Die Erfindung betrifft die Verwendung von Kombinationen aus speziellen polymeren Verdickungsmitteln und Tensiden als Verdickersysteme für hoch wasserhaltige funktionelle Flüssigkeiten.The invention relates to the use of combinations of special polymeric thickeners and surfactants as thickener systems for highly water-containing functional liquids.
Unter funktionellen Flüssigkeiten werden im Rahmen der vorliegenden Erfindung Hydraulikflüssigkeiten, Metallbearbeitungsflüssigkeiten (Kühlschmiermittel) und Metallhärtungsmedien verstanden. Als "hoch wasserhaltig" werden im Rahmen der vorliegenden Erfindung solche funktionellen Flüssigkeiten bezeichnet, deren Wassergehalt entweder mehr als 90 Gew.-% beträgt, falls keine niedermolekularen Glykole mitverwendet werden, oder mehr als 70 Gew.-%, bevorzugt mehr als 80 Gew.-%, beträgt für den Fall, daß neben dem Wasser als Verdünnungsmittel größere Anteile an niedermolekularen Glykolen, wie Ethylenglykol, Diethylenglykol, Propylenglykol oder Dipropylenglykol eingesetzt werden.In the context of the present invention, functional fluids are understood to mean hydraulic fluids, metalworking fluids (cooling lubricants) and metal hardening media. In the context of the present invention, functional liquids are referred to as "highly water-containing", the water content of which is either more than 90% by weight, if no low-molecular glycols are used, or more than 70% by weight, preferably more than 80% by weight. -%, for the case that in addition to the water as a diluent, larger proportions of low molecular weight glycols, such as ethylene glycol, diethylene glycol, propylene glycol or dipropylene glycol, are used.
Seit etwa 25 Jahren ist man bemüht, die bislang als funktionelle Flüssigkeiten verwendeten brennbaren Mineralöle bzw. Mineralölprodukte durch nicht brennbare wäßrige Flüssigkeiten zu ersetzen. Diese Entwicklung hat inzwischen zu wäßrigen funktionellen Flüssigkeiten geführt, deren Wassergehalt bereits über 90 Gew.-% beträgt (sog. viscous high water-based fluids). Für die Herstellung dieser hoch wasserhaltigen funktionellen Flüssigkeiten wurden als Verdickungsmittel vor allem wasserlösliche polymere Polyether(poly)ole bzw. Kombinationen dieser polymeren Polyether(poly)ole mit weiteren Hilfsmitteln vorgeschlagen. So sind z.B. in der US-A-4 481 367, in der EP-A-0 031 777 und der JA-A-41 300/81 polymere wasserlösliche Urethangruppen aufweisende Polyetherpolyole und in der DE-A-3 302 465 und der US-A-4 288 639 mit langkettigen 1,2-Epoxyalkanen modifizierte Polyethermonoalkohole für den genannten Zweck beschrieben. Aus den US―A―4 310 436 und 4 395 351 sind Kombinationen dieser modifizierten Polyethermonoalkohole mit sauren Phosphorsäureestern nichtionischer Polyethermonoalkohol-Emulgatoren bekannt und in der CA-A-1 163 041 werden Kombinationen dieser modifizierten Polyethermonoalkohole mit speziellen Polyetherestern, sauren Phosphorsäureestern nichtionischer Polyethermonoalkohol-Emulgatoren und speziellen geschwefelten Metallverbindungen beschrieben.For about 25 years, efforts have been made to replace the flammable mineral oils or mineral oil products previously used as functional liquids with non-flammable aqueous liquids. This development has meanwhile led to aqueous functional liquids, the water content of which is already over 90% by weight (so-called viscous high water-based fluids). In particular, water-soluble polymeric polyether (poly) oles or combinations of these polymeric polyether (poly) ole with other auxiliaries have been proposed as thickeners for the production of these highly water-containing functional liquids. For example, in US-A-4 481 367, in EP-A-0 031 777 and JA-A-41 300/81 polymeric water-soluble urethane groups containing polyether polyols and in DE-A-3 302 465 and US-A- 4,288,639 with long-chain 1,2-epoxyalkanes modified polyether monoalcohols for the stated purpose. Combinations of these modified polyether monoalcohols with acidic phosphoric acid esters of nonionic polyethermonoalcohol emulsifiers are known from US Pat. Nos. 4,310,436 and 4,395,351 and combinations of these modified polyethermonoalcohols with special polyetheresters, acidic phosphoric acid esters of nonionic polyethermonoalcohol are Emulsifiers and special sulfurized metal compounds are described.
