Abstract:
The present invention relates to a topical cosmetic composition that has improved non-oily feel comprising: (a) a hybrid silicone composite powder having a spherical shape with particle diameter ranging from 2 to 10 μm, of which each particle has a composite structures consisting of two interpenetrating polymer networks of polydimethylsiloxane (PMS) and polymethylsilsesquioxane (PMSQ). These two interpenetrating polymer networks are joined together by physical entanglements instead of chemical bonds; (b) a volatile cosmetic fluid; (c) a silicone fluid with viscosity ranging from 2 to 350 cSt; (d) an oil base consisting of an oil, wax, oil gelling agent or the mixture thereof; (e) a surface active agent; (f) a cosmetic pigment; and (g) an optional aqueous gel containing glycerin, glycols and an aqueous thickening agent. The cosmetic composition provides an improved skin sensory feel and a superior matte finish, and is useful for skin treatment, makeup and personal hygiene products.
