Description

Benzalkonium Chloride is a versatile and highly effective quaternary ammonium compound (quat) widely used as a cationic surfactant and antimicrobial agent. Its primary value lies in its potent biocidal activity against a broad spectrum of bacteria, fungi, and viruses, coupled with its excellent surface-active properties. This makes it an indispensable ingredient for manufacturers in the pharmaceutical, personal care, and industrial disinfection sectors who require reliable and efficient sanitization and preservation.

Application

• Pharmaceutical & Medical Disinfectants: A key active ingredient in antiseptic solutions, surgical scrubs, wound cleansers, and disinfectant wipes for hospitals and clinics.
• Personal Care & Cosmetics Preservation: Used as a preservative in eye drops, nasal sprays, and various cosmetic formulations to prevent microbial contamination.
• Industrial & Institutional (I&I) Cleaning: Formulated into hard surface disinfectants, algaecides for swimming pools, and sanitizers for the food processing industry.
• Agricultural Applications: Employed as a fungicide and disinfectant for seed treatment and equipment sanitation.
• Textile & Leather Processing: Acts as a softener, antistatic agent, and biocide in fabric finishing and leather treatment.
• Oilfield & Water Treatment: Serves as a biocide to control microbial growth in industrial water systems, cooling towers, and oil recovery processes.

Quality Control

Our Benzalkonium Chloride is manufactured under strict quality management systems. We offer grades compliant with various pharmacopoeial standards, including USP and EP, where applicable. All production batches undergo rigorous analytical testing to ensure consistent purity, composition, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, alkyl chain distribution, and impurity profiles is provided with each shipment.

Storage

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