Monoethanolamine (MEA) application opportunities, primarily in detergents, personal care products, textile finishing and wood treating. Other applications include use as “down hole” in oil well chemicals and in metalworking to prevent corrosion, and as catalysts that promote stability during the reaction process in the manufacture of flexible and rigid urethane foams.
Because MEA combines the properties of amines and alcohols,. As an amine, MEA is mildly alkaline and react with acids to form salts or soaps. As an alcohol, MEA is hygroscopic and can be esterfied. Monoethanolamine is available as MEA, MEA LFG and MEA ICF:
-
MEA is a commercial grade of monoethanolamine (CAS number: 141-43-5).
-
MEA Low Freezing Grade (LFG) is a variation of MEA commercial grade for easier
handling in colder ambient temperatures (freezing point: -13oC/8.6oF). It is an 85%
solution of MEA with 15% water.
-
MEA Iron & Chloride-free Grade (ICF) is iron and chloride free and contains <= 1
ppm chloride, <= 0.5% pm iron.
Detergents
-
MEA imparts a reserve alkalinity to the laundry bath, which is essential to efficient cleaning.
-
MEA is an effective oil and anti-redeposition agent.
Personal Care
• Fatty acids neutralized with MEA are used as emulsifiers for oil-in water emulsions such as gel-type industrial hand cleaners, aerosol shave creams, and hand and body lotions.
Textile Finishing
-
MEA is used as reaction intermediates for the preparation of durable press fabric finishes and softeners.
-
When reacted to form amine soaps, useful as scouring agents for wool and silk because of its low alkalinity.
-
Because it is hygroscopic, MEA is used in the preparation of vat printing pastes. Wood Treating
