Description

Bacitracin Methylene Disalicylate is a stable, water-soluble complex of the polypeptide antibiotic bacitracin. This formulation is critical for enhancing the stability and bioavailability of bacitracin, making it suitable for various commercial and therapeutic applications. It is primarily sought by manufacturers in the animal feed, veterinary pharmaceutical, and topical antimicrobial product industries for its broad-spectrum antibacterial activity against Gram-positive organisms.

Application

• Animal Feed Additive: Used as a growth promoter and for the prevention of certain bacterial enteritis in poultry and livestock.
• Veterinary Pharmaceuticals: A key active ingredient in ointments, powders, and injectables for treating topical and systemic bacterial infections in animals.
• Topical Antimicrobial Preparations: Formulated into creams, ointments, and wound dressings for human and veterinary use to prevent or treat skin infections.
• Aquaculture: Employed in fish and shrimp farming to control bacterial diseases and improve yield.
• Preservative Systems: Can be used in specific cosmetic or topical product formulations requiring antimicrobial protection.
• Research & Development: Serves as a standard or active component in microbiological and pharmaceutical research.

Quality Control

Our Bacitracin Methylene Disalicylate is manufactured and tested to meet high-purity standards suitable for feed and pharmaceutical applications. Quality is assured through rigorous in-process controls and final batch testing. A comprehensive Certificate of Analysis (COA) detailing purity, potency, and impurity profiles is provided with each shipment. Production can be aligned with relevant pharmacopeial guidelines (e.g., USP, EP) for specific grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and degradation.
