Science

Mechanism of Action

This ingredient operates principally as a surfactant, effectively reducing surface tension, and as an emulsifier, stabilizing oil and water phases within a formulation. As a polyethylene glycol (PEG) derivative, it additionally serves as a humectant, attracting and retaining moisture in the skin, a solubilizer for other compounds, and a conditioning agent. Furthermore, PEGs are known to enhance the dermal penetration of various active ingredients in topical applications.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated PEG diesters, including PEG-8 DODECENYLSUCCINATE, affirming their safety when formulated to be non-irritating. While generally approved by both CIR and the FDA (even for limited food use), its application is not advised on broken skin. The ingredient is permissible in EWG VERIFIED products, provided it adheres to specific use restrictions and warnings, largely due to potential contamination from toxic impurities such as ethylene oxide and 1,4-dioxane during manufacturing.
