Neopentyl glycol dioleate

Neopentyl glycol dioleate (CAS 42222-50-4, EC 255-713-1) is a diester synthesised from neopentyl glycol and oleic acid. It is commercially available under trade names including Hatcol 4322 and Priolube 1446, and is also referenced in literature as NSC 65468. No E-code applies to this substance.

In lubricant formulations, neopentyl glycol dioleate functions as a base fluid or additive in metalworking fluids and automotive gear oils, where its ester structure provides film-forming lubricity that reduces metal-to-metal contact under load. It also acts as a plasticiser in polymer systems, improving flexibility by reducing intermolecular friction between polymer chains.

The material is subject to REACH registration requirements for EU supply and is handled under standard chemical compliance frameworks. It is typically supplied in drum or IBC formats depending on order volume. Prospective buyers should confirm grade specification and purity documentation directly with the supplier.
