  • Applications

    Butyl Stearate is a fatty ester primarily used as an emollient and skin-conditioning ingredient in cosmetics and personal care. It is also used as a solvent and fragrance carrier in perfumery and fragrance formulations, aiding the dissolution and dispersion of fragrance components. In the plastics and coatings sector, it acts as a plasticizer and lubricant to improve flexibility and processability of polymers and coatings formulations. It may be used as a processing aid and lubricity additive in industrial manufacturing, as well as a component in coatings and inks to enhance flow and flexibility. In household and cleaning formulations, it can serve as an oil-based carrier component to balance texture and ease of dispersion.
