  • Applications

    Lauryl Stearate (CAS 5303-25-3) is a fatty ester primarily used as an emollient and slip agent in cosmetics and personal care, improving skin and hair feel, moisturizing properties, and spreadability. In fragrance and perfumery, it is commonly used as a fragrance carrier or solvent for fragrance oils. In the plastics and polymer sector, Lauryl Stearate often acts as a lubricant or processing aid to enhance handling and smoothness of the polymer. In coatings and inks, it can serve as a lubricant and slip additive to improve surface finish and processability. In pharmaceutical topical formulations, it may function as an excipient or vehicle for active ingredients in topical dosage forms.
