  • Patent number: 6800598
    Abstract: Composition for use in a water tank in the kitchen or sanitary sectors 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 Ad 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 substan

  • Patent number: 6730647
    Abstract: A composition is provided for use in a dishwashing machine and in the form of a tablet. The composition is characterized by having at least two small parts, which are placed in or on the tablet, and in which at least one functional substance is concentrated in each case thus enabling the respective small part to be released by dissolution at a determined point in time during the dishwashing cycle. The small parts are produced by using at least two different methods.

  • Patent number: 6727216
    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.

  • Patent number: 6727213
    Abstract: A composition for use in a dishwasher is characterized by a base composition in the form of a tablet which becomes active substantially during the main wash cycle of the dishwasher. At least one separate zone in or on the tablet is provided with a substance that becomes active substantially during the rinse cycle of the dishwasher and with at least one substance that prevents lime scale build-up in the dishwasher and/or on the washed articles. The composition further includes agents that guarantee that at least the substance that becomes active substantially during the rinse cycle of the dishwasher is at least mainly released at the beginning of the rinse cycle at the earliest.
