Ethylene oxide Mixture with CO2
CARBON DIOXIDE AND ETHYLENE OXIDE MIXTURE, WITH MORE THAN 9% BUT NOT MORE THAN 87% ETHYLENE OXIDE
A carbon dioxide and ethylene oxide mixture is a combination of two gases: carbon dioxide (CO2) and ethylene oxide (C2H4O).
It is a colorless gas with an ether-like odor. Carbon dioxide is noncombustible.
Ethylene oxide is flammable. The mixture can asphyxiate by displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used as a fumigant.
The mixture can asphyxiate by displacement of air, meaning it can reduce the amount of oxygen available if it leaks into an environment.
It’s important to note that under prolonged exposure to fire or intense heat, containers holding this gas mixture may rupture violently and rocket.
This mixture is used as a fumigant, which means it’s employed to disinfect or purify an area by filling it with fumigant gas.
However, due to the properties of ethylene oxide, such as being highly flammable and a health hazard, it’s crucial to handle this mixture with extreme care and follow all safety guidelines.
Ethylene oxide is also known to be a carcinogen, so safety measures are paramount when dealing with this substance.

DSW offers an ethylene oxide-carbon dioxide mixture in various purity and concentrations.
Ethylene Oxide “Gas” Sterilization. ETO is a colorless gas that is flammable and explosive. The four essential parameters (operational ranges) are gas concentration (450 to 1200 mg/l, temperature (37 to 63°C, relative humidity (40 to 80%)(water molecules carry ETO to reactive sites), and exposure time (1 to 6 hours). It is most commonly mixed with CO2 as sterilization gas and used to sterilize instruments with long lumens, such as endoscopes and all materials that must be fixed but cannot withstand higher temperatures.
