Description

Bismuth Subgallate is a fine, odorless, yellow powder with astringent and antiseptic properties. It is a key active pharmaceutical ingredient (API) and excipient valued for its ability to control minor bleeding and provide a protective coating on mucosal surfaces. This compound is essential for manufacturers in the pharmaceutical and personal care industries seeking reliable, high-purity raw materials for topical formulations.

Application

• Pharmaceuticals: Primary active ingredient in over-the-counter (OTC) hemorrhoid creams, ointments, and suppositories for its astringent and protective effects.
• Wound Care: Used in medicated powders and topical antiseptics to promote drying and provide a mild protective barrier for minor skin irritations and wounds.
• Cosmetics & Personal Care: Incorporated into certain skin protectant formulations, deodorants, and specialty cosmetic products for its absorbent and mild antiseptic qualities.
• Veterinary Medicine: Applied in topical preparations for animals to address minor skin conditions and as a wound dressing aid.
• Chemical Synthesis: Serves as a precursor or intermediate in the synthesis of other bismuth-containing compounds for specialized applications.
