Science
Mechanism of Action
This ingredient primarily functions as a lipophilic emulsifier, critically enabling the stable blending of otherwise immiscible oil and water components within a cosmetic formula. As a surfactant, it effectively lowers surface tension, enhancing product spreadability and cleansing efficacy. Additionally, as a polyethylene glycol derivative, PEG-2 Oleate can act as a penetration enhancer, facilitating the deeper delivery of other active ingredients into the skin, with its effectiveness influenced by molecular weight, the overall formulation, and the skin's barrier integrity.

Stability
This ingredient maintains stability within a pH range of 5 to 8. Related compounds indicate potential instability under hot alkaline conditions, which can lead to hydrolysis and compromise formula integrity.
Conflicts
- Hot alkaline conditions (potential for hydrolysis)
- Damaged or compromised skin (increased risk of sensitization or systemic toxicity with PEG compounds)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEGs and related PEG fatty acid esters, including PEG-2 Oleate, are safe for use in cosmetics. While typically used between 0.1% and 10%, it is crucial to avoid application on damaged or severely compromised skin due to documented instances of sensitization and nephrotoxicity in burn patients, although studies on intact skin have shown no such adverse effects.
