Monoethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is an organic chemical compound with the formula HOCH2CH2NH2. The molecule is bifunctional, containing both a primary amine and a primary alcohol. Monoethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia. Its derivatives are widespread in nature; e.g., lipids. The monoethanolamine comprise a group of amino alcohols. A class of antihistamines is identified as ethanolamines, which includes carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, and doxylamine.

- Gas Treating: MEA is widely used in gas treating processes, particularly in the removal of acidic components such as hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas, refinery gas streams, and other industrial gases. It reacts with acidic gases to form stable salts or complexes, which can then be separated from the gas stream.
- Cosmetics and Personal Care Products: MEA is utilized in the formulation of various cosmetics and personal care products, including shampoos, hair conditioners, creams, lotions, and soaps. It acts as a pH adjuster, emulsifier, and surfactant, helping to stabilize formulations and enhance product performance.
- Textile Processing: MEA is employed in textile processing as a softener and pH adjuster. It helps to improve the feel and texture of fabrics, as well as to control the pH of dye baths and printing pastes during dyeing and printing processes.
- Corrosion Inhibition: MEA is used as a corrosion inhibitor in metalworking fluids, coolants, and boiler water treatment formulations to protect metal surfaces from corrosion. It forms a protective film on metal surfaces, preventing corrosive reactions with water and other chemicals.
