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. [2] [3] Dimethylethylamine is a malodorous, volatile liquid at room temperature that is excreted at greater concentrations with larger dietary intake of trimethylamine. [1]

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.
