Cosmetic make-up compositions comprising an insoluble polymeric material in an aqueous emulsion and an alkyl- or alkoxy-dimethicone copolyol having general formula (I) wherein X is a hydrogen atom or a C1 to C16 alkyl, alkoxy or acyl radical, Y is C8-C22 alkoxy or alkyl radical, n = from about 0 to about 200, m = from about 1 to about 40, q = from about 1 to about 100, the molecular weight of the residue (C2H4O-)x(C3H6O-)yX being from about 250 to about 2000, x and y being selected so that the weight ratio of the oxyethylene/oxypropylene groups is from about 100:0 to about 20:80. The compositions exhibit improved wear and water resistance and are removable with soap and water.
