  • Chlorine dioxide generating device
    Patent number: 5091107
    Abstract: The present invention relates to methods and devices for the production of controlled quantities of chlorine dioxide at concentrations which are effective to function as a deodorant or a germicide. Aqueous chlorite compositions such as aqueous sodium chlorite are brought into contact at a controlled rate through capillary means, e.g. a wick with an absorbent pad containing acid or other reactant which will react with the chlorite and form chlorine dioxide.
    Type: Grant
    Filed: October 20, 1989
    Date of Patent: February 25, 1992
    Assignee: The Drackett Company
    Inventor: Richard S. Hutchings
  • Deodorizing and cleaning compositions and method
    Patent number: 5076960
    Abstract: Aqueous deodorizing and cleaning compositions having a pH of from about 4 to 11 containing defined quantities of an alkali metal halogenite together with a salt of a transition or post-transition metal.
    Type: Grant
    Filed: October 23, 1989
    Date of Patent: December 31, 1991
    Assignee: The Drackett Company
    Inventors: Richard S. Hutchings, Mary K. Haber
  • Aqueous alkali metal halogenite compositions
    Patent number: 4963287
    Abstract: Aqueous cleaner compositions containing an alkali metal halogenite, for example, sodium chlorite; a perfume normally chemically incompatible with the halogenite in aqueous media, and a stabilizing amount of an anionic surfactant, the inclusion of which enhances the stability of the perfume-containing aqueous halogenite compositions.
    Type: Grant
    Filed: November 1, 1988
    Date of Patent: October 16, 1990
    Assignee: The Drackett Company
    Inventors: Richard S. Hutchings, Saundra L. Nolte, Jeffrey S. Weaver
  • In-tank toilet dispenser
    Patent number: 4899398
    Abstract: Treatment of water-containing reservoirs with a cleaning composition including a water-dissipatable polyester polymer, the polyester polymer concentration in the reservoir being in an amount effective to capture heavy metal ions, thereby inhibiting staining. In a preferred embodiment, the polyester complexes a perfume, the perfume being released in dilute solution as in the reservoir, whereby a fragrance bloom is provided to the environment.
    Type: Grant

    Assignee: The Drackett Company
    Inventors: Richard S. Hutchings, Carey B. Bottom
  • Aqueous alkali metal halogenite compositions containing a colorant
    Patent number: 4880556
    Abstract: Aqueous cleaner compositions containing an alkali metal halogenite, for example, NaClO.sub.2 ; a stabilizable colorant; and a stabilizing amount of a stabilizer compound selected from the group consisting of alkali metal carbonates, borates and mixtures thereof. The preferred embodiment further includes an anionic or anionic fluorocarbon surfactant.

  • Compositions containing chlorine dioxide and their preparation
    Patent number: 4861514
    Abstract: A chlorine dioxide-containing composition comprising sodium chlorite; an initiator selected from the group consisting of (A) a thickening agent; (B) a colorant, (C) a perfume and mixtures thereof; chlorine dioxide at an antimicrobial concentration, and water, the sodium chlorite and the initiator being present in the composition in an amount adapted to form interactively said antimicrobial chlorine oxide concentration, said composition having a viscosity suitable to maintain the thus-formed chlorine dioxide at a steady-state concentration.
