Title:
SURFACE MODIFIED INORGANIC OXIDE FINE PARTICLES, AND SUNSCREEN COSMETIC MATERIAL CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2013/161553
Kind Code:
A1
Abstract:
Provided are: surface modified inorganic oxide fine particles that maintain the properties of inorganic oxide fine particles such as transparency, ultraviolet light shielding properties, weather resistance, light discoloration resistance, and the like while contributing to water dispersibility; a method for manufacturing the surface modified inorganic oxide fine particles; and a sunscreen cosmetic material that contains the surface modified inorganic oxide fine particles. These surface modified inorganic oxide fine particles are inorganic oxide fine particles with an average particle diameter of 200 nm or less, wherein the surface is modified by a base having a polyglycerin chain. The inorganic oxide is preferably titanium oxide, silicon oxide, aluminum oxide, zirconium oxide, or zinc oxide.
