COMPOSITE PIGMENT COATED WITH TITANIUM DIOXIDE, METHOD FOR PRODUCING SAME, AND COSMETIC COMPOSITION CONTAINING SAME

WIPO Patent Application WO/2017/065481

A1

The present invention relates to a composite pigment coated with titanium dioxide, a method for producing the same, and cosmetics containing the same, wherein the composite pigment is prepared by the steps of: performing first surface treatment on a pigment by hydrolyzing titanium dioxide precursor titanium tetrachloride (TiCl4) thereon so that a uniform coating surface is formed thereon; performing second surface treatment on the first surface-treated pigment by hydrolyzing titanium dioxide precursor titanium tetrachloride (TiCl4) thereon and stirring the same after the hydrolysis ends so that a non-uniform coating surface is formed thereon; and completing a composite pigment coated with titanium dioxide (TiO2) by firing the second surface-treated pigment and converting TiO(OH)2 to TiO2. The composite pigment according to the present invention has an effect of obtaining a soft brilliance effect and hiding power suitable for skin, since the composite pigment has a glossiness of 30-35 which is lower than that of a general pearlescent pigment of 40-45, and has a hiding power (HAZE value) of 70-80 which is higher than that of the general pearlescent pigment of 50-60.
