Science
Mechanism of Action
This ingredient functions by forming a fine lubricating film on the skin's surface, which visually and tactilely improves smoothness and softness. As a solvent and carrier, it significantly enhances the uniform distribution of complex formulations like creams and balms. Additionally, related ether compounds demonstrate efficacy in dissolving crystalline UV filters and improving the wettability and capillarity of pigments, suggesting similar solvent capabilities for PPG-23 Oleyl Ether.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed PPG-23 Oleyl Ether within a group of 131 alkyl PEG/PPG ethers, concluding their safety in current cosmetic practices and concentrations when formulated to be non-irritating. Typical use concentrations for related compounds range from 2% to 10%, not exceeding the 25% maximum. Trace amounts of 1,4-dioxane, a potential carcinogen formed during ethoxylation, may be present but are generally considered acceptable below 30 ppm. Residual propylene oxide, a starting material, has been reported at maximum levels of 10 ppm in PPGs used for finished products.
