About

Stearamidopropyl Ethyldimonium Ethosulfate is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This quaternary ammonium salt is classified H302 (harmful if swallowed) and H318 (causes serious eye damage) under CLP regulation. It is used as an antistatic and conditioning agent in rinse-off and some leave-in hair care products. The compound lacks a CosIng Annex listing but is used in hair care formulations. Eye contact risk is the primary safety concern; proper formulation in non-eye-contact products limits consumer exposure. Systemic toxicity at used concentrations is considered low.

Skin benefits

  • Antistatic conditioning agent
  • Improves hair combability and smoothness
  • Provides cationic surface deposition for frizz control

Known concerns

  • H318 - causes serious eye damage
  • H302 - harmful if swallowed
  • Quaternary ammonium compounds may cause skin sensitization in susceptible individuals
