Detergent tablets, which, in addition to high hardness and extremely short disintegration times, are characterized by high stability against abrasion, can be obtained by introducing surfactant granules into the tablets, the water content of which is at least 5 percent above the water content of the equilibrium moisture content of the same granulate. The water content can be determined by KF titration at 200 ° C, the equilibrium moisture content is achieved by drying the granulate at 80 ° C supply air temperature with a supply air humidity of x <0.015. |
