A polyethylene glycol ester of oleic acid used as an emulsifier and surfactant in cosmetic formulations; it can cause mild skin or eye irritation in some users.

PEG-3 OLEATE is the polyethylene glycol (3 mol EO average) monoester of oleic acid, functioning as a nonionic surfactant and emulsifier in cosmetics. It is not subject to EU cosmetics restrictions (not listed in Annex II banned or Annex III restricted substances); however, as a lower-degree PEG ester it carries a mildly elevated irritation profile compared to higher ethoxylated variants. Trace 1,4-dioxane residues from ethoxylation manufacturing may be present.

Skin benefits

  • Effective emulsifier for oil-in-water formulations
  • Provides surfactant and cleansing properties

Known concerns

  • May cause mild skin or eye irritation at higher concentrations
  • Potential trace 1,4-dioxane residue from ethoxylation process
