Calamine

Calamine (CAS 8011-96-9) is a mineral-based mixture of zinc oxide and ferric oxide, available under pharmacopoeial designations including Calamine IP, Calamine BP, and Calamine USP. It carries no assigned E-code and is classified within the salts and minerals category for industrial and pharmaceutical applications.

In pharmaceutical topical formulations, calamine acts as a mild astringent and skin protectant by forming a thin barrier that reduces moisture loss and soothes irritated tissue. In personal care products such as lotions and powders, the zinc oxide component provides pH-buffering action, helping to maintain formulation stability and skin surface acidity within target ranges.

Calamine is sourced in pharmaceutical-grade powder form compliant with BP, USP, and IP monograph specifications, ensuring controlled iron oxide content and particle consistency. Suppliers operating under REACH regulations provide full compliance documentation. Packaging is typically available in multi-kilogram bags suited to industrial procurement volumes.
