る。The present inventors have paid attention to this point, and as a result of a series of basic studies, the present inventors have contained an iron element which has never been used as a base material for composite mica powder. The present inventors have found that a composite mica powder that uses a synthetic mica powder as a base material has a composite function that satisfies all the above-mentioned required properties, and has reached the present invention. The present invention provides the synthetic mica powder containing iron elements, titanium oxide, cerium oxide, zinc oxide, silicon dioxide, one or more selected from aluminum oxide and <br/> zirconium arm or Ranaru group It is a composite mica powder coated with the oxide of

線遮断率を示す。 The composite mica powder of the present invention is substantially white when dried, but has the property of changing to a skin color close to the skin color when wet with a liquid. Since human skin has moisture, when this composite powder is applied to the skin, it develops a color approximately the same as the color of the skin. Therefore, this composite powder is particularly suitable for cosmetics. It should be noted that the term “approximately white when dried” means that the color is white or slightly reddish when dried. Titanium oxide, cerium oxide and the composite mica powder coated with one or more zinc oxide, especially composite mica powder coated with titanium oxide is not seen at all in the conventional mica powder and composite mica powder excellent Has a UV blocking effect. That is, the conventional composite mica powder having the synthetic mica containing no iron element as the base material showed only about 60% of the ultraviolet ray blocking rate as described in the comparative example below, but the composite mica powder of the present invention Indicates an ultraviolet ray blocking ratio of 93 % or more as described in Examples below.
