Cetylpyridinium (chloride)

Cetylpyridinium is a quaternary ammonium-containing cationic surfactant with broad-spectrum antiseptic activities. It is active against S. mutans, S. sanguis, E. coli, Oxford Staphylococcus, and C. albicans in media (MICs = 1.25-62.5 µg/ml) and against Oxford Staphylococcus in pooled human saliva (MICs = 7.8-15.6 µg/ml). Cetylpyridinium slows plaque formation for at least 21 days compared to a deionized water control in a rat incisor plaque model when applied topically at concentrations ranging from 0.025 to 2%.Formal Name: 1-hexadecyl-pyridinium, monochloride.
