Description and Uses

Cetylpyridinium is a quaternary ammonium 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%. Formulations containing cetylpyridinium have been used as antiseptic agents in the treatment of gingivitis and as antimicrobial agents in raw food processing.

Antibacterial in cough lozenges and syrups; emulsifier.
