Dimethylethanolamine
Dimethylethanolamine (DMAE or DMEA) is an organic compound with the formula (CH3)2NCH2CH2OH. It is bifunctional, containing both a tertiary amine and primary alcohol functional groups. It is a colorless viscous liquid. It is used in skin care products for improving skin tone and also taken orally as a nootropic. It is prepared by the ethoxylation of dimethylamine. Industrial uses Dimethylaminoethanol is used as a curing agent for polyurethanes and epoxy resins. It is a precursor to other chemicals, such as the nitrogen mustard 2-dimethylaminoethyl chloride. The acrylate ester is used as a flocculating agent. Related compounds are used in gas purification, e.g. removal of hydrogen sulfide from sour gas streams. Nutraceutical uses The bitartrate salt of DMAE, i.e. 2-dimethylaminoethanol (+)-bitartrate, is sold as a dietary supplement. It is a white powder providing 37% DMAE. Animal tests show possible benefit for improving spatial memory and working memory.Edward D Levin, Jed ...

N-Methylethanolamine
''N''-Methylethanolamine is an alkanolamine with the formula CH3NHCH2CH2OH. It is flammable, corrosive, colorless, viscous liquid.Matthias Frauenkron, Johann-Peter Melder, Günther Ruider, Roland Rossbacher, Hartmut Höke "Ethanolamines and Propanolamines" in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2002, Wiley-VCH, Weinheim. It is an intermediate in the biosynthesis of choline. With both an amine and a hydroxyl functional groups, it is a useful intermediate in the chemical synthesis of various products including polymers and pharmaceuticals. It is also used as a solvent, for example in the processing of natural gas, where it is used together with its analogs ethanolamine and dimethylethanolamine. Production ''N''-Methylethanolamine is produced industrially by reacting ethylene oxide with excess methylamine in aqueous solution. This reaction yields a mixture of the 1:1 addition product NMEA (1) and - by a further addition of another ethylene oxide - the 1:2 ...
