Science
Mechanism of Action
This ingredient operates by significantly lowering the surface tension between immiscible components, thereby enabling the formation and stabilization of emulsions. As a polyethylene glycol (PEG) derivative, it exhibits humectant qualities, attracting and retaining water molecules within the stratum corneum through hydrogen bonding. This action enhances skin hydration, mitigates trans-epidermal water loss (TEWL), and supports the skin's natural barrier function, leading to a refatting and skin-smoothing effect.

Stability
While a specific optimal pH range for PEG-15 Glyceryl Oleate stability was not identified, related PEGylated emulsifiers, such as PEG-100 Stearate, are generally recognized for their stability across a wide pH spectrum.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Glyceryl Oleate (the non-PEGylated form) safe for cosmetic use. Although PEG-15 Glyceryl Oleate itself has not been specifically assessed for safety by an industry panel for cosmetic applications, it is designated as safe for general or limited use in food by the FDA. EWG rates this ingredient with low concern for cancer, allergies & immunotoxicity, and developmental & reproductive toxicity. However, it is important to note that PEGs, in general, carry a potential risk of contamination with impurities like ethylene oxide and 1,4-dioxane from the manufacturing process.
