Science
Mechanism of Action
This ingredient functions as a surface-active agent, reducing the surface tension between immiscible substances like oil and water, thereby enabling their stable incorporation within a formulation. On the skin, it facilitates the removal of impurities, contributes to foam generation in cleansing products, and imparts a conditioning sensation.

Stability
Polyethylene glycols and their derivatives, including this ingredient, are favored for their broad viscosity and solubility profiles. However, prolonged exposure to temperatures exceeding 50°C may induce oxidation, potentially leading to peroxide formation. Finished products are advised to include antioxidants to prevent these radical mechanisms.
Conflicts
- The risk of skin irritation may increase when formulated alongside other ingredients known to be problematic.
- Requires strict adherence to maximum impurity concentrations for residual ethylene oxide (max 1 mg/kg), 1,4-dioxane (max 10 mg/kg), polycyclic aromatic compounds, and heavy metals (max 10 mg/kg).
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEGylated alkyl glycerides, including PEG-60 Glyceryl Diisostearate, are safe for cosmetic use under current practices and concentrations, provided they are formulated to be non-irritating. Generally, PEGs and their derivatives demonstrate good skin tolerance, minimal ocular or dermal irritation, and a negligible sensitizing potential on healthy skin.
