WebAbstract The biodegradation of dialkyldimethylammonium compounds in aqueous solutions indicates that part of the degradation pathway includes the Cope elimination reaction, which does not occur under mild conditions in the absence of microorganisms. Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound used as antiseptic/disinfectant. It causes the disruption of intermolecular interactions and the dissociation of lipid bilayers. The bacteriostatic (prevent growth) or bactericide (kill microorganism) activity of DDAC depends on its concentration and the growth phase of the microbial po…

WebThe most commonly used QAC disinfectants are the benzalkonium chlorides, also known as alkyl dimethyl benzyl ammonium chlorides. Abbreviations for benzalkonium chloride include BAC, BZK,BKC, and ADBAC. The concentration of benzalkonium chloride in disinfectants and cleaning supplies is usually between 0.01 and 1%, but can be as high as 5%. WebOther quaternary ammonium compounds, such as dialkyldimethylammonium compounds, are also commonly used as biocides and some manufacturers of hospital disinfectant products have substituted BAC with didecyldimethylammonium chloride (DDAC) [6].
