A polyethylene glycol ester of oleic acid that works as a nonionic surfactant and emollient, helping to blend oil and water phases in cosmetic formulations.

PEG-12 Dioleate is an ethoxylated fatty acid ester derived from oleic acid with an average of 12 ethylene oxide units. It is classified in the EU Cosmetics Regulation (EC 1223/2009) as a permitted surfactant and emollient with no specific concentration limits; however, residual 1,4-dioxane from the ethoxylation process must be monitored per SCCS guidance.

Skin benefits

  • Effective emollient that softens and smooths skin
  • Good emulsifying properties for stable formulations

Known concerns

  • Potential 1,4-dioxane impurity from ethoxylation process
  • May enhance skin penetration of other ingredients at low EO chain lengths
