Cetearyl Stearate
What is Cetearyl Stearate?
Cetearyl Stearate is a wax ester produced by combining cetearyl alcohol—a mixture of cetyl and stearyl alcohols obtained from coconut or palm kernel oils—with stearic acid, a long-chain fatty acid from vegetable sources. It falls into the emollient and co-emulsifying agent category in skincare formulations, particularly oil-in-water emulsions like moisturizers, lotions, and creams. In products, it stabilizes mixtures of water and oils, preventing separation while delivering a lightweight, spreadable consistency. At skin temperature, it softens to create a breathable film, aiding in moisture retention and improving the overall sensory experience without greasiness. This functionality supports its roles in conditioning and protecting the skin barrier.
