Abstract
A method for producing silica-coated spherical silicone elastomer particles which includes a step in which a tetraalkoxysilane (E) is added to a liquid comprising spherical silicone elastomer particles (A), an alkaline substance (B), one or more ingredients (C) selected from among cationic surfactants and cationic water-soluble polymers, and water (D), and the tetraalkoxysilane is hydrolyzed and condensed to thereby coat the surfaces of the spherical silicone elastomer particles with silica.
