| Benzethonium chloride is a new type of quaternary ammonium antimicrobial agent, which has a wide range of applications in the daily-use chemicals and cosmetics industries. In addition, as a bactericidal antimicrobial agent it has important applications in the field of medicine and health, for example, as the bacteriostatic component of eye drops or as the bacteriostatic ingredient of injections has been widely used in western countries. Benzethonium chloride is an essential key intermediate in the production of heparin sodium products. | |||||||||
