Abstract

A solid block or unit dosed detergent composition as described which can be utilized in a variety of applications for cleaning surfaces and objects, removing suspending soils, and rinsing easily. The detergent composition, when exposed to an aqueous solution such as water, dissolves quickly and completely to create the use solution.

First claim

What is claimed is:

1. A method of cleaning comprising:
a) dissolving a solid block, tablet or cast solid detergent composition with water to form a use solution, the composition comprising:
about 20 to about 40 wt. % alkali metal carbonate and about 15 to about 40 wt. % alkali metal hydroxide;
about 20 to about 40 wt. % water; and
at least 0.2 wt. % of a disintegrator comprising a C5 to C8 branched fatty acid
wherein the composition is free of halogen bleaching agents; and

b) applying the use solution to a surface.

2. The method of claim 1 , wherein the surface is located inside a warewashing machine, inside a laundry machine, in a sink, on a floor, inside a fryer, or inside of a food and beverage plant.

3. The method of claim 1 , wherein the surface is selected from the group consisting of a dish, flatware, glass, pot, pan, cooking ware, floor, textile, hard surface, bottle, car, drain, medical instrument, dental instrument, food processing surface, carpet, meat cutting equipment, and a clean-in-place surface.

4. The method of claim 1 , wherein the use solution has a solids content of at least about 0.05 wt. %.

5. The method of claim 1 , wherein the use solution has a solids content of 0.05 wt. % to 5 wt. %.

6. The method of claim 1 , wherein the composition is diluted with water in a ratio of water to detergent of 20:1 to 2000:1.

7. The method of claim 1 , wherein the composition has a dissolution rate when exposed to 4000 mL of aqueous solution at 155° F. of at least 30 g/minute.

8. The method of claim 1 , the composition further comprising an additional ingredient selected from the group consisting of chelating agents, sequestering agents, surfactants, rinse aids, sanitizers, antimicrobial agents, optical brighteners, detergent builders, fillers, defoaming agents, anti-redeposition agents, dyes/odorants, secondary hardening agents, solubility modifiers, pesticides, bait, enzymes, and mixtures thereof.
