Description

Benzalkonium Chloride is a versatile quaternary ammonium compound (quat) widely recognized for its potent antimicrobial and surfactant properties. This makes it an essential active ingredient for formulators requiring effective biocidal action and surface activity. Industries such as pharmaceuticals, personal care, disinfectant manufacturing, and water treatment rely on its efficacy and stability. Our supply of Benzalkonium Chloride CAS NO 85409-22-9 ensures consistent quality for critical applications.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, and hand sanitizers for its broad-spectrum efficacy against bacteria, fungi, and viruses.
• Pharmaceutical & Cosmetic Preservative: Used as a preservative in eye drops, nasal sprays, and various cosmetic products to prevent microbial contamination and extend shelf life.
• Algaecide & Biocide in Water Treatment: Employed in industrial cooling towers, swimming pools, and process water systems to control algae and slime-forming bacteria.
• Agricultural Applications: Acts as a fungicide and disinfectant for seed treatment and equipment sanitation in agricultural settings.
• Textile & Leather Processing: Serves as a softening agent, antistatic agent, and biocide in fabric and leather treatment processes.
• Household & Institutional Cleaning: Found in all-purpose cleaners, floor care products, and fabric softeners for its cleaning and antimicrobial benefits.

Quality Control

Our Benzalkonium Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for assay, impurity profiles, and microbiological efficacy. Certificates of Analysis (COA) are provided with every shipment, documenting compliance with relevant standards such as USP, EP, or FCC where applicable. We are committed to supply chain reliability and consistent product performance for our global B2B partners.

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. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
