Triethanolamine

Triethanolamine (TEA) is a viscous, colorless to pale yellow liquid with a mild, characteristic ammonia-like odor and low volatility. It is a tertiary alkanolamine—specifically, a tri-substituted ethanolamine—and is miscible with water and many organic solvents. TEA serves primarily as a chemical intermediate in the synthesis of surfactants, corrosion inhibitors, and emulsifiers, and is widely used to adjust pH and stabilize formulations. Its principal applications are in personal care products (e.g., shampoos, creams), industrial cleaners, metalworking fluids, and cement additives. It is also employed in gas treatment for acid gas removal and as a catalyst or curing agent in coatings and polyurethane foams.


At room temperature, it appears as colorless transparent viscous liquid with hygroscopicity and ammonia smell. It is alkaline, being irritating. It has a melting point of 21.2 °C, the boiling point of 360 °C, a flash point of 193 ° C, the relative density (d420) 1.1242 and refractive index (nD20) of 1.4852. It is miscible with water, ethanol and acetone, slightly soluble in ether, benzene and carbon tetrachloride.
