Abstract

This invention relates to a wipe for killing spores comprising an absorbent sheet holding an aqueous composition and a sealed package containing the absorbent sheet, wherein the aqueous composition comprises water, an antimicrobial agent and a peroxide. The invention also relates to a process for killing spores using the above-indicated wipe.

First claim

The invention claimed is:

1. A wipe for killing bacterial spores, comprising:
an absorbent sheet holding an aqueous composition for killing the bacterial spores; and
a package containing the absorbent sheet;
wherein the aqueous composition consists essentially of water;
peracetic acid; acetic acid; sulfuric acid; and hydrogen peroxide; wherein the concentration of the peracetic acid is in the range from 0.005 to 0.08% by weight; the concentration of the hydrogen peroxide is in the range from 0.1 to 0.8% by weight; the weight ratio of the peracetic acid to the hydrogen peroxide is in the range from 0.001 to 0.2; the concentration of the acetic acid is in the range from 0.001 to 0.3% by weight; the concentration of the sulfuric acid is in the range from 0.001 to 0.3% the weight.

2. The wipe of claim 1 wherein the absorbent sheet comprises a wiping pad suitable for wiping a substrate.

3. The wipe of claim 1 wherein the absorbent sheet is made of a material that resists disintegration while in use to effect suitable wiping of a substrate.

4. The wipe of claim 1 wherein the absorbent sheet is biodegradable.

5. The wipe of claim 1 wherein the absorbent sheet comprises a woven material, a non-woven material, or a combination thereof.

6. The wipe of claim 1 wherein the absorbent sheet comprises a natural fiber, a synthetic fiber, or a combination thereof.

7. The wipe of claim 1 wherein the absorbent sheet comprises paper, cotton, jute, rayon, polyester, acrylonitrile, nylon, or a combination thereof.

8. The wipe of claim 1 wherein the absorbent sheet comprises a sponge material, polyurethane foam, or a combination thereof.

9. The wipe of claim 1 wherein the absorbent sheet has a surface area of about 5 to about 2000 cm 2 .

10. The wipe of claim 1 wherein the absorbent sheet has a thickness that is sufficient to absorb and retain the aqueous composition.

11. The wipe of claim 1 wherein the absorbent sheet has a thickness in the range from about 0.01 to about 0.5 cm.

12. The wipe of claim 1 wherein the package is square or rectangular in shape.

13. The wipe of claim 1 wherein the package has an air and liquid impermeable construction.

14. The wipe of claim 1 wherein the package has a light impermeable construction.

15. The wipe of claim 1 wherein the package is made of two non-porous sheets with common peripheral edges sealed together.
