About

A highly ethoxylated castor oil amide used as a nonionic surfactant and emulsifier; the high degree of ethoxylation makes it milder than lower ethoxylated ricinoleamides.

PEG-40 RICINOLEAMIDE is the polyethylene glycol (40 mol EO average) amide of ricinoleic acid, derived from castor oil. It functions as a nonionic surfactant and emulsifier in cosmetic formulations. It is not listed in EU Annex II or Annex III restriction lists. The high degree of ethoxylation (40 mol EO) significantly reduces the irritation and sensitization potential that is more associated with lower ethoxylated variants such as PEG-7 RICINOLEAMIDE. Trace 1,4-dioxane from ethoxylation is a standard impurity consideration.

Skin benefits

  • Mild nonionic emulsifier suitable for a range of cosmetic formulations
  • Provides emollient and skin-conditioning benefits

Known concerns

  • Potential trace 1,4-dioxane residue from ethoxylation process
