hexadecylpyridinium

Cetylpyridinium (used in a form of chloride salt) is a cationic surface-active agent and has a broad antimicrobial spectrum, with rapid killing of gram-positive pathogens and yeast in particular. It is suggested that interaction with bacteria occurs by the disruption of membrane function, leakage of cytoplasmic material, and ultimately the collapse of the intra-cellular equilibrium. The drug is used under various trade names as an oral OTC hygiene product (mouthwash, dental kits, etc.) to control the dental plaque and to prevent the subsequent gingivitis. — NCATS
