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.

  • Improves wet combing in hair care
  • Provides soft feel to skin and hair

Known concerns

  • Potential skin sensitizer (quaternary ammonium sensitization documented)
  • Restricted to rinse-off use at low concentrations in EU
  • Eye irritant at higher concentrations
