BARQUAT® 50-65A
Quaternary Ammonium Compounds
EPA Registered
Barquat® 50-65A is a blend of alkyl dimethyl benzyl ammonium chlorides. When used as an active ingredient in FIFRA1 registered formulations such as hard surface disinfectants, sanitizers and/or certain types of water treatment formulations, these products have been found to provide superior biocidal action against a broad spectrum of microbial organisms such as: bacteria, fungi, viruses, and algae. This “first generation” quaternary ammonium compound delivers potent germicidal action in most applications.
