Abstract
The invention relates to a composition for use in a washing machine. The composition is characterised by a base composition that becomes active essentially during the main wash cycle of the washing machine; and by at least one particle with at least one core which contains at least one substance which becomes active essentially during the rinse cycles of the washing machine and with a coating which essentially fully encloses the core(s) and contains at least one compound whose solubility increases as the concentration of a specific compound in the surrounding medium decreases. The invention provides for means that prevent a significant dissolution of the coating or a significant detachment of the coating from the core(s) until the rinse cycles have begun. The invention also relates to a method for carrying out a wash cycle in a washing machine using the inventive composition.
