Ethylene oxide sterilization is one of the production processes for sterile products, which aims to ensure that all microorganisms that survive on the sterile packaged products are killed after a sterilization process. At the same time, the product itself and the sterilization packaging that protects the product – the sterile barrier – should not be damaged. Of course, the transport box where the products are placed should not be damaged, and the labels should not be blurry. That is to say, only microorganisms are killed, and other properties must still maintain their original state.
It should be noted that a confirmed sterilization process may not necessarily produce a qualified result, and product sterility is also related to many factors of the product itself. Only when these factors are effectively controlled can the final sterilized product meet the standard requirements.
Before selecting a sterilization supplier, it is necessary to determine the optimal sterilization method. Common sterilization methods include ethylene oxide, gamma ray irradiation, electron beam, and high-pressure steam. The choice of sterilization method needs to consider the product and packaging: 1) the product’s ability to withstand temperature; 2) The ability of the product to withstand humidity; 3) Is the product structure suitable for gas passage; 4) Is the product packaging suitable for gas passage.
