1,1,1-Trimethylolpropane trioleate

1,1,1-Trimethylolpropane trioleate (CAS 57675-44-2, EC 260-895-0) is a synthetic ester produced by esterifying trimethylolpropane with oleic acid. It is commercially available under trade names including Hatcol 4323, Priolube 1427, Unister H 381, Edenor TMP 05, and Synative TMP 05. No E-code designation applies to this substance.

In lubricant formulations, this triester functions as a base fluid or additive, providing film-forming protection on metal surfaces under high-load conditions relevant to metalworking and automotive drivetrain applications. Its branched ester structure also makes it effective as a plasticizer in polymer processing, where it reduces intermolecular friction within the polymer matrix to improve flexibility.

This material is subject to REACH registration requirements for EU supply. It is available in standard industrial drum and IBC packaging formats. Procurement teams should confirm grade specifications directly with the supplier, as oleic acid purity influences the final ester profile.
