Description

Benzalkonium Chloride is a versatile quaternary ammonium compound (quat) widely recognized for its potent antimicrobial and surfactant properties. Its primary value lies in its efficacy as a broad-spectrum biocide and cationic surfactant, offering reliable performance at low concentrations. This makes it a critical ingredient for manufacturers in the pharmaceutical, personal care, and industrial water treatment sectors seeking effective preservation and disinfection solutions. The compound is commercially available in various concentrations, typically as aqueous or alcoholic solutions, to suit diverse formulation needs.

Application

Benzalkonium Chloride (CAS NO 63449-41-2) serves as a key functional ingredient across multiple industries due to its dual role as a disinfectant and surfactant.

• Pharmaceuticals & Healthcare: Used as a preservative in nasal sprays, eye drops, and topical antiseptic solutions, and as a disinfectant for medical devices and hard surfaces.
• Personal Care & Cosmetics: Acts as a preservative and antimicrobial agent in products like hand sanitizers, wet wipes, shampoos, and conditioners.
• Water Treatment: Employed as an algicide and bactericide in industrial cooling towers, swimming pools, and wastewater systems.
• Household & Institutional Cleaning: A primary active ingredient in disinfectant sprays, wipes, and surface cleaners for its ability to kill germs on contact.
• Agriculture: Used as a disinfectant for equipment and facilities in animal husbandry and aquaculture.
• Industrial Processes: Functions as a phase transfer catalyst and a biocide in metalworking fluids, pulp, and paper production.
