Definitions

• a disadvantage of the solids compacted into an active ingredient tablet is the reduced dissolution rate of the ingredients because of the reduced attack surface for the dissolving medium water.
• a so-called effervescent substance disintegrant
• It is in particular a carbon dioxide releaser, for example in the form of sodium hydrogen carbonate and / or sodium carbonate, which can be activated easily under acidic conditions, and a solid acid, for example in the form of citric acid. If water is also present in the form of toilet flushing water, the reaction begins, producing carbon dioxide, which disintegrates the active ingredient tablet.
• careless handling can lead to so-called bombing of the packaging, i.e. especially under the humidity that penetrates the packaging or is caused by moisture in the raw material, the effervescent active ingredient tablet decomposes and the packaging bursts due to the associated increase in volume on.
• the active ingredient tablets are stored for a prolonged period of time, they are likely to become unusable, so that they are unusable for sale.
• DE-A-197 22 832 is a detergent tablet with improved Dissolving properties known, disintegration problems of a effervescent This avoided detergent tablets that in addition to the bubble system, a swellable, water-insoluble disintegration agent introduced into the molded body is, the molded body from a compressed, particulate Detergent and cleaning agent composition consist and 1 to 10 % By weight of a swellable, water-insoluble disintegration aid as well as 3 to 60% by weight of a gas-developing shower system. In addition to the swellable, water-insoluble disintegration aids the known detergent tablets have a water-free one Substance zeolite 4A, regularly 1/5 of the total weight is used to that effect.
• the zeolite material mentioned serves the known detergent tablets for storage of wash-active substances that are embedded in the zeolite framework and then under the influence of the washing water for a washing and Cleaning process.
• the zeolites therefore serve the known solutions exclusively for the storage of washing-active cleaning substances.
• Active ingredient tablet has a desiccant distributed in it that with is provided with a crystalline structure in which up to a predetermined Threshold to avoid disintegration of the water tablet is storable, it is possible to remove the amount of humidity from the environment "physically" in the tablet over the crystalline structure, without the water passing through the shower additives and therefore the Active ingredient tablet damages. It has been shown that even under storage conditions, which correspond to climate zone III, i.e. in a tropical climate with 75% relative humidity and 35 ° C ambient temperature, the such modified active ingredient tablet can be stored long-term without it harmful disintegration of their reactants.
• the tablet Due to the crystalline storage structure, the tablet is placed over it added stability, i.e. the mentioned water retention leads not to an unwanted volume expansion of the drying agent, which otherwise break up the tablet and thus destroy their cohesion would.
