About

Steardimonium Ethyl Cetyl Phosphate is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This phosphoric acid ester quaternary ammonium compound functions as an antistatic and conditioning agent in cosmetics. Quaternary ammonium phosphates of this type are generally well tolerated on skin with low irritation potential. The stearyl and cetyl chain lengths provide good substantivity to skin and hair. No specific EU Annex restrictions apply to this class of conditioning agents, and the ingredient is compliant with Regulation 1223/2009 as used in rinse-off and leave-on cosmetic formulations.

Skin benefits

  • Conditions and softens skin and hair
  • Improves combability and reduces static in hair
  • Functions as a mild emulsifier
