Benzalkonium Chloride (BKC) 50% is a concentrated, colorless to slightly yellow liquid solution of a quaternary ammonium compound, serving as a broad-spectrum antimicrobial, disinfectant, preservative, and cationic surfactant used across healthcare, cosmetics, water treatment, and industrial cleaning for its potent bactericidal, virucidal, fungicidal, and algaecidal properties. This solution effectively eliminates pathogens, prevents microbial growth in products like hand sanitizers, eye drops, and shampoos, and offers benefits like fabric softening and odor control in laundry.
