Summary: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. Zusammensetzung zur Verwendung in einem Wasserreservoir im Küchen- oder Sanitärbereich, gekennzeichnet durch eine Basiszusammensetzung, die ihre Funktion im wesentlichen nach Zugabe zu einer ersten Wasserbeschickung des Wasserreservoirs entfaltet; und mindestens ein Teilchen, mit mindestens einem Kern, der mindestens eine Substanz umfasst, die ihre Funktion im wesentlichen nach zumindest teilweiser Entleerung der ersten Wasserbeschickung aus dem Wasserreservoir und Zulauf von Frischwasser zu diesem entfaltet, und einer den (die) Kern(e) im wesentlichen vollständig umgebenden Umhüllung, die mindestens eine Verbindung umfasst, deren Löslichkeit mit sinkender Konzentration einer spezifischen Verbindung im umgebenden Medium zunimmt; wobei Mittel vorgesehen sind, um bis zum Zulauf von Frischwasser zum Wasserreservoir eine wesentliche Auflösung der Umhüllung oder eine wesentliche Ablösung der Umhüllung vom Kern (von den Kernen) zu verhindern. The invention relates to a composition for use in a water reservoir in kitchens or sanitary installations, which is characterized in that it consists of a base composition which becomes active substantially after it is added to a first quantity of water placed into the water reservoir; at least one particle having at least one core which contains at least one substance which substantially becomes active after the first quantity of water has been at least partly withdrawn from the water reservoir and fresh water has been added into same; and a coating which substantially fully encloses the core(s) and contains at least one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 to prevent a significant dissolution of the coating or a significant detachment of the coating from the core(s) until fresh water has been added to the water reservoir. L'invention concerne un composition s'utilisant dans un réservoir d'eau dans des cuisines ou des installations sanitaires. Cette composition se caractérise en ce qu'elle comprend une composition de base qui agit sensiblement après avoir été ajoutée à un premier volume d'eau dans le réservoir, et au moins une particule comportant au moins un noyau qui contient au moins une substance qui agit sensiblement après vidange au moins partielle du premier volume d'eau compris dans le réservoir, hors dudit réservoir et après apport d'eau fraîche dans le réservoir, ainsi qu'au moins une enveloppe entourant sensiblement entièrement le(s) noyau(x). Cette enveloppe comprend au moins un composé dont la solubilité augmente dans le milieu ambiant à mesure que la concentration d'un composé spécifique diminue. Il est prévu des moyens pour éviter, jusqu'à l'apport d'eau fraîche dans le réservoir, une dissolution conséquente de l'enveloppe ou une séparation conséquente de l'enveloppe par rapport au(x) noyau(x).
