This section addresses the principles and validation of ethylene oxide sterilization processes used for temperature- and moisture-sensitive materials. It covers process parameters, load configuration, aeration requirements, biological indicator use, and validation strategy to ensure effective microbial inactivation and controlled residual levels in accordance with regulatory expectations.
Ethylene oxide sterilization validation demonstrates that a defined sterilization process consistently achieves the required Sterility Assurance Level under worst-case, controlled conditions. Because EtO sterilization is a multi-variable chemical process involving gas concentration, humidity, temperature, time, and load configuration, validation must…
Ethylene Oxide EtO sterilization is a low-temperature gaseous sterilization method widely used for heat- and moisture-sensitive medical devices and combination products. It remains an established, regulator-accepted technology for complex devices with long lumens, mixed materials, electronics, and polymers that cannot…
