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 constituent of benzalkonium chloride. Benzalkonium chloride is a mixture of benzyl alkyl dimethyl ammonium compounds, in which the alkyl chains are mainly n-C12H25 (dodecyl), n-C14H29 (tetradecyl), and n-C16H33 (hexadecyl). Cetaxonium chloride is characterized by high lipophilicity and low solubility in water. It can be used as an anti-infective agent, a surfactant, and a pharmaceutical excipient. As an ammonium salt preservative, it is applied in studies related to oral, throat, and eye infections, and it is primarily used in pharmaceutical raw materials for its anti-inflammatory function.
