EPA is taking steps to address emissions of ethylene oxide from some types of industrial facilities across the country.
Ethylene oxide is a flammable, colorless gas used to make other chemicals that are used in making a range of products, including antifreeze, textiles, plastics, detergents and adhesives. Ethylene oxide also is used to sterilize equipment and plastic devices that cannot be sterilized by steam, such as medical equipment. EPA is committed to reducing risks from ethylene oxide.
