Science
Mechanism of Action
This ingredient works by reducing the surface tension between oil and water phases, thereby creating stable emulsions essential for many cosmetic formulations. As an emollient, it helps to lubricate and soften the skin's surface. Its lower molecular weight structure is also indicated to potentially enhance the penetration of other active ingredients into the skin.

Stability
PEG esters, including oleates, are susceptible to hydrolysis under hot alkaline conditions, suggesting better stability in acidic to neutral pH environments.
Conflicts
- Hot alkaline conditions (potential hydrolysis)
- Damaged or compromised skin (potential penetration enhancement and hypersensitivity risks)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEGs and their derivatives are generally safe for use in cosmetics under intended conditions. However, application to damaged or compromised skin should be avoided due to potential hypersensitivity risks and observed nephrotoxicity in burn patients treated with PEG-based preparations. Manufacturers are urged to minimize impurities such as ethylene oxide and 1,4-dioxane. A specific maximum concentration for PEG-2 Oleate SE is not stated, but a related compound, PEG-55 propylene glycol oleate, was found safe at concentrations up to 10%.
