Description

Monoethanolamine

Monoethanolamine is an amine with alcohol and amine characteristics used in detergent, personal care, textile finishing, and wood treating products, as well as oil well and metalworking products for corrosion prevention​​. Also can be used as a cement grinding aid. Building block in the manufacture of triazine based corrosion inhibitors. A clear liquid with an ammonia-like odor. It is toxic, flammable, and corrosive. Uses: In sweetening natural gas and coal gas, as soaps or amides in heavy-duty detergents, in the production of ethylene amines, in aqueous solutions for scrubbing certain acidic gases, in feedstock in the production of detergents, emulsifiers, polishes, pharmaceuticals, corrosion inhibitors, and chemical intermediaries. CAS# (141-43-5).

MEA is a common ingredient in floor and tile cleaners and laundry detergents to help remove dirt, grease and stains. DEA is an ingredient in engine degreasers and industrial strength detergents. In gas treating processes for refineries and natural gas streams, MEA and DEA help remove contaminants from gasoline. DEA is also used as a chemical intermediate in agrochemicals to make pesticides, where it helps increase a pesticide’s ability to dissolve in water. TEA is used as a surfactant in agrochemicals to help pesticides disperse into crops.

MEA acts as a plasticizing agent, and chemical manufacturing plants may use MEA to remove carbon dioxide from ammonia gas in the production of synthetic ammonia.

The Cosmetic Ingredient Review has found that ethanolamine ingredients are safe as currently used in cosmetics and personal care products. FDA includes TEA, DEA and ethanolamine on its list of allowed indirect food additives.

To protect workers in industrial settings, OSHA has established a permissible exposure limit (PEL) for ethanolamine at 3 ppm in the air and requires employers to control workplace exposure below that PEL.

Monoethanolamine (MEA) : Used as acid gas absorbent, used in the pharmaceutical industry in the synthesis of fungicide, antidiarrheal agent; Fluorescent whitening agent in textile industry; Synthesis of high grade dyes in dyeing and chemical industry; Neutralizing agent in rubber industry and oil black industry; Also used in surfactant, rust inhibitor, cleaning agent, preservative, paint manufacturing, organic synthetic raw materials.

Ethanolamines

May also be known as: Monoethanolamine (MEA), Diethanolamine (DEA), Triethanolamine (TEA)
Ethanolamines are a family of chemicals that work as surfactants and emulsifying ingredients in personal care and cleaning products. They are made through a chemical reaction of ethylene oxide with ammonia. Common ethanolamines include monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA).

MonoEthanolamine (MEA) is a clear, colorless, viscous liquid with an odor of ammonia. The molecular formula is C2H7NO. Monoethanol amine combine 2 differents chemical functions, alcool and amine.

Monoethanolamine is produced by reacting ethylene oxide with aqueous ammonia.

This reaction produce monoethanolamine as well as diethanolamine and triethanolamine.

The ratio of each product can be controlled by the ratio of the reactants.

Uses
Monoethanolamine (MEA) is mainly used in detergents, personal-care products, textile, gas treating, wood treating, metal-working fluids, and catalysts for PU foams.

Ethanolamine, also called 2-aminoethanol or monoethanolamine (MEA), is a viscous, hygroscopic organic chemical compound that is both a primary amine (due to an amino group) and a primary alcohol (hydroxyl group). Used as a surfactant, fluorimetric reagent, and to remove CO₂ and H₂S from natural gas and other gases. Ethanolamine is widely distributed in biological tissue and is a component of lecithin. Ethanolamine is the second-most-abundant head group for phospholipids, substances found in biological membranes.

Monoethanolamine is an organic compound that is the simplest type of amine. It is a colorless liquid with a mild, neutral odor. Monoethanolamine has been shown to be an effective antimicrobial agent, inhibiting bacterial growth by reacting with water vapor and nitrogen atoms in the environment. Monoethanolamine has also been shown to inhibit the production of nitric oxide and other reactive nitrogen species, which may account for its antimicrobial properties. The inhibition of nitric oxide synthesis may also account for monoethanolamine’s ability to improve locomotor activity in mice. This chemical can be used as a reagent in analytical methods such as gas chromatography and solid phase microextraction.
