Description
Die Erfindung betrifft flüssige Sanitärreinigungs- und Entkalkungsmittel, die insbesondere für die Reinigung von WC's und anderen sanitären Anlagen verwendet werden können.The invention relates to liquid sanitary cleaning and decalcifying agents, which especially for cleaning toilets and others sanitary facilities can be used.
Die bekannten flüssigen Mittel für dieses Einsatzgebiet enthalten üblicherweise als Säurekomponente Mineralsäuren wie Salz-, Phosphor-, Schwefel- oder Sulfonsäure, aber auch Amidosulfonsäure und organische Säuren wie Ameisen-, Essig- oder Zitronensäure oder Mischungen dieser Säuren.The known liquid agents for this area of application contain usually as acid component mineral acids such as hydrochloric, phosphoric, Sulfuric or sulfonic acid, but also sulfamic acid and organic acids such as formic, acetic or citric acid or Mixtures of these acids.
Weiterhin beinhalten diese Mittel Detergentien, Farb- und Duftstoffe. Um das Ablaufen an senkrechten oder schrägen Oberflächen zu verlangsamen, damit eine längere Einwirkzeit erzielt wird, werden diese flüssigen Reinigungsmittel in der Regel verdickt. Da nun wie oben ausgeführt starke Säuren zum Einsatz kommen, muß jeweils geprüft werden, inwieweit die eingesetzten Verdickungsmittel sich mit den Säuren vertragen. Die typischen reinen Verdickungsmittel wie Guar-Mehl; Xanthen Gum oder Cellulose-Derivate weisen in diesen sauren Medien eine nicht ausreichende Lagerstabilität auf, so daß sie nach gewisser Lagerzeit solcher Mischungen ihre Verdicker-Eigenschaften verlieren. Die Lagerstabilität solcher Mischungen liegt zum Teil unter 1 Woche. In vielen solchen Mischungen wurden als Verdickungsmittel die nicht-ionischen Nonylphenoloxyethylate eingesetzt. Diese nicht-ionischen Tenside haben den Vorteil, daß sie neben der Verdickungswirkung zugleich eine Tensidwirkung aufweisen. Allerdings haben diese Tenside einen ganz gravierenden Nachteil: Sie sind äußerst schlecht abbaubar, sie zeigen ungünstige Eigenschaften im Abbauverhalten und müssen, um die gewünschte Verdickungswirkung zu zeigen, in hohen Konzentrationen eingesetzt werden (6-10 Gew.-%). Es ist daher unumgänglich umweltfreundlichere, nicht-ionische Verdickungsmittel zum Einsatz zu bringen, damit die angestrebten Viskositäten dieser Mittel im Bereich von 100-2000 mPa · s erreicht werden. Ein bedeutender Nachteil ist, daß fast immer mit Aluminiumchlorid, NaCl bzw. NH₄Cl zur Viskositätssteigerung gearbeitet werden muß. Bekannterweise sind Cl--Ionen gegenüber fast allen Materialien korrosiv, z. T. korrosiver als die miteingesetzten Säuren. Zum anderen ergibt der Einsatz dieser Salze eine zusätzliche Umweltbelastung, die nicht unbedingt wünschenswert ist. Ferner sind alle Stickstoffabkömmlinge aus ökologischer Sicht nicht unbedenklich. So beschreibt die DE-OS 35 42 970 ein Sanitärmittel, daß als Verdickungsmittel Alkylethersulfate, amphotere Tenside bzw. Mischungen aus nicht-ionischen Tensiden mit oxyethylierten Aminen enthalten. Weiter wird in dieser Schrift ausgeführt, daß beim Einsatz von nicht-ionischen Tensiden allein unerwünscht hohe Konzentrationen einzusetzen sind, damit eine ausreichende Verdickung erreicht wird.These agents also contain detergents, colors and fragrances. These liquid cleaning agents are usually thickened in order to slow down the drainage on vertical or inclined surfaces so that a longer exposure time is achieved. Since strong acids are used as stated above, it must be checked to what extent the thickeners used are compatible