Abstract

The present invention relates to compositions including surfactant peroxycarboxylic acid, methods for making these compositions, and methods for reducing the population of a microorganism.

First claim

We claim:

1. A composition comprising:
an effective antimicrobial amount of surfactant peroxycarboxylic acid, wherein the surfactant peroxycarboxylic acid comprises anionic surfactant peroxycarboxylic acid, amphoteric surfactant peroxycarboxylic acid, zwitterionic surfactant peroxycarboxylic acid, or mixture thereof; wherein the surfactant peroxycarboxylic acid comprises one or more of an alkyl carboxylate moiety, an alkyl amide moiety, an alkyl sulfonate moiety, an ethoxylate moiety, or a propoxylate moiety;
about 0.0005 to about 40 wt-% carboxylic acid surfactant;
an oxidizing agent; and
about 20 wt-% to 70 wt-% of an acidulant.

2. The composition of claim 1 , comprising: about 0.0005 to about 15 wt-% surfactant peroxycarboxylic acid; and about 0.0005 to about 25 wt-% carboxylic acid surfactant.

3. The composition of claim 1 , wherein the oxidizing agent comprises about 0.0005 to about 50 wt-% of the composition.

4. The composition of claim 1 , wherein the acidulant comprises about 30 wt-% to about 70 wt-% of the composition.

5. The composition of claim 1 , further comprising about 0.00002 to about 10 wt-% stabilizing agent.

6. The composition of claim 1 , further comprising about 5 to about 99.9999 wt-% carrier.

7. The composition of claim 1 , wherein the surfactant peroxycarboxylic acid is selected from the group consisting of an alcohol ethoxy peroxycarboxylic acid, a sulfo peroxysuccinic acid, an alkylamine peroxycarboxylic acid, or mixture thereof.

8. The composition of claim 7 , wherein the surfactant peroxycarboxylic acid comprises an alcohol ethoxy peroxycarboxylic acid.

9. The composition of claim 8 , Wherein the surfactant peroxycarboxylic acid comprises a linear alcohol ethoxy peroxycarboxylic acid.

10. The composition of claim 7 , wherein the surfactant peroxycarboxylic acid comprises sulfo peroxysuccinic acid.

11. The composition of claim 10 , wherein the surfactant peroxycarboxylic acid comprises laurethsulfoperoxysuccinic acid.

12. The composition of claim 7 , wherein the surfactant peroxycarboxylic acid comprises an alkylamine peroxycarboxylic acid.

13. The composition of claim 12 , wherein the surfactant peroxycarboxylic acid comprises alkyliminodipropionate peroxycarboxylic acid.

14. The composition of claim 13 , wherein the surfactant peroxycarboxylic acid comprises linear alcohol ethoxy peroxycarboxylic acid, laurethsulfoperoxysuccinic acid, alkyliminodipropionate peroxycarboxylic acid, or mixture thereof.

15. The composition of claim 1 , wherein the carboxylic acid surfactant comprises an anionic surfactant, an amphoteric surfactant, a zwitterionic surfactant, or a mixture thereof.

16. The composition of claim 15 , wherein the carboxylic acid surfactant comprises an alcohol ethoxycarboxylate.

17. The composition of claim 16 , wherein the carboxylic acid surfactant comprises a linear alcohol ethoxycarboxylate.

18. The composition of claim 15 , wherein the carboxylic acid surfactant comprises sulfosuccinate.

19. The composition of claim 18 , wherein the carboxylic acid surfactant comprises laurethsulfosuccinate.

20. The composition of claim 15 , wherein the carboxylic acid surfactant comprises an alkylaminecarboxylate.

21. The composition of claim 20 , wherein the carboxylic acid surfactant comprises alkyliminodipropionate.

22. The composition of claim 15 , wherein the carboxylic acid surfactant comprises linear alcohol ethoxycarboxylate, laurethsulfosuccinate, alkyliminodipropionate, or mixture thereof.

23. A method of reducing population of microorganism on an object, the method comprising:
contacting the object with a surfactant peroxycarboxylic acid composition;
the composition comprising:
an effective antimicrobial amount of surfactant peroxycarboxylic acid, wherein the surfactant peroxycarboxylic acid comprises anionic surfactant peroxycarboxylic acid, amphoteric surfactant peroxycarboxylic acid, zwitterionic surfactant peroxycarboxylic acid, or mixture thereof;
about 0.0005 to about 40 wt-% of a carboxylic acid surfactant;
an oxidizing agent; and

about 20 wt-% to 70 wt-% of an acidulant.

24. An article of manufacture comprising:
a first composition comprising carboxylic acid surfactant and carrier;
a second composition comprising oxidizing agent;
directions for combining the first and second compositions;
wherein combining the first and second compositions provides a surfactant peroxycarboxylic acid composition:
the surfactant peroxycarboxylic acid composition comprising:
an effective antimicrobial amount of surfactant peroxycarboxylic acid, wherein the surfactant peroxycarboxylic acid comprises anionic surfactant peroxycarboxylic acid, amphoteric surfactant peroxycarboxylic acid, zwitterionic surfactant peroxycarboxylic acid, or mixture thereof;
about 0.0005 to about 40 wt-% of the carboxylic acid surfactant;
an oxidizing agent; and
about 20 wt-% to 70 wt-% of an acidulant.
