Description
N-Ethyldiethanolamine (CAS 139-87-7), also known as diethanolethylamine or ethyldiethanolamine, is a tertiary alkanolamine with the molecular formula C6H15NO2. It carries no assigned E-code and is classified under HS code 29221930 within the broader amines category.
In metalworking fluids, N-ethyldiethanolamine functions as a pH buffer and corrosion inhibitor by neutralising acidic by-products and forming protective complexes on metal surfaces. In water treatment formulations, it acts as a chelating agent, sequestering hardness ions to prevent scale deposition. It also supports emulsification in textile and paper processing auxiliaries.
N-Ethyldiethanolamine is supplied as a technical-grade liquid and is subject to REACH registration requirements within the European Economic Area. Procurement professionals should confirm SDS compliance and purity specifications with the supplier prior to order. Standard packaging formats include drums and IBC containers.
