ORGANIC-INORGANIC COMPOSITE PARTICLES AND PROCESS FOR PRODUCTION THEREOF, DISPERSION CONTAINING THE PARTICLES, AND COSMETIC CONTAINING THE PARTICLES |
摘要 |
The present invention relates to organic-inorganic composite particles, a process for producing the same, a dispersion containing the particles, and a cosmetic containing the particles. Organic-inorganic composite particles comprising inorganic oxide particles each of which has a cationic charge on the particle surface and polymer gel molecules which are derived from a natural substance, have an anionic functional group and one or more hydroxyl groups in a molecule and have both of shrinking and swelling property, said polymer gel molecules being electrostatically bonded to surfaces of the inorganic oxide particles; a process for producing the particles; a dispersion containing the particles; and a cosmetic containing the particles. These organic-inorganic composite particles have good dispersibility not only in aqueous solvents such as water but also in non-aqueous solvents and further have characteristics that aggregation of the particles scarcely occurs. |
