An article of manufacture comprising a rupturable pouch and an absorbent carrier for reacting a chlorite and an acid to form chlorine dioxide gas.

Chlorine dioxide generator

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.

Chlorine dioxide generating device

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.

Deodorizing and cleaning compositions and method

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.

Aqueous alkali metal halogenite compositions

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.

In-tank toilet dispenser

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.

Aqueous alkali metal halogenite compositions containing a colorant

Aqueous cleaner compositions containing an alkali metal halogenite, for example, NcClO.sub.2 ; a stabilizable colorant; and a stabilizing amount of a stabilizer compound which is an ammonium hydroxide. The preferred embodiment further includes an anionic or anionic fluorocarbon surfactant.

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.

Compositions containing chlorine dioxide and their preparation

Aqueous cleaner compositions containing an alkali metal halogenite, for example, NaClO.sub.2 ; a stabilizable colorant; and a stabilizing amount of a stabilizer compound which is an ammonium hydroxide. The preferred embodiment further includes an anionic or anionic fluorocarbon surfactant.

Cleaning composition and its method of use

A surfactant cleansing block suitable for placement in a toilet tank or other water-containing reservoir, comprising a hydrated cellulosic binder and a surfactant, and processes for making same, especially by extrusion of a homogeneous blend of said binder and said surfactant.
