Diethanolamine, often abbreviated as DEA or DEOA, is an organic compound with the formula HN(CHâCHâOH)â. Pure diethanolamine is a white solid at room temperature, but its tendencies to absorb water and to supercool mean it is often encountered as a colorless, viscous liquid.
Triethanolamine, or TEA is a viscous organic compound that is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. It is a colourless compound although samples may appear yellow because of impurities.
Ethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is an organic chemical compound with the formula HOCH2CH2NH2 (C2H7NO). The molecule is bifunctional, containing both a primary amine and a primary alcohol. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia
