  • Indicator for monitoring a sterilization process
    Patent number: 8512633
    Abstract: The disclosed invention relates to an indicator composition comprising at least one iodide salt, at least one binder, at least one carbonate salt and/or at least one sulfate salt, and at least one antioxidant. The indicator composition may contain at least one dye, complexing agent, inhibitor, and/or solvent. A sterilization indicator comprising the foregoing indicator composition is disclosed. The sterilization indicator may be used for monitoring sterilization processes involving oxidative chemistries.
    Type: Grant
    Filed: August 16, 2007
    Date of Patent: August 20, 2013
    Assignee: American Sterilizer Company
    Inventors: Tricia A. Cregger, Phillip P. Franciskovich, Antoinette Bower, Randal W. Eveland, Michael A. Centanni
  • Oxidative dye composition and indicator
    Patent number: 8481331
    Abstract: An oxidative dye indicator composition comprising an indicator dye that has been pre-reacted with a reducing agent prior to use in an oxidizing or disinfectant sterilizing system. The pre-reacted dye, when subjected to an oxidizing disinfection or sterilization agent, such as peracetic acid or hydrogen peroxide, under goes a visible color change and thus can serve as a chemical, process, or chemical integrator, indicator. The dyes include various azines, thiazines, and oxazines compounds and the reducing agents include alkali metal alkoxides and alkaline earth metal alkoxide compounds.

  • Oxidative dye composition and indicator
    Publication number: 20070054412
    Abstract: An oxidative dye solution comprises an indicating dye that has been reacted with a reducing agent. The pre-reacted dye when subjected to an oxidizing disinfection or sterilization agent such as peracetic acid or hydrogen peroxide under goes a visible color change and thus can serve as a chemical, process, or chemical integrator, indicator. The dyes include various azines, thiazines, and oxazines compounds and the reducing agents include alkali metal alkyloxides and alkaline earth metal alkyloxide compounds.
