The invention relates to a dimensionally stable, single-piece detergent or treatment agent portion having a weight of at least 50g, comprising a system for controlling the solubility of the detergent or treatment agent which has the effect that in the washing, treating or rinsing cycles of a washing machine for textiles, that are carried out with water (town water, 16°d) at a maximum temperature of 20°C, a maximum 50wt.%, preferably a maximum of 40wt.%, more preferably a maximum of 30 wt.% and in particular, a maximum of 20 wt.% of the amount of the detergent or treatment agent portion dissolved or dispersed in each cycle. In otherwise identical conditions, said portion, in the same proportions, is dissolved or dispersed in water (town water, 16°d) at a temperature of 50°C, thus enabling the targeted release of the active substances contained in said portion during the cycles of a washing or treating programme, carried out with heated water. |
