About
Methyleicosamidopropyl Ethyldimonium Ethosulfate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
This quaternary ammonium compound features a long alkyl chain (C20 eicosyl) attached to an amidopropyl quat structure. It functions as an antistatic and conditioning agent. The ethoxylate (ethosulfate) counterion reduces irritation compared to chloride-based quats. It is not individually listed in EU Annex II or III, and standard safety assessments for quaternary ammonium compounds apply. Typically used at low concentrations (0.1–2%) in rinse-off hair care products.
