Abstract

Rinse consists of mixture of H3PO4, tensides and citric acid in aqueous soln.

Description

Spülmittel, insbesondere Klarspülmittel für Geschirr und dergl, Die Erfindung betrifft ein Spülmittel, insbesondere ein KlarspUlmittel für Geschirr und dergl., bestehend aus einem Gemisch von Phosphorsäure und Tensiden in wässriger Lösung. Detergents, in particular rinse aid for dishes and the like, The The invention relates to a detergent, in particular a rinse aid for dishes and the like. Consisting of a mixture of phosphoric acid and surfactants in aqueous Solution.

Nachdem das Geschirr in der Geschirrspülmaschine einer Reinigung unterworfen ist, schliesst sich ein Klarspülvorgang an, Hierbei wird dem Spülwasser ein Klarspülmittel zugesetzt, das die Aufgabe hat, etwaige Rückstände, insbesondere Ablagerungen aus dem Wasser, fortzuspülen und das gewaschene Gut mit einem gleichmässigen Glanzfilm zu überziehen, Bei Verwendung von Wasser mit üblichen Wasserhärten wird diese Wirkung mit den bisher handelsüblichen Mitteln in der Regel in ausreichendem Maße erzielt, Doch hat es sich gezeigt, dass bei besonders mineralhaltigen Wässern, wie sie z,B, auf der Schwäbischen Alb vorkommen, feine Ablagerungen auf dem Geschirr haften bleiben, die diesem ein fleckiges Aus sehen verleihen, Der Erfindung liegt die Aufgabe zugrunde, ein Klarspülmittel zu schaffen, das diese Nachteile beseitigt und selbst bei Verwendung von Wasser mit extrem hohen Härtegraden sowie mit hohen Anteilen von Mineralien das Geschirr rückstandslos klarspült, Diese Aufgabe wird dadurch gelöst, dass einem Spülmittel, bestehend aus einem Gemisch von Phosphorsäure und Tensiden in wässriger Lösung, Zitronensäure zugesetzt wird, Hierdurch werden die mineralhaltigen Anteile chemisch abgebaut, so dass keinerlei Ablagerungen auf dem gewaschenen Gut ersichtlich sind. Nachfolgend wird die Erfindung an Hand von Anwendungsbeispielen näher erläutert, Folgende Zusammensetzungen für das Klarspülmittel ergaben günstige Ergebnisse: I. 100 g Zitronensäure, die in Kristallform vorliegt, werden in 200 g Wasser, das eine Temperatur von ca, 900 aufweist, aufgelöst0 Hinzu kommen 600 g 85 Üge klare Phosphorsäure sowie 30 % Tenside üblicher Zusammensetzung in neutraler Einstellung.After the dishes have been subjected to cleaning in the dishwasher is followed by a rinsing process, where the rinse water becomes a rinse aid added, which has the task of removing any residues, especially deposits the water, to rinse away and the washed items with an even, glossy film to coat, When using water with normal water hardness this effect will be usually achieved to a sufficient extent with the means previously available in the trade, However, it has been shown that in the case of waters that are particularly rich in minerals, such as occur in the Swabian Alb, fine deposits stick to the dishes, which give this a blotchy look, The invention is based on the object to provide a rinse aid that eliminates these drawbacks and even when in use of water with extremely high degrees of hardness as well as with high proportions of minerals rinses the dishes without leaving any residue. This task is achieved in that a Washing-up liquid, consisting of a mixture of phosphoric acid and surfactants in water Solution, citric acid is added, this removes the mineral-containing parts chemically degraded, so that no deposits are visible on the washed items are. The invention is explained in more detail below with the aid of application examples. The following Compositions for the rinse aid gave favorable results: I. 100 g citric acid, which is in crystal form, are in 200 g of water, which has a temperature of approx. 900, dissolved0 In addition, there are 600 g 85 Üge clear phosphoric acid and 30 % Surfactants of usual composition in neutral setting.

II, 300 g Wasser, 600 g 60 ziege Phosphorsäure, 100 g Zitronensäure, ca, 30 % Tenside, III, 200 g Zitronensäure, 200 g Wasser, 600 g 85 %ige Phosphorsäure, Amidosulfonsäure in neutraler Einstellung als Tensid, Die Erfindung ist nicht auf diese Ausführungsbeispiele beschränkt, II, 300 g water, 600 g 60 goat phosphoric acid, 100 g citric acid, approx. 30% surfactants, III, 200 g citric acid, 200 g water, 600 g 85% phosphoric acid, Amidosulfonic acid in a neutral setting as a surfactant, the invention is not based limited these embodiments,
