Product Name: Benzalkonium Chloride (BAC)
CAS Number: 8001-54-5 / 63449-41-2
Other Names: BAC, Alkyldimethylbenzyl ammonium chloride
Product Description
Benzalkonium chloride (BAC) is a cationic surfactant widely used as a bactericide, preservative, and disinfectant. It exhibits high efficacy and broad-spectrum antibacterial activity against Gram-positive and Gram-negative bacteria, fungi, algae, and enveloped viruses.
BAC is widely used in the pharmaceutical, personal care, food, water treatment, and petrochemical industries, both on its own and as a synergistic bactericidal ingredient in formulations.
Benzalkonium chloride combines surface activity with bactericidal properties, providing both cleaning and long-lasting antimicrobial protection. It is therefore widely used in products such as disinfectants, hand sanitizers, wipes, conditioners, and anti-corrosion coatings.
