Definitions
- Additive includes.
- the invention relates to a mixture comprising two components I and II, an emulsion which are prepared from the mixture and may also be present as a microemulsion, in particular a bicontinuous microemulsion, and a cleaner, a cosmetic article and a foodstuff which comprise the emulsion and a use of the cleaner.
- Surfactants are detergent substances (detergents) that are contained in detergents, dishwashing detergents, and shampoos. They have a characteristic structure and have at least one hydrophilic and one hydrophobic structural unit. They have an amphiphilic character. If the stabilizing character of water-oil mixtures is in the foreground, these amphiphilic substances are used as emulsifiers. Surfactants lower the interfacial tension between immiscible phases, a hydrophilic (water-soluble, lipophobic), mostly aqueous phase, and a hydrophobic (oil-soluble, lipophilic) phase. Such liquid two-phase mixtures are referred to as emulsions. Conventional emulsions may contain hydrophilic and hydrophobic phases in different volumes.
- microemulsions are thermodynamically stable, emulsions disintegrate due to their instability. At the microscopic level, this difference is reflected in the fact that the emulsified liquids in microemulsions are enclosed in smaller volumes of liquid (eg 10 "15 ⁇ l_) as described in emulsions (eg 10 "12 ⁇ l_) as described in DE 10 2005 049 765 A. Thermodynamically unstable emulsions thus have larger structures.
- Lamellar mesophases can occur in microemulsions. Lamellar mesophases lead to optical anisotropy and increased viscosity. These properties are for. B. undesirable for cleaners. In addition, phase separation often occurs when lamellar phases coexist with microemulsions.
- Microemulsions consist of at least three components, namely oil, water and a surfactant [1-7]. Oil and water are immiscible and therefore form domains on the nanoscale. The surfactant mediates between these two components and allows a macroscopic-homogeneous mixture. On a microscopic scale, the surfactant forms a film between the oil and water domains. Microemulsions are macroscopically homogeneous, behave optically isotropically and are thermodynamically stable in contrast to emulsions. There are W / O and O / W droplet microemulsions in which water droplets from the oil or oil droplets are enclosed by the water. Approximately equal proportions of oil to water promote the formation of a bicontinuous microemulsion.
- Characteristic of the efficiency of a surfactant is the minimum amount of surfactant required to stabilize emulsions over the desired period or to obtain a microemulsion.
- Microemulsions have been extensively studied in the field of basic science [8, 9]. The knowledge gained is largely based on the use of pure, defined components: deionized water, chemically pure oils and pure surfactants. In technical microemulsions, the components usually consist of mixtures. As a result, the phase ratio changes considerably and the findings from basic research gained in simplified models can not be without further be transferred to technical applications. Another difficulty lies in the low temperature stability of microemulsions, since in practical formulations stability must be present over a wide temperature range. Particularly systems based on fatty alcohol ethoxylates frequently used are stable only in a very narrow temperature window of a few 0 C and extremely high levels of surfactant must be used.
- microemulsions made with the aid of sugar surfactants can be stable over larger temperature ranges.
- mixtures of nonionic and ionic surfactants can be used.
- sugar surfactants and nonionic surfactant mixtures also have disadvantages.
- Microemulsions of sugar surfactants can only be produced with the help of cosurfactants.
- monohydric alcohols such as hexanol or octanol are used.
- Microemulsions containing ionic surfactants are sensitive to changes in salt concentration.
- Hazardous material potential They are particularly irritating to the skin and eyes.
- alkyl polyglucosides which are produced from renewable raw materials and have only a moderate hazardous substance potential and are also relatively skin-friendly.
- Sorbitan esters which have a very low hazard potential and are also largely produced from renewable raw materials, have been little explored in terms of their use in microemulsions so far.
- DE-A-198 39 054 discloses a process for increasing the efficiency of surfactants with simultaneous suppression of lamellar mesophases, a process for stabilizing the temperature position of the single phase region for oil, water surfactant mixtures, a process for increasing the structure size of emulsified liquid particles in microemulsions and a A method for reducing the interfacial tension of oil-water mixtures to which AB block copolymers having a water-soluble block A and a water-insoluble block B are added.
- the polymers consist of a water-soluble block A and a hydrophobic block.
- the lower limits of the number average molecular weights for A and B are 500 g / mol. This method is suitable for the production of microemulsions.
