Used as an absorbent for carbon dioxide and hydrogen sulfide in natural gas and refinery operations due to its ability to react with acidic gases. Commonly employed in the formulation of surfactants, emulsifiers, and detergents because of its amphoteric nature, allowing it to function in both acidic and alkaline environments. Also used in the textile industry to improve fabric properties such as softness and antistatic resistance.

Plays a key role in the production of agrochemicals, pharmaceuticals, and cosmetics, particularly in the synthesis of ethanolamine salts and esters. Serves as a starting material for synthesizing other chemicals, including drugs, preservatives, and coatings.

Frequently used in personal care products such as shampoos, conditioners, and skin care formulations to adjust pH, enhance foaming properties, and provide moisturizing benefits. Also utilized in metalworking fluids as a corrosion inhibitor and emulsifying agent.
