Alkaline detergent containing mixing organic and inorganic sequestrants resulting in improved soil removal
First Claim
1. A method of cleaning dishware or flatware, the method comprising:
- dissolving a portion of a solid cleaning composition in water by impinging a water spray upon an exposed surface of the composition to form a use solution, the solid cleaning composition consisting of;
alkali metal carbonate;
about 0.1 to about 20 wt-% surfactant;
a sugar;
a material selected from the group consisting of a polycarboxylate, sodium chloride, a starch, a C1-C10 alkylene glycol, sodium sulfate, a dye, a fragrance, and mixtures thereof;
wherein the polycarboxylate is selected from the group consisting of polyacrylic acid, maleic/olefin copolymer, acrylic/maleic copolymer, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed polymethacrylamide, hydrolyzed polyamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile-methacrylonitrile copolymers, and mixtures thereof; and
water;
wherein the solid cleaning composition is a multi-use block having a pinch waist elliptical shape; and
contacting the dishware or flatware with the use solution.

Abstract
Solid block alkaline detergent compositions are disclosed comprising a source of alkalinity, and other detergent additives including sequestrants. The solid block detergents of the invention used a mixed inorganic and organic sequestrant composition that successfully softens service water used in manufacturing aqueous detergents from the composition, but also obtains substantially improved organic soil removal on dishware or flatware. The solid block detergents of the invention comprise large masses of the chemical ingredients having a weight of greater than about 500 grams in a solid block product format that is typically dispensed using a spray on water dispenser that creates an aqueous concentrate that is used in a washing machine.
