ABSTRACT:
Water-based chemical indicator inks for ethylene oxide sterilization processes and methods for its use. The chemical indicator ink contains at least one pH indicator dye selected from the group consisting of Bromocresol green, Bromophenol blue, Methyl red, Ethyl orange, and combinations thereof. The pH indicator dye undergoes an irreversible color change when exposed to ethylene oxide vapor in the presence of low-temperature steam, but when exposed to other sterilization processes either does not undergo a color change or undergoes a color change that is different than is obtained when exposed to ethylene oxide.
