Abstract

Compositions and methods for the treatment of mammalian skin lesions are provided. The compositions contain a protic acid and a chlorite ion, and may be applied topically to a lesion to promote healing. The compositions and methods are particularly useful in the dairy industry for the treatment of bovine hairy heel warts.

Claims

1. A method for treating bovine hairy heel warts, comprising applying to a bovine hairy heel wart an effective amount of an aqueous composition comprising a protic acid and a chlorite ion, wherein the protic acid is present in an amount ranging from about 0.005% to about 5% by weight of the composition, and wherein the chlorite ion is present in an amount ranging from about 0.01% to about 1.0% by weight of the composition.

2. The method of claim 1 wherein the protic acid is an organic acid present in an amount ranging from about 0.05% to about 5% by weight of the composition.

3. The method of claim 2 wherein the organic acid is present in an amount ranging from about 0.1% to about 0.5% by weight of the composition.

4. The method of claim 2 wherein the organic acid is mandelic acid.

5. The method of claim 1 wherein the protic acid is an inorganic acid present in an amount ranging from about 0.005% to about 2% by weight of the composition.

6. The method of claim 1 wherein the chlorite ion is provided by a metal chlorite.

7. The method of claim 6 wherein the metal chlorite is sodium chlorite.

8. The method of claim 1 wherein the composition further comprises an agent selected from the group consisting of a wetting agent, a film forming agent, an alcohol, a wound-healing agent, a preservative and a colorant.

9. The method of claim 1 wherein the wound-healing agent is a copper-containing compound.

10. The method of claim 9 wherein copper is present in the composition in an amount ranging from 100 ppm to 4000 ppm.

11. The method of claim 1 wherein the application is by spraying.

12. The method of claim 1, further comprising the step of mixing a first phase and a second phase prior to applying the composition to the bovine hairy heel wart, wherein the first phase comprises the protic acid and the second phase comprises the chlorite ion.
