Current Intelligence Bulletin 22: Ethylene Thiourea (ETU) - CDC
Ethylene thiourea has been shown to be carcinogenic and teratogenic (causing malformations in offspring) in laboratory animals. In addition, ethylene thiourea can cause myxedema (the drying and thickening of skin, together with a slowing down of physical and mental activity), goiter, and other effects related to decreased output of thyroid hormone.

Ethylene-thiourea is a white crystalline solid used as an accelerator in the curing of neoprene and other elastomers. Approximately 3,500 workers may be potentially exposed in the rubber industry. In addition, exposure to ethylene-thiourea results from the widely used ethylene bisdithiocarbamate fungicides.
