Abstract

Detergents for dishwashing machines in the form of fused blocks containing alkali metal hydroxides, alkali metal silicates, and from 0.2 to 4% by weight of active chlorine donors having a hydrolysis constant of 3x10-4 or lower (preferably Na- or K-dichloroisocyanurate, Na-dichloroisocyanurate dihydrate, Na-monochloroamido-sulfonate or Na-N-chloro-p-toluene sulfonic acid amide). The process of making the fused blocks comprises heating metasilicate or waterglass solution with or without solid alkali metal hydroxide to 45 DEG to 48 DEG C., allowing the reaction temperature to rise to 60 DEG to 65 DEG C., adding the remaining ingredients including the active chlorine donor at 50 DEG to 65 DEG C., pouring the still liquid melt into flexible molds and allowing it to solidify into blocks therein. The detergent blocks of the invention have good stability to storage and a high dissolving rate in use.
