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. It is prepared by the ethoxylation of dimethylamine.^[2]

Industrial uses

It is a precursor to other chemicals, such as the nitrogen mustard 2-dimethylaminoethyl chloride.^[3] 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.

Neutraceutical uses

The bitartrate salt of DMAE, i.e. 2-dimethylaminoethanol (+)-bitartrate, is sold as a dietary supplement.^[4] It is a white powder providing 37% DMAE.^[5]
