The effects of three agents: alkyl-dimethyl-benzyl-ammonium chloride, benzalkonium chloride and didecyl-dimethyl-ammonium chloride, on the infectivity titre of CCoV in A72 cell lines, were studied at different concentrations. Quaternary ammonium chloride (QAC) compounds are the most common active ingredient found in disinfectants used in healthcare environments and have been used safely and effectively for many years. It said the long-lasting disinfectant, which is made of a chemical compound called quaternary ammonium chloride, would reduce the chances of viruses and … View Set. Quaternary ammonium compounds are prepared by the alkylation of tertiary amines with a halocarbon. Jennings, Megan C.; Buttaro, Bettina A.; Minbiole, Kevin P. C.; Wuest, William M. Quaternary ammonium compds. dynamics of microbial communities where QACs are a main line of defense against exposure to pathogens need to be better understood in terms of sublethal doses and antibiotic resistance. virus culture, isolation or neutralization assays) at a containment laboratory with inward directional airflow BSL-3).
