  • Applications

    Dicetyl adipate (CAS 26720-21-8) is commonly used as a plasticizer and emollient. In cosmetics and personal care, it provides slip and a smooth, conditioning feel as an emollient and texture enhancer in creams, lotions, and color cosmetics. In polymers and plastics, it acts as a non-volatile plasticizer to improve flexibility and processing of flexible vinyl, polyurethane, and related resin systems. In coatings and inks, it serves as a processing aid and plasticizer to enhance film formation and film flexibility. In adhesives and sealants, it functions as a plasticizer/additive to adjust rheology and final film properties. Its use is formulation- and regulation-dependent, and it is selected where a lipophilic plasticizer/emollient is advantageous.
