Science
Mechanism of Action
This copolymer primarily functions by engaging in hydrogen bonding with water molecules within the stratum corneum, thereby reducing transepidermal water loss and preserving skin hydration. It also contributes to forming a thin, protective film on the skin's surface to mitigate dehydration. Beyond its hydrating properties, its PEG structure allows it to function as a penetration enhancer, potentially facilitating the absorption of other active compounds in a formulation.

Stability
The ingredient is recognized for improving the texture and enhancing the stability of cosmetic products. It exhibits broad compatibility with a diverse range of solvents and chemicals, including aqueous solutions, alcohols, and oils. However, higher molecular weight PEG compounds within the copolymer may demonstrate reduced compatibility with organic solvents.
Safety
Safety Profile
While polyethylene glycols (PEGs) are generally considered to have good skin tolerance by the CIR Expert Panel, the safety of this specific copolymer is currently under review, with insufficient data available for a conclusive assessment. A related compound, PEG/PPG-17/6 copolymer, has been identified as warranting further investigation. A specific case of allergic contact dermatitis attributed to methoxy PEG-17/dodecyl glycol copolymer (Elfacos OW 100) has been reported, indicating a potential for individual sensitivity. Its function as a penetration enhancer also implies that careful consideration of other formulation ingredients is necessary to manage their absorption profiles.
