  • Patent number: 9926519
    Abstract: Self-adhesive detergent compositions are described including a pH-sensitive color-changing system. The color-changing system is useful with certain acidic compositions and certain alkaline compositions. The compositions have a given color upon application to a hard surface, e.g., a toilet bowl. In one embodiment, when the self-adhesive composition is exposed to a water-based rinse, such as on flushing a toilet, the color-changing system provides the released cleaning portion of the composition, and thereby the water, with a color different from the color of the composition to indicate cleaning is occurring. In another embodiment, following exposure to a plurality of rinses, the color-changing system changes the color of the composition when the composition is near depletion to provide an “end-of-use” cue.

    Abstract: A method for electrolytically generating a biocide having an electron deficient carrier fluid and chlorine dioxide, including providing a carrier fluid; providing a pair of electrodes interposed by a semi-permeable membrane within a vessel for creating a first passageway and a second passageway, an anode electrode of the pair of electrodes disposed in the first passageway, cathode electrode of the pair of electrodes disposed in the second passageway; flowing the carrier fluid through the vessel; applying an electric potential to the pair of electrodes to produce an oxidative acidic fluid, a reductive alkaline fluid, and anodic gases in the container; removing the fluids and gases from the vessel; mixing a portion of the anodic gases with the reductive alkaline fluid to produce a hypochlorite solution; and mixing a chlorite brine with the hypochlorite solution, followed by the introduction of additional oxidative acidic fluid to release the biocide.

  • Patent number: 8323563
    Abstract: An on-demand portable chlorine dioxide generator has a reagent bound medium in a first enclosed volume; a complementary reagent solution in a second enclosed volume, and a structure for selecting between a first position where the complementary reagent solution is forced through the reagent bound medium and a second position where said complementary reagent solution remains isolated from the reagent bound ion exchange medium, where a ClO2 solution is generated only during periods when the structure for forcing is actuated. The ClO2 solution can be discharged for use as a portable sprayer that can be used to treat surfaces infected by anthrax or other biological contaminants. When the bound reagent is chlorite, the complementary reagent is an acid or an oxidant. When the bound reagent is an acid or an oxidant, the complementary reagent solution is a chlorite solution.

  • Patent number: 8262986
    Abstract: The instant invention provides methods and apparatus for disinfecting a space, e.g., a hospital room, using chlorine dioxide. One aspect of the invention provides an apparatus for disinfecting a space. The apparatus includes: a chlorine dioxide gas generator; a sensor adapted and configured to measure the relative pressure inside the space and outside the space; and a computer operatively connected to the sensor and the chlorine dioxide generator, the computer adapted and configured to control the chlorine dioxide generator to operate only when the space is under negative pressure as compared to outside the space. Another aspect of the invention provides a method of disinfecting a space. The method includes: setting an apparatus as described herein in the space; and allowing the apparatus to determine if the space is under negative pressure. If the space is under negative pressure, the apparatus generates chlorine dioxide gas to disinfect the space.

  • Patent number: 8226888
    Abstract: The present invention provides novel viscous and adherent food-safe antimicrobial compositions, and methods for using same in the immediate and residual decontamination of microbial-contaminated substrate surfaces, in reducing or precluding cutting implement-mediated transfer of surface contamination during cutting operations in the food industry, and for reducing or preventing transfer of contamination from contaminated surfaces in the food and pharmaceutical. Adherent antimicrobial protective layers are formed on substrate surfaces (e.g., processing equipment and utensils), providing a barrier (e.g., chemical and/or physical) to the passage or transport of microbial contamination between and among surfaces. The adherent formulations confer residual de-contaminating activity, providing for prolonged killing of associated microbial contamination.

  • Patent number: 8226964
    Abstract: A process for improving a liquid carrying system comprising physically disrupting a biofilm on interior surfaces of the liquid carrying system and then providing molecular iodine onto the disrupted biofilm in a concentration in aqueous material onto the biofilm of at least 10 parts per million. The reactants may be provided before physical disruption also. The molecular iodine may be added in gaseous or liquid or solid state, and may be formed in situ in the interior of the liquid carrier system using available or added water in the reaction.

  • Patent number: 8202548
    Abstract: A method of making a composition having the property of being able to store chlorine dioxide includes mixing an aqueous chlorine dioxide solution with a superabsorbent, water-soluble polymer that is substantially unreactive with chlorine dioxide and permitting a mixture formed thereby to form one of a gel and a solid composition. A method of delivering chlorine dioxide includes providing a gel or solid composition as described and degelling the gel or dissolving the solid composition to dispense the chlorine dioxide therefrom. A method of disinfecting a target such as water, wastewater, or a surface comprises delivering chlorine dioxide as above and permitting the polymer to precipitate out of the mixture. Aqueous chlorine dioxide is then recovered and applied to the target.
