Abstract

Tablets of active substance, especially detergent and/or decalcifying tablets, contain a dissolution accelerator, which makes the tablets disintegrate on exposure to atmospheric humidity. The novelty is that they contain a desiccant, dispersed in the tablets, which has a crystalline structure in which water can be stored up to a predetermined threshold value to present disintegration.

Description

Wirkstoff-Tabletten als Dosierform für Reiniger- und Entkalkermittel setzen sich in der Praxis immer mehr durch. Ein Grund dafür ist die einfache Dosierung, die kein Abmessen des festen Reiniger- und/oder Entkalkermittels erfordert, was auch aus Umweltschutzgründen zu befürworten ist, da umweltschädigende Überdosierungen vermeidbar sind. Ebenso kommt es nicht zu einem Krümeln, Zusammenbacken oder einem versehentlichen Verschütten, da die Einstückigkeit der Tablette dies in der Regel verhindert.Set active ingredient tablets as a dosage form for detergents and decalcifying agents in practice more and more. One reason for this is the simple dosage, which do not measure the solid detergent and / or descaler requires what is also to be advocated for environmental reasons, because it is environmentally harmful Overdoses are avoidable. It also does not happen to crumble, cake or accidentally spill, since the one-piece tablet usually prevents this.

Nachteilig an den zu einer Wirkstoff-Tablette kompaktierten Feststoffen ist jedoch wegen der verringerten Angriffsoberfläche für das Auflösemedium Wasser die reduzierte Auflösegeschwindigkeit der Inhaltsstoffe. Um diesem Nachteil entgegen zu wirken, ist gemäß dem DE-U-93 14 981 bereits vorgeschlagen worden, den Inhaltsstoffen der Tablette einen sog. Brausekörper (Sprengmittel) beizufügen. Es handelt sich dabei insbesondere um einen Kohlendioxid-Abspalter, beispielsweise in Form von Natriumhydrogencarbonat und/oder Natriumcarbonat, der leicht unter sauren Bedingungen aktivierbar ist, und um eine feste Säure, beispielsweise in Form von Zitronensäure. Ist Wasser zugegen auch in Form von Toilettenspülwasser, beginnt die Reaktion, wobei Kohlendioxid entsteht, welches die Wirkstoff-Tablette desintegrieren läßt. Diese Reaktion ist bei Tabletten überaus wirkungsvoll, da die beiden Reaktanden bedingt durch die komprimierte Herstellform der Tablette sehr eng beieinander sind.
Wegen dieses beschriebenen Wirkprinzips der Brausetablettenkörper ist es verständlich, daß konfektionierte Brausetabletten überaus feuchtigkeitslabil sind. Demgemäß wird für die Wirkstoff-Tabletten eine Verpackung gewählt, die wasserdampfundurchlässig ist, damit die die Wirkstoff-Tablette zersetzende Kohlendioxid-Entwicklung auch nicht in Ansätzen beginnen kann. Herkömmlich verwendete Kunststoffolien als Verpackungsmaterialien sind zwar verwendbar, haben jedoch den Nachteil, daß sie nicht vollständig wasserdampfundurchlässig sind. Vor allem an den Siegelbereichen der Verpackung kann Feuchtigkeit ins Innere gelangen, was die Lagerstabilität der als Brausetablette angelegten Wirkstoffprodukte deutlich erniedrigen kann. Insbesondere bei unvorsichtiger Handhabung kann es sehr leicht zu sog. Bombagen der Verpackung kommen, d.h. insbesondere unter der Luftfeuchtigkeit, die in die Verpackung eindringt oder bedingt ist durch Feuchtigkeit im Rohstoffmaterial, zersetzt sich die Brausewirkstoff-Tablette und aufgrund der damit einhergehenden Volumenvergrößerung platzt die Verpackung auf. Insbesondere bei länger anhaltender Lagerung der Wirkstoff-Tabletten ist dahingehend mit deren Unbrauchbarwerden zu rechnen, so daß diese für einen Verkauf unbrauchbar sind.A disadvantage of the solids compacted into an active ingredient tablet, however, is the reduced dissolution rate of the ingredients because of the reduced attack surface for the dissolving medium water. In order to counteract this disadvantage, it has already been proposed according to DE-U-93 14 981 to add a so-called effervescent substance (disintegrant) to the ingredients of the tablet. 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. This reaction is extremely effective with tablets, since the two reactants are very close together due to the compressed production form of the tablet.
Because of the principle of action of the effervescent tablet body described, it is understandable that prefabricated effervescent tablets are extremely moisture-unstable. Accordingly, a packaging is chosen for the active ingredient tablets which is impermeable to water vapor, so that the carbon dioxide development which decomposes the active ingredient tablet cannot begin to begin with either. Conventionally used plastic films can be used as packaging materials, but have the disadvantage that they are not completely impermeable to water vapor. Moisture can get inside, especially at the sealing areas of the packaging, which can significantly reduce the storage stability of the active ingredient products designed as effervescent tablets. In particular, 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. Particularly if 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.

