Can mica be used in skin care products?
Mica is a rock forming mineral with six square crystalline forms. One of the main rock forming minerals. Characterized by insulation, high temperature resistance and industrial use, sericite is widely used in coatings, paints, electrical insulation and other industries.
Mica is a general term for mica group minerals. They are potassium, aluminum, magnesium, iron, lithium and other metal silicate. They are layered structures and monoclinic systems. The crystals are false, six - side, flaky or plate-like, sometimes columnar. The layered cleavage is very complete and has a glassy luster, and the flakes are elastic. The refractive index of mica increases with the increase of iron content, and can rise from low positive to middle protuberance. An iron free variety; colorless in flakes; the more iron, the deeper the color; and the increased colour and absorbency.
Some cosmetics contain mica. Mica gives a sparkle to the face
