Ethylene oxide (ETO) sterilization is a widely used method for sterilizing medical equipment, pharmaceutical products, and other heat- or moisture-sensitive materials. ETO sterilization is effective in killing various microorganisms, including bacteria, viruses, and fungi. The effectiveness of ETO sterilization depends on several factors, including the concentration of ETO, the duration of exposure, the temperature, and the humidity. The optimal conditions for ETO sterilization vary depending on the type of material being sterilized, and the sterilization cycle must be carefully designed to ensure that all microorganisms are killed while minimizing any potential damage to the material being sterilized. Studies have shown that ETO sterilization is effective in achieving a high level of microbial kill, with a reduction of up to six logs in microbial populations. However, ETO sterilization has some limitations, including the potential for residual ETO to remain on the sterilized mate...
