Triethanolamine, or TEOA, is an organic compound with the chemical formula N(CH2CH2OH)3. It is a colourless, viscous liquid. It is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999.[3] It is a colourless compound although samples may appear yellow because of impurities.
