Triethanolamine (TEA) Monoethanolamine (MEA) Diethanolamine (DEA)

What is Triethanolamine (TEA)

TEA Triethanolamine %85 is a colourless compound although samples may appear yellow because of impurities. TEA Triethanolamine B85 LFG 85% is a low-freeze grade version of Triethanolamine B85, a mix of triethanolamine and diethanolamine. The product is an aqueous blend designed to provide a lower freeze point product for those who can tolerate the presence of water in their applications.

Freezing will occur at approximately -9°C versus the 18°C expected for Triethanolamine 85.

What is Monoethanolamine (MEA) 

Ethanolamine, also known as 2-aminoethanol or monoethanolamine, is a colorless, viscous liquid with a faint odor. It is an organic compound that contains both amine and alcohol functional groups. Ethanolamine is commonly used as a feedstock in the production of detergents, emulsifiers, and pharmaceuticals.

In addition, ethanolamine can also be used as a corrosion inhibitor, as a gas-scrubbing agent to remove carbon dioxide and hydrogen sulfide from natural gas and refinery streams, and as a solvent for a variety of substances, including resins, dyes, and waxes.

Ethanolamine is also used in the production of certain herbicides, such as glyphosate, and in the synthesis of some amino acids, such as alanine and glycine. However, ethanolamine can be harmful if ingested or inhaled, and it can cause skin and eye irritation. Therefore, proper precautions should be taken when handling this substance.

What is Diethanolamine (DEA)

Diethanolamine DEA is primarily used as a gas-scrubbing agent to remove carbon dioxide and hydrogen sulfide from natural gas and refinery streams. It is also used as a surfactant, emulsifier, and corrosion inhibitor in personal care products, detergents, metalworking fluids, and other industrial applications.

In addition, Diethanolamine is used in the production of various chemicals, including plasticizers, resins, and pharmaceuticals. It is also used as a solvent in the manufacture of dyestuffs and pigments, as well as in the synthesis of rubber and pharmaceutical intermediates.

However, exposure to high concentrations of DEA Diethanolamine can cause skin and eye irritation, as well as respiratory problems, and it can be harmful if ingested. Therefore, appropriate precautions should be taken when handling this substance. The use of DEA in personal care products has been controversial due to concerns over potential health risks, and its use has been restricted in some countries.