- DE-A-103 23 180 describes mixtures containing a surfactant and a cosurfactant which are characterized in that the cosurfactant used is an amphiphilic comb polymer comprising a backbone with two or more side chains attached to the backbone, the side chains being mutually interlinked and / or distinguish the side chains from the backbone in their amphiphilic character.
- the cosurfactant is suitable for increasing the efficiency in microemulsions.
- DE-A-4417476 discloses a microemulsion containing alkyl glycosides and fatty acid polyol partial esters.
- the microemulsion should be present in a wide range of existence; however, a temperature range in which the microemulsion is stable is not disclosed.
- DE-A-198 24 236 proposes a method for cleaning printing presses or printing plates, in which the contaminants are removed from the surfaces to be cleaned by washing with a microemulsion which Water, a surfactant and a water-immiscible organic solvent.
- US-A-5719113 discloses detergents comprising an antibacterial substance, a nonionic surfactant and an amphoteric surfactant. In contrast to the mixture according to the invention, no second alcohol group-containing surfactant is disclosed.
- a technical problem underlying the invention is to provide a mixture which has improved properties and can be processed to form an emulsion, in particular a microemulsion.
- the emulsion according to the invention in particular microemulsion, has the advantage that it is free or virtually free of volatile organic compounds (so-called volatile organic compounds, VOC).
- VOC volatile organic compounds
- ⁇ 2, no. 11 is a volatile organic compound which has a vapor pressure of 0.01 kPa or more at 293.15 Kelvin.
- VOCs include e.g. Compounds of the substance groups alkanes / alkenes, aromatics, terpenes, halogenated hydrocarbons, esters, aldehydes and ketones.
- the mixture according to the invention comprises a component I comprising 80-20% by weight of a first surface-active component Ii which is an alkyl polyglucoside comprising 1-2 glucoside units and a hydrocarbon radical, in particular an alkyl radical of 6-16 C atoms, 20-80 %
- a component I 2 containing a second surfactant containing alcohol groups excluding an alkyl polyglucoside wherein the parts by weight relate only to the component I, and polymeric additive as component II
- the polymeric additive comprises as component Hi at least one water-soluble unit and at least one hydrophobic unit, wherein the ratio of the number average molecular weights of all water-soluble units and the number average molecular weights of all hydrophobic units is 2: 1 to 1000: 1 or 3: 1 to 1000: 1, in particular 5: 1 to 200: 1 and in particular 10: 1 to 50: 1 and wherein each at least one hydrophobic unit is a number average Molecular weight of at most 1000 g / mol, or the polymeric
- the polymeric additive of the components Hi, H 2 or H 3 may also be present in combination in the mixture.
- This component II which is included as a polymeric additive in the mixture according to claim 1, seems to lead to an increase in the efficiency of the surfactants in component I.
- surfactant saving is also advantageous for environmental or health reasons.
- Surfactants are ecologically particularly relevant substances whose environmental compatibility must be ensured.
- Another advantage of surfactant savings occurs when surfactants interfere with the application of the microemulsion.
- cosmetics may be mentioned whose surfactant content should be as low as possible due to the skin-influencing effect possibly occurring in the case of sensitive skin or a potentially occurring eye-irritating effect of the surfactants. The same applies in particular to food. Consumer exposure to surfactants should be as low as possible. The present invention contributes to this.
- the emulsion according to the invention compared to the prior art resulted in less time spent cleaning.
- component I comprises 80 to 20% by weight of component II, which is an alkylpolyglucoside comprising 1-2 glucoside units and a hydrocarbon radical, in particular an alkyl radical of 6-16 C atoms. and further 20-80% by weight of component I 2 which is an alcohol-containing cosurfactant but not an alkylpolyglucoside.
- component II is an alkylpolyglucoside comprising 1-2 glucoside units and a hydrocarbon radical, in particular an alkyl radical of 6-16 C atoms.
- component I 2 which is an alcohol-containing cosurfactant but not an alkylpolyglucoside.
- the parts by weight relate only to the component I.
- the component I 2 is therefore not propylene glycol.
- component I 2 has an HLB value of 1-11 or of 3-11 or of 5-11 or of 1-5 or of 3-5.
- the HLB value describes the hydrophilic and lipophilic portion of a surfactant.
