Didecyl adipate

Didecyl adipate (CAS 105-97-5) is a diester plasticizer derived from adipic acid and decanol, commercially available under trade names including DB 31, Polycizer 632, and Dicapryl adipate. It carries no assigned E-code and is classified within the broader category of adipate ester plasticizers.

In PVC and polymer compounding, didecyl adipate improves low-temperature flexibility by disrupting polymer chain interactions, reducing brittleness in films and profiles. In lubricant formulations, its ester structure provides film-forming properties and thermal stability, making it suitable as a base fluid or additive in metalworking and automotive applications.

Didecyl adipate is supplied as a liquid-phase product and falls under REACH registration obligations for EU market supply. Procurement teams should confirm grade specifications, including purity and acid value, with the supplier prior to ordering.
