    Abstract: This invention provides a liquid antimicrobial composition that is particularly useful as a mouthwash for treating or reducing the risk of dental disease. The composition is prepared by mixing a first solution comprising a water soluble metal chlorite compound with a second solution comprising sodium persulfate and hydrogen peroxide. The resulting composition, containing chlorine dioxide, is preferably used at the time of preparation by applying the composition to the locus where treatment is desired.

  • Patent number: 6264966
    Abstract: This invention involves the use of a class of compounds with chelation affinity and selectivity for first transition series elements. Application or administration of the free or conjugated compound, or physiological salts of the free or conjugated compound, results in decrease of the bioavailability and/or chemical action of first transition series elements. These characteristics make such compounds useful in cosmetics and personal care products to decrease odor arising from microbial growth on body surfaces and in body cavities, decrease microbial growth on teeth, plaque, and gums that cause tooth decay and gum disease, inhibition of oxidative damage to the skin, inhibition of enzymatic action of metalloenzymes dependent on first transition series elements, and inhibition of reperfusion injury.
