About

Cetrimonium Tosylate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Cetrimonium tosylate is a cationic quaternary ammonium compound (QAC) functioning as an antistatic agent and surfactant in cosmetic formulations. In the EU, QACs are under regulatory scrutiny due to concerns about aquatic toxicity (H411) and potential preservative co-formulant effects. The SCCS has flagged cetrimonium chloride for eye irritation potential, and similar concerns extend to tosylate variants.
