Description

In Gegenden mit besonders hartem Wasser führt die Unterdosierung von Waschmitteln bei der Textilwäsche oder der Einsatz ungeeigneter Waschmittel bekanntlich zu Kalkablagerungen, sowohl auf Textilien als auch in den verwendeten Waschmaschinen. Die gewaschenen Textilien werden unter diesen Umständen nach kurzer Zeit grau bis fleckig und fühlen sich unangenehm hart an. Um diesen Nachteilen zu begegnen und die verhärteten Textilien wieder zu entkrusten (entkalken), behandelt man die Textilien nach der Wäsche in einem Nachspülgang, beispielsweise mit Harnstoffaddukten der Salpetersäure oder der Phosphorsäure, mit Amidosulfonsäure oder anderen Säuren. Hierdurch können jedoch recht starke Korrosionserscheinungen an Messing- oder Kupferteilen von Waschmaschinen auftreten.In areas with particularly hard water, the underdosing of detergents in textile washing or the use of unsuitable detergents is known to lead to limescale deposits, both on textiles and in the washing machines used. Under these circumstances, the washed textiles turn gray to stained after a short time and feel uncomfortably hard. In order to counteract these disadvantages and to descale the hardened textiles again, the textiles are treated in a rinse after washing, for example with urea adducts of nitric acid or phosphoric acid, with amidosulfonic acid or other acids. However, this can cause quite severe corrosion on brass or copper parts of washing machines.

In der deutschen Offenlegungsschrift 1 494 847 hat man bereits vorgeschlagen, pulverförmige lagerbeständige Entkalkungsmittel auf Basis eines Adduktes aus Harnstoff und Phosphorsäure dadurch zu verbessern, daß man ihnen 3 bis 60 Gew.-% Maleinsäureanhydrid zufügt. Hierdurch soll ein schnelleres und vollständigeres Auflösen der üblicherweise aus Kalk und Rost bestehenden Verkrustungen erfolgen. Diesen Mitteln konnten zur Verbesserung des Netzvermögens auch noch 0,1 bis 3 Gew.-% an kationischen, anionischen oder nichtionischen Tensiden zugesetzt werden. Auch die Beifügung von Korrosionsinhibitoren ist empfohlen worden, obgleich die Mittel selbst im Gegensatz zu bekannten sauren Entkalkungsmitteln eine nur sehr geringe Korrosionsneigung aufweisen und faserschonend wirken sollen. Nach einem Beispiel wurden 2% Kokosfettalkoholsulfat in einer Mischung aus 40 Gew.-% Phosphorsäure (100%ig) und 8 Gew.-% Wasser gelöst und hierzu 10 Gew.-% pulverförmiges Maleinsäureanhydrid hinzugefügt. Danach erfolgte die Zugabe von 27 Gew.-% Harnstoff. Nach dem Abkühlen und Erstarren des Gemisches wurden zur Verbesserung der Pulvereigenschaften noch 11 Gew.-% wasserfreies Natriumsulfat und 2 Gew.-% feinteilige Kieselsäure zugefügt.In German Offenlegungsschrift 1,494,847, it has already been proposed to improve pulverulent, storage-stable decalcifying agents based on an adduct of urea and phosphoric acid by adding 3 to 60% by weight of maleic anhydride. This is intended to dissolve the incrustations that usually consist of lime and rust more quickly and completely. To improve the wetting ability, 0.1 to 3% by weight of cationic, anionic or nonionic surfactants could also be added to these agents. The addition of corrosion inhibitors has also been recommended, although the agents themselves, in contrast to known acid decalcifying agents, have only a very low tendency to corrode and should have a gentle effect on the fibers. According to one example, 2% coconut fatty alcohol sulfate was dissolved in a mixture of 40% by weight phosphoric acid (100%) and 8% by weight water, and 10% by weight powdered maleic anhydride was added to it. This was followed by the addition of 27% by weight of urea. After the mixture had cooled and solidified, 11% by weight of anhydrous sodium sulfate and 2% by weight of finely divided silica were added to improve the powder properties.

Es hat sich gezeigt, daß die großtechnische Herstellung dieser wirkungsvollen Entkalkungsmittel zu aufwendig und damit zu kostenintensiv war und nur in nach modernsten Gesichtspunkten eingerichteten Fabrikationsstätten durchgeführt werden konnte, die aber in dem erforderlichen Umfang gar nicht vorhanden sind. Außerdem wurden von den Verbrauchern wegen der leichteren Dosierbarkeit flüssige Entkalkungsmittel verlangt.It has been shown that the large-scale production of these effective decalcifying agents was too complex and therefore too cost-intensive and could only be carried out in factories that were equipped according to the most modern criteria, but which are not available to the extent required. In addition, liquid descaling agents were required by consumers because of the easier metering.

