In order to produce dishwashing detergent containing alkali hydroxide and active chlorine for the automatic cleaning of dishes, a melt of alkali silicates, alkali hydroxides and optionally water is heated to 50 to 75 ° C. by cooling or heating and a chlorine-active compound at a controlled temperature of 70 to 75 ° C. e.g. B. chlorinated isocyanuric acid derivatives, Na monochloramidosulfonate, N-chloro-p-toluenesulfonamide sodium, incorporated, and organic complexing agents. The melt obtained is then mixed together in a continuous mixer together with a) coarse-grained and granular pentaalkali phosphate (a: b = 6: 1 - 2: 1) and possibly other components in a continuous mixer, poured into molds and added Let blocks solidify, which are composed uniformly and are stable in storage. |
