The concentration of Ethylene Oxide Treatment is an important key factor affecting its sterilization quality. The common concentration range is: 450-1200mg/L; as the temperature rises, the bactericidal effect of ethylene oxide is strengthened, and the sterilization temperature is generally 35°C-60°C; the water content of the sterilized items, the dry environment of the microorganism itself and the relative humidity of the sterilized environment all have a significant impact on the sterilization effect of ethylene oxide, and the common relative humidity is 100% 45-75; Sterilization time is generally 105-300min. These factors directly affect the success or failure of sterilization. Only when the four key factors are balanced can the quality of sterilization be guaranteed.

The packaging, loading, sterilization treatment of sterilized items, and the protection outside the bacteria also affect the sterilization effect. The surface properties and thickness of packaging materials have an impact on the sterilization effect, and materials that are easy for ethylene oxide to penetrate and have little residue should be selected.

Although ethylene oxide has strong penetrability to objects and can penetrate micropores to reach the deep part of objects, but due to the different densities of different substances, the penetration of ethylene oxide gas to them is also different, so in When choosing packaging materials for sterilized or sterilized items, it is necessary to consider factors such as packaging beauty, lightness, sealing, and economy, and more importantly, whether it can be penetrated by ethylene oxide gas, so that the contents of the packaging The material meets the requirements of sterilization.
