About

A higher ethoxylated oleic acid ester used as a mild nonionic emulsifier in cosmetics; well tolerated on skin with minimal irritation concerns.

PEG-16 OLEATE is the polyethylene glycol (16 mol EO average) monoester of oleic acid, serving as a nonionic surfactant and emulsifier in cosmetic formulations. It is not subject to EU cosmetics restrictions (not in Annex II or III). The high ethoxylation degree provides good water solubility and a low irritation profile, making it suitable for leave-on products. As with all PEG-derived ingredients, trace 1,4-dioxane from manufacturing may be present below concern thresholds.

Skin benefits

  • Excellent emulsifying agent for various cosmetic formulations
  • Provides emollient and skin-conditioning effects

Known concerns

  • Potential trace 1,4-dioxane residue from ethoxylation process
