Cosmetic composition with a silicone elastomer and a thickening polymer in the latex form

摘要

Polymeric thickeners for silicone-based cosmetic compositions comprise inverse, auto-invertible latices containing oil and water phases, emulsifier(s) and branched or crosslinked polyelectrolytes comprising (i) homopolymers of weak acid monomers and/or (ii) copolymers of strong acid monomers with neutral or weak acid monomers (both partly or completely neutralised). Cosmetic compositions containing (a) silicone elastomer(s) and (b) polymeric thickener(s) in the form of an inverse, auto-invertible latex containing an oil phase, an aqueous phase, an oil-in-water emulsifier and branched or crosslinked polyelectrolyte(s) comprising (i) homopolymers of weakly acid monomers (partly or completely neutralised) and/or (ii) copolymers of strongly acid monomers with neutral or weakly acid monomers, all in a suitable cosmetic vehicle.
