Benzalkonium chloride

Description

Benzalkonium chloride is a type of cationic surfactant widely used for its antimicrobial properties. It is effective against bacteria, fungi, and some viruses, making it a common ingredient in disinfectants, antiseptics, and preservative solutions. Chemically, it belongs to the quaternary ammonium compounds (quats) class and typically appears as a clear, yellowish solution or solid. Its applications span healthcare, household cleaning, personal care products, and industrial processes, where it functions to reduce microbial contamination. Benzalkonium chloride is generally stable, water-soluble, and relatively low in toxicity when used as directed, though prolonged exposure may cause skin or eye irritation.
