  • Applications

    Isoamyl Laurate (CAS 6309-51-9) is commonly used as an emollient and solvent in cosmetics and personal care products, providing slip and a pleasant skin feel while serving as a carrier for active ingredients. It can function as a fragrance carrier or solvent in perfumery, and may serve as a processing aid in cosmetic formulations. In polymer, plastics, and coatings formulations, it may act as a plasticizer or lubricity additive to improve processability and the smoothness of surfaces. It can also serve as a processing aid and solvent in industrial manufacturing formulations, including cleaning product bases, and can be used to dissolve and disperse other formulation components. Applications depend on local regulations and formulation limits.