Mit langkettigen 1,2-Epoxyalkanen modifizierte polymere wasserlösliche Polyetherpolyole und deren Verwendung als Verdickungsmittel für hoch wasserhaltige funktionelle Flüssigkeiten sind in der EP-A-61 822, der WO-A1-84/00361 und in den US―A―4 354 956 und 4 411 819 beschrieben. Kombinationen dieser modifizierten wasserlöslichen polymeren Polyetherpolyole mit weiteren Hilfsmitteln sind aus zahlreichen Patentschriften bekannt. So sind z.B. Kombinationen dieser modifizierten Polyetherpolyole mit sauren Phosphorsäureestern nichtionischer Polyethermonoalkohol-Emulgatoren in der EP―B―63 854, mit ethoxylierten Sorbit-monostearaten in der EP-B-61 823, mit Neocarbonsäuren in der US-A-4 390 439 oder längerkettigen Fettsäuren in der US-A-4 390 440, mit nichtionischen Tensiden bestimmter Strukturklassen in der EP-A-122 528, mit speziellen Aminen und sauren Phosphorsäureestern nichtionischer Polyethermonoalkohol-Emulgatoren in der US―A―4 312 775, mit speziellen Polyetherestern, definierten geschwefelten Metallverbindungen und Korrosionsinhibitoren in der US―A―4312 768 und mit Schmierfähigkeitsmodifikatoren, Dispergiermitteln und bestimmten Hochdruckadditiven in der US―A―4481 125 beschrieben.Polymeric water-soluble polyether polyols modified with long-chain 1,2-epoxyalkanes and their use as thickeners for highly water-containing functional liquids are described in EP-A-61 822, WO-A1-84 / 00361 and in US Pat. No. 4,354,956 and 4,411,819. Combinations of these modified water-soluble polymeric polyether polyols with other auxiliaries are known from numerous patents. For example, Combinations of these modified polyether polyols with acidic phosphoric acid esters of nonionic polyether monoalcohol emulsifiers in EP ― B ― 63 854, with ethoxylated sorbitol monostearates in EP-B-61 823, with neocarboxylic acids in US Pat.

Diese bekannten, als Verdickungsmittel bzw. Verdickersysteme für hoch wasserhaltige funktionelle Flüssigkeiten verwendeten polymeren wasserlöslichen Polyetherpolyole und deren Kombinationen mit weiteren Hilfsstoffen haben jedoch den Nachteil, daß die mit ihnen verdickten funktionellen Flussigkeiten nicht scherstabil sind, sondern daß sich deren Viskosität bei der Einwirkung von Scherkräften (z.B. Druck) verändert. Scherstabilität ist jedoch eine der wichtigsten Eigenschaften der funktionellen Flüssigkeiten. Insbesondere bei Hydraulikflüssigkeiten ist eine von Scherkräften unabhängige Viskosität unbedingt erforderlich.These known polymeric water-soluble polyether polyols used as thickeners or thickener systems for highly water-containing functional liquids and their combinations with other auxiliaries have the disadvantage, however, that the functional liquids thickened with them are not shear-stable, but that their viscosity changes when exposed to shear forces ( e.g. pressure) changed. However, shear stability is one of the most important properties of functional liquids. With hydraulic fluids in particular, a viscosity that is independent of shear forces is absolutely necessary.
Überraschenderweise wurde nun gefunden, daß man hervorragend scherstabile, hoch wasserhaltige funktionelle Flüssigkeiten erhält, wenn man als Verdickersystem Kombinationen aus wasserlöslichen polymeren Polyetherpolyolen, in denen mindestens 50% der Hydroxyl-Endgruppen durch Umsetzung mit einem einen C12―C30-Alkyl- oder C12―C30-Alkylenrest aufweisenden Monoisocyanat verkappt sind, und anionische und/oder nichtionische Tenside verwendet.Surprisingly, it has now been found that excellent shear-stable, highly water-containing functional liquids are obtained if, as a thickener system, combinations of water-soluble polymeric polyether polyols in which at least 50% of the hydroxyl end groups are reacted with a C 12 -C 30 -alkyl or C Monoisocyanate having 12 ―C 30 alkylene radical are blocked, and anionic and / or nonionic surfactants are used.
