Abstract

The present invention relates to compositions including medium chain peroxycarboxylic acid, methods for making these compositions, and methods for reducing the population of a microorganism. The compositions can include advantageously high levels of the medium chain peroxycarboxylic acid, can be readily made, and/or can exhibit reduced odor.

First claim

The invention claimed is:

1. A composition comprising:
about 0.5 to about 5 wt % medium chain peroxycarboxylic acid;
about 1 to about 10 wt % medium chain carboxylic acid;
about 10 to about 80 wt % water; and
at least 5 parts of an oxidizing agent for every part of the medium chain peroxycarboxylic acid
wherein the composition is free of short-chain carboxylic acids having 4 or fewer carbon atoms.

2. The composition of claim 1 , wherein medium chain comprises from five to twelve carbon atoms.

3. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxypentanoic acid and the medium chain carboxylic acid comprises pentanoic acid.

4. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxyhexanoic acid and the medium chain carboxylic acid comprises hexanoic acid.

5. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxyheptanoic acid and the medium chain carboxylic acid comprises heptanoic acid.

6. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxyoctanoic acid and the medium chain carboxylic acid comprises octanoic acid.

7. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxynonanoic acid and the medium chain carboxylic acid comprises nonanoic acid.

8. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxydecanoic acid and the medium chain carboxylic acid comprises decanoic acid.

9. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxyundecanoic acid and the medium chain carboxylic acid comprises undecanoic acid.

10. The composition of claim 1 , wherein the medium chain peroxy carboxylic acid comprises peroxydodecanoic acid and the medium chain carboxylic acid comprises dodecanoic acid.

11. The composition of claim 1 , wherein the oxidizing agent is hydrogen peroxide.

12. The composition of claim 1 further comprising about 1 to about 20 wt % of a surfactant.

13. The composition of claim 12 , wherein the surfactant is an anionic surfactant.

14. The composition of claim 1 , wherein the composition has a pH of about 3 or less.

15. The composition of claim 1 further comprising about 15 to about 35 wt % inorganic acid.

16. The composition of claim 1 , wherein the composition is in the form of a microemulsion.

17. The composition of claim 1 further comprising a solvent as solubilizer.
