PEG-16 OLEATE
Safety score · 0–100
Good
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
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