Die Erfindung betrifft daher die Verwendung von Kombinationen aus wasserlöslichen polymeren Polyetherpolyolen, in denen mindestens 50% der Hydroxyl-Endgruppen durch Umsetzung mit einem einen C12-C30-Alkyl- oder C12―C30-Alkylenrest aufweisenden Monoisocyanat verkappt sind, und anionischen und/oder nichtionischen Tensiden als Verdicker-Systeme für hoch wasserhaltige funktionelle Flussigkeiten.The invention therefore relates to the use of combinations of water-soluble polymeric polyether polyols in which at least 50% of the hydroxyl end groups are blocked by reaction with a monoisocyanate having a C 12 -C 30 -alkyl or C 12 -C 30 -alkylene radical, and anionic and / or nonionic surfactants as thickener systems for highly water-containing functional liquids.
Die Erfindung betrifft ferner hoch wasserhaltige funktionelle Flüssigkeiten, enthaltend außer Wasser Kombinationen aus wasserlöslichen polymeren Polyetherpolyolen, in denen mindestens 50% der Hydroxyl-Endgruppen durch Umsetzung mit einem einen C12-C31-Alkyl- oder C12―C30-Alkylenrest aufweisenden Monoisocyanat verkappt sind, und anionischen und/oder nichtionischen Tensiden und gegebenenfalls Schmierfähigkeitsverbesserer, Metalldesaktivatoren, Korrosionsinhibitoren, Entschäumer, Stoffe zum Einstellen oder Abpuffern von bestimmten pH-Werten, Alterungsschutzmittel, Biozide, Kennfarbstoffe und/oder Glykole.The invention further relates to highly water-containing functional liquids containing, in addition to water, combinations of water-soluble polymeric polyether polyols in which at least 50% of the hydroxyl end groups by reaction with a monoisocyanate having a C 12 -C 31 alkyl or C 12 -C 30 alkylene radical are capped, and anionic and / or nonionic surfactants and optionally lubricity improvers, metal deactivators, corrosion inhibitors, defoamers, substances for adjusting or buffering certain pH values, anti-aging agents, biocides, colorants and / or glycols.
Mit Hilfe der erfindungsgemäß zu verwendenden Kombinationen werden hoch wasserhaltige funktionelle Flüssigkeiten erhalten, die sich nicht nur insgesamt durch eine ausgezeichnete Beständigkeit, sondern auch durch eine hervorragende Scherstabilität auszeichnen.

Die in den erfindungsgemäß zu verwendenden Kombinationen einzusetzenden Monoisocyanat-verkappten wasserlöslichen polymeren Polyetherpolyole sind Umsetzungsprodukte von an sich bekannten polymeren wasserlöslichen Polyetherpolyolen, die eine mittlere Molmasse von 5.000 bis 70.000 (ermittelt durch Bestimmung der OH-Endgruppen; aus der Zahl der OH-Endgruppen wird die mittlere Molmasse nach folgender Formel berechnet:
Als C12-C30-Alkylreste kommen vor allem der Dodecyl-, Hexadecyl-, Octadecyl- und der Behenyl-Rest, als C12―C30-Alkylenrest vor allem der Oleylrest in Betracht. Diese aliphatischen Kohlenwasserstoffreste müssen nicht unbedingt unmittelbar an die Isocyanatgruppe gebunden sein, sondern können auch über andere Gruppen, z.B. aromatische Ringe und/oder Urethangruppen an die Isocyanatgruppe gebunden sein. Solche Monoisocyanate, in denen die langkettigen aliphatischen Kohlenwasserstoffreste nicht unmittelbar an die Isocyanatgruppe gebunden sind, sind beispielsweise die Additionsprodukte aus 1 Mol eines C12―C30-n-Alkanols, z.B. Lauryl-, Myristyl-, Cetyl-, Stearyl- oder Behenylalkohols oder des Oleylalkohols an 1 Mol eines aliphatischen, cycloaliphatischen, aromatischen oder heterocyclischen Diisocyanates.The C 12 -C 30 alkyl radicals are, in particular, the dodecyl, hexadecyl, octadecyl and the behenyl radical, and the C 12 -C 30 alkylene radical in particular the oleyl radical. These aliphatic hydrocarbon radicals do not necessarily have to be bonded directly to the isocyanate group, but can also be bonded to the isocyanate group via other groups, for example aromatic rings and / or urethane groups. Such monoisocyanates in which the long-chain aliphatic hydrocarbon radicals are not directly bound to the isocyanate group are, for example, the addition products from 1 mol of a C 12 -C 30 -n-alkanol, for example lauryl, myristyl, cetyl, stearyl or behenyl alcohol or of oleyl alcohol to 1 mole of an aliphatic, cycloaliphatic, aromatic or heterocyclic diisocyanate.
