Chemical compound
Dimethylethanolamine (DMAE orDMEA ) is anorganic compound with the formula(CH3 )2 NCH2 CH2 OH . It isbifunctional , containing both atertiary amine andprimary 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 anootropic . It is prepared by theethoxylation ofdimethylamine .[ 2]
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.
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]
