Overview

Dimethylaminoethanol, also known as dimethylethanolamine (DMAE and DMEA respectively), is a primary alcohol. This compound also goes by the names of N,N-dimethyl-2-aminoethanol, beta-dimethylaminoethyl alcohol, beta-hydroxyethyldimethylamine and Deanol. It is a transparent, pale-yellow liquid.

Biochemical significance

Dimethylaminoethanol is related to choline and may be a biochemical precursor to the neurotransmitter acetylcholine, although this conclusion has been disputed based on a 1977 rat experiment.^[2] It is commonly believed that dimethylaminoethanol is methylated to produce choline in the brain, but this has been shown not to be the case (in a rat experiment).^[2] It is known that dimethylaminoethanol is processed by the liver into choline; however, in a rat experiment the choline molecule is charged and cannot pass the blood–brain barrier.^[2] In the brain, DMAE is instead bound to phospholipids in place of choline to produce phosphatidyl-dimethylaminoethanol. This is then incorporated into nerve membranes, increasing fluidity and permeability, and acting as an antioxidant.^[3]

Uses

Industrial uses

Dimethylaminoethanol is used as a curing agent for polyurethanes and epoxy resins. It is also used in mass quantities for water treatment, and to some extent in the coatings industry. It is used in the synthesis of dyestuffs, textile auxiliaries, pharmaceuticals, emulsifiers, and corrosion inhibitors. It is also an additive to paint removers, boiler water and amino resins. It forms a number of salts with melting points below room temperature (ionic liquids) such as N,N-dimethylethanolammonium acetate and N,N-dimethylethanolammonium octanoate, which have been used as alternatives to conventional solvents.^[4]

2-Dimethylaminoethyl chloride hydrochloride is an intermediate made from dimethylaminoethanol that is widely used for the manufacture of pharmaceuticals.^[5]

Biomedical research

Short-term studies have shown an increase in vigilance and alertness with a positive influence on mood following administration of DMAE, vitamins, and minerals in individuals suffering from borderline emotional disturbance.^[6] Research for ADHD has been promising, though inconclusive.^[7] A study showed dimethylaminoethanol to decrease the average life span of aged quail.^[8] Three other studies showed an increase in lifespan of mice ^[9]

The bitartrate salt of DMAE, i.e. 2-dimethylaminoethanol (+)-bitartrate, is sold as a dietary supplement.^[10] It is a white powder providing 37% DMAE.^[11]