Für die Herstellung der mit den Monoisocyanaten verkappten wasserlöslichen polymeren Polyetherpolyole wird die Menge an Monoisocyanat so bemessen, daß mindestens 50%, vorzugsweise 70 bis 100%, besonders bevorzugt 85 bis 100% der im Wasser löslichen polymeren Polyetherpolyole vorliegenden Hydroxyl-Endgruppen verkappt sind.For the preparation of the water-soluble polymeric polyether polyols capped with the monoisocyanates, the amount of monoisocyanate is such that at least 50%, preferably 70 to 100%, particularly preferably 85 to 100% of the hydroxyl end groups present in the water-soluble polymeric polyether polyols are capped.
Die Verkappung der OH-Endgruppen der polymeren wasserlöslichen Polyetherpolyole mit den einen C12-C30-Alkyl- oder C12―C30-Alkylenrest aufweisenden Monoisocyanaten ist eine im Prinzip bekannte Reaktion (siehe z.B. Ullmann's Enzyklopädie der techn. Chemie, 4. Aufl., Band 19, Seiten 309-310). Das Ende der Umsetzung läßt sich IR-spektroskopisch an Hand des Verschwindens der für Isocyanate typischen Absorptionsbande bei etwa 2.270 cm-1. bestimmen. Diese Additionsreaktion läßt sich in bekannter Weise durch die Mitverwendung bekannter Katalysatoren beschleunigen.The capping of the OH end groups of the polymeric water-soluble polyether polyols with the monoisocyanates having a C 12 -C 30 alkyl or C 12 ―C 30 alkylene radical is a reaction which is known in principle (see, for example, Ullmann's Enzyklopadie der techn. Chemie, 4th ed ., Volume 19, pages 309-310). The end of the reaction can be determined by IR spectroscopy on the basis of the disappearance of the absorption band typical of isocyanates at about 2,270 cm -1 . determine. This addition reaction can be accelerated in a known manner by using known catalysts.
Die den verkappten wasserlöslichen Polyetherpolyolen zugrunde liegenden wasserlöslichen polymeren, gegebenenfalls Urethan- oder Estergruppen aufweisenden Polyetherpolyole der mittleren Molmasse 5.000 bis 70.000 sind bekannt oder nach an sich bekannten Verfahren erhältlich, z.B. durch Polymerisation von Ethylenoxid oder Copolymerisation von Ethylenoxid mit anderen Alkylenoxiden in Gegenwart von Verbindungen, die mindestens zwei aktive Wasserstoffatome aufweisen, und gegebenenfalls Modifizierung der so erhaltenen wasserlöslichen polymeren Polyetherpolyole durch Umsetzung mit Diisocyanaten oder Dicarbonsäuren zu wasserlöslichen, Urethan- bzw. Estergruppen aufweisenden polymeren Polyetherpolyolen oder durch Polymerisation von Ethylenoxid oder Copolymerisation von Ethylenoxid und anderen Alkylenoxiden in Gegenwart von Verbindungen, die zwei aktive Wasserstoffatome aufweisen und Umsetzung der erhaltenen wasserlöslichen Polyetherdiole mit Polyisocyanaten, unter Einhaltung eines Verhältnisses von Isocyanat-Gruppen/OH-Gruppen von höchstens 0,5:1, zu wasserlöslichen polymeren Urethangruppen aufweisenden Polyetherpolyolen.The water-soluble polymeric, optionally urethane or ester group-containing polyether polyols of average molecular weight 5,000 to 70,000 on which the blocked water-soluble polyether polyols are based are known or can be obtained by processes known per se, for example by polymerizing ethylene oxide or copolymerizing ethylene oxide with other alkylene oxides in the presence of compounds, which have at least two active hydrogen atoms, and optionally modifying the water-soluble polymeric polyether polyols thus obtained by reaction with diisocyanates or dicarboxylic acids to give water-soluble urethane or ester groups polymeric polyether polyols or by polymerizing ethylene oxide or copolymerizing ethylene oxide and other alkylene oxides in the presence of compounds which have two active hydrogen atoms and reacting the water-soluble polyether diols obtained with polyisocyanates, while maintaining a ratio of isocyanate groups / OH groups of at most 0.5 : 1, to water-soluble polymeric polyether polyols containing urethane groups.
