摘要:
A method for producing silicone fine particles is provided. The particle comprises a spherical fine silicone elastomer particle and polyorganosilsesquioxane particles attached to the surface of the spherical fine silicone elastomer particle. The polyorganosilsesquioxane particle has a particle size of 200 to 2,000 nm which is smaller than the spherical fine silicone elastomer particle. The method comprises the steps of adding an organotrialkoxysilane to water for hydrolysis, and adding spherical fine silicone elastomer particles having a volume average particle size of 0.5 to 100 µm, an anionic surfactant, and an alkaline substance to the organotrialkoxysilane hydrolysate and allowing the mixture to stand to thereby promote condensation of the organotrialkoxysilane hydrolysate so that the polyorganosilsesquioxane is deposited on the surface of the spherical fine silicone elastomer particles.
