Abstract:
A cosmetic composition is provided which includes composite particles of a sunscreen agent and a condensation polymerized polyamide binder, a water-insoluble powdered polymer of porous particles having an Oil Absorbance (castor oil) Value ranging from about 90 to about 500 ml/100 gm, and a cosmetically acceptable carrier. The composition exhibits an excellent soft focus property to hide skin imperfections, and retains relatively high SPF photoprotection.
