Products Description of Benzyldimethylhexadecylammonium Chloride CAS#122-18-9
Cetaxonium chloride, also known as hexadecyl dimethyl benzyl ammonium chloride, is a cationic quaternary ammonium surfactant and a component of benzalkonium chloride. Benzalkonium chloride itself is a mixture of benzyl alkyl dimethyl ammonium compounds, where the predominant alkyl chains are n-C12H25 (dodecyl), n-C14H29 (tetradecyl), and n-C16H33 (hexadecyl). Cetaxonium chloride is characterized by high lipophilicity and low solubility in water. It serves as an anti-infective agent, a surfactant, and a pharmaceutical excipient. As an ammonium salt preservative, it is utilized in research concerning oral, throat, and eye infections and is primarily employed in pharmaceutical raw materials for its anti-inflammatory function.
