Fluorphlogopite Mica (Synthetic Mica) for cosmetic
Specifications
1.High purity >98
2.Small content of iron (<0.1)
3.High surface smoothness
(surface roughness of 10 nm period)
4.Uniform si
Synthetic mica powder is produced by processing fluorine gold synthetic mica through immersing,Stripping,wheel grinding, beating, grading, washing, sedimentation, grading, drying. Synthetic mica powder can be divided into three major products: pearl grade wet synthetic mica powder, cosmetic grade wet synthetic mica powder, filler synthetic mica grade wet.
Cosmetic grade wet synthetic mica powder has the performances of high purity, strong adhesion, feel fine, and there is a sense of velvet ears, non-toxic, anti-oxidation . Mainly used for the production of high-end cosmetics.
