ABSTRACT:
The present invention provides new silica composite capsules that can be easily prepared, a composition containing the silica composite capsules, and a transparent gel-form composition excellent in appearance transparency and texture in use, and in particular, a transparent gel-form composition with improved cleansing properties when used as a cleanser. Micelle/silica composite capsules can easily be obtained, in an aqueous system, by mixing a material capable of forming micelles in water and a water-soluble silane derivative having a specific structure in aqueous solution. In addition, emulsion/silica composite capsules wherein the periphery of emulsion particles in the inner phase is coated with silica, can easily be obtained by mixing a surfactant, water, an oil, and a water-soluble silane derivative having a specific structure. Moreover, a transparent gel-form composition showing excellent appearance transparency, the texture in use and cleansing properties, can be obtained by blending a water-soluble silane derivative having a specific structure into the formulation that contains a surfactant, an oil and water, and capable of taking a surfactant association structure with aqueous continuous phase or both of aqueous continuous phase and oil continuous phase in the formulation.
