SILICA COMPOSITE CAPSULES OBTAINED WITH WATER-SOLUBLE SILANE DERIVATIVE, COMPOSITION CONTAINING THE SAME, AND TRANSPARENT GEL-FORM COMPOSITION

摘要

Novel silica composite capsules which can be easily produced; a composition containing the silica composite capsules; and a transparent gel-form composition which is excellent in appearance transparency and use feeling, especially a transparent gel-form composition which has improved cleaning ability when used as a cleaning preparation. A substance capable of forming micelles in water is mixed in an aqueous solution with a water-soluble silane derivative having a specific structure. Thus, micelle/silica composite capsules are easily obtained in an aqueous system. By mixing a surfactant, water, an oil, and a water-soluble silane derivative having a specific structure, emulsion/silica composite capsules can be easily obtained in which the emulsion particles as the inner phase are surrounded with the silica. Furthermore, by incorporating a water-soluble silane derivative having a specific structure into a composition capable of giving a surfactant association structure in which water constitutes a continuous phase or both water and an oil each constitutes a continuous phase, a transparent gel-form composition is obtained which is excellent in appearance transparency, use feeling, and cleaning ability.