with the acids. The typical pure thickeners like guar flour; Xanthene gum or cellulose derivatives do not have sufficient storage stability in these acidic media, so that after a certain storage time of such mixtures they lose their thickening properties. The storage stability of such mixtures is sometimes less than 1 week. In many such mixtures, the nonionic nonylphenoloxyethylates have been used as thickeners. These non-ionic surfactants have the advantage that they also have a surfactant effect in addition to the thickening effect. However, these surfactants have a very serious disadvantage: they are extremely poorly degradable, they show unfavorable properties in terms of degradation behavior and, in order to show the desired thickening effect, they have to be used in high concentrations (6-10% by weight). It is therefore essential to use more environmentally friendly, non-ionic thickeners so that the desired viscosities of these agents can be achieved in the range of 100-2000 mPa · s. A significant disadvantage is that it is almost always necessary to work with aluminum chloride, NaCl or NH₄Cl to increase the viscosity. As is known, Cl - ions are corrosive to almost all materials, e.g. T. more corrosive than the acids used. On the other hand, the use of these salts results in additional environmental pollution, which is not absolutely desirable. Furthermore, all nitrogen derivatives are not harmless from an ecological point of view. For example, DE-OS 35 42 970 describes a sanitary agent which contains alkyl ether sulfates, amphoteric surfactants or mixtures of nonionic surfactants with oxyethylated amines as thickeners. This document also states that when using non-ionic surfactants alone, undesirably high concentrations are to be used so that sufficient thickening is achieved.
Auch die DE-OS 23 59 095 beschreibt nicht-ionische Tenside als Verdickungsmittel in Sanitärreinigern. Dort werden tertiäre Amine verwendet, die ebenfalls Nachteile hinsichtlich der Lagerstabilität aufweisen.DE-OS 23 59 095 also describes non-ionic surfactants as thickeners in sanitary cleaners. There tertiary amines are used, the also disadvantages in terms of storage stability exhibit.
Es bestand daher die Aufgabe, flüssige Sanitärreinigungs- und Entkalkungsmittel, die insbesondere zur Reinigung von WC's und anderen sanitären Anlagen verwendet werden können, zu entwickeln, die ein als Verdicker wirkendes nicht-ionisches Tensid enthalten, das günstige Umwelt- und Abbau-Eigenschaften besitzt.It was therefore the task of liquid sanitary cleaning and decalcifying agents, especially for cleaning toilets and others plumbing can be used to develop the one contain as a thickener acting non-ionic surfactant, the cheap Has environmental and degradation properties.
Diese Aufgabe wurde durch eine Mischung gelöst, die aus der üblichen Säurekomponente für Sanitärreiniger und einem Gemisch aus ethoxilierten Fettalkoholen mit 1-7 EO-Einheiten bzw. 8-14 EO-Einheiten bei einer Alkylkettenlänge von C₁₀-C₁₈, wobei das C₁₀-C₁₈- Fettalkoholethoxylat mit 1-7 EO-Einheiten einen freien Fettalkoholgehalt von unter 5% aufweisen muß, sowie üblichen Zusatzstoffen besteht.This problem was solved by a mixture of the usual Acid component for sanitary cleaners and a mixture of ethoxylated Fatty alcohols with 1-7 EO units or 8-14 EO units with an alkyl chain length of C₁₀-C₁₈, the C₁₀-C₁₈- Fatty alcohol ethoxylate with 1-7 EO units has a free fatty alcohol content must have less than 5%, as well as conventional additives.
