Calamine contains which components?

Explanation:
Calamine is a combination of zinc oxide with a pigment, ferric oxide. The zinc oxide provides soothing, protective, and mild astringent effects that help calm irritated skin. The ferric oxide is the pink pigment that colors calamine; it doesn’t add therapeutic action but defines the familiar pink appearance of calamine preparations. Titanium dioxide would be a white pigment, not characteristic of calamine, and zinc oxide alone would lack the pink coloring provided by ferric oxide.
