Mechanism of Action
This ingredient functions primarily as a skin conditioning emollient, actively softening and smoothing the skin's surface. As an emulsifier, it plays a critical role in stabilizing immiscible oil and water components, creating homogenous emulsions. Additionally, it serves as a solubilizer and solvent, facilitating the integration of oily or sparingly water-soluble ingredients into aqueous formulations.

Stability
OLIVE OIL PEG/PPG-3/1 ESTERS are water-soluble and exhibit non-greasy characteristics, typical of polyethylene and polypropylene glycols. They are non-ionic compounds effective in forming stable oil and water emulsions and solubilizing various ingredients into aqueous systems. No specific optimal pH range for stability has been identified.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG Propylene Glycol Derivatives, which include similar olive oil propylene glycol esters, are safe for cosmetic use when formulated to be non-irritating. The safety assessment for related ingredients was re-evaluated in 2022 due to updated usage data and significantly increased concentrations, with the highest reported use concentration for a related PEG/PPG ester being 28% in lipstick.
