Abstract
The present invention provides a silicone microparticle, wherein the silicone microparticle comprises 100 parts by mass of a silicone elastomer spherical microparticle having volume-average particle diameter of 0.1 to 100 μm and 0.5 to 25 parts by mass of a polyorganosilsesquioxane to cover surface of the silicone elastomer spherical microparticle, wherein the polyorganosilsesquioxane has a shape of granule with the size thereof being 60 nm or less. There can be provided a silicone microparticle having low agglomerating tendency and excellent dispersibility even if rubber hardness of a silicone elastomer microparticle is low and a particle diameter thereof is small.
