Water-based gel cosmetic compositions containing emulsifier

摘要

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.

主权项

1. 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.
