Although not entirely elucidated, the bactericidal action of benzalkonium chloride is believed to be due to the disruption of intermolecular interactions. Such disruption can cause the dissociation of cellular membrane lipid bilayers of bacteria, resulting in compromised cellular permeability control and the leakage of important cellular contents. Additionally, other important molecular complexes like enzymes which control the maintenance of a great range of respiratory and metabolic cellular activities, are also susceptible to such deactivation. Consequently, a variety of critical intermolecular interactions and tertiary structures in very highly specific biochemical systems that allow bacterial agents to function normally can be readily disrupted or deactivated by cationic surfactants like benzalkonium chloride. .
When used as an active ingredient in products like antibacterial, antiseptic, or disinfectant soaps, topical sanitizers, or cleaning agents, benzalkonium is primarily implemented in its salt form, benzalkonium chloride, where it may often be the only active ingredient present and indicated for the primary purpose of topical washing to decrease bacteria on skin . Conversely, when implemented as an excipient ingredient in a variety of multidose aqueous nose, eye, or ear products, benzalkonium chloride is being used as the antimicrobial preservative of choice to facilitate effective bactericidal and fungicidal actions to help minimize the growth of unwanted organisms in the multidose containers .
