Document Type and Number:
WIPO Patent Application WO2000006689
Kind Code:

Abstract:
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at least one substance which substantially becomes active after the first quantity of water has been at least partly withdrawn from the water reservoir and fresh water has been added into same; and a coating which substantially fully encloses the core(s) and contains at least one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.
