ABSTRACT:
A solid cast warewashing composition is produced for use in automatic washing machines at low temperatures. A liquid detergent composition is cast into a mold where it is allowed to solidify. The solid cast detergent, surrounded on all but its upper surface by the mold, is used in automatic washing machines having a dispensing device designed to dispense a liquid aqueous detergent formed from the solid cast detergent using an impinging liquid spray. The liquid aqueous detergent flows out of the dispensing device generally simultaneously with its formation in the dispenser. The cast detergent composition includes about 5 to 12 wt-% of a nonionic surfactant, an alkali metal hydroxide, a sequestrant, water of hydration and optionally further includes one or more preformed cores or plugs comprising an available chlorine source, a defoamer, or the like.
