Abstract

Detergent compositions are disclosed which provide superior cleaning and removal of proteinaceous and starchy soils. Applicants have discovered a surfactant package which acts to enhance and improve the performance of enzymes such as proteases and/or amylases. Compositions for pot and pan warewash detergents and soaks are disclosed, as well as their use in manual or dish machine cleaning.

First claim

What is claimed is:

1. An enzyme surfactant component for inclusion in a detergent composition that optimizes the cleaning ability of the enzyme comprising:
from about 0.01 wt. % to about 20 wt. % of a protease and an amylase enzyme;
from about 5 wt. % to about 45 wt. % of a sodium olefin sulfonate and a sodium lauryl ether sulfate present in a weight ratio of about 4 parts of said sodium olefin sulfonate to about 1 part of said sodium lauryl ether sulfate;
from about 0.01 wt. % to about 25 wt. % of a nonionic surfactant and one or more amphoteric surfactants, wherein the nonionic surfactant comprises a branched secondary alcohol ethoxylate surfactant and/or an alcohol alkoxylate containing both ethylene oxide and propylene oxide polymer segments,
wherein said component is free of alkyl benzene sulfonate.

2. The enzyme surfactant component of claim 1 wherein said amphoteric surfactants comprise an amine oxide and/or cocamidopropyl betaine.

3. The enzyme surfactant component of claim 1 wherein said amphoteric surfactant comprises both an amine oxide and a cocamidopropyl betaine.

4. The enzyme surfactant component of claim 1 wherein said alcohol alkoxylate is a 2 ethyl hexyl PO 4-8 EO 3, 6, 9, or 14 .

5. The enzyme surfactant component of claim 1 further comprising a Guerbet alcohol ethoxylate.

6. The enzyme surfactant component of claim 1 wherein said branched secondary alcohol ethoxylate is a polyethylene glycol trimethyl nonyl ether.

7. A detergent comprising the enzyme surfactant component of claim 1 .

8. The detergent of claim 7 wherein said detergent further comprises an enzyme stabilizer.

9. The detergent of claim 7 further comprising a preservative.

10. The detergent of claim 7 further comprising a viscosity enhancer.

11. The detergent of claim 7 further comprising one or more additional components of dye, fragrance, water, an alkalinity source, a chelant, additional enzyme, a dispersant, a bleaching agent, or a defoaming agent.

12. The detergent of claim 7 wherein said detergent is in liquid form.

13. A warewash/soak detergent composition comprising:
from about 0.01 wt. % to about 20 wt. % of a protease and an amylase enzyme;
from about 5 wt. % to about 45 wt. % of anionic surfactant, comprising sodium olefin sulfonate and sodium lauryl ether sulfate present in a ratio of about 4 parts of said sodium olefin sulfonate to about 1 part of said sodium lauryl ether sulfate;
from about 0.01 wt. % to about 25 wt. % of a nonionic and an amphoteric surfactant, wherein the nonionic surfactant comprises one or more of a branched secondary alcohol ethoxylate surfactant and/or an alcohol alkoxylate containing both ethylene oxide and propylene oxide polymer segments;
with the remainder comprising one or more of water, an enzyme stabilizer, a viscosity enhancer, a preservative, fragrance and dye, wherein the detergent composition is free of linear alkyl benzene sulfonate.

14. The warewash/soak detergent composition of claim 13 further comprising an enzyme stabilizer of propylene glycol.

15. The warewash/soak detergent composition of claim 13 further comprising a viscosity control agent of sodium chloride.

16. The warewash/soak detergent composition of claim 13 wherein said protease is one or more of a serine protease, cysteine protease, carboxyl protease and/or metalloprotease.

17. The warewash/soak detergent composition of claim 13 further comprising wherein said protease is bacteria-, actinomycete-, mold- or yeast-derived protease.

18. The warewash/soak detergent composition of claim 13 wherein said protease is a bacterial protease.

19. The warewash/soak detergent composition of claim 13 wherein said amylase is derived from a yeast, a mold, or a bacterium.

20. The warewash/soak detergent composition of claim 13 wherein said amylase is derived from Bacillus , including B. licheniformis, B. amyloliquefaciens, B. subtilis , or B. stearothermophilus.

21. The warewash/soak detergent composition of claim 13 wherein said composition is a concentrate composition to be diluted at the point of use.

22. A method of cleaning proteinaceous or starchy soils:
applying the detergent composition according to claim 13 to a ware surface in a sink and/or prior to cleaning in a dish machine; and there after rinsing said ware, wherein said detergent provides improved protein or starchy soil removal and acceptable foaming for manual dish washing performance.

23. The method of claim 22 wherein said detergent is a ready to use solution.

24. The method of claim 22 wherein said dish machine is an institutional dish machine.

25. The method of claim 22 wherein said dish machine is a clean in place machine.

26. An enzyme surfactant component for inclusion in a detergent composition that optimizes the cleaning ability of the enzymes comprising:
from about 0.01 wt. % to about 20 wt. % of a protease and an amylase enzyme;
from about 5 wt. % to about 45 wt. % of a sodium olefin sulfonate and a sodium lauryl ether sulfate present in a ratio of about 4 parts of said sodium olefin sulfonate to about 1 part of said sodium lauryl ether sulfate;
from about 0.01 wt. % to about 25 wt. % of one or more of amine oxide, and/or cocoamidopropyl betaine, wherein the nonionic surfactant comprises a branched secondary alcohol ethoxylate surfactant and/or an alcohol alkoxylate containing both ethylene oxide and propylene oxide polymer segments,
wherein said component is free of alkyl benzene sulfonate.

27. The component of claim 26 wherein said alcohol alkoxylate is a 2 ethyl hexyl PO 4-8 EO 3, 6, 9, or 14 .

28. The component of claim 26 further comprising a Guerbet alcohol ethoxylate.

29. The component of claim 26 wherein said branched secondary alcohol ethoxylate surfactant is polyethylene glycol trimethyl nonyl ether.
