Benzalkonium Chloride 50%
Benzalkonium Chloride 50% (CAS 121-54-0) is a quaternary ammonium compound widely used as a broad-spectrum biocide and disinfectant.
Description
Benzalkonium Chloride (BAC) 50%, with CAS number 121-54-0 and chemical formula C22H40ClN, is a prominent member of the quaternary ammonium compound (QAC) family. This cationic surfactant is synthesized by the alkylation of tertiary amines with alkyl halides, resulting in a mixture of homologous alkylbenzyldimethylammonium chlorides, typically with alkyl chain lengths ranging from C12 to C18, with C12 and C14 being the most prevalent. BAC acts as a potent biocide due to its ability to disrupt microbial cell membranes, leading to leakage of intracellular components and eventual cell death. It exhibits efficacy against a wide range of microorganisms, including gram-positive and gram-negative bacteria, fungi, and some viruses. Its mechanisms of action involve denaturation of proteins and enzymes, inhibition of cellular metabolism, and interference with cell permeability. The 50% concentration provides a versatile solution for dilution into various end-use formulations, offering a balance between efficacy and handling safety. Its stability over a broad pH range and good compatibility with many other excipients make it a preferred choice in numerous applications requiring antimicrobial control.
Applications
Benzalkonium Chloride 50% finds extensive application across various industries due to its broad-spectrum antimicrobial properties. In the healthcare sector, it is crucial for formulating skin antiseptics, wound disinfectants, and surface sanitizers for medical equipment and premises. The water treatment industry utilizes it for controlling microbial growth in cooling towers, swimming pools, and industrial water systems. In agriculture, it serves as a disinfectant for farm equipment, animal housing, and as a component in some crop protection formulations. The food and beverage industry employs BAC for sanitizing processing equipment, surfaces, and pipelines to prevent contamination. Furthermore, it is incorporated into household and institutional cleaning products, personal care items like hand sanitizers and cosmetics, and as a preservative in various industrial products.
