About

A short-chain PEG-ethoxylated ester of oleic acid that acts as a lipophilic surfactant, primarily used in applications requiring deep oil-phase integration.

PEG-3 Dioleate has one of the shortest ethoxylation chains in this series (3 EO), giving it predominantly lipophilic character. EU Regulation 1223/2009 does not list specific restrictions for this ingredient. The short EO chain increases concern for potential interaction with skin barrier compared to higher-EO homologues; SCCS advises quality testing for 1,4-dioxane and related impurities.

Skin benefits

  • Strong oil-phase integration and emollient effect
  • Effective for rich, occlusive skincare formulations

Known concerns

  • Higher lipophilicity may increase skin penetration potential
  • 1,4-dioxane residual concern typical of low-EO ethoxylates
