Cosmetic composition containing as thickener a polymer with a low proportion of units with ionic groups

Abstract

Abstract Cosmetic composition or cosmetic composition vehicle in the form of a thickened emulsion of the water-in-oil type. The thickener consists of a copolymer comprising: units of formula I <IMAGE> where M is an oxygen atom or a group -N(R3)-, R1 represents -H or -CH3, R2 is a saturated hydrocarbon chain, R3 represents -H or a saturated hydrocarbon chain, and units of formula II <IMAGE> in which: either R4 represents -H or -CH3, and R5 then represents -CO-XZ-Y, sulphur-containing or carboxylated ester or amide), or R4 represents -H and R5 then represents -SO3H, -CH2SO3H or -C6H4-SO3H, on the understanding that the abovementioned copolymer contains, in units, from 90 to 99% of units of formula I, the other units consisting of the units of formula II, and that the abovementioned -COOH, -SO3H, -CH2SO3H and -C6H4SO3H groups present are in partially or totally salified form, and on the understanding that when R5 represents -C6H4SO3H, M represents a group -N(R3)-
