Science

Mechanism of Action

This ingredient reduces surface tension, enabling the stable mixing of oil and water phases, thereby creating robust emulsions. It enhances the volume and stability of foam, while simultaneously improving product viscosity and consistency. As a polyethylene glycol derivative, it can facilitate the deeper penetration of other active compounds into the skin.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG-2 Cocamide is safe for cosmetic use when formulated to be non-irritating, a finding affirmed in a 2015 assessment. While related PEG Cocamine ingredients have shown potential for mild to moderate skin and ocular irritation, these effects were not observed on intact skin when formulations were appropriately adjusted. Manufacturers must implement purification steps to control for potential 1,4-dioxane contamination and should exercise caution by adjusting formulations for use on damaged or compromised skin.
