Difference Between Ethylene and Propylene Glycol

May 01 2012Ethylene glycol and propylene glycol are organic compounds with alcohol functional groups The term "glycol" is used when there are two hydroxyl groups present in neighboring carbon atoms Their molecular formulas are different thus they have some different physical properties

Overview of Ethylene Glycol Toxicity

All animals are susceptible to ethylene glycol (EG) toxicity but it is most common in dogs and cats Most intoxications are associated with ingestion of antifreeze which is typically 95% EG These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems
