C20-40 Alkyl Stearate

C20-40 Alkyl Stearate is a synthetic ester formed from the esterification of stearic acid with long-chain fatty alcohols in the C20-C40 range, resulting in a high-melting waxy solid. Its unusually long carbon chain length gives it exceptional structuring capabilities and a distinctive dry, powdery skin feel that distinguishes it from shorter-chain esters. Formulators prize it for its ability to build viscosity and add body to anhydrous systems, sticks, and emulsions while simultaneously imparting a non-greasy, velvety after-feel on the skin.
