About
Di-c12-18 Alkyl Dimonium Chloride is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
Di-C12-18 Alkyl Dimonium Chloride is a twin-chain quaternary ammonium compound used as a conditioning agent and antistatic in rinse-off hair and skin products. Under EU Regulation 1223/2009 and related SCCS assessments, dialkyl quaternary ammonium compounds require attention to residual monomer content and sensitization potential. They are generally restricted to rinse-off products at low concentrations and are not permitted in leave-on products at high levels due to potential for skin and eye irritation.
