发明名称 SURFACE MODIFIED INORGANIC OXIDE FINE PARTICLES, AND SUNSCREEN COSMETIC MATERIAL CONTAINING SAME
摘要 Provided are surface-modified inorganic oxide fine particles that are added with water dispersibility while maintaining properties of inorganic oxide fine particles, such as transparency, ultraviolet blocking ability, weatherability, and photodiscoloration resistance; a method for producing the surface-modified inorganic oxide fine particles; and a sunscreen cosmetic containing the surface-modified inorganic oxide fine particles.;The surface-modified inorganic oxide fine particles include inorganic oxide fine particles having an average particle size of 200 nm or less; and a group containing a polyglycerol chain and modifying surfaces of the particles. The inorganic oxide is preferably selected from titanium oxides, silicon oxides, aluminum oxides, zirconium oxide, and zinc oxide.
