Description

Bacitracin Zinc CAS NO 1405-89-6 is a zinc salt complex of the polypeptide antibiotic bacitracin. This compound is valued for its potent antibacterial activity, particularly against Gram-positive bacteria, and its stability in topical formulations. It is a critical active pharmaceutical ingredient (API) for manufacturers in the pharmaceutical and veterinary sectors requiring a reliable, high-purity antimicrobial agent.

Application

• Topical Antibiotic Ointments and Creams: Primary use in human and veterinary medicine for preventing and treating superficial skin infections, cuts, and burns.
• Veterinary Medicinal Products: Key ingredient in wound sprays, udder creams, and ophthalmic preparations for livestock and companion animals.
• Pharmaceutical Combination Products: Used alongside other antibiotics (e.g., neomycin, polymyxin B) in broad-spectrum topical formulations.
• Animal Feed Additive: Employed as a growth promoter and for the prevention of certain bacterial enteric diseases in livestock, where regulations permit.
• Preservative in Cosmeceuticals: Acts as an antimicrobial agent in select cosmetic and personal care products to ensure shelf-life stability.
