Dibutylethanolamine

Dibutylethanolamine (DBAE, CAS 102-81-8) is a tertiary aliphatic amine with the molecular formula C10H23NO, also referenced as Dibutylaminoethanol or NSC 6330. It carries no E-code designation. The compound belongs to the ethanolamine-derived amine family and is supplied under EC number 203-057-1.

In metalworking fluids, DBAE functions as a pH buffer and corrosion inhibitor, neutralizing acidic byproducts and forming a protective layer on metal surfaces. In water treatment formulations, it acts as a dispersant, keeping scale-forming particles suspended and preventing deposition. Textile and leather processing operations use it as an emulsifier to stabilize aqueous chemical baths.

DBAE is available in industrial-grade liquid form and is subject to REACH registration requirements within the European Economic Area. Standard packaging includes IBC containers and drums. Procurement teams should confirm SDS compliance and regional transport classifications prior to ordering.
