Abstract: Composition for use in a washing machine, characterized by a basic composition evolving its function essentially in the main washing cycle of the washing machine and in the form of a tablet, and at least one particle with at least one core comprising at least one substance evolving its function essentially in the rinsing cycles, 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 placed in or on the tablet in such a way that the surface of the particle or particles is at the most in partial 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

Abstract: A laundry composition, preferably to be used in addition to a laundry detergent, comprises an acidic peroxidic liquid, and particles suspended in the liquid. The particles comprise a protective coating around a core which includes at least one active ingredient selected from a chelating agent, a dye-transfer inhibitor, an anti-fading agent, an anti-bacterial agent, a fabric softener, a transition metal compound and an optical brightener. The particles are stable in the acidic peroxidic liquid but dissolve or disperse under alkaline washing conditions. Surprisingly incorporation of active ingredient(s) into particles appears to give better washing results than the dissolution of such active ingredients in such a liquid.

Abstract: A water soluble glass is used in dishwashing machines as corrosion protection for glassware. The water soluble glass consists of at least one compound which, in the cleaning and/or rinsing cycles, releases an agent that protects glassware against corrosion. Each of the compounds accounts for no more than 85 molar % of the glass and the solubility of the water soluble glass is defined by a mass loss of at least 0.5 mm under the conditions specified in DIN ISO 719.
Abstract: An apparatus for holding and dispensing metered doses of at least one active composition in a washing machine, a dryer or a dishwasher has at least two separate compartments for respectively receiving and dispensing an active composition and an opening mechanism for the compartments, which is operated by means which are activated by conditions prevailing in the inside of the machine. These conditions prevail solely in the course of a washing, drying or dishwashing cycle. The position of the opening mechanism and/or the compartment(s) after emptying of at least one compartment is changed relative to each other, such that the opening mechanism can then open at least one other compartment, when another activation occurs.

Abstract: An apparatus for holding and dispensing metered doses of an active composition into a washing, drying or dishwashing machine has a supply chamber which holds at least double the amount of an individual dose of the active composition. A dispensing chamber is connected to the supply chamber by a passage in order to receive an individual dose of the active composition and to discharge the composition by way of a discharging passage. The closing of the passage between the supply chamber and the dispensing chamber, either beforehand or simultaneously, is actuated by means which are activated by conditions inside the machine, existing exclusively during a washing, drying or dishwashing cycle. The passage between the supply chamber and the dispensing chamber is re-opened and, beforehand or simultaneously, the discharging passage from the dispensing chamber is closed, so that the dispensing chamber can be re-filled from the supply chamber.

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 said 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.

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.
