About

A polyethoxylated glyceryl ether of ricinoleic acid (15 EO units), functioning as a solubilizer and emollient in cosmetic formulations with mild surfactant properties.

PEG-15 Glyceryl Ricinoleate is derived from castor oil via glyceryl ester ethoxylation. The higher PEG chain length (15 vs 7-8) increases water solubility. As with all PEG-ethers, potential trace 1,4-dioxane contamination is a consideration. EU allows this ingredient with standard impurity thresholds; not restricted under Annex III.

Skin benefits

  • Emollient and skin softening
  • Solubilizing hydrophobic ingredients
  • Mild surfactant action
  • Improved product spreadability

Known concerns

  • 1,4-dioxane trace contamination from ethoxylation
  • PEG sensitivity concerns for compromised skin
  • Some ricinoleate derivatives may be restricted in specific product types
