Product Application of Calamine CAS#8011-96-9
Calamine is a well-established active ingredient primarily used in dermatological topical preparations. It is widely formulated into calamine lotion, creams and ointments to soothe itchy, irritated skin, relieve mild rashes, insect bites and minor sunburn. Thanks to its astringent and protective properties, it forms a gentle film on the skin surface to reduce exudation and discomfort.
It is also adopted in mild personal care products for sensitive skin, helping calm transient redness. In pharmaceutical manufacturing, it serves as a functional excipient for external formulations. It is only intended for external use and not suitable for oral administration. Its stable performance makes it a preferred raw material for cosmetic and pharma factories producing skin-soothing products.
