Ethylene oxide (commonly abbreviated as EtO or C₂H₄O) is a colorless, flammable gas with a faintly sweet odor, belonging to the epoxide family of chemical compounds. It is widely used in industrial processes due to its reactivity and versatility. Structurally, ethylene oxide consists of a three-membered ring composed of two carbon atoms and one oxygen atom, making it a cyclic ether.

The primary industrial applications of ethylene oxide include its use as a precursor in the production of ethylene glycol, a key component in antifreeze and polyester fibers. It is also utilized in the synthesis of other chemicals such as ethanolamines, surfactants, and solvents. Additionally, ethylene oxide is employed as a sterilizing agent in the medical field, where its ability to penetrate packaging materials and kill bacteria, viruses, and spores makes it valuable for sterilizing surgical instruments, medical devices, and pharmaceutical products.

Ethylene oxide is highly reactive and can undergo ring-opening polymerization to form polyether polymers. This property is exploited in the manufacturing of various plastics and resins. However, its reactivity also poses significant safety concerns. Ethylene oxide is classified as a carcinogen by regulatory agencies such as the International Agency for Research on Cancer (IARC) and the U.S. Environmental Protection Agency (EPA), due to its potential to cause cancer with prolonged exposure. Occupational exposure to ethylene oxide has been linked to increased risks of leukemia and other cancers.

Due to its hazardous nature, strict regulations govern its handling, storage, and disposal. Workplace exposure limits are enforced to minimize risks, and alternative sterilization methods are increasingly being explored to reduce reliance on ethylene oxide. Proper ventilation, protective equipment, and training are essential for those working with this chemical to ensure safety.
