Science
Mechanism of Action
This ingredient works on the skin by effectively binding moisture, which significantly improves hydration levels and prevents formulations from drying out prematurely. As a nonionic surfactant, it aids in dissolving other cosmetic substances and boosting the penetration efficiency of active ingredients, thereby refining the overall texture and feel of the product, while also providing softening and lubricating benefits.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has found 'Alkyl PEG Ethers,' including PEG-8 ALLYL ETHER, safe for use in cosmetics when formulated to be non-irritating, with concentrations up to 85% being reviewed. However, a significant concern is the potential for contamination with manufacturing impurities such as ethylene oxide and 1,4-dioxane, which are linked to health concerns and irritation. Due to these potential impurities, it is advised against use on sensitive skin. There is no specific SCCS opinion on PEG-8 ALLYL ETHER, and its FDA listing as an indirect food additive does not directly address its cosmetic safety profile.
