Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

PEG-3 dioleate is a PEG fatty-acid ester used as a mild emulsifier and emollient. It is well established in cosmetics but, as with all PEGs, depends on tight manufacturing purity controls.

Skin benefits

  • PEG fatty-acid ester used as an emulsifier and emollient
  • Improves spreadability and skin feel in lotions and creams
  • Compatible with a wide range of cosmetic systems
  • Helps solubilise lipophilic actives

Known concerns

  • PEG ingredients carry residual ethylene oxide / 1,4-dioxane purity concerns
  • Manufacturing-quality dependent for purity
  • Less preferred in 'PEG-free' natural positioning
