PROBLEM TO BE SOLVED: To provide a new method for preparing a new silica composite capsule with ease and to provide a composition comprising the silica composite capsule. SOLUTION: The micelle-silica composite capsule, in which the periphery of the micelle is covered with silica, 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-(OR<SP>1</SP>)<SB>4</SB>, (in the formula at least one of R<SP>1</SP>is a residue of a polyhydric alcohol and the rests are optionally an alkyl group). COPYRIGHT: (C)2008,JPO&INPIT |
