General description

Ethanolamine is a colourless organic compound. It is a strong base and is miscible in water, alcohol, carbon tetrachloride and chloroform. It is highly toxic in nature and is a strong irritant. It is derived from ethylene oxide reacting with ammonia forming mono-, di-, and triethanolamine. It is widely used in manufacturing detergents when reacting with fatty acid. It is most commonly used a corrosion inhibitor.

Application

Ethanolamine may be used as an analytical standard for the determination of the analyte in cosmetic products, water samples and ethanolamine mixtures by various chromatography techniques.

Alkanolamines such as monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) are used as wetting agents in shampoos, lotions, creams, and other cosmetics. DEA is widely used to provide lather in shampoos and maintain a favorable consistency in lotions and creams.

Monolayer cultures of rat hepatocytes have been examined for their ability to secrete ethanolamine plasmalogen as a component of nascent lipoproteins. In culture medium from these cells, ethanolamine plasmalogen comprises approx. 20-30% of total ethanolamine glycerophospholipids when measured either as
