"Haushaltsmittel in Tablettenforn""Budget in tablet form"

Die Erfindung betrifft ein Haushaltsmittel in Tablettenforin zur'Entfernung von Kalkrückständen, das ferner dessen genaue Dosierung ermöglicht.The invention relates to a household agent in tablet form zur'Entfernung von Lime residues, the further its exact Dosing enabled.

Die Entfernung von Kalkrückständen aus Gefässen, Geräten und Rohrleitungen wird vielfach .mit Säuren durchgeführt. Entsprechende flüssige Produkte sind in vielfältiger Form im Handel. Wegen ihres flüssigen Zustandes ist deren Handhabung und Anwendung umständlich. Auch sind die Dosierempfehlungen dabei stets in allgemeiner summarischer Form gehalten, ohne Bezug auf die zu entferndende Kalkmenge. Dies führt entweder zu unnötig hohem Verbrauch an Entkalkungsmittel und überflüssiger Umweltbelastung oder zu unvollständiger Entkalkung.The removal of limescale residues from vessels, devices and pipelines is often carried out with acids. Corresponding liquid products are available in various forms. Because of their liquid state, they are easy to handle and application cumbersome. The dosage recommendations are always kept in a general summary form, without reference to the amount of lime to be removed. This either leads to an unnecessarily high consumption of decalcifying agent and unnecessary environmental pollution or incomplete decalcification.

Der Erfindung liegt die Aufgabe zugrunde, ein Entkalkungsmittel für den Haushalt in handlicher Form zu formulieren,The invention is based on the object of a decalcifying agent to be formulated in a handy form for the household,

das auch seine genaue Dosierung in Bezug auf die zu entfernende Kalkmenge erlaubt. Erfindungsgemäss wird dies durch ein Mittel in Tablettenform erreicht, welches als Kalklöser schwache Säuren, Komplexbildner oder Salze und einen Indikator enthält, der die Beendigung des Entkalkungsvorganges anzeigt.which also allows its exact dosage in relation to the amount of lime to be removed. According to the invention this is done by an agent in tablet form, which acts as a limescale remover, weak acids, complexing agents or salts and an indicator which indicates the end of the descaling process.

Bei Erschöpfung des Wirkstoffes schlägt die Farbe der Reinigungslösung um, z.B. im Falle bei Verv/endung von Tropaeolin 00 als Indikator, von rot nach gelb, d.h. es muss Wirkstoff nachdosiert werden. Sobald nun nach einiger Einwirkungszeit kein Farbumschlag mehr*auftritt, also z.B. im Falle von Tropaeolin 00 die rote Farbe bestehen bleibt, kann der Entkaikungsvorgang als beendet betrachtet werden.When the active ingredient is exhausted, the color of the cleaning solution beats in order, e.g. in the case of using Tropaeolin 00 as an indicator, from red to yellow, i.e. it must be active ingredient be replenished. As soon as now after some exposure time no more color change * occurs, e.g. in the case of tropaeolin 00 the red color remains, the decaling process can be considered finished.

Vorzugsweise wird ein Indikator verwendet, v/elcher bei einex-Wasserstoffionenkonzentration von pH 2 bis pH 4 umschlägt, wie z.B. Tropaeolin 00, Thymolblau, Dinitrophenol. Die Menge an Indikator beträgt 0,001 bis 0,01 Gew.-%, bezogen auf das Gewicht des Entkalkungsmittels.An indicator is preferably used which changes at a hydrogen ion concentration of pH 2 to pH 4, such as tropaeolin 00, thymol blue, dinitrophenol. The amount of indicator is 0.001 to 0.01% by weight , based on the weight of the descaling agent.

Als Kalklöser kommen in Betracht: schwache Säuren, wie Nikotinsäure, Komplexbildner, wie Citronensäure, Apfel- -säure, Amidosulfonsäuren ferner Natriumhydrogensulfat, Harnstoffnitrat oder deren Mischungen.The following decalcifying agents can be considered: weak acids such as nicotinic acid, complexing agents such as citric acid, malic acid, amidosulfonic acids and sodium hydrogen sulfate, Urea nitrate or mixtures thereof.

Erfindungsgemäss werden die Entkalkungsmittel in Tablettenform verwendet, wobei dann Nikotinsäure in Mengen von etwa 5 bis 50 % zugleich als Tablettierhilfe dienen und die Ober- According to the invention, the decalcifying agents are used in tablet form , in which case nicotinic acid in quantities of about 5 to 50 % also serves as a tablet aid and the upper

609809/0865609809/0865

fläche der Tabletten mit 0,1 bis 3 % Bitterstoffen vergällt sein kann.Ferner empfiehlt sich die Zugabe von Korrosionsinhibitoren in i^engen von ca. 0,1 bis 1 %. The surface of the tablets can be denatured with 0.1 to 3% bitter substances. In addition, it is advisable to add corrosion inhibitors in amounts of approx. 0.1 to 1 %.

Beispiel 1 Example 1

99,4 % Amidosulfonsäure (Kalklöser), 0,5 % Korrosionsinhibitor, O,1 % Bitterstoffe und 0,003 % Tropaeolin 00 werden miteinander gemischt und auf übliche Weise in einer Tablettenpresse zu Tabletten geformt.99.4 % amidosulphonic acid (lime remover), 0.5 % corrosion inhibitor, 0.1% bitter substances and 0.003 % Tropaeolin 00 are mixed with one another and shaped into tablets in the usual way in a tablet press.

Beispiel 2Example 2

Gleich wie Beispiel 1 mit dem Unterschiede, dass 80 % Amidosul'fonsäure und 19,4 % Nikotinsäure verwendet v/erden, letztere ist zwar ein schwächerer Kalklöser, dient aber zugleich als Tablettierhilfsmittel.Same as example 1 with the difference that 80 % amidosulphonic acid and 19.4 % nicotinic acid are used, the latter is indeed a weaker limescale remover, but at the same time serves as a tableting aid.

Werden Tabletten von z.b". 5 g hergestellt, so benötigt man zur Bestellung einer wirksamen Entkalkungslösung ca. 3 bis 4 Tabletten pro Liter Wasser.If tablets of e.g. ". 5 g are produced, you need approx. 3 to to order an effective decalcifying solution 4 tablets per liter of water.

Alle in der Patentschrift angegebenen Prozentzahlen sind Gewichtsprozente und beziehen sich auf das Gewicht des Entkalkungsmittels. All percentages given in the patent are percentages by weight and relate to the weight of the descaling agent.
