Technical Document

Brief Overview
Triethanolamine, also known as TEA, appears as a colorless viscous liquid. It is strongly alkaline and is mainly used as a pH regulator. It helps to form emulsions by reducing the surface tension of the substance to be emulsified. It is hygroscopic in nature and soluble in water and alcohols. It gives a slight ammoniacal odor due to the presence of an amine.

Manufacturing Processes
TEA is produced by the reaction of ethylene oxide with aqueous ammonia. Mono and diethanolamine are produced together and the product can be obtained by altering the stoichiometry of the reactants.
