Fluormicas have been synthesized by an internal resistance electric melting method. Because of their sizes and stable structures of the crystals those synthetic micas had a potential for cosmetic use. In them, synthetic fluorphlogopite(FPG)has been studied to be the best mica for cosmetics.The fluorphlogopite is chemically pure, and has a excellent lubricity and adhesiveness. The authors established the methods of its synthesis and pulverizing for cosmetic use. UV absorption is the most important item for cosmetics for e.g. protecting sunburn and suntan. The authors newly developed a method to synthesize an iron-rich fluorphlogopite which is more efficient to absorb UV-rays than common fluorphlogopite. It has presently been used in some commercial cosmetics.
