発明の名称 (英語) PARTICULATE COMPOSITION, LIQUID COMPOSITION, METHOD FOR PRODUCING PARTICULATE COMPOSITION, SURFACE MODIFYING AGENT, AND METHOD FOR IMPROVING WATER DISPERSIBILITY
発明の概要(英語) Provided are: a particulate composition which exhibits high dispersibility in water regardless of the kind of solid particles; and a method for producing this particulate composition. Also provided are: a liquid composition; a surface modifying agent; and a method for improving water dispersibility. The present invention additionally provides: a particulate composition which has dispersibility in an oil-based material; and a method for producing this particulate composition. A particulate composition according to the present invention contains solid particles and an amphiphilic substance that is present on the surfaces of the solid particles; and the amphiphilic substance has an ability of forming closed vesicles in water. A method for producing a particulate composition according to the present invention comprises: a step for preparing a mixture of solid particles and a solvent in which amphiphilic substance that has an ability of forming closed vesicles in water is dissolved; and a step for removing the solvent in the mixture.
従来技術、競合技術の概要(英語) BACKGROUND ART
The solid particles, such as paints or cosmetics have been used in many applications, the solid particles, dispersed in water medium such as a uniform and stable than the conventional technique has been demanded. In particular, for foundation cosmetic as the color pigment particles in the UV or the like delicate conditions of a variety of dispersion stability is demanded.
For example, to Patent Document 1, the silicone resin and/or solid particles from the surface of the organic powders, a water-soluble polyoxyalkylene glycol derivatives, water-soluble cationic polymer, low molecular weight organosilicon derivatives in the treatment for hydrophilicity, to improve the dispersibility of the water is disclosed.
