  • Patent number: 5935592
    Abstract: A stable solution, cream, salve, or spray composition containing activated chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for the treatment of vaginitis and endometriosis by reducing any of Candida, Actinobacillus actinomycetemcomitans, Pseudomonades, and Porphyromonas gingivalis present in the vagina or the uterus. The preferred concentration ranges are in the range of about 0.005% to about 2.0% of chlorine dioxide, and in the range of about 0.02% to about 3.0% of phosphate. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.4, at which pH chlorine dioxide becomes activated and releases sufficient chlorine dioxide to reduce motility and become lethal to the involved micro-organisms.

  • Patent number: 5935589
    Abstract: The inventive compositions contain an oil-in-water and a water-in-oil emulsion, each buffered to a specific pH, so that the difference in pH values of the two emulsions is at least two units. The molecular mixing is minimized by selecting suitable oil and oil phase in a water-in-oil emulsion. The change in pH is further minimized by buffering each emulsion. The particular advantage of the inventive compositions is the ability to separate within a single composition, with minimal intermixing, active compounds which require different pH environments for stability and/or optimum efficacy.
