  • Applications

    Diisodecyl adipate (CAS 27178-16-1) is primarily used as a plasticizer for flexible polymers such as PVC, improving softness, flexibility and low-temperature performance. It also functions as a processing aid and plasticizer in coatings, inks, sealants, and adhesives. In cosmetics and personal care, it serves as an emollient and solvent for actives and fragrance components. In addition, it is employed in some household products and cleaning formulations as a compatible solvent or plasticizer additive, with use governed by local regulations and formulation limits.