Durch die DE-A-197 22 832 ist ein Waschmittelformkörper mit verbesserten Auflöseeigenschaften bekannt, wobei Desintegrationsprobleme eines brausemittelhaltigen Wasch- und Reinigungsmittelformkörpers dadurch umgangen werden können, daß zusätzlich zum Sprudelsystem ein quellfähiges, wasserunlösliches Desintegrationshilfsmittel in den Formkörper eingebracht wird, wobei die Formkörper aus einer verdichteten, teilchenförmigen Wasch- und Reinigungsmittelzusammensetzung bestehen und 1 bis 10 Gew.-% eines quellfähigen, wasserunlöslichen Desintegrationshilfsmittels sowie 3 bis 60 Gew.-% eines gasentwickelnden Brausesystems enthalten. Neben den quellfähigen, wasserunlöslichen Desintegrationshilfsmitteln weist der bekannte Wasch- und Reinigungsmittelformkörper eine wasserfreie Substanz Zeolith 4A auf, wobei regelmäßig 1/5 der Gesamtgewichtsmenge dahingehend verwendet ist. Das genannte Zeolith-Material dient bei den bekannten Wasch- und Reinigungsmittelformkörpern zum Einlagern von waschaktiven Substanzen, die sich in das Zeolith-Grundgerüst einlagern und unter dem Einfluß des Waschwassers dann für einen Wasch- und Reinigungsvorgang abgegeben werden. Die Zeolithe dienen also bei den bekannten Lösungen ausschließlich dem Einlagern waschaktiver Reinigungssubstanzen.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.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Lagerstabilität von Wirkstoff-Tabletten mit Brausezusätzen zu erhöhen. Eine dahingehende Aufgabe löst eine Wirkstoff-Tablette mit den Merkmalen des Anspruches 1.Starting from this prior art, the object of the invention based on the storage stability of active ingredient tablets with effervescent additives increase. An active ingredient tablet solves one of these tasks with the Features of claim 1.

Dadurch, daß gemäß dem kennzeichnenden Teil des Anspruches 1 die Wirkstoff-Tablette ein in ihr verteiltes Trocknungsmittel aufweist, das mit einer kristallinen Struktur versehen ist, in der bis zu einem vorgebbaren Schwellenwert zur Vermeidung der Desintegrierung der Tablette Wasser einlagerbar ist, ist es möglich, die Luftfeuchtigkeitsmenge aus der Umgebung "physikalisch" in der Tablette über die kristalline Struktur einzulagern, ohne daß das dahingehende Wasser die Brausezusätze und mithin die Wirkstoff-Tablette schädigt. Es hat sich gezeigt, daß sogar bei Lagerbedingungen, die der Klimazone III entsprechen, also bei einem tropischen Klima mit 75% relativer Luftfeuchtigkeit und 35°C Umgebungstemperatur, die derart modifizierte Wirkstoff-Tablette langfristig lagerbar ist, ohne daß es zu einer schädlichen Desintegrierung ihrer Reaktanden kommt. Characterized in that according to the characterizing part of claim 1 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.

Aufgrund der kristallinen Einlagerungsstruktur wird der Tablette darüber hinaus Stabilität verliehen, d.h. die angesprochene Wassereinlagerung führt nicht zu einer ungewollten Volumenerweiterung des Trocknungsmittels, was ansonsten die Tablette sprengen und derart ihren Zusammenhalt zerstören würde.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.

Als besonders vorteilhaft hat es sich erwiesen, als internes Trocknungsmittel wasserfreie Silikate zu benutzen, deren Kristallstruktur besonders dafür geeignet ist, Wassermoleküle aus der Luftfeuchtigkeit einzulagern. Es ist überraschend, daß das dahingehende Wasser als Initiator der Brausereaktion nicht mehr zur Verfügung steht und für die dahingehende Reaktion erst von außen an die Tablette weiteres Wasser zuzuführen ist.It has proven to be particularly advantageous as an internal drying agent to use anhydrous silicates, the crystal structure of which is particularly suitable is to store water molecules from the air humidity. It’s surprising that the water in question is the initiator of the shower reaction is no longer available and only for the related reaction from more water is to be added to the outside of the tablet.

Als besonders günstig hat es sich erwiesen, wasserfreie Silikate in Form von Zeolithen oder Molsieben zu verwenden.It has proven particularly favorable to use anhydrous silicates in the form of To use zeolites or molecular sieves.

Es ist für einen Fachmann auf dem Gebiet der Wirkstoffsysteme überraschend, daß er mit einem Zeolithgerüststoff, der nur 2 bis 4 Gew.-% der gesamten Tablette einnimmt, vorzugsweise weniger als 3 Gew.-%, Wasser in einem Umfang einlagern kann, daß es nicht zur Desintegrierung der Brausetablette kommt. Im Gegensatz zu bekannten Waschmittelsystemen kommt es mithin auch nicht zu einem gewünschten Aufquellvorgang, sondern die Tablette bleibt in ihrem Volumen und Umfang stabil und unverändert. Mithin stellt die Wirkstofftablette im Sinne der Erfindung ein unterhydrodisiertes Gesamtsystem dar, welches nicht quellfähig ist.It is surprising for a person skilled in the field of active ingredient systems that he with a zeolite builder that only 2 to 4 wt .-% of entire tablet, preferably less than 3 wt .-%, water can store to such an extent that it does not disintegrate the Effervescent tablet is coming. In contrast to known detergent systems there is therefore no desired swelling process, but the tablet remains stable and unchanged in volume and volume. The active ingredient tablet therefore represents an underhydrodized tablet in the sense of the invention Entire system that is not swellable.

Weitere vorteilhafte Ausführungsformen sind Gegenstand der Unteransprüche. Further advantageous embodiments are the subject of the dependent claims.

Die nachfolgende Rahmenrezeptur für eine Wirkstoff-Tablette hat sich in der Praxis als besonders günstig erwiesen, wobei die angesprochenen Phosphate als Sequestiermittel Kalkablagerungen vermeiden.