Gegenstand der Erfindung ist daher ein verdicktes saures wäßriges Sanitär- und Reinigungsmittel bestehend aus 2-40 Gew.-% Säure, 2-10 Gew.-% C₁₀-C₁₈-Fettalkoholethoxylat mit 8-14 EO-Einheiten und 2-10 Gew.-% Verdickungsmittel, welches dadurch gekennzeichnet ist, daß als Verdickungsmittel ein Fettalkoholethoxylat mit 1-7 EO-Einheiten verwendet wird, wobei der freie Fettalkoholgehalt unter 5% beträgt.The invention therefore relates to a thickened acidic aqueous Sanitary and cleaning agents consisting of 2-40% by weight acid, 2-10 wt .-% C₁₀-C₁₈ fatty alcohol ethoxylate with 8-14 EO units and 2-10 wt .-% thickener, which is characterized is that a fatty alcohol ethoxylate with 1-7 EO units are used, with the free fatty alcohol content below Is 5%.
Es wurde überraschend gefunden, daß Fettalkoholethoxylate, die weniger als 5% freien Fettalkoholgehalt aufweisen, bei Einsatzkonzentrationen von insbesondere 3-7 Gew.-% in Sanitärreinigermischungen, die aus 2-40 Gew.-% Säure und 2-10 Gew.-% normalen Fettalkoholethoxylat bestehen, eine außergewöhnliche Verdickereinwirkung aufweisen.It has surprisingly been found that fatty alcohol ethoxylates are less than 5% free fatty alcohol content, at use concentrations of in particular 3-7% by weight in sanitary cleaner mixtures, that from 2-40 wt .-% acid and 2-10 wt .-% normal fatty alcohol ethoxylate exist, an unusual thickening action exhibit.

It can also be sulfamic acid be used. This acid can be used individually or in Mixture can be used according to the invention.
Die großtechnische Addition von Ethylenoxid (Oxyethylierung) an Fettalkoholen wird diskontinuierlich im Batchprozeß durchgeführt. Die Reaktion wird im Normalfall basisch katalysiert, wobei Natrium, Natriummethylat, Natrium- oder Kaliumhydroxid als Katalysatoren Verwendung finden. Die Reaktionstemperatur beträgt zwischen 140 und 200°C bei einem Druck von ca. 2 bar. Um eine erhöhte Polyglykolbildung zu vermeiden, muß in Abwesenheit von Wasser gearbeitet werden (Stache "Tensid-Taschenbuch", 2. Auflage 1981, Seite 155 ff.).The large-scale addition of ethylene oxide (oxyethylation) Fatty alcohols are carried out batchwise in the batch process. The reaction is normally catalyzed basic, with sodium, Sodium methylate, sodium or potassium hydroxide as catalysts Find use. The reaction temperature is between 140 and 200 ° C at a pressure of approx. 2 bar. To increase polyglycol formation to avoid, must be worked in the absence of water (Stache "Tensid-Taschenbuch", 2nd edition 1981, page 155 ff.).
Der freie Fettalkohol liegt in der Regel für 1-7 EO-Einheiten zwischen 30 und 10%.The free fatty alcohol is usually for 1-7 EO units between 30 and 10%.
Es gelangen als erfindungsgemäß zu verwendende Fettalkoholoxyethylate mit C₁₀-C₁₈-, insbesondere C12-15-, Alkylgruppen bei Ethoxylierungsgraden von 8-14, insbesondere 10-12, EO-Einheiten zum Einsatz. As fatty alcohol oxyethylates to be used according to the invention with C₁₀-C₁₈, in particular C 12-15 , alkyl groups at degrees of ethoxylation of 8-14, in particular 10-12, EO units are used.
Bei 200-220°C und einem Druck von <10 mbar wurden innerhalb 1 h ca. 20-30% abdestilliert. Der Rückstand ist das Verdickungsmittel und enthält weniger als 5% freien Fettalkohol. Die Bestimmung erfolgte durch eine HPLC-Analytik.At 200-220 ° C and a pressure of <10 mbar were within 1 h about 20-30% distilled off. The residue is the thickener and contains less than 5% free fatty alcohol. The determination was carried out by HPLC analysis.
