What are the effects of long-term exposure to ethylene oxide? asks Cassandra Dunn, Registered Nurse and Certified Federal Medical Investigator.

Ethylene oxide (C?H?O) is a chemical that is used to create other chemicals, like polysorbate 20 and polyethylene glycol (PEG), which are often more effective and less toxic.

Ethylene oxide is a very hazardous substance. At room temperature it is a flammable, carcinogenic, mutagenic, irritating, and anesthetic gas.
