Science
Mechanism of Action
This ingredient deeply moisturizes the skin by delivering exogenous lipids that closely resemble the skin's natural sebum, thereby reinforcing the skin barrier and significantly reducing transepidermal water loss. Its hydrating properties help to counteract potential drying effects from other ingredients, promoting a smoother skin texture and reducing inflammation. Furthermore, as a polyethylene glycol (PEG) derivative, it efficiently blends oil and water, serving as an emulsifier to stabilize formulations, a surfactant to cleanse, and a solubilizer to integrate difficult-to-dissolve actives, fragrances, and colorants into clear solutions.

Safety
Safety Profile
The CIR Expert Panel deems this ingredient safe for cosmetic use, provided formulations are designed to be non-irritating. A critical consideration is its potential to enhance the penetration of other ingredients, necessitating careful formulation with actives whose safety profiles depend on minimal skin absorption. It should not be applied to compromised or damaged skin. Manufacturers are also advised to ensure the removal of common PEG impurities like ethylene oxide and 1,4-dioxane to maintain product integrity and safety.