- the HLB value is calculated according to Griffin as follows [10]:
- surfactants of component I 2 which are skin-friendly are used in particular.
- examples are sorbitan esters.
- other surfactants emulsifiers which are permissible under food law can also be used.
- component II is more hydrophilic than component I 2 . This means that the HLB value of the component Ii is greater than that of the component I 2 .
- the mixture according to the invention can be produced such that component Ii has an HLB value of 11-19, in particular of 11-15 and component I 2 has an HLB value of 1-11, in particular 3-11 or 5- 11 or from 1-5 or 3-5.
- the component II according to the invention is according to claim 1, a polymeric additive comprising either a component Hi or H 2 or H 3 .

Additiv umfasst.Additive includes.
Die Erfindung betrifft eine Mischung, umfassend zwei Komponenten I und II, eine Emulsion, welche aus der Mischung hergestellt werden und auch als Mikroemulsion, insbesondere also eine bikontinuierliche Mikroemulsion, vorliegen kann, sowie einen Reiniger, ein Kosmetikartikel und ein Lebensmittel, welche die Emulsion umfassen und eine Verwendung des Reinigers.The invention relates to a mixture comprising two components I and II, an emulsion which are prepared from the mixture and may also be present as a microemulsion, in particular a bicontinuous microemulsion, and a cleaner, a cosmetic article and a foodstuff which comprise the emulsion and a use of the cleaner.
Tenside sind waschaktive Substanzen (Detergentien), die in Waschmitteln, Spülmitteln, und Shampoos enthalten sind. Sie verfügen über einen charakteristischen Aufbau und weisen mindestens eine hydrophile und eine hydrophobe Struktureinheit auf. Sie weisen einen amphiphilen Charakter auf. Steht der stabilisierende Charakter von Wasser-Öl-Gemischen im Vordergrund, werden diese amphiphilen Substanzen als Emulgatoren eingesetzt. Tenside setzen die Grenzflächenspannung zwischen miteinander nicht mischbaren Phasen, einer hydrophilen (wasserlöslichen, lipophoben), meist wässrigen Phase und einer hydrophoben (öllöslichen, lipophilen) Phase herab. Solche flüssigen Zwei-Phasen-Gemische werden als Emulsionen bezeichnet. Konventionelle Emulsionen können hydrophile und hydrophobe Phasen in unterschiedlichen Volumenanteilen enthalten. Sie haben eine kontinuierliche und eine disperse Phase, die als sehr kleine, durch Belegung mit Tensiden stabilisierte Kügelchen, in der kontinuierlichen Phase vorliegt. Je nach Natur der kontinuierlichen Phase spricht man von Öl-in-Wasser- oder Wasser-in-ÖI- Emulsionen.Surfactants are detergent substances (detergents) that are contained in detergents, dishwashing detergents, and shampoos. They have a characteristic structure and have at least one hydrophilic and one hydrophobic structural unit. They have an amphiphilic character. If the stabilizing character of water-oil mixtures is in the foreground, these amphiphilic substances are used as emulsifiers. Surfactants lower the interfacial tension between immiscible phases, a hydrophilic (water-soluble, lipophobic), mostly aqueous phase, and a hydrophobic (oil-soluble, lipophilic) phase. Such liquid two-phase mixtures are referred to as emulsions. Conventional emulsions may contain hydrophilic and hydrophobic phases in different volumes. They have a continuous and a disperse phase, which is a very small globule stabilized by surfactant occupancy, in the continuous phase. Depending on the nature of the continuous phase, it is referred to as oil-in-water or water-in-oil emulsions.
Grundsätzlich unterscheidet man zwischen Emulsionen und Mikroemulsionen. Während Mikroemulsionen thermodynamisch stabil sind, zerfallen Emulsionen aufgrund ihrer Instabilität. Im mikroskopischen Bereich spiegelt sich dieser Unterschied darin wieder, dass die emulgierten Flüssigkeiten in Mikroemulsionen in kleinere Flüssigkeitsvolumina (z. B. 10"15 μl_) gefasst sind
als in Emulsionen (z. B. 10"12 μl_) wie in DE 10 2005 049 765 Al beschrieben. Thermodynamisch instabile Emulsionen weisen somit größere Strukturen auf.Basically, a distinction is made between emulsions and microemulsions. While microemulsions are thermodynamically stable, emulsions disintegrate due to their instability. At the microscopic level, this difference is reflected in the fact that the emulsified liquids in microemulsions are enclosed in smaller volumes of liquid (eg 10 "15 μl_) as described in emulsions (eg 10 "12 μl_) as described in DE 10 2005 049 765 A. Thermodynamically unstable emulsions thus have larger structures.
