Monoethanolamine is recommended as a component of dishwashing detergents, detergents, multi-purpose detergents and disinfectants. Monoethanolamine can also be used as a neutralizing agent in car washes, dehumidifiers and wax removers and to prevent corrosion.
Monoethanolamine has been used as a neutralizing agent for anionic emulsifiers.
Ethanolamines are used to purify natural gas and petroleum gases to absorb carbon dioxide. Monoethanolamine in carbon dioxide gas systems can play an important role as a selective adsorbent in the production of ammonia, liquid carbon dioxide and dry ice, which in the latter case needs to be recovered.
