Description

Butyl oleate (CAS 142-77-8) is a fatty acid ester produced by reacting oleic acid with n-butanol. It carries no E-code designation and is sold under trade names including Kessco 554, Witcizer 100, Witcizer 101, Advaplast 42, and Hallco C 503.

In metalworking and textile processing, butyl oleate functions as a lubricant and plasticizer, reducing friction between metal surfaces and softening fiber finishes by penetrating substrate structures. In coatings and sealant formulations, it acts as a plasticizing solvent that improves film flexibility and aids dispersion of pigments and fillers.

Butyl oleate is supplied as a technical-grade liquid and falls under REACH registration requirements for EU market supply. It is classified under HS code 2916150000 for customs purposes. Packaging formats typically include drums and intermediate bulk containers, with documentation available to support procurement and formulation compliance workflows.
