  • Applications

    Stearyl arachidate (CAS 22432-79-7) is a high-melting-point wax ester primarily used as an emollient and thickener in cosmetics and personal care; it acts as a slip agent and lubricant in coatings and industrial inks; it is added to plastics and polymers to improve slip and processability; it serves as a waxy constituent in household and industrial wax formulations for polishing and surface care; and it can function as a rheology-modifying additive in adhesives to adjust film formation and set characteristics.
