General description
Mono ethylene glycol (also known as MEG, EG, 1,2-ethanediol or, 1,2 Dihydroxyethane) is an organic compound with the formula C2H6O2. It is a slightly syrupy viscous liquid with a clear, colorless appearance, and a sweet taste (but it is toxic in high concentrations) that emits virtually no odor and absorbs water easily. It’s miscible with water, alcohols, and many other organic compounds. The primary hazard is its threat to the environment; since it is a liquid that can easily penetrate the soil and contaminate groundwater and nearby streams. To prevent this, immediate steps should be taken to limit its spread.
