Abstract

The present invention is a dimensionally stable solid detergent composition which can be used as a soaking composition. The composition includes a bio-based content of 58% or greater and includes an alkalinity source, a metal protector, a surfactant system, water, a threshold agent, and a polysaccharide hybrid polymer composition. The polymer the polysaccharide hybrid polymer composition includes a polysaccharide residue present in an amount from approximately 5% to 90% by weight of the polysaccharide hybrid polymer composition and a residue of at least one ethylenically unsaturated monomer or salts thereof present in an amount from approximately 10% to 75% by weight of the polysaccharide hybrid polymer composition.

First claim

What is claimed is:

1. A dimensionally stable solid detergent composition comprising
(a) about 30 wt. % to about 80 wt. % alkalinity source;
(b) about 15 wt. % to about 35 wt. % metal protector;
(c) about 2 wt. % to about 10 wt. %, lauryl alcohol ethoxylate;
(d) about 0.1 wt. % to about 20 wt. % water;
(e) about 0.2 wt. % to about 15 wt. % threshold agent; and
(f) a polysaccharide hybrid polymer component,
wherein the dimensionally stable solid detergent composition has a bio-based content of at least 58% or greater.

2. The detergent composition of claim 1 , wherein the polysaccharide hybrid polymer includes a polysaccharide residue present in an amount from approximately 5% to 90% by weight of the polysaccharide hybrid polymer composition and a residue of at least one ethylenically unsaturated monomer or salts thereof present in an amount from approximately 10% to 75% by weight of the polysaccharide hybrid polymer composition.

3. The detergent composition of claim 1 , further comprising a scale inhibitor.

4. The detergent composition of claim 1 wherein said detergent composition may be diluted to form a use solution.

5. The detergent composition of claim 1 , wherein the detergent composition is a pressed solid.

6. The detergent composition of claim 1 wherein said composition includes from about 0.05 wt. % and about 20 wt. % of said polysaccharide hybrid polymer composition.

7. The detergent composition of claim 6 wherein said polysaccharide hybrid polymer composition comprises from about 1 wt. % to about 10 wt. % of said composition.

8. The detergent composition of claim 3 wherein said scale inhibitor is present in an amount of from about 1 wt. % to about 15 wt. %.

9. A dimensionally stable solid detergent composition comprising
(a) an alkalinity source;
(b) a metal protector;
(c) a nonionic low foaming surfactant of lauryl alcohol ethoxylate;
(d) water;
(e) a threshold agent; and
(f) from about 0.05 wt. % and about 20 wt. % of a polysaccharide hybrid polymer composition, wherein the composition has a bio-based content of at least 58% or greater.

10. The detergent composition of claim 9 wherein said alkalinity source is a metal carboxylate.

11. The detergent composition of claim 9 wherein said metal protector is sodium silicate.

12. The detergent composition of claim 9 wherein said scale inhibitor is a citrate.

13. A method of making a dimensionally stable pressed solid soaking composition comprising:
admixing a an alkalinity source; a metal protector; a nonionic low foaming surfactant of lauryl alcohol ethoxylate; water; a threshold agent; and polysaccharide hybrid polymer to form a mixture and
pressing said mixture into a pressed solid composition.

14. The method of claim 13 wherein said mixture is pressed in a die at approximately 1000 pounds per square inch (psi) for approximately 20 seconds to form tablets.

15. The method of claim 13 wherein said solid is dimensionally stable after 4 weeks at 120 degrees F.

16. The method of claim 13 wherein said polysaccharide hybrid polymer includes a polysaccharide residue present in an amount from approximately 5% to 90% by weight of the polysaccharide hybrid polymer composition and a residue of at least one ethylenically unsaturated monomer or salts thereof present in an amount from approximately 10% to 75% by weight of the polysaccharide hybrid polymer composition.

17. The method of claim 13 wherein said solid has a bio-based content of at least 58% or greater.

18. The method of claim 13 wherein said pressed solid is mixed with water to form a use composition.
