STERILIZING GAS COMPOSITIONS OF ETHYLENE OXIDE, PENTAFLUOROETHANE AND HEPTAFLUOROPROPANE

摘要

Non-flammable sterilizing gas compositions of ethylene oxide and a flame suppressant comprising pentafluoroethane and heptafluoropropane are useful in the gaseous sterilization of heat and/or moisture sensitive materials. The sterilizing gas compositions are environmentally acceptable and are more efficient and safer to use than conventional sterilant gas mixtures.
