Abstract

A detergent composition, a method of making the detergent composition, and a method of use thereof are provided. The detergent composition comprises at least 0.001% by weight of an antimicrobial agent, based on the total weight of the composition; an enzyme; and at least 0.01% by weight of a hydrotrope, based on the total weight of the composition.

First claim

What is claimed is:

1. A detergent composition comprising:
1% to 5% by weight of an antimicrobial agent, based on the total weight of the composition;
an enzyme; and
at least 1% by weight of a hydrotrope, based on the total weight of the composition,
wherein the composition comprises 0.1% or less by weight of a boron-containing compound, based on the total weight of the composition
wherein the composition comprises 10% or less by weight of a non-ionic surfactant, based on the total weight of the composition.

2. The composition of claim 1 , wherein the hydrotrope comprises an anionic hydrotrope.

3. The composition of claim 2 , wherein the anionic hydrotrope comprises at least one of an alkanoic acid, an aromatic sulfonic acid, an aromatic carboxylic acid, and a salt of any thereof.

4. The composition of claim 3 , wherein the aromatic sulfonic acid is at least one of xylene sulfonic acid, cumene sulfonic acid, and a salt of any thereof.

5. The composition of claim 1 , comprising either no boron-containing compound or only an incidental amount.

6. The composition of claim 1 , wherein the antimicrobial agent comprises at least one of a biguanide compound and a quaternary ammonium compound.

7. The composition of claim 6 , wherein the biguanide compound comprises at least one of chlorhexidine and a salt thereof.

8. The composition of claim 1 , wherein the enzyme comprises at least one of a lipase, a protease, a peptidase, an amylase, a glycosidase, a cellulase, DNAse and a nuclease.

9. The composition of claim 1 , wherein the composition has a pH in a range of 6 to 11.

10. The composition of claim 1 , further comprising at least one of:
at least 0.0001% by weight of a buffer, based on the total weight of the composition, and
at least 0.0001% by weight of a pH adjusting agent, based on the total weight of the composition.

11. The composition of claim 1 , further comprising at least 0.01% by weight of a solvent, based on the total weight of the composition.

12. The composition of claim 11 , wherein the solvent comprises at least one of a glycol ether, propylene glycol, ethylene glycol, methanol, ethanol, isopropanol, and n-propanol.

13. The composition of claim 1 , further comprising at least one of a chelating agent and a salt.

14. The composition of claim 1 , further comprising at least 10% by weight of water, based on the total weight of the composition.

15. The composition of claim 1 , further comprising at least 0.005% by weight of the non-ionic surfactant, based on the total weight of the composition.

16. The composition of claim 15 , wherein the non-ionic surfactant is low foaming.

17. A method of making a detergent composition, the method comprising:
combining, based on the total weight of the composition,
1% to 5% by weight of an antimicrobial agent,
at least 1% by weight of a hydrotrope; and
an enzyme,
wherein the composition comprises 0.1% or less by weight of a boron-containing compound, based on the total weight of the composition
wherein the composition comprises 10% or less by weight of a non-ionic surfactant, based on the total weight of the composition.

18. The method of claim 17 , further comprising adjusting a pH of the detergent composition prior to the adding the enzyme.

19. The method of claim 17 , further comprising adding at least one of a buffer, a chelating agent, a solvent, water, and a salt.

20. A method for cleaning an object, comprising:
applying a detergent composition to the object, the composition comprising, based on the total weight of the composition:
1% to 5% by weight of an antimicrobial agent,
at least 1% by weight of a hydrotrope, and
an enzyme,
wherein the composition comprises 0.1% or less by weight of a boron-containing compound, based on the total weight of the composition,

thereby cleaning the object,
wherein the composition comprises 10% or less by weight of a non-ionic surfactant, based on the total weight of the composition.

21. The method of claim 20 , wherein the object comprises an endoscope.

22. The method of claim 20 , further comprising disinfecting the object.

23. The method of claim 20 , wherein the applying the composition comprises utilizing an automated endoscope re-processor.

24. The method of claim 20 , wherein an operating temperature is from 15° C. to 60° C.