Die erfindungsgemäß zu verwendenden Kombinationen aus speziellen Monoisocyanat-verkappten wasserlöslichen polymeren Polyetherpolyolen und anionischen und/oder nichtionischen Tensiden werden hergestellt, indem man beide Komponenten in flüssigem Zustand miteinander zu einer homogenen Flüssigkeit vermischt. Da sie bei Raumtemperatur vielfach fest sind, werden die Komponenten im allgemeinen auf Schmelztemperatur, das sind Temperaturen von 60 bis 100°C, erwärmt und bei dieser Temperatur so lange verrührt, bis eine homogene Flüssigkeit entstanden ist. Bei der Verwendung von Tensid-Gemischen kann es vorteilhaft sein, zunächst nur ein Tensid mit dem verkappten Polyetherpolyol in flüssigem Zustand zu vermischen und anschließend in die homogene Schmelze das zweite bzw. die restlichen Tenside einzurühren.The combinations of special monoisocyanate-capped water-soluble polymeric polyether polyols and anionic and / or nonionic surfactants to be used according to the invention are produced by mixing both components together in a liquid state to form a homogeneous liquid. Since they are often solid at room temperature, the components are generally heated to the melting temperature, ie temperatures from 60 to 100 ° C., and stirred at this temperature until a homogeneous liquid has formed. When using surfactant mixtures, it may be advantageous to first mix only one surfactant with the masked polyether polyol in the liquid state and then to stir the second or the remaining surfactants into the homogeneous melt.
Die so erhaltenen Kombinationen aus speziellen verkappten wasserlöslichen polymeren Polyetherpolyolen und anionischen und/oder nichtionischen Tensiden werden zur besseren Handhabbarkeit bei der Herstellung der funktionellen Flüssigkeiten durch Zugabe von Wasser zu flüssigen Konzentraten verdünnt, deren Wassergehalt etwa 30 bis 70 Gew.-%, vorzugsweise 40 bis 60 Gew.-% beträgt, bezogen auf das Gewicht des Konzentrates.The combinations of special capped water-soluble polymeric polyether polyols and anionic and / or nonionic surfactants obtained in this way are diluted by adding water to liquid concentrates, the water content of which is about 30 to 70% by weight, preferably 40 to, for better manageability in the preparation of the functional liquids 60% by weight, based on the weight of the concentrate.
Aus diesen Konzentraten werden durch weiteres Verdünnen mit Wasser die gebrauchsfertigen Hydraulikfluide, Metallbearbeitungsflüssigkeiten (Kühlschmiermittel) und Metallhärtungsmedien hergestellt.The ready-to-use hydraulic fluids, metalworking fluids (cooling lubricants) and metal hardening media are produced from these concentrates by further dilution with water.
Die Konzentrate, bzw. die aus ihnen durch Verdünnen hergestellten funktionellen Flüssigkeiten können zusätzlich zum Wasser und dem Verdicker-System noch in diesen funktionellen Flüssigkeiten üblicherweise verwendete Zusätze enthalten. Das sind Schmierfähigkeitsverbesserer, Metalldesaktivatoren, Korrosionsinhibitoren, Entschäumer, Stoffe zum Einstellen oder Abpuffern bestimmter pH-Werte, Alterungsschutzmittel, Biozide, Kennfarbstoffe in den für diese Zusätze üblichen Mengen, sowie monomere und/oder oligomere Glykole enthalten.In addition to the water and the thickener system, the concentrates, or the functional liquids prepared from them by dilution, can also contain additives which are usually used in these functional liquids. These are lubricity improvers, metal deactivators, corrosion inhibitors, defoamers, substances for adjusting or buffering certain pH values, anti-aging agents, biocides, identification dyes in the usual amounts for these additives, as well as monomeric and / or oligomeric glycols.
