벤질(C=12-14)알킬디메틸암모늄염화물

용도Benzalkonium chloride is a highly concentrated quaternary ammonium antimicrobial used in a broad number of applications. Benzalkonium chloride (BAK) is a common preservative used in ophthalmic medications and is the active ingredient in some skin disinfectants and hand sanitizers. BAK is known to be effective in killing bacteria and enveloped viruses. However, its activity against non-enveloped viruses is unknown. Benzalkonium chloride (as Roccal or Zephiran) was found to inactivate influenza, measles, canine distemper, rabies, fowl laryngotracheitis, vaccinia, Semliki Forest, feline pneumonitis, meningopneumonitis, and herpes simplex viruses after 10 min of exposure at 30 C or at room temperature. Poliovirus and encephalomyocarditis virus were not inactivated under the same conditions. Benzalkonium chloride is also used as a topical anti-infective in medicine as well as a germicide for cleansing food and dairy utensils, and as a controlling agent for swimming pool algae. It is also an additive in deodorants and hairdressing preparations.
