ABSTRACT:
A cosmetic water-in-oil emulsion composition is provided which includes composite particles of a sunscreen agent and a condensation polymerized polyamide binder, an emulsifying silicone surfactant sufficient to form the water-in-oil emulsion, an oil phase, and a water phase. The composition exhibits relatively high SPF photoprotection while maintaining excellent soft focus properties that hide skin imperfections.
