(57) [Summary] (Modified) [Composition] The cosmetic pigment is an anhydrous metal oxide in which the water of crystallization contained in the clay mineral is dehydrated and the particle surface of the clay mineral is integrated with the clay mineral. It is characterized in that it is coated with a substance, and the cosmetic is blended with this cosmetic pigment. Such a cosmetic pigment is obtained by adding a metal compound to the clay mineral in the form of a slurry, precipitating a hydrous metal oxide on the particle surface of the clay mineral by a chemical reaction to coat the clay mineral, and 500 after washing and filtering the clay mineral coated with metal oxide It is manufactured by firing at 1 to 1100 ° C. [Effect] Since the anhydrous metal oxide coating the surface of the clay mineral particles is integrated with the clay mineral, it is not easily separated, has a high ultraviolet absorption power, and is unlikely to cause makeup scraping or dullness. Further, by coating a clay mineral having a strong surface activity with a metal oxide, it is stable against other compounding ingredients of cosmetics. |
