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

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

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

4. The compositions of claim 1 , wherein said source of alkalinity is a carbonate.

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

6. The composition of claim 1 , wherein said composition if essentially free of cationic surfactant.

7. The composition of claim 2 , wherein the inorganic salt comprises magnesium salt.

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

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

10. The composition of claim 1 , wherein the fatty acid amide surfactant comprises at least one of lauric monoethanol amide, cocomonoethanol amide, and mixtures thereof.

11. The composition of claim 1 , wherein said fatty acid amide 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 at least one of β-N-alkylaminopropionic acid, N-allyl-β-iminodipropionic acid, imidazoline carboxylate, N-alkylbetaine, N-alkylamidoalkylbetaine, sultaine, amines, and mixtures thereof.

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

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 of cleaning ware comprising: diluting the composition of claim 1 with water to form a use solution, contacting said solution with said ware, and thereafter rinsing said solution from the ware.
