ABSTRACT:
The present invention concerns synthetic mica powder containing from 75 to 99% of the stoichiometrical composition of fluorine and/or having a shape in which the end face of a particle is laminated, a process for producing such synthetic mica powder, as well as cosmetics having synthetic mica powder blended therewith, in which the synthetic mica powder shows no leaching of fluorine ions and/or improved hold of oils due to lamination at the surface of the powder. Accordingly, in this invention, cosmetics excellent in extensibility, gloss, adherence and moldability, having an appearance of high chroma and of high stability and safety can be obtained.
