  • Publication number: 20070212256
    Abstract: Provided herein are systems and methods associated therewith for killing molds and reducing other contaminating bioburden that may include bacteria and their spores, yeast, and viruses within various dwellings including homes, office buildings, institutions, and any other enclosed space in which humans reside, either temporarily or permanently. The technology of the present invention can be used to treat vehicles, airplanes, and ships. A process according to the invention includes the generation of a gaseous oxyhalogen species and distribution of the gaseous oxyhalogen species throughout a selected dwelling. It has been unexpectedly found that the concentration level of gaseous oxyhalogen species necessary to kill molds according to the inventive methods is far below that previously recognized in the art as being necessary for the killing of such molds. Thus, mold infestations may be killed in dwellings with minimal disruption to the usual business of the inhabitants.

  • Patent number: 6783767
    Abstract: A powder composition which reacts in water to form in situ peroxycarboxylic acids at an anti-microbially effective concentration. Importantly, its utility is both for topical anti-microbial application and for effective low temperature disinfection/sterilization of instruments. It comprises the combination of a perborate, one or more novel acyl and/or aroyl donors, a buffering system which allows the pH to arise to about 9 for rapid formation of the peroxycarboxylic acids and then drop to about 7.5 for sustained stability and microbial kill. It preferably includes a surfactant facilitating antimicrobial efficacy, as well as other minors.
