Title:
METHOD FOR PRODUCING COMPOSITE PARTICLE, METHOD FOR PRODUCING COSMETIC, AND COSMETIC
Document Type and Number:
WIPO Patent Application WO/2013/018356
Kind Code:
A1
Abstract:
The present invention provides a method for producing a composite particle, wherein a compound selected from an alkoxy silane, a silanol group-containing silane, and a partial condensate of them is added into a mixed solution obtained by blending, at least, a mixed aqueous disperse solution in which an inorganic powder and a silicone elastomer are dispersed, a cationic water-soluble polymer, and an alkaline substance, whereby carrying out a hydrolysis-condensation reaction to produce a composite particle formed of the inorganic powder whose surface is adhered with the silicone elastomer by using a silicone resin as a binder. There can be provided a method for producing, regardless of the kind of inorganic powders, a composite particle in which a silicone elastomer is adhered uniformly onto surface of an inorganic powder.
