Products Description of Benzyldimethylhexadecylammonium Chloride CAS#122-18-9
Benzyldimethylhexadecylammonium chloride (also known as Cetaxonium chloride or hexadecyldimethylbenzylammonium chloride) is a lipophilic cationic quaternary ammonium surfactant. It represents a defined single-chain component of commercial benzalkonium chloride mixtures (which typically combine n-C12H25, n-C14H29, and n-C16H33 alkyl homologues).
Characterized by its hydrophobic nature and modest aqueous solubility, it serves as an efficient anti-infective agent, formulation surfactant, and pharmaceutical excipient. Due to its quaternary ammonium preservative and anti-inflammatory characteristics, it is heavily referenced in research focusing on mucosal, throat, and ophthalmic infection treatments.
