  • Applications

    Cetyl Stearate (CAS 1190-63-2) is a wax ester widely used in cosmetics and personal care as an emollient and conditioning agent, providing slip and a smooth feel in creams, lotions, and makeup bases; it also functions as a waxy thickener and texture enhancer in emulsions and can act as a lubricant in hair care formulations to improve combability. In addition, it serves as a structuring component in lipstick and lip care products, contributing to stability and controlled melt behavior. It is occasionally used as a wax additive to adjust rheology in coatings and plastics, delivering slip and gloss without relying on volatile solvents.