In Mikroemulsionen können lamellare Mesophasen auftreten. Lamellare Mesophasen führen zu optischer Anisotropie und erhöhter Viskosität. Diese Eigenschaften sind z. B. für Reiniger unerwünscht. Außerdem tritt oft Phasentrennung auf, wenn lamellare Phasen mit Mikroemulsionen koexistieren.In microemulsions lamellar mesophases can occur. Lamellar mesophases lead to optical anisotropy and increased viscosity. These properties are for. B. undesirable for cleaners. In addition, phase separation often occurs when lamellar phases coexist with microemulsions.
Mikroemulsionen bestehen aus mindestens drei Komponenten, nämlich aus Öl, Wasser und einem Tensid [1-7]. Öl und Wasser sind nicht mischbar und bilden daher Domänen auf der Nanoskala. Das Tensid vermittelt zwischen diesen beiden Komponenten und erlaubt eine makroskopisch-homogene Mischung. Auf mikroskopischer Skala bildet das Tensid einen Film zwischen den Öl- und Wasserdomänen. Mikroemulsionen sind makroskopisch homogen, verhalten sich optisch isotrop und sind im Gegensatz zu Emulsionen thermodynamisch stabil. Es gibt W/O- und O/W-Tröpfchen-Mikroemulsionen, wobei Wassertröpfchen vom Öl oder Öltröpfchen vom Wasser umschlossen sind. Etwa gleiche Anteile von Öl zu Wasser fördern die Bildung einer bikontinuierlichen Mikroemulsion.Microemulsions consist of at least three components, namely oil, water and a surfactant [1-7]. Oil and water are immiscible and therefore form domains on the nanoscale. The surfactant mediates between these two components and allows a macroscopic-homogeneous mixture. On a microscopic scale, the surfactant forms a film between the oil and water domains. Microemulsions are macroscopically homogeneous, behave optically isotropically and are thermodynamically stable in contrast to emulsions. There are W / O and O / W droplet microemulsions in which water droplets from the oil or oil droplets are enclosed by the water. Approximately equal proportions of oil to water promote the formation of a bicontinuous microemulsion.
Charakteristisch für die Effizienz eines Tensids ist die minimal benötigte Tensidmenge, um Emulsionen über den gewünschten Zeitraum zu stabilisieren oder um eine Mikroemulsion zu erhalten.Characteristic of the efficiency of a surfactant is the minimum amount of surfactant required to stabilize emulsions over the desired period or to obtain a microemulsion.
Mikroemulsionen wurden intensiv im Bereich der Grundlagenwissenschaft untersucht [8, 9]. Die dabei erhaltenen Erkenntnisse beruhen weitgehend auf der Verwendung von reinen, definierten Komponenten : deionisiertes Wasser, chemisch reine Öle und Reintenside. Bei technischen Mikroemulsionen bestehen die Komponenten in der Regel aus Stoffgemischen. Dadurch ändert sich das Phasenverhältnis beträchtlich und die in vereinfachten Modellen gewonnenen Erkenntnisse aus der Grundlagenforschung können nicht ohne
weiteres auf technische Anwendungen übertragen werden. Eine weitere Schwierigkeit liegt in der geringen Temperaturstabilität von Mikroemulsionen, da in praxistauglichen Formulierungen die Stabilität über einen breiten Temperaturbereich hinweg gegeben sein muss. Besonders Systeme auf Basis der vielfach verwendeten Fettalkoholethoxylate sind nur in einem sehr engen Temperaturfenster von wenigen 0C stabil bzw. müssen extrem hohe Tensidkonzentrationen verwendet werden. Hingegen können Mikroemulsionen, die mit Hilfe von Zuckertensiden hergestellt werden, über größere Temperaturbereiche stabil sein. Ganz ähnlich können auch Gemische aus nichtionischen und ionische Tensiden herangezogen werden. Hier macht man sich das unterschiedliche Temperaturverhalten der nichtionischen und der ionischen Tenside zunutze. Allerdings weisen auch Zuckertenside und nichtionische Tensidmischungen Nachteile auf. Mikroemulsionen aus Zuckertensiden können nur mit Hilfe von Cotensiden hergestellt werden. Nach dem Stand der Technik werden dabei einwertige Alkohole wie Hexanol oder Octanol verwendet. Mikroemulsionen, die ionische Tenside beinhalten, sind empfindlich gegenüber Veränderungen der Salzkonzentration.Microemulsions have been extensively studied in the field of basic science [8, 9]. The