PPG-15 Stearyl Ether Benzoate

What is PPG-15 Stearyl Ether Benzoate?

PPG-15 Stearyl Ether Benzoate is a synthetic ester formed by reacting polypropylene glycol (15 units) stearyl ether—a chain of propylene oxide molecules linked to stearyl alcohol—with benzoic acid. This creates a versatile ingredient commonly used in skincare, haircare, and makeup products within the emollient and solvent categories. It functions by reducing surface tension for better spreadability, imparting a lightweight silky feel, and enabling the incorporation of fragrances and oils into water-based formulas. Its low viscosity helps stabilize emulsions, preventing separation, while providing lubrication that mimics natural skin oils without heaviness. Derived entirely from petrochemical sources, it supports formulation of non-greasy creams, lotions, and serums.
