  • Applications

    Dibenzyl succinate (CAS 103-43-5) is predominantly used as a plasticizer for polymers and resins, improving flexibility and processability. It is commonly employed as a fragrance ingredient and fixative in perfumery, helping to extend scent retention in cosmetic and household formulations. It may act as a solvent or carrier in various industrial formulations and can serve as an intermediate in organic synthesis. In coatings and inks, it can function as a plasticizer/flow modifier, aiding film formation and flexibility. In cosmetics and personal care, it is used as a fragrance component in formulations. Its use is subject to local regulations and formulation limits.
