Abstract
A method of manufacturing a solid cast detergent composition comprising the steps of introducing a solid particulate detergent-component into a mold wherein the particulate defines an interstitial void volume; introducing into the mold, in the absence of substantial agitation, an effective interstitial void volume occupying amount of an aqueous solution of a hydratable alkaline chemical; allowing the aqueous solution to percolate the detergent-component particles; and solidifying the aqueous solution. The preferred detergent-component is a condensed phosphate and the preferred alkaline-chemical is sodium hydroxide.
