Tri-n-octylamine

Tri-n-octylamine (CAS 1116-76-3) is a tertiary aliphatic amine with the molecular formula C24H51N, commercially available under trade names including Alamine 336, Farmin 08, and Farmin T 08, and commonly abbreviated as TNOA or TOA. It carries no assigned E-code and is classified under HS code 29211980.

In solvent extraction processes, TNOA acts as a liquid ion exchanger, selectively binding metal ions or organic acids through protonation of its nitrogen atom. In polymer and coating formulations, it functions as an antistatic agent and catalyst for curing reactions, while in personal care applications it serves as an emulsifier and hair conditioning agent by adsorbing onto charged surfaces.

TNOA is supplied in technical and high-purity grades to meet requirements under REACH registration. Standard packaging includes drums and IBC containers. Procurement teams should confirm grade specification against intended application, particularly where food-contact or cosmetic compliance documentation is required.
