Application
Benzalkonium chloride (BKC, BAC) is a broad-spectrum quaternary ammonium compound widely used as an antimicrobial preservative, disinfectant, antiseptic, and cationic surfactant. In pharmaceutical formulations, it serves as a preservative in multi-dose ophthalmic solutions, nasal sprays, ear drops, and nebulizer solutions, ensuring sterility and extending shelf life. In personal care products, BKC acts as an antimicrobial agent in hand sanitizers, wet wipes, shampoos, soaps, deodorants, and cosmetics. For industrial applications, it is a highly effective disinfectant and sanitizer for hard surfaces, food processing equipment, swimming pools, and water treatment systems. In the healthcare sector, BKC-based formulations are used for surgical scrubs, instrument disinfection, and wound antiseptics. Its membrane-disruptive mechanism provides rapid bactericidal, fungicidal, and virucidal activity against gram-positive and gram-negative bacteria, enveloped viruses, and fungi.
