N,N-Dimethylethylamine (DMEA), sometimes referred to as dimethylethylamine, is an organic compound with formula (CH3)2NC2H5. It is an industrial chemical that is mainly used in foundries as a catalyst for epoxy resins and polyurethane as well as sand core production. Dimethylethylamine is a malodorous, volatile liquid at room temperature that is excreted at greater concentrations with larger dietary intake of trimethylamine.
The aim was to study the effect of trimethylamine (TMA) on the metabolism of the industrial catalyst N,N-dimethylethylamine to ascertain whether biological monitoring of industrial exposure to N,N-dimethylethylamine is compromised and excretion of the malodorous N,N-dimethylethylamine in sweat and urine is increased by dietary intake of TMA....Although the increased urinary and hidrotic excretion of N,N-dimethylethylamine may contribute to body odor problems, they were primarily due to TMA excretion, which is much the greater.
