Triethanolamine, often abbreviated as TEA, is a viscous organic compound that is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Triethanolamine is a strong base.[3] Triethanolamine can also be abbreviated as TEOA, which can help to distinguish it from triethylamine. Approximately 150,000 tonnes were produced in 1999.[4] It is a colourless compound although samples may appear yellow because of impurities.
