Abstract

Methods of the invention include: (a) providing a solid composition that includes; a rheology modifier, a solidifying agent, and a surfactant; (b) providing a solvent with a first viscosity; and dissolving a portion of the solid composition with the solvent forming a use solution with a second predetermined viscosity, wherein the second predetermined viscosity is greater than the first viscosity.

Claims (66)

1. A method of forming use solutions having vertical cling to surfaces comprising:

a. providing a solid composition comprising;

i. a xanthan;

ii. a urea, polyethylene glycol, phosphate hydrate, or a carbonate hydrate; and

iii. a surfactant;

b. providing a solvent with a first viscosity; and

c. dissolving a portion of the solid composition with the solvent forming a use solution with a second predetermined viscosity, wherein the second predetermined viscosity is greater than the first viscosity.

2. The method of claim 1 , wherein the second predetermined viscosity is at least 30 cps greater than the first viscosity.

3. The method of claim 1 , wherein the second predetermined viscosity is at least 50 cps greater than the first viscosity.

4. The method of claim 1 , further comprising spraying the use solution forming a median airborne particle size of greater than 30 μm.

5. The method of claim 1 , further comprising spraying the use solution forming a median airborne particle size of greater than 70 μm.

6. The method of claim 1 , further comprising spraying the use solution forming a median airborne particle size of greater than 100 μm.

7. The method of claim 1 , wherein the solid composition comprises:

a. 0.1 to 30 wt % rheology modifier comprising xanthan;

b. 1 to 80 wt % solidifying agent comprising urea, polyethylene glycol, phosphate hydrate, or a carbonate hydrate; and

c. 1 to 70 wt % surfactant; all based on total weight of rheology modifer, solidifying agent and surfactant.

8. The method of claim 1 , wherein the solid composition comprises:

0.5 to 10 wt % rheology modifier comprising xanthan;

5 to 40 wt % solidifying agent comprising urea, polyethylene glycol, phosphate hydrate, or a carbonate hydrate; and

10 to 60 wt % surfactant; all based on total weight of rheology modifier, solidifying agent and surfactant.

9. The method of claim 1 , wherein the surfactant is an anionic surfactant, nonionic surfactant cationic, surfactant, amphoteric surfactant, or mixtures thereof.

10. The method of claim 1 , wherein the solid composition further comprises a detergent builder.

11. The method of claim 10 , wherein the builder is a chelating agent.

12. The method of claim 10 , wherein the builder is an acid source.

13. The method of claim 10 , wherein the builder is an alkalinity source.

14. The method of claim 1 , wherein the solid composition further comprises an oxygenated solvent.

15. The method of claim 1 , wherein the oxygenated solvent is an ether, a glycol ether, an alcohol, an alcohol ether, or mixtures thereof.

16. The method of claim 1 , wherein the solid composition further comprises an antimicrobial agent.

17. The method of claim 1 , wherein the solid composition further comprises a bleach, a peracid, a peroxide, a halogen, or mixtures thereof.

18. The method of claim 1 , wherein the solid composition further comprises an enzyme.

19. The method of claim 1 , further comprising forming a stable foam from the use solution.

20. A product formed by the method of claim 1 .

21. A method of forming use solutions having vertical cling to surfaces comprising:

a. providing a soiled surface;

b. providing a solid cleaning composition comprising;

i. a xanthan;

ii. a urea, polyethylene glycol, phosphate hydrate, or a carbonate hydrate; and

iii. a surfactant;

c. providing a solvent with a first viscosity;

d. dissolving a portion of the solid composition with the solvent forming a use solution with a second predetermined viscosity, wherein the second predetermined viscosity is greater than the first viscosity;

e. applying the use solution to the soiled surface in an amount effective to remove the soil from the surface.

22. The method of claim 21 , wherein the surface is soiled with an organic soil.

23. The method of claim 21 , wherein the surface is soiled with an inorganic soil.

24. The method of claim 21 , wherein the surface is soiled with a microorganism.

25. The method of claim 21 , wherein the applying the use solution comprises spraying the use solution forming a median airborn particle size of greater than 30 μm.

26. The method of claim 21 , wherein the applying the use solution comprises spraying the use solution forming a median airborne particle size of greater than 70 μm.

27. The method of claim 21 , wherein the applying the use solution comprises spraying the use solution forming a median airborne particle size of greater than 100 μm.

28. The method of claim 21 , wherein the solid composition comprises:

a. 0.1 to 30 wt % rheology modifier comprising xanthan;
