There are many advantages to understanding an ethylene oxide[1] (EO or EtO) sterilization process when considering the different sterilization options. A knowledge of the process may prevent unnecessary product testing or may identify product changes which may be required prior to attempting to sterilize with EO. The following information, although generic in nature, is designed to provide basic information on the ethylene oxide sterilization process.

The EO sterilization process has been employed by the health care industry to sterilize medical devices[2] since the early 1940s (Griffith and Hall – 1940, 1943)1. Although not as well controlled as the processes of today, the anatomy of the process itself remains remarkably similar to the earlier process designs. One can attribute these similarities to the nature of the gas itself.

In its pure form (100 percent), ethylene oxide vapor is flammable and explosive...
