Abstract

A composition and method are used to treat articles suspected of contamination with bacterial spores. The composition and method are effective against bacterial spores selected from C. diff., C. botulinum, C. sporogenes, B. cereus , and B. subtilis . The article can be a textile or a hard surface. The method includes preparing a first use solution by mixing ether amine in water and a second use solution by mixing percarboxylic acid in water; applying the first use solution to the article; and applying the second use solution to the article. An alternative method includes preparing a mixture of ether amine, percarboxylic acid, and water, and applying the mixture to the article.

First claim

What is claimed is:

1. A method for eliminating bacterial spores on an article suspected of contamination with bacterial spores, the method comprising:
preparing a first use solution by mixing about 10 to about 2,000 ppm of ether amine in water and a second use solution by mixing about 10 to about 2,000 ppm of percarboxylic acid in water;
applying the first use solution to the article; and
applying the second use solution to the article.

2. The method of claim 1 , wherein the ether amine comprises one or more ether amines having 1-22 carbon atoms.

3. The method of claim 1 , wherein the ether amine comprises one or more ether amines having 10-18 carbon atoms.

4. The method of claim 1 , wherein the first use solution comprises 25-1,500 ppm ether amine.

5. The method of claim 1 , wherein the first use solution comprises 25-1,000 ppm ether amine.

6. The method of claim 1 , wherein the first use solution comprises 50-500 ppm ether amine.

7. The method of claim 1 , wherein the percarboxylic acid comprises one or more percarboxylic acids having 2-12 carbon atoms.

8. The method of claim 1 , wherein the second use solution comprises 10-1,500 ppm percarboxylic acid.

9. The method of claim 1 , wherein the second use solution comprises 50-1,000 ppm percarboxylic acid.

10. The method of claim 1 , wherein the second use solution comprises 50-500 ppm percarboxylic acid.

11. The method of claim 1 , wherein the method is capable of at least 2-log reduction of bacterial spores selected from C. diff, C. botulinum, C. sporogenes, B. cereus , and B. subtilis.

12. The method of claim 1 , wherein the method is capable of at least 3-log reduction of bacterial spores selected from C. diff, C. botulinum, C. sporogenes, B. cereus , and B. subtilis.

13. The method of claim 1 , wherein the method is capable of at least 4-log reduction of bacterial spores selected from C. diff, C. botulinum, C. sporogenes, B. cereus , and B. subtilis.

14. The method of claim 1 , wherein the article comprises a textile or a hard surface.

15. The method of claim 1 , wherein at least one of the first use solution and second use solution further comprises one or more surfactants.

16. The method of claim 1 , wherein at least one of the first use solution and the second use solution further comprises one or more pH modifiers.

17. The method of claim 1 , wherein the first use solution and the second use solution are applied simultaneously to the article.

18. The method of claim 1 , wherein the first use solution and the second use solution are applied consecutively to the article.

19. The method of claim 1 , wherein the first use solution and the second use solution are applied cumulatively to the article.

20. The method of claim 1 , wherein one of the first use solution and the second use solution is a laundry booster.

21. The method of claim 1 , wherein one of the first use solution and the second use solution is applied to a hard surface of the article.

22. The method of claim 21 , wherein one of the first use solution and the second use solution is applied to the article by spraying, pouring, wiping, or mopping.

23. A method for eliminating bacterial spores, the method comprising:
preparing a first use solution by mixing about 10 to about 3,000 ppm of ether amine in water;
preparing a second use solution by mixing about 10 to about 3,000 ppm of percarboxylic acid in water;
applying the first use solution to an article suspected of contamination with bacterial spores;
applying the second use solution the article suspected of contamination with bacterial spores.

24. The method of claim 23 , wherein the first use solution comprises 25-2,000 ppm ether amine.

25. The method of claim 23 , wherein the first use solution comprises 50-1,500 ppm ether amine.

26. The method of claim 23 , wherein the first use solution comprises 50-1,000 ppm ether amine.

27. The method of claim 23 , wherein the second use solution comprises 10-2,000 ppm percarboxylic acid.

28. The method of claim 23 , wherein the second use solution comprises 50-1,500 ppm percarboxylic acid.

29. The method of claim 23 , wherein the second use solution comprises 50-1,000 ppm percarboxylic acid.

30. The method of claim 23 , wherein applying the first use solution comprises immersing the article in the first use solution, and applying the second use solution comprises immersing the article in the second use solution, the method further comprising draining the first use solution before applying the second use solution.

31. The method of claim 23 , wherein the first use solution and the second use solution are applied simultaneously to the article.

32. The method of claim 23 , wherein the first use solution and the second use solution are applied cumulatively to the article.
