Calamine Powder
What is Calamine Powder?
Calamine powder is a fine mineral-based ingredient primarily composed of zinc oxide, with at least 98% purity, lightly colored pink by ferric oxide. Sourced from natural zinc and iron ores, it belongs to the category of skin protectants and opacifying agents in cosmetics. Typically used in lotions, creams, suspensions, and dry powders, it functions by creating a thin, breathable physical barrier on the skin surface. This barrier helps shield against external irritants and absorbs excess moisture from weepy or oozing areas. Its mild astringent properties come from the zinc oxide, which tightens skin proteins, while the ferric oxide provides a subtle tint to blend with skin tones and offer visual coverage over redness. In formulations, it imparts a smooth, matte finish without clogging pores.
