PPG-15 Stearyl Ether
What is PPG-15 Stearyl Ether?
PPG-15 Stearyl Ether is a synthetic polyether compound formed by linking stearyl alcohol—a long-chain fatty alcohol from stearic acid—with approximately 15 propylene oxide units. This creates a flexible, hydrophobic molecule with excellent lubricating qualities. Primarily used in the emollient class of cosmetic ingredients, it appears in moisturizers, lotions, serums, and hair conditioners. In formulations, it works by depositing a thin, non-greasy layer on the skin that mimics sebum, reducing friction between skin cells and improving overall texture. It also boosts product flow, aiding even application, and solubilizes fragrances or oils in water-based systems while contributing to emulsion stability. Its light molecular weight ensures quick absorption without stickiness.
