Abstract
Disclosed are water-based cosmetic compositions comprising a synthetic non-associative thickening polymer, a synthetic associative thickening polymer, an emulsifier, a film forming polymer, and a liquid fatty substance. The ratio of the synthetic non-associative thickening polymer to the synthetic associative thickening polymer is greater than 1:1, or alternatively, said ratio is less than or equal to 1:1.
Claims31
A water-based gel cosmetic composition comprising:
- (a) a viscosity increasing system comprising (I) at least one synthetic non-associative thickening polymer comprising acryloyldimethyltaurate;
- and (II) at least one synthetic associative thickening polymer selected from the group consisting of ammonium acryloyldimethyltaurate/steareth-8 methacrylate copolymer, ammonium acryloyldimethyltaurate/laureth-7 methacrylate copolymer, and mixtures thereof;
- (b) at least one emulsifier selected from the group consisting of glycerol esters, oxyalkylenated esters, gemini surfactants, and mixtures thereof;
- (c) at least one film forming polymer;
- (d) at least one liquid fatty substance;
- (e) water;
- (f) optionally a pigment;
- and
- (g) optionally at least one wax;
- wherein the composition has a viscosity at 25° C. of from about 2,000 Pa·s to about 90,000 Pa·s at low shear rate.