Es lag daher nahe, den Unzuträglichkeiten des Standes der Technik dadurch zu begegnen, daß man die nach der deutschen Offenlegungsschrift 1494847 bekannten Bestandteile unter Weglassung der für flüssige Produkte nicht erforderlichen Adsorptionsmittel wie Natriumsulfat und feinteilige Kieselsäure in wäßriger Lösung herstellte und anbot. Dieser Versuch führte jedoch bei sonst unveränderter Konzentration der Bestandteile zu einer wäßrigen Lösung mit einem kristallinen Bodensatz. Eine Verringerung des Phosphorsäuregehaltes unter sonst gleichbleibenden Verhältnissen der übrigen Bestandteile auf 40 Gew.-% ergab zwar eine klare, jedoch in zwei Phasen getrennte Lösung, die bei weiterer Reduzierung des Phosphorsäuregehaltes auf 38 Gew.-% auch noch trübe wurde.It was therefore obvious to counteract the inconveniences of the prior art by producing and offering the components known from German Offenlegungsschrift 1494847 while omitting the adsorbents which are not required for liquid products, such as sodium sulfate and finely divided silica, in aqueous solution. However, this experiment led to an aqueous solution with a crystalline sediment, while the concentration of the constituents was otherwise unchanged. A reduction in the phosphoric acid content under otherwise unchanged ratios of the other constituents to 40% by weight resulted in a clear solution which was, however, separated into two phases and which also became cloudy when the phosphoric acid content was further reduced to 38% by weight.

Der Ersatz von Maleinsäureanhydrid durch reine Maleinsäure und des anionischen Tensids durch 2 bzw. 3 Gew.-% eines mit 10 Mol Ethylenoxid umgesetzten Nonylphenols ergab zunächst klare Lösungen, die auch bei Raumtemperatur nach 2 Tagen noch stabil waren, die jedoch innerhalb von 24 Stunden in der Wechselklimazelle (minus 10°C/plus 40 °C) fest und trübe wurden und sich nicht wieder verflüssigen ließen.Replacing maleic anhydride with pure maleic acid and the anionic surfactant with 2 or 3% by weight of a nonylphenol reacted with 10 moles of ethylene oxide initially gave clear solutions, which were still stable after 2 days even at room temperature, but which disappeared within 24 hours the alternating climate cell (minus 10 ° C / plus 40 ° C) became solid and cloudy and could not be liquefied again.

Es zeigte sich also, daß sich die Lehren des Standes der Technik, die sich auf ein homogenes pulverförmiges Produkt bezogen, nicht ohne weiteres auf die gewünschten Flüssigprodukte übertragen ließen. Die Lösung der Aufgabe erfolgte durch neuen Aufbau der Kompositionen.It was thus found that the teachings of the prior art, which related to a homogeneous powdery product, could not be readily applied to the desired liquid products. The task was solved by rebuilding the compositions.

Die vorliegende Erfindung betrifft somit ein Verfahren zur Herstellung eines homogenen, flüssigen Wäschebehandlungsmittels, das dadurch gekennzeichnet ist, daß man Maleinsäure in warmem Wasser löst, Phosphorsäure hinzufügt, in diese Lösung Harnstoff einrührt und anschließend unter weiterem Rühren nichtionische Tenside hinzufügt.The present invention thus relates to a process for producing a homogeneous, liquid laundry treatment agent, which is characterized in that maleic acid is dissolved in warm water, phosphoric acid is added, urea is stirred into this solution and then non-ionic surfactants are added with further stirring.

