Ethanolamines

Ethanolamines are multifunctional compounds that combine amine and alcohol properties, giving them broad utility in industrial manufacturing, chemical processing, and consumer products. In gas treatment applications, Ethanolamines are widely used to remove acidic gases such as carbon dioxide (CO₂) and hydrogen sulfide (H₂S) from natural gas and refinery streams, ensuring cleaner fuels and more efficient energy production. They are also key components in surfactants and detergents for personal care products, household cleaners, and textile treatments, where they improve solubility, emulsification, and performance.

In addition to cleaning and energy applications, Ethanolamines play an important role in metalworking, construction, pharmaceuticals, and agriculture. They are used as corrosion inhibitors, cement grinding aids, and additives in coatings and adhesives, helping extend equipment life and improve material properties. In specialty chemical synthesis, Ethanolamines serve as intermediates for active pharmaceutical ingredients (APIs), herbicides, and pesticides, while also providing compatibility in cosmetics, lubricants, and oilfield formulations. With their versatility, reactivity, and wide industrial demand, Ethanolamines remain essential building blocks for modern chemical production and everyday applications.
