Mica pearlescent pigment is a kind of sandwich compound formed by depositing metal oxide (titanium dioxide or iron oxide) on natural mica flakes. The main components of mica and titanium and iron oxides are all determined after repeated experiments and use. For the production of special pearlescent pigments for cosmetics, the raw materials used are carefully selected. For mica or other substrates, heavy metal detection is first carried out. Only materials that meet the standards can be used for cosmetic pigment production; for other raw materials, high-purity reagents or food-grade raw materials are used. Therefore, the safety of the products produced is guaranteed, and the products must also undergo rigorous testing. In addition, in the production process of pearlescent pigments, in order to enrich the color spectrum of pearlescent pigments and make pearlescent pigments more vivid, organic pigments are sometimes used to coat pearlescent pigments to produce pearlescent pigments with bright appearances. As we all know, the use of organic pigments in cosmetics has very large limitations. Only a very small number of organic pigments can be used in cosmetic production, and can only be used in areas other than the eyes and lips. Therefore, the use of organic pigments to produce pearlescent pigments for cosmetics is Very inappropriate. The pearlescent pigments for cosmetics that are currently produced are all produced from the materials in the INCI catalog that can be used on the parts of the human body, most of which are inorganic materials, and a small amount of natural pigments are used.
