  • Applications

    Ethyl isopentyl succinate, CAS 28024-16-0, is primarily used in fragrance and cosmetic formulations as a fruity aroma ingredient and fragrance fixative in perfumery and personal care products; it also serves as a lightweight solvent or carrier in these systems. It is used as a plasticizer and processing aid for polymers and coatings to improve flexibility and handling of plastics and finishes. In industrial manufacturing, it is often employed as an intermediate in the synthesis of other succinate esters and related compounds. It can be incorporated into household and cleaning products to provide fragrance and act as a solvent in specialty formulations. Additionally, it may be used in polymer and adhesive formulations as a compatible ester that influences performance and aroma. Its use is subject to local regulations and formulation limits.
