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 0.1 wt. % to about 25 wt. % of a fatty acid amide surfactant; and an enzyme; wherein said composition is pressed to form a solid and further wherein said composition is essentially free of polyethylene glycol and urea thickeners.

2 . (canceled)

3 . The composition of claim 1 wherein said processing aide is an inorganic salt.

4 . The composition of claim 1 wherein said processing aid is a source of alkalinity.

5 . The composition of claim 1 wherein said source of alkalinity is a carbonate.

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

7 . The composition of claim 1 wherein said composition his essentially free of cationic surfactant.

8 . The composition according to claim 4 wherein the inorganic salt comprises acetate salt.

9 . The composition according to claims 1 , wherein the anionic surfactant comprises a alkylsulfonate, alkylarylsulfonate, sulfonated fatty acid ester, sulfated alcohol, sulfated alcohol ethoxylate, sulfated alkylphenol, alkyl sulfate, dialkylsulfosuccinate, alkylethersulfate, and/or mixtures thereof.

10 . The composition of claim 1 wherein said anionic surfactant is a linear alkyl benzene sulfonate.

11 . The composition according to claim 1 , wherein the fatty acid amide surfactant comprises a lauric monoethanol amide, cocomonoethanol amide, and/or mixtures thereof.

12 . The composition of claim 2 wherein said fatty acid amide is cocomonoethanolamide.

13 . The composition according to claim 1 , wherein the composition further comprises an amphoteric surfactant.

14 . The composition according to claim 13 , 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.

15 . The composition according to claim 14 , wherein the amphoteric surfactant comprises cocoamidopropylbetaine.

16 . The composition according to claim 1 , further comprising a chelating agent.

17 . The composition according to claim 1 , further comprising a defoaming agent.

18 . The composition according to claim 1 , further comprising an anti-redeposition agent.

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

20 . 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 0.1 wt. % to about 25 wt. % of a fatty acid amide surfactant; and
an enzyme,
wherein the compositions is essentially free of polyethylene glycol and urea thickeners; and
pressing the composition to form the solid detergent composition.

21 . The method of claim 20 wherein said composition is essentially free of hardening agents.

22 . (canceled)

23 . The method of claim 20 wherein said processing aide is an inorganic salt.

24 . The method of claim 20 wherein said processing aid is a source of alkalinity.

25 . The method of claim 20 wherein said source of alkalinity is a carbonate.

26 . The method of claim 20 wherein said anionic sulfonated surfactant is present in an amount of from about 1 wt. % to about 95 wt. %.

27 . The method of claim 20 wherein said composition is essentially free of cationic surfactant.

28 . The method according to claim 23 , wherein the inorganic salt comprises acetate or sulfate salt.

29 . The method according to claim 20 , wherein the anionic surfactant comprises a alkylsulfonate, alkylarylsulfonate, sulfonated fatty acid ester, sulfated alcohol, sulfated alcohol ethoxylate, sulfated alkylphenol, alkyl sulfate, dialkylsulfosuccinate, alkylethersulfate, and/or mixtures thereof.

30 . The method of claim 29 wherein said anionic surfactant is a linear alkyl benzene sulfonate.

31 . A method according to claim 20 , wherein the fatty acid amide surfactant comprises a lauric monoethanol amide, cocomonoethanol amide, and/or mixtures thereof.

32 . The method of claim 31 wherein said fatty acid amide is cocomonoethanol amide.

33 . The method according to claim 20 , wherein the composition further comprises an amphoteric surfactant.

34 . The method according to claim 33 , 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.

35 . The method according to claim 20 , wherein the composition comprises a bleaching agent.

36 . The method according to claim 20 , further comprising a chelating agent.

37 . The method according to claim 20 , further comprising a defoaming agent.

38 . The method according to claim 20 , further comprising an anti-redeposition agent.

39 . The method according to claim 20 , wherein the solid detergent composition is provided in the form of a block.

40 . A method of cleaning ware including pots and pans comprising: diluting the pressed solid compositions of claim 1 with water to form a use solution, contacting said solution with said ware, and thereafter rising said solution from the ware.

41 . The composition according to claim 1 , further comprising a bleaching agent.
