Chemical compound

Dimethylethanolamine (DMAE orDMEA) is anorganic compound with the formula(CH3)2NCH2CH2OH. It isbifunctional, containing both atertiary amine andprimary alcoholfunctional groups. It is a colorless viscous liquid. It is used in skin care products for improving skin tone and also taken orally as anootropic. It is prepared by theethoxylation ofdimethylamine.[2]

Industrial uses

[edit]

Dimethylaminoethanol is used as a curing agent for polyurethanes and epoxy resins. It is a precursor to other chemicals, such as thenitrogen mustard 2-dimethylaminoethyl chloride.[3] Theacrylate ester,dimethylaminoethyl acrylate is used as a flocculating agent.[4]

Related compounds are used in gas purification, e.g. removal ofhydrogen sulfide fromsour gas streams.

Human uses

[edit]

Thebitartrate salt of DMAE, i.e.N,N-dimethylethanolamine bitartrate, is sold as a dietary supplement.[5] It is a white powder providing 37% DMAE.[6]

Animal tests show possible benefit for improvingspatial memory[7] andworking memory.[8]
