MANUFACTURING METHOD OF AQUEOUS DISPERSIONS CONTAINING TITANIUM DIOXIDE AND ZINC OXIDE AND COSMETIC COMPOSITION FOR PROTECTING CONTAINING THEREOF

摘要

The present invention relates to a process for preparing an aqueous dispersion of an inorganic UV-blocking agent and a cosmetic composition containing the UV-ray-blocking agent, and more particularly to a preliminary dispersion step of adding an inorganic UV-blocking agent to a dispersion medium and a dispersion medium-And dispersing the wetted water dispersion using a continuous bead mill of 0.05 to 5 mm, wherein the inorganic ultraviolet screening agent is titanium dioxide, zinc oxide or a mixture thereof, and the dispersant is polyglyceryl-And the dispersion medium is purified water.According to the present invention, it is possible to overcome disadvantages such as feeling of use and whitish appearance when titanium dioxide or zinc oxide itself is used as cosmetics such as hydrophilic type bibby cream, suncare, foundation and white cream. In addition, when the aqueous dispersion of titanium dioxide or zinc oxide according to the present invention is contained in the cosmetic composition, there is a useful effect that the ultraviolet ray blocking effect, stability and usability are excellent.;
