Estimating the term…
Composition for use in a water tank in the kitchen or sanitary sector, characterized by a basic composition essentially evolving its function following addition to a first water filling of the water tank, in the form of a tablet and at least one particle, with at least one core, which comprises at least one substance evolving its function essentially following an at least partial emptying of the first water filling from the water tank and the inflow of fresh water and a covering substantially completely surrounding the core or cores comprising at least one compound, whose solubility increases with decreasing concentration of a specific ion in the surrounding medium, the at least one particle being so arranged in or on the tablet that the surface of the particle or particles is at most only partly in direct contact with the surface of the basic composition surrounding the same and the concentration of the specific ion in the local environment of the particle or particles is sufficiently high up to a substantially complete dissolving of the tablet in order to prevent a substantial dissolving of the covering or a substantial detachment of the covering from the core or cores.
A composition for use in a water tank, comprising a tablet composition comprising an ionic compound which deploys its function following a first addition of water to the tank, a particle having a core, the core comprising a substance intended to perform its function after a complete or partial emptying of the first addition water from the tank and inflow of fresh water into the tank, and a covering surrounding the core, the covering comprising a compound whose solubility is inversely proportional to a concentration of the ionic compound in a surrounding medium, wherein the particle is arranged in or on the tablet such that only a portion of a surface of the particle directly contacts the tablet, wherein the concentration of the ionic compound caused by dissolution of the tablet is, until the inflow of fresh water into the tank, sufficiently high to prevent dissolution of the covering or detachment of the covering from the core.
