Stearyl Caprylate
What is Stearyl Caprylate?
Stearyl Caprylate is a fatty acid ester produced by combining stearyl alcohol, a C18 fatty alcohol often derived from vegetable sources like palm or coconut, with caprylic acid, a medium-chain fatty acid from coconut or palm kernel oil. It falls into the emollient and skin conditioning category in cosmetics, appearing in moisturizers, lotions, creams, and foundations. Functionally, it works by depositing a thin lipid layer on the skin's surface, which fills microscopic gaps to create a smoother texture and enhances product slip for easier application. As a skin conditioner, it promotes suppleness by aligning with the skin's natural sebum structure. Its lightweight, non-oily profile makes it suitable for various formulations, contributing to a velvety after-feel and aiding in emulsion stability without heaviness.
