acrylic copolymer

A cosmetic composition comprising, in a cosmetically acceptable aqueous or aqueous/alcoholic medium,

• at least one acrylic copolymer formed from (a) approximately 35 to 75% by weight of an alkyl acrylate, (b) approximately 25 to 65% of alkyl methacrylate and (c) 1 to 15% of at least one ethylenic carboxylic acid having from 3 to 5 carbon atoms, the alkyl radicals having from 1 to 5 carbon atoms and the percentages being expressed with respect to the total weight of the copolymer, and
• at least one polymer selected from a fixing polymer and a conditioning polymer, wherein the ratio by weight of the at least one fixing and/or conditioning polymer to the at least one acrylic copolymer is from 0.1:1 to 10:1;
• wherein the at least one polymer selected from a fixing polymer and a conditioning polymer is a crotonic acid/vinyl acetate/vinyl neododecanoate terpolymer;
• and
• with the proviso that the fixing or conditioning polymer is not selected from a polyvinylpyrrolidone/vinyl acetate (PVP/VA) copolymer.
