Towelette Disinfectant Wipe Benzalkonium Chloride (BZK) 5.5" x 8" 100/Box BOX

Benzalkonium chloride (alkyl dimethyl benzyl ammonium chloride), or BZK, is a mixture of alkylbenzyl dimethylammonium chlorides of various alkyl chain lengths. It is commonly used as an antiseptic and spermicide. This product is a nitrogenous cationic surface-acting agent belonging to the quaternary ammonium group. The greatest bactericidal activity is associated with the C12-C14 alkyl derivatives. BZK is readily soluble in water, alcohol, and acetone. Formulation requires great care as BZK can be inactivated by certain organic compounds, including soap, and must not be mixed with anionic surfactants. Hard water salts can also reduce biocidal activity. Although newer formulations are more resistant to deactivation, as with any disinfectant, it is recommended that surfaces are rinsed well before disinfection. Aqueous solutions of BZK are neutral to slightly alkaline, colorless, and nonstaining. Solutions foam profusely when shaken, have a bitter taste, and a faint almond-like odor, which is only detectable in concentrated solutions. The mechanism of bactericidal/microbicidal action is thought to be due to disruption of intermolecular interactions. This can cause dissociation of cellular membrane bilayers, which compromises cellular permeability controls and induces leakage of cellular contents.  BZK solutions are rapidly acting anti-infective agents with a moderately long duration of action. They are active against bacteria and some viruses, fungi, and protozoa. Bacterial spores are considered to be resistant. Solutions are bacteriostatic or bactericidal according to their concentration. Gram-positive bacteria are generally more susceptible than gram-negative. Activity is not greatly affected by pH, but increases substantially at higher temperatures and prolonged exposure times.
