About

LAURYLPYRIDINIUM CHLORIDE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Laurylpyridinium chloride is a quaternary ammonium compound (QAC) where a lauryl chain is attached to a pyridinium ring. It functions as a surfactant and antimicrobial agent, making it useful in oral care and preservative systems. However, QACs can be skin irritants at higher concentrations and may disrupt the skin microbiome. EU restrictions on QACs in cosmetic products apply, and sensitization potential exists. Careful formulation is required.
