Description

Bacitracin is a polypeptide antibiotic complex produced by certain strains of *Bacillus subtilis* and is a critical active pharmaceutical ingredient (API) for combating gram-positive bacterial infections. Its primary commercial value lies in its potent bactericidal activity, which is essential for formulating topical ointments, veterinary medicines, and as a growth promoter in animal feed. This product is indispensable for manufacturers in the pharmaceutical, veterinary, and animal nutrition industries seeking a reliable and high-purity antibiotic source for their formulations.

Application

• Pharmaceutical Formulations: Key ingredient in topical antibiotic ointments, creams, and powders for human use, often combined with other antibiotics like neomycin and polymyxin B.
• Veterinary Medicine: Used in ointments, sprays, and injectables for the treatment of skin, eye, and wound infections in livestock and companion animals.
• Animal Feed Additive: Employed as a growth-promoting antibiotic in poultry and swine feed to improve feed efficiency and prevent disease.
• Microbiological Research: Serves as a selective agent in culture media for the isolation and identification of specific bacterial strains in laboratory settings.
• Preservative Systems: Can be utilized in certain cosmetic and personal care products for its antimicrobial properties.

Quality Control

Our Bacitracin is manufactured and tested to meet stringent quality standards appropriate for pharmaceutical and feed-grade applications. We ensure compliance with relevant pharmacopoeial monographs, including USP (United States Pharmacopeia) and EP (European Pharmacopoeia), where applicable. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, potency, and impurity profiles, available upon request to guarantee traceability and regulatory compliance for our global B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term stability, consider storage under inert atmosphere conditions.
