Description

Benzalkonium Chloride is a versatile and highly effective quaternary ammonium compound (quat) widely recognized for its potent antimicrobial properties. Its primary value lies in its ability to provide broad-spectrum biocidal activity against bacteria, fungi, and viruses, making it a cornerstone ingredient in numerous industrial and consumer formulations. This product is essential for manufacturers in the pharmaceutical, personal care, water treatment, and industrial disinfection sectors seeking a reliable and well-characterized active ingredient. The compound is commercially available in various concentrations, typically as aqueous or alcoholic solutions, to suit diverse application needs.

Application

• Pharmaceutical & Medical Disinfectants: A key active ingredient in antiseptic solutions, surgical scrubs, wound cleansers, and disinfectant wipes for surfaces and non-critical medical devices.
• Personal Care & Cosmetics: Used as a preservative and antimicrobial agent in products like hand sanitizers, wet wipes, shampoos, conditioners, and eye care solutions.
• Industrial & Institutional (I&I) Cleaning: Formulated into hard surface disinfectants, algaecides, and sanitizers for food processing plants, dairies, breweries, and commercial facilities.
• Water Treatment: Employed as a biocide to control microbial growth in industrial cooling water systems, swimming pools, and wastewater treatment.
• Agricultural Applications: Used as a disinfectant in animal husbandry for barns, equipment, and as a topical antiseptic for livestock.
• Textile & Leather Processing: Serves as a sanitizing and preservative agent in the production and finishing of fabrics and leather goods.

Quality Control

Our Benzalkonium Chloride is manufactured under strict quality management systems. Production adheres to relevant pharmacopeial standards (such as USP/EP for pharmaceutical grades) and Good Manufacturing Practices (GMP). Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting purity, composition, and physical properties are available upon request to ensure full traceability and compliance for your specific application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and strong acids. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
