About

A nonionic surfactant based on oleic acid (plant-derived) used in hair and skin formulations; safe overall with minor concerns about ethoxylation byproducts.

Polyethylene glycol oleamide (4 EO) is a nonionic surfactant providing conditioning and emollient properties alongside its surfactant function. The moderate EO chain length provides a balance between water solubility and mildness. No EU restrictions apply; residual 1,4-dioxane from manufacturing is controlled to acceptable levels by industry standards.

Skin benefits

  • provides skin smoothing and conditioning
  • improves product texture and stability

Known concerns

  • trace 1,4-dioxane impurity from ethoxylation process
