Description

Calamine is a time-tested medicinal powder primarily composed of zinc oxide and a small amount of ferric oxide, widely recognized for its soothing and protective dermatological properties. Its core value lies in its ability to provide safe, effective, and non-irritating topical relief for a variety of minor skin conditions. This essential material is a critical component for manufacturers in the pharmaceutical, over-the-counter (OTC) healthcare, and personal care industries seeking to formulate trusted skin protectants and anti-pruritic products.

Application

• OTC Skin Protectants: Key component in formulations designed to relieve itching, pain, and discomfort from poison ivy, oak, sumac, and minor burns.
• Dermatological Cosmetics: Used in medicated cosmetics and face powders for its soothing effect and subtle skin-toning properties.
• Veterinary Care Products: Incorporated into topical preparations for animals to treat skin irritations and promote healing.
