    • (A) An anionic surfactant, (B) a silicate monomer and (C) a basic silane are mixed in water or a mixed solvent of a water-miscible organic solvent and water to obtain a mesoporous silica complex having mesopores with a uniform size, the anionic surfactant Component (A) is removed by washing the resultant mesoporous silica complex with an acidic aqueous solution, a water-miscible organic solvent or an aqueous solution thereof to obtain a mesoporous silica outer shell utilizing the structure of the mesoporous silica complex as a template, and the mesoporous silica complex or the mesoporous silica outer shell is calcined to obtain a mesoporous silica. The mesoporous silica can be synthesized in this manner utilizing the anionic surfactant micelle with a remarkably low affinity to the silicate monomer.

    • 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.
