Abstract
Silicone composite particles are provided in which silicone elastomer spherical particles having a volume average particle size of 0.1-100 μm are coated with an organosilsesquioxane-based silicone resin containing inorganic nano-particles having a volume average particle size of up to 100 nm. The silicone composite particles are compounded in a cosmetic composition to exert a UV screening effect or bactericidal property inherent to inorganic nano-particles and to impart a pleasant feel on use. A preparing method and a cosmetic composition are also provided.