Die erfindungsgemäß verdickten, hoch wasserhaltigen funktionellen Flüssigkeiten enthalten vorzugsweise außer Wasser und gegebenenfalls monomeren und/oder oligomeren Glykolen 3 bis 7 Gew.-% der erfindungsgemäß als Verdickersystem zu verwendende Kombination und gegebenenfalls zusätzlich 0,5 bis 3, vorzugsweise 1 bis 3 Gew.-%, der vorstehend genannten in funktionellen Flüssigkeiten üblicherweise verwendeten Zusätze, sowie gegebenenfalls bis zu 25 Gew.-%, z.B. 0,5 bis 20 Gew.-% monomere und/oder oligomere Glykole.In addition to water and optionally monomeric and / or oligomeric glycols, the highly water-containing functional liquids which are thickened according to the invention preferably contain 3 to 7% by weight of the combination to be used according to the invention as a thickener system and optionally additionally 0.5 to 3, preferably 1 to 3% by weight % of the above-mentioned additives commonly used in functional liquids, and optionally up to 25% by weight, for example 0.5 to 20% by weight of monomeric and / or oligomeric glycols.

Herstellung der erfindungsgemäß als Verdickersystem zu verwendenden Kombinationen aus Monoisocyanat verkapptem wasserlöslichem polymerem Polyetherpolyol und Tensid:Preparation of the combinations of monoisocyanate-capped water-soluble polymeric polyether polyol and surfactant to be used according to the invention as a thickener system:
Die in der nachstehenden Tabelle angegebenen Gew.-Teile an verkapptem Polyetherpolyol und Tensid werden durch Erwärmen auf etwa 90°C verflüssigt und zu einer homogenen Flüssigkeit verrührt. Diese wird anschließend durch Zugabe von Wasser auf ein 50 Gew.-% Wasser enthaltendes Konzentrat verdünnt.The parts by weight of capped polyether polyol and surfactant given in the table below are liquefied by heating to about 90 ° C. and stirred into a homogeneous liquid. This is then diluted by adding water to a concentrate containing 50% by weight of water.
In diesem Fall wird die in der Tabelle angegebenen Menge an verkapptem Polyetherpolyol zunächst nur mit einem der zu verwendenden Tenside in der für dieses Tensid in der Tabelle angegebenen Menge durch Erwärmen auf etwa 90°C verflüssigt und zu einer homogenen Flüssigkeit verrührt. In diese wird anschießend ebenfalls noch bei erhöhter Temperatur das andere bzw. die anderen Tenside in der für dieses bzw. diese Tenside in der Tabelle angegebenen Menge eingerührt, bis ebenfalls wieder eine homogene Flüssigkeit entstanden ist. Auch diese wird wieder durch Zugabe von Wasser auf ein 50 Gew.-% Wasser enthaltendes Konzentrat verdünnt.In this case, the amount of capped polyether polyol given in the table is first liquefied with only one of the surfactants to be used in the amount given for this surfactant in the table by heating to about 90 ° C. and stirred into a homogeneous liquid. The other or the other surfactants in the amount specified for this or these surfactants in the table are then also stirred into this at an elevated temperature until a homogeneous liquid has also formed again. This is again diluted by adding water to a concentrate containing 50% by weight of water.
Die nach a) oder b) erhaltenen Konzentrate werden unter Rühren durch Zugabe von weiterem Wasser auf 100 Gewichtsteile Lösung verdünnt. In einem besonders gekennzeichneten Fall wird mit einem Gemisch aus 80 Gew.-% Wasser, 10 Gew.-% Diethylenglykol und 10 Gew.-% Dipropylenglykol auf 100 Gewichtsteile Lösung verdünnt. Von den so erhaltenen verdickten wäßrigen Lösungen (funktionellen Flüssigkeiten), deren Wassergehalt in Abhängigkeit von der verwendeten Menge an Verdicker-System 91 bis 95,5 Gew.-% beträgt, werden die Viskositäten bei 40 und 50°C und die Änderung der Viskosität bei Einwirkung von Scherkräften (gemäß DIN 51 382; Abänderung: 300 Cyclen anstelle von 30 Cyclen) bestimmt. Die erhaltenen Werte und das aus den Viskositäten bei 40 und 50°C errechnete Viskositätsverhältnis sind in der nachfolgenden Tabelle zusammengestellt. Außerdem ist in der Tabelle in der Spalte "Verdickungsfaktor durch Tensid-Zusatz" der Faktor angegeben, um den die Viskosität des erfindungsgemäß verdickten Wassers höher ist als die Viskosität des nur mit dem verkappten Polyetherpolyol verdickten Wassers (aus diesem Verdickungsfaktor geht die synergistische Wirkung des Tensids in den erfindungsgemäßen Kombinationen hervor).
