Es ist den Fachmann bekannt und durch den zitierten Stand der Technik dokumentiert, daß wasserenthärtende waschmitteladditive bislang in möglichst kleinteiliger, vorzugsweise Pulverform, allenfalls in Granulatform angeboten werden, da die Meinung bestand, daß nur dadurch die erforderliche schnelle Löslichkeit eines Wasserenthärters gewährleistet werden kann.It is known in the art and by the cited state of Technique documents that water-softening detergent additives so far in the smallest possible particle size, preferably powdered form,  possibly offered in granular form, as the opinion was that only by the required rapid solubility a water softener can be guaranteed.

Die Anmelderin hat sich zur Aufgabe gesetzt, einen Wasserenthärter mit Buildereigenschaften in leicht handhabbarer, gut dosierbarer Form zur Verfügung zu stellen.The Applicant has set itself the task of a water softener with builder properties in easy to handle, well dosed To provide form.

Erfindungsgemäß wird dies durch ein wasserlösliches, wasserenthärtendes Mittel mit Buildereigenschaften zur Verwendung in einer Waschlauge in Form einer schnell sich auf lösenden Tablette erreicht, wobei die Tablette eine bestimmte Zusammensetzung aufweist, die einerseits eine gute Handhabbarkeit der Tablette, andererseits eine schnelle Auflösung der Tablette in der Waschlauge gewährleistet. According to the invention, this is achieved by a water-soluble, water softening agent with builder properties for use in a wash liquor in the form of a rapidly dissolving one Tablet is reached, the tablet being a specific Composition, on the one hand good handling the tablet, on the other hand, a rapid dissolution of the tablet in the wash liquor ensured.  

Das erfindungsgemäße wasserlösliche, wasserenthärtende Mittel in Form einer Tablette besteht ausThe water-soluble, water-softening agent according to the invention in the form of a tablet consists of

  • A) 60-98 Gew.-% einer Kombination ausA) 60-98 wt .-% of a combination of
  • a) Citrat und/oder Citronensäure unda) citrate and / or citric acid and
  • b) einem als Enthärter wirksamen Polymerb) a polymer which acts as a softener

in einem Gewichtsverhältnis von a:b von 70 : 30 bis 50 : 50, vorzugsweise 65 : 35 bis 55 : 45,in a weight ratio of a: b of 70:30 to 50:50, preferably 65:35 to 55:45,

  • B) 0,5-6 Gew.-% PolyethylenglykolB) 0.5-6 wt .-% polyethylene glycol
  • C) 0-38 Gew.-% weiterer Hilfsstoffe.C) 0-38 wt .-% of other auxiliaries.

Die erfindungsgemäß in Kombination mit Citrat und/oder Citronensäure einzusetzenden, als Enthärter wirksamen Polymeren sind bekannte Substanzen. Hierfür eignen sich Maleinsäure/Acrylsäure-Copolymerisate und vorzugsweise biologisch abbaubare Polymere, insbesondere solche auf Peptid-Basis. Solche Polymere auf Peptid-Basis sind beispielsweise die Cygnus-Produkte der Cygnus Corporation. Als Builder geeignete Serin-N-N-Diessigsäurederivate werden in der EP 287 885 beschrieben.The invention in combination with citrate and / or Citric acid to be used, effective as a softener Polymers are known substances. Suitable for this purpose Maleic acid / acrylic acid copolymers and preferably biodegradable polymers, especially those on Peptide-based. Such peptide-based polymers are For example, the Cygnus products of Cygnus Corporation. Suitable builders are serine N-N-diacetic acid derivatives in EP 287 885.

Als Builder geeignete Maleinsäure/Acrylsäure-Copolymerisate sind unter verschiedenen Marken im Handel, beispielsweise ein Maleinsäure/Acrylsäure-Copolymerisat, Natriumsalz.As builder suitable maleic acid / acrylic acid copolymers are under different brands in the trade, for example, a maleic acid / acrylic acid copolymer, Sodium salt.

