At this point, the disintegrant contained in the tablet begins to swell. This causes the wrapper to increase in volume as a result of the volume increase the tablet abruptly ruptures and releases the tablet. In a non-close fitting

After completion of the rinse cycle, the dishes were visually peeled off on a scale of 1-10. The higher the value, the better the cleaning performance. It can be seen that the formulation according to the invention, which contains both polymers, shows a better cleaning performance on various soils, especially on tea, compared to the comparative formulations, which contain only one of the polymers in each case (Table 3).
