N-alkyl ethylbenzyl dimethyl ammonium (C12-C14)

Quaternary ammonium compounds like n-alkyl C12-C14 dimethyl ethylbenzyl ammonium chloride irreversibly bind to the phospholipids and proteins of microbial cell membranes, thereby impairing membrane permeability. Consequently, the antibacterial actions of n-alkyl C12-C14 dimethyl ethylbenzyl ammonium chloride generally stem from the capacity of bacterial cells to absorb the compound, causing the disruption or dissociation of cellular membrane lipid bilayers of bacteria, resulting in compromised cellular permeability control and the leakage of important cellular contents. In particular, the antimicrobial activity of quaternary ammonium with an alkyl chain is related to lipolhilia and peaks between C12 and C16 for both gram-positive and gram-negative bacterial strains. Specifically, in gram-positive bacteria, the agent becomes bound to the wall proteins and is, therefore, able to enter and destroy the membrane. Additionally, in some microbes, n-alkyl C12-C14 dimethyl ethylbenzyl ammonium chloride can cause a leak in metabolites with low molecular weights, resulting in metabolic injury and modification of permeability for the microbe.

It is for these aforementioned mechanisms of action that n-alkyl C12-C14 dimethyl ethylbenzyl ammonium chloride is capable of eliciting antimicrobial activity when used as a disinfectant. However, when used as an agent for routine cleaning where surface contamination with pathogenic bacteria and viruses does not necessarily present a hazard, the use of n-alkyl C12-C14 dimethyl ethylbenzyl ammonium chloride and its antimicrobial actions may not be entirely necessary or recommended, considering quaternary ammonium compounds like n-alkyl C12-C14 dimethyl ethylbenzyl ammonium chloride can persist on cleaned surfaces and contribute to prolonged topical exposure to individuals.
