Abstract

A solid block detergent composition is described which can be dispensed with a water spray to form an aqueous detergent for cutting and removing grease, removing and suspending soils and rinsing easily leaving cleaned ware. The solid block detergent contains a neutralized sulfonated anionic surfactant in combination with various processing aids to optimize soil removal in a formulation that can be pressed for form a solid.

First claim

What is claimed is:

1. A solid detergent composition comprising:
an effective detersive amount of a neutralized anionic sulfonated surfactant;
a processing aid including one or more of: an inorganic salt, a source of alkalinity, and/or an acrylic polymer;
from about 15 wt. % to about 40 wt. % of a fatty acid amide surfactant; and
an enzyme;
wherein the composition is pressed to form a solid and further wherein the composition is essentially free of polyethylene glycol and urea thickeners.

2. The composition of claim 1 , wherein the processing aid is an inorganic salt.

3. The composition of claim 1 , wherein the processing aid is a source of alkalinity.

4. The composition of claim 1 , wherein the source of alkalinity is a carbonate.

5. The composition of claim 1 , wherein the anionic sulfonated surfactant is present in an amount of from about 1 wt. % to about 95 wt. %.

6. The composition of claim 1 , wherein the composition is essentially free of cationic surfactants.

7. The composition of claim 3 , wherein the inorganic salt comprises an acetate salt.

8. The composition of claim 1 , wherein the anionic sulfonated surfactant comprises an alkylsulfonate, alkylarylsulfonate, sulfonated fatty acid ester, sulfated alcohol, sulfated alcohol ethoxylate, sulfated alkylphenol, alkyl sulfate, dialkylsulfosuccinate, alkylethersulfate, and/or mixtures thereof.

9. The composition of claim 1 , wherein the anionic sulfonated surfactant is a linear alkyl benzene sulfonate.

10. The composition of claim 1 , wherein the fatty acid amide surfactant comprises a lauric monoethanolamide, cocomonoethanolamide, and/or mixtures thereof.

11. The composition of claim 1 , wherein the fatty acid amide surfactant is cocomonoethanolamide.

12. The composition of claim 1 , wherein the composition further comprises an amphoteric surfactant.

13. The composition of claim 12 , wherein the amphoteric surfactant comprises a β-N-alkylaminopropionic acid, N-allyl-β-iminodipropionic acid, imidazoline carboxylate, N-alkylbetaine, N-alkylamidoalkylbetaine, sultaine, amines, and/or mixtures thereof.

14. The composition of claim 13 , wherein the amphoteric surfactant comprises cocamidopropyl betaine.

15. The composition of claim 1 , further comprising a chelating agent.

16. The composition of claim 1 , further comprising a defoaming agent.

17. The composition of claim 1 , further comprising an anti-redeposition agent.

18. The composition of claim 1 , wherein the solid detergent composition is provided in the form of a block.

19. A method for producing a solid detergent composition, the method comprising steps of:
mixing a composition comprising:
an effective detersive amount of a neutralized anionic sulfonated surfactant,
a processing aid including one or more of an inorganic salt, a source of alkalinity, and/or an acrylic polymer;
from about 15 wt. % to about 40 wt. % of a fatty acid amide surfactant; and
an enzyme,
wherein the composition is essentially free of polyethylene glycol and urea thickeners; and

pressing the composition to form the solid detergent composition.

20. The method of claim 19 , wherein the composition is essentially free of hardening agents.

21. The method of claim 19 , wherein the processing aid is an inorganic salt.

22. The method of claim 19 , wherein the processing aid is a source of alkalinity.

23. The method of claim 19 , wherein the source of alkalinity is a carbonate.

24. The method of claim 19 , wherein the anionic sulfonated surfactant is present in an amount of from about 1 wt. % to about 95 wt. %.

25. The method of claim 19 , wherein the composition is essentially free of cationic surfactants.

26. The method of claim 21 , wherein the inorganic salt comprises an acetate salt or a sulfate salt.

27. The method of claim 19 , wherein the anionic sulfonated surfactant comprises an alkylsulfonate, alkylarylsulfonate, sulfonated fatty acid ester, sulfated alcohol, sulfated alcohol ethoxylate, sulfated alkylphenol, alkyl sulfate, dialkylsulfosuccinate, alkylethersulfate, and/or mixtures thereof.

28. The method of claim 27 , wherein the anionic sulfonated surfactant is a linear alkyl benzene sulfonate.

29. A method of claim 19 , wherein the fatty acid amide surfactant comprises a lauric monoethanolamide, cocomonoethanolamide, and/or mixtures thereof.

30. The method of claim 29 , wherein the fatty acid amide surfactant is cocomonoethanolamide.

31. The method of claim 19 , wherein the composition further comprises an amphoteric surfactant.

32. The method of claim 31 , wherein the amphoteric surfactant comprises a β-N-alkylaminopropionic acid, N-allyl-β-iminodipropionic acid, imidazoline carboxylate, N-alkylbetaine, N-alkylamidoalkylbetaine, sultaine, and/or mixtures thereof.

33. The method of claim 19 , wherein the composition further comprises a bleaching agent.

34. The method of claim 19 , further comprising a chelating agent.

35. The method of claim 19 , further comprising a defoaming agent.

36. The method of claim 19 , further comprising an anti-redeposition agent.

37. The method of claim 19 , wherein the solid detergent composition is provided in the form of a block.

38. A method of cleaning ware comprising:
diluting the solid detergent composition of claim 1 with water to form a use solution,
contacting the use solution with the ware, and thereafter
rising the solution from the ware.

39. The composition of claim 1 , further comprising a bleaching agent.
