About
Oleamidopropyl 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.
Oleamidopropyl ethyldimonium ethosulfate is a quaternary ammonium cation (QAC) functionalized with an oleic fatty acid amide moiety, making it substantive to skin and hair through both ionic and hydrophobic interactions. It functions as an antistatic agent and hair conditioning agent. Quaternary ammonium compounds are widely used in rinse-off and leave-on cosmetics; this specific compound is not individually listed in EU Annex III or IV of Regulation (EC) No 1223/2009 but is covered by general safety provisions. The ethosulfate anion (ethyl sulfate) is of low toxicological concern.
Skin benefits
- Antistatic agent — reduces frizz and improves hair manageability
- Skin conditioning — imparts soft feel to skin and hair
Known concerns
- May cause mild eye irritation (quaternary ammonium class)
- Generally safe in rinse-off and leave-on products at normal use concentrations
