Zinc carbonate basic (ZnCO₃·2Zn(OH)₂) is a white, odorless powder used in various industrial and pharmaceutical applications. It is commonly employed as an intermediate in the production of zinc-based products, a mild astringent in skincare formulations, and an additive in cosmetics. In addition, it serves as a raw material in the manufacturing of rubber, ceramics, and as a precursor for zinc oxide. Zinc carbonate basic is valued for its chemical stability and its role as a non-toxic, environmentally friendly source of zinc.
