Abstract
The invention provides a process for preparing a highly alkaline, solid cleaning composition in a batch or continuous mixing system, at or below the melting temperature of the alkaline ingredients, and products produced by the process. Preferably, the ingredients are processed in an extruder, and the mixture is extruded directly into a mold or other packaging system for dispensing the cleaning composition. The consistency of the product ranges from that of a fused block solid to a malleable product. The highly alkaline cleaning compositions are useful for warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, laundry detergents, and the like.
