Production manner of micellar - silica compound capsule content water system transparent constituent, and production manner of emulsion - silica compound capsule content transparent constituent

摘要

P To provide a new method for preparing a new silica composite capsule with ease and to provide a composition comprising the silica composite capsule. PSOLUTION: The micelle-silica composite capsule, in which the periphery of the micelle is covered with silica and is easily prepared in aqueous solution by mixing a substance capable of forming micelle in water with a water-soluble silane derivative represented by following general formula (1). By mixing a surfactant, water, an oil and a water-soluble silane derivative represented by following general formula (1), the emulsion-silica composite capsules can be easily obtained in which the emulsion particles as the inner phase are surrounded with the silica. Formula (1); Si- (ORSP1/SP) SB4/SB, (in the formula at least one of RSP1/SPis a residue of a polyhydric alcohol and the rests are optionally an alkyl group). PCOPYRIGHT: (C)2008 and JPO& INPIT