Die vorliegende Erfindung betrifft insbesondere ein Verfahren zur Herstellung eines klaren, homogenen, flüssigen Wäschebehandlungsmittels, das dadurch gekennzeichnet ist, daß man 5 bis 15, vorzugsweise 5 bis 10 Gew.-% Maleinsäure in 20 bis 50, vorzugsweise 25 bis 45 Gew.-% auf 40 bis 60°C erwärmtem Wasser löst, 20 bis 45, vorzugsweise 25 bis 38 Gew.-% Phosphorsäure (100%ig) hinzufügt, in diese Lösung 10 bis 25, vorzugsweise 15 bis 23 Gew.-% Harnstoff einrührt und anschließend 1 bis 10, vorzugsweise 1,5 bis 8 Gew.-% eines nichtionischen Tensids, vorzugsweise eines Gemisches mehrerer nichtionischer Tenside hinzufügt.The present invention relates in particular to a process for producing a clear, homogeneous, liquid laundry treatment agent, which is characterized in that 5 to 15, preferably 5 to 10% by weight of maleic acid in 20 to 50, preferably 25 to 45% by weight Dissolves water heated to 40 to 60 ° C, adds 20 to 45, preferably 25 to 38% by weight phosphoric acid (100%), stirs 10 to 25, preferably 15 to 23% by weight urea into this solution and then 1 to 10, preferably 1.5 to 8 wt .-% of a nonionic surfactant, preferably a mixture of several nonionic surfactants.

Man hätte annehmen können, daß man zur Herstellung flüssiger Mittel keinen Zusatz von Harnstoff brauchen würde, weil dieser nach dem Stand der Technik durch Adduktbildung zum Verfestigen der Phosphorsäure diente. Es hat sich aber gezeigt, daß Harnstoff wesentlich zur Homogenität der flüssigen Mittel beiträgt und in diesen gegenüber Messing und Kupfer eine Korrosionsinhibierung bewirkt.It could have been assumed that the addition of urea would not be necessary for the production of liquid agents, because according to the prior art this served to solidify the phosphoric acid by forming an adduct. However, it has been shown that urea contributes significantly to the homogeneity of the liquid agents and causes corrosion inhibition in them compared to brass and copper.

Gegebenenfalls kann man den erfindungsgemäßen Mitteln auch noch 0,5 bis 5, vorzugsweise 1,0 bis 4,5 Gew.-% eines weiteren, wasserfreien Korrosionsinhibitors, beispielsweise Alkylmonophosphonsäure mit 6 bis 10, vorzugsweise 8 bis 10 Kohlenstoffatomen im Molekül zusetzen.If appropriate, 0.5 to 5, preferably 1.0 to 4.5% by weight of a further, water-free corrosion inhibitor, for example alkyl monophosphonic acid having 6 to 10, preferably 8 to 10, carbon atoms in the molecule can also be added to the agents according to the invention.

Zur leichteren Einarbeitung dieser Korrosionsinhibitoren empfiehlt es sich, nach einem in der deutschen Offenlegungsschrift 2 841 641 vorgeschlagenen Verfahren vorzugehen und die Alkylmonophosphonsäuren zunächst mit einem Teil der nichtionischen Tenside zu mischen und dieses Gemisch dann im Anschluß an die Zugabe von Harnstoff in die Lösung einzuarbeiten. Anschließend kann dann unter Rühren die restliche Tensidmenge hinzugegeben werden.To facilitate the incorporation of these corrosion inhibitors, it is advisable to proceed according to a process proposed in German Offenlegungsschrift 2,841,641 and to mix the alkyl monophosphonic acids with part of the nonionic surfactants and this Then incorporate the mixture into the solution following the addition of urea. The remaining amount of surfactant can then be added with stirring.

Als nichtionische Tenside kommen sowohl Alkylphenole mit 8 bis 18, vorzugsweise 9 bis 15 Kohlenstoffatomen im Alkylrest als auch Alkanole bzw. Alkenole mit 12 bis 22, vorzugsweise 12 bis 18 Kohlenstoffatomen, die 2 bis 20, vorzugsweise 5 bis 10 Mol Ethylenoxid umgesetzt wurden, und deren Gemische in Betracht.Suitable nonionic surfactants are both alkylphenols with 8 to 18, preferably 9 to 15, carbon atoms in the alkyl radical and alkanols or alkenols with 12 to 22, preferably 12 to 18, carbon atoms which have reacted 2 to 20, preferably 5 to 10, moles of ethylene oxide, and their mixtures into consideration.

Es kann zweckmäßig sein, dem Mittel noch Lösungsmittel in Form von niedermolekularen aliphatischen Alkoholen, wie Methanol, Ethanol, lsopropanol oder Butanol und/oder gegebenenfalls auch Lösungsvermittler wie niedermolekulare Alkylbenzolsulfonate zuzusetzen. Deren Mengen können bei 0,5 bis 5 Gew.-% liegen.It may be expedient to add solvents in the form of low molecular weight aliphatic alcohols, such as methanol, ethanol, isopropanol or butanol and / or optionally also solubilizers such as low molecular weight alkylbenzenesulfonates. Their amounts can be 0.5 to 5% by weight.
