Abstract
The present invention is directed to frozen biocidal compositions. Specifically, the biocidal compositions comprise a frozen aqueous solution of a plurality of ions selected from the group consisting of halide and oxyhalide ions. The frozen biocidal compositions are useful in preserving or extending the shelf-life of perishable articles.
Claims29
A biocidal composition comprising a frozen aqueous solution, said solution comprising at least one halide ion and at least one oxyhalide ion, wherein the pH of the solution is at least about 6.0.
A method of preserving a perishable article comprising:
- providing a frozen aqueous solution comprising at least one halide and at least one oxyhalide ion and wherein the pH of the composition is at least about 6.0;
- and
- contacting a perishable article with the frozen solution.
A method of preserving a perishable article comprising:
- providing a frozen aqueous solution comprising water, about 0.00075 weight percent to about 0.37 weight percent chlorite ions, about 0.00006 weight percent to about 0.18 weight percent chloride ions, and about 0.000078 weight percent to about 0.039 weight percent chlorate ions and wherein the solution has a pH of at least about 6.0;
- and
- contacting a perishable article with the frozen solution.

- and
- contacting the perishable article with the frozen solution.
A method of preserving a perishable article comprising:
- providing a liquid aqueous solution comprising at least one halide and at least one oxyhalide ion and wherein the pH of the composition is at least about 6.0;
- applying the solution to a perishable article;
- and
- freezing the solution such that the perishable article and the solution are frozen together.
A preserved perishable article comprising:
- a frozen aqueous solution comprising at least one halide ion and at least one oxyhalide ion and wherein the pH of the composition is at least about 6.0;
- and
- a perishable article in contact with said frozen solution.
A preserved perishable article comprising:
- a frozen aqueous solution comprising water, about 0.00075 weight percent to about 0.37 weight percent chlorite ions, about 0.00006 weight percent to about 0.18 weight percent chloride ions, and about 0.000078 weight percent to about 0.039 weight percent chlorate ions and wherein the solution has a pH of at least about 6.0;
- and
- a perishable article in contact with said frozen solution.
