Abstract
The present invention relates to a biocidal composition, designed for the generation of chlorine dioxide, comprising at least one iodo-compound having at least one iodine atom and a source of chlorite ions. The molar ration of chlorite ions to iodine atoms is 2 or greater. The composition finds use in a variety of applications including methods of cleaning, sanitizing, deodorizing, and disinfecting various surfaces.
Claims43
A biocidal or bleaching composition capable of generating chlorine dioxide comprising:
- a) at least one iodo-compound having at least one iodine atom said iodo-compound selected from the group consisting of an iodine containing interhalide, an iodine containing ionene resin, an organo-iodide, an organic iodophor, and mixtures thereof;
- and
- b) a source of chlorite ions;
- wherein the molar ratio of chlorite ions to iodine atoms is 2 or greater.
A two-part, biocidal or bleaching chlorine dioxide generating composition prepared by mixing a first part and a second part said composition comprising
- in the first part
- i) at least one iodo-compound having at least one iodine atom said iodo-compound selected from the group consisting of an iodine containing interhalide, an iodine containing ionene resin, an organo-iodide, an organic iodophor, and mixtures thereof;
- ii) at least one solvent;
- and
- in the second part
- i) a source of chlorite ions;
- and
- ii) at least one non-acidic solvent;
- wherein the molar ratio of chlorite ions to iodine atoms is 2 or greater after mixing said first part and said second part.
A biocidal or bleaching composition capable of generating chlorine dioxide comprising:
- a) at least one iodo-compound having at least one iodine atom said iodo-compound selected from the group consisting of an iodine containing interhalide, an iodine containing ionene resin, an organo-iodide, an organic iodophor, and mixtures thereof;
- and
- b) a source of chlorite ions at a concentration of more than about 6 wt-% to about 75 wt-%;
- wherein the molar ratio of chlorite ions to iodine atoms is 2 or greater.
A chlorine dioxide-generating composition useful as a biocide, or for bleaching, comprising:
- a) at least one iodo-compound having at least one iodine atom said iodo-compound selected from the group consisting of an iodine containing interhalide, an iodine containing ionene resin, an organo-iodide, an organic iodophor, and mixtures thereof;
- and
- b) a source of chlorite ions;
- wherein said molar ratio of chlorite ions to iodine atoms is 2 or greater for chlorine dioxide generation.
A method for the production of a biocidal or bleaching level of chlorine dioxide comprising the steps of:
- a) providing a source of chlorite ions;
- b) providing at least one iodo-compound having at least one iodine atom said iodo-compound selected from the group consisting of an iodine containing interhalide, an iodine containing ionene resin, an organo-iodide, an organic iodophor, and mixtures thereof;
- wherein the molar ratio of chlorite ions to iodine atoms is 2 or greater;
- and
- c) mixing a sufficient amount of the source of chlorite ions with a sufficient amount of said at least one iodo-compound to produce a biocidal or bleaching level of chlorine dioxide.