Ein wesentlicher Bestandteil der erfindungsgemäßen Tabletten stellt das Polyethylenglykol dar, welches in einer Menge von 0,5-6 Gew.-%, vorzugsweise 1-3 Gew.-%, anwesend sein sollte. Als geeignete Polyethylenglykole sind die Polyethylenglykole (1000-6000) zu nennen, insbesondere Polyethylenglykol (4000-6000). Diese Polyethylenglykole wirken als Tablettierungshilfsmittel. Daß Polyethylenglykol als Tablettierungshilfsmittel brauchbar ist, war bekannt. Jedoch ergab sich überraschenderweise, daß, während bei anderen Tablettierungshilfsmitteln Auflösungsschwierigkeiten sich ergaben, die genannten Polyethylenglykole für den erfindungsgemäßen Zweck vorzüglich geeignet sind.An essential part of the invention Tablets represents the polyethylene glycol, which in in an amount of 0.5-6% by weight, preferably 1-3% by weight should be. Suitable polyethylene glycols are the Polyethylene glycols (1000-6000), in particular Polyethylene glycol (4000-6000). These polyethylene glycols act as tableting aids. That polyethylene glycol  was useful as a tabletting aid was known. However, it has surprisingly been found that while other tabletting aids dissolution difficulties showed, the said polyethylene glycols for the Purpose of the invention are excellent.

Ein Polyethylenglykol mit niederem Ethoxylierungsgrad, beispielsweise Polyethylenglykol 200, eignet sich nicht als Tablettierungsmittel, wohl aber als Staubbindemittel und kann als solches in der erfindungsgemäßen Tablette ebenfalls in geringer Menge, beispielsweise in einer Menge von 0,5-5 Gew.-%, anwesend sein.A polyethylene glycol with a low degree of ethoxylation, for example, polyethylene glycol 200, is not suitable as Tabletting agent, but probably as a dust binder and can as such in the tablet according to the invention also in small amount, for example in an amount of 0.5-5 Wt .-%, to be present.

Die erfindungsgemäße Tablette sollte ein Sprengmittel enthalten. Als solches eignet sich ein unlösliches Polyvinylpyrrolidon, welches in einer Menge von 1-20 Gew.-%, vorzugsweise 7-12 Gew.-%, vorliegen kann.The tablet of the invention should be a disintegrant contain. As such, an insoluble is suitable Polyvinylpyrrolidone which is present in an amount of 1-20% by weight, preferably 7-12 wt .-%, may be present.

Es wird jedoch besonders bevorzugt in der Builderkombination (A) Citronensäure und/oder teilneutralisiertes, sauer wirkendes Polymer einzusetzen und als weiteren Hilfsstoff Carbonat und/oder Bicarbonat, beispielsweise Natriumcarbonat, Natriumhydrogencarbonat und/oder Kaliumcarbonat, welches in Kombination mit der vorerwähnten sauren Komponente als Sprengmittel dient. Das Carbonat/Bicarbonat kann in Mengen von 5-30 Gew.-% eingesetzt werden.However, it is particularly preferred in the builder combination (A) citric acid and / or partially neutralized, acidic to use acting polymer and as another excipient Carbonate and / or bicarbonate, for example sodium carbonate, Sodium bicarbonate and / or potassium carbonate, which in Combination with the aforementioned acidic component as Blasting agent is used. The carbonate / bicarbonate can be used in quantities from 5 to 30% by weight.

Vorzugsweise stellen die in der erfindungsgemäßen Kombination (A) genannten Builder die einzigen Builder in der Tablette dar. Zeolithe werden vorzugsweise nicht mitverwendet, obwohl gegebenenfalls die Tablette 5-20 Gew.-% eines Schichtsilikates enthalten kann, was den Builder besonders geeignet macht für hartes Wasser mit hohen Anteilen Magnesiumhärte.Preferably, those in the inventive combination (A) Builder the only builder in the tablet Zeolites are preferably not included, although optionally the tablet 5-20 wt .-% of a phyllosilicate which makes the builder particularly suitable for Hard water with high levels of magnesium hardness.

Als weitere Hilfsmittel zusätzlich zu den bereits genannten können beispielsweise Cellulosederivate, wie Methylhydroxy­ ethylcellulose, oder Paraffinöl in geringen Mengen mit­ verwendet werden.As a further aid in addition to those already mentioned For example, cellulose derivatives such as methylhydroxy  ethylcellulose, or paraffin oil in small amounts with be used.

Eine bevorzugte Builder-Tablette gemäß vorliegender Erfindung enthält:
16-40 Gew.-%, vorzugsweise 18-35 Gew.-% Trinatriumcitrat,
14-21 Gew.-%, vorzugsweise 17-19 Gew.-% Citronensäure,
