Method of manufacturing an ultraviolet shielding composite particles and the ultraviolet shielding composite particle containing dispersion and the aqueous dispersion and oil dispersion and the cosmetic

摘要

The ultraviolet shielding composite particles of the present invention is an ultraviolet shielding composite particles of 5μm or less and 0.05μm average particle size which comprises a metal oxide particles having ultraviolet screening ability and the organic ultraviolet absorber in the resin , average particle diameter of 0.1μm and less than 0.003μm and include one or more selected from the group consisting of zinc oxide, titanium oxide, cerium oxide, iron oxide, metal oxide particles, the composite particles 80 mass% and 0.1 mass% or more, the content of the metal oxide particles is 80 mass% and 1 mass% or more, the content of the organic ultraviolet absorber in the ultraviolet shielding metal oxide particles I have distributed in the composite particles. According to the ultraviolet shielding composite particles, it is possible to prevent deterioration of cosmetics, discoloration and deterioration of feeling organic ultraviolet absorber is recrystallized by the influence of metal ions.
