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 is a low-temperature gaseous process used primarily for medical devices, combination products, components, and packaged assemblies that cannot tolerate steam, dry heat, or some radiation processes. EtO can penetrate porous packaging and reach difficult internal locations, including…
Ethylene oxide sterilization validation demonstrates that a defined process consistently delivers the required sterility assurance for approved products and loads while controlling product residuals, material effects, packaging integrity, worker exposure, and environmental emissions. Validation cannot be established from chamber temperature,…
