A manufacturer of pre-saturated disinfectant wipes for ISO-classified pharmaceutical and biotech environments needed confidence that every wipe was free from viable bacteria, fungi, and spores. The challenge was ensuring effective sterilization throughout the packaged product without compromising the wipe or its disinfectant formulation. This case study demonstrates how gamma sterilization addressed penetration and microbial-control challenges, helping the manufacturer strengthen sterility assurance for critical cleanroom applications.
