Ethylene Glycol

Ethylene glycol, C2H6O2, is commonly used as an antifreeze agent in automobile cooling systems. It is also used in deicing solutions for aircraft and boats. In pure form it is a colorless clear liquid with a sweet taste and a slightly syrupy texture. If ingested, ethylene glycol can damage the kidneys, heart and nervous system.

Other uses include solvents for the paint and plastic industry, photographic developing solutions, hydraulic brake fluids and ink for stamp pads and ballpoint pens.

Propylene Glycol

Propylene glycol, C3H8O2, is used as an antifreeze agent in automobile cooling systems, though not so commonly as ethylene glycol. It is used in deicing solutions. Propylene glycol is a clear colorless liquid that is essentially odorless and tasteless. It is relatively safe for use in food, in contrast to ethylene glycol. It is used as a moisture absorber to maintain maintain moisture in certain medicines, cosmetics and food products. It is used as a solvent for food colors.

Propylene glycol is used in making polyester compounds and as a solvent in the paint and plastics industries. It is used to create artificial smoke or fog for theatrical uses.

Other names for this compound are methyl glycol and methylethylene glycol.
