1. Cosmetic-grade sericite powder (Sericite) is a kind of natural fine-grained muscovite, which belongs to the layered structure of silicate. It belongs to monoclinic crystal (the crystal chemical formula is: K0.5-1(Al,Fe,Mg)2(SiAl)4O10 (OH) 2·nH2O, the crystal is scaly with silky luster. The natural composition of sericite and its unique structure give it soft touch, soft-focus luster, good affinity, strong skin adhesion, etc. It has a soft texture and good ductility compared with mica.
2. Cosmetic-grade mica powder (Mica) is a soft base material made of fine natural mica wafers, processed by wet milling and grading technology. The product feels delicate and smooth, silky and soft, and has a good skin affinity. The natural texture makeup formed produces a fresh, bright, transparent and shiny effect. Compared with sericite, it has a relatively higher gloss.
