EtO Molecule

According to the US Environmental Protection Agency, Ethelene Oxide is a human carcinogen: “Ethylene oxide (EtO) is a colorless gas used to make other chemicals that are used in making a range of products, including antifreeze, textiles, plastics, detergents and adhesives. EtO also is used to sterilize equipment and plastic devices that cannot be sterilized by steam, such as medical equipment.”


The EPA determined that long term exposure to EtO may lead to harmful health effects: “EtO is a human carcinogen. It causes cancer in humans,” including:

  • Breast cancer
  • Non-Hodgkin’s lymphoma
  • Myeloma
  • Lymphocytic leukemia
  • Other blood and lymph cancers
  • Cancers of the prostate, pancreas, kidneys, lung, brain, stomach, ovaries, and bladder

Other health effects associated with exposure to Ethylene Oxide may include:

  • Miscarriage and reproductive harm
  • Headaches
  • Nausea
  • Memory loss
  • Impaired hand-eye coordination
  • Cognitive and neurological impairment
  • Eye irritation and damage
  • Nerve damage

According to the EPA: “Scientific evidence in humans indicates that regular exposure to EtO over many years increases the risk of cancers of the white blood cells, including non-Hodgkin lymphoma, myeloma, and lymphocytic leukemia. Studies also show that long-term exposure to EtO increases the risk of breast cancer in women.”
