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) from about 40 wt. % to about 95 wt. % of a neutralized anionic sulfonated surfactant,
(b) a fatty acid amide surfactant comprising at least one of lauric monoethanol amide, cocomonoethanol amide, or a mixture thereof; and
(c) a processing aid including one or more of: an inorganic salt, a source of alkalinity, and/or an acrylic polymer, wherein said composition is pressed to form a solid,

wherein said composition is free of polyethylene glycol and a bleaching agent.

2. The composition of claim 1 wherein said processing aid 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 composition is essentially free of a cationic surfactant.

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

6. 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.

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

8. The composition of claim 1 wherein said fatty acid amide is cocomonoethanolamide.

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

10. The composition of claim 9 , 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.

11. The composition of claim 10 , wherein the amphoteric surfactant comprises cocoamidopropylbetaine.

12. The composition of claim 1 , further comprising a chelating agent, defoaming agent, and/or anti-redisposition agent.

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

14. 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 rising said solution from the ware.

15. The composition of claim 1 , wherein said fatty acid amide surfactant is included in an amount of from about 0.1 wt. % to about 15 wt. %.

16. The method of claim 14 , wherein the ware comprises pots and pans.
