  • Applications

    Stearyl Palmitate (CAS 2598-99-4) is a high molecular weight fatty ester commonly used as an emollient and texture modifier in cosmetics and personal care, providing slip and a conditioning skin feel in creams, lotions, balms, and lip products. In polymer and plastics processing, it acts as a waxy lubricant/processing aid to improve flow and reduce friction during molding and extrusion. As a wax additive, it can modify rheology, gloss and water resistance in coatings and inks. It may also function as a conditioning wax or carrier in household formulations and other consumer products.