knowledge gained is largely based on the use of pure, defined components: deionized water, chemically pure oils and pure surfactants. In technical microemulsions, the components usually consist of mixtures. As a result, the phase ratio changes considerably and the findings from basic research gained in simplified models can not be without further be transferred to technical applications. Another difficulty lies in the low temperature stability of microemulsions, since in practical formulations stability must be present over a wide temperature range. Particularly systems based on fatty alcohol ethoxylates frequently used are stable only in a very narrow temperature window of a few 0 C and extremely high levels of surfactant must be used. On the other hand, microemulsions made with the aid of sugar surfactants can be stable over larger temperature ranges. Similarly, mixtures of nonionic and ionic surfactants can be used. Here one makes use of the different temperature behavior of the nonionic and ionic surfactants advantage. However, sugar surfactants and nonionic surfactant mixtures also have disadvantages. Microemulsions of sugar surfactants can only be produced with the help of cosurfactants. In the prior art, monohydric alcohols such as hexanol or octanol are used. Microemulsions containing ionic surfactants are sensitive to changes in salt concentration.
Da die Forschung über Mikroemulsionen weitgehend im Bereich der Grundlagenforschung stattfindet, wurde in diesem Feld bislang wenig Wert darauf gelegt, Tenside zu verwenden, die ein geringes Gefahrstoffpotential beinhalten bzw. auf der Basis von nachwachsenden Rohstoffen hergestellt werden. Für technische Anwendungen kann dies von großer Bedeutung sein, da in konventionellen Mikroemulsionen Tensidgehalte von 20-30 % die Regel sind, um eine hinreichend ausgedehnte Temperaturstabilität zu erreichen. In solchen Konzentrationen besitzen Tenside ein nicht zu vernachlässigendesSince research on microemulsions takes place largely in the area of basic research, little emphasis has been placed in this area on the use of surfactants which contain a low risk potential or are produced on the basis of renewable raw materials. For technical applications, this can be of great importance, since in conventional microemulsions surfactant contents of 20-30% are the rule in order to achieve a sufficiently extended temperature stability. In such concentrations surfactants have a non-negligible
Gefahrstoffpotential. Sie wirken insbesondere reizend auf die Haut und Augen.Hazardous material potential. They are particularly irritating to the skin and eyes.
Eine Ausnahme in dieser Beziehung bilden Alkylpolyglucoside, die aus nachwachsenden Rohstoffen hergestellt werden und nur ein mäßiges Gefahrstoffpotential besitzen und zudem relativ hautfreundlich sind.An exception in this regard are alkyl polyglucosides which are produced from renewable raw materials and have only a moderate hazardous substance potential and are also relatively skin-friendly.
Sorbitanester hingegen, die ein sehr geringes Gefahrstoffpotential besitzen und auch weitgehend aus nachwachsenden Rohstoffen hergestellt werden,
sind hinsichtlich ihres Einsatzes in Mikroemulsionen bisher kaum erforscht worden.Sorbitan esters, on the other hand, which have a very low hazard potential and are also largely produced from renewable raw materials, have been little explored in terms of their use in microemulsions so far.

Im Gegensatz zu der erfindungsgemäßen Mischung wird kein zweites alkoholgruppen- enthaltendes Tensid offenbart.US-A-5719113 discloses detergents comprising an antibacterial substance, a nonionic surfactant and an amphoteric surfactant. In contrast to the mixture according to the invention, no second alcohol group-containing surfactant is disclosed.
Ein der Erfindung zugrunde liegendes technisches Problem besteht darin, eine Mischung zu schaffen, welche verbesserte Eigenschaften aufweist und zu einer Emulsion, insbesondere einer Mikroemulsion, verarbeitet werden kann.A technical problem underlying the invention is to provide a mixture which has improved properties and can be processed to form an emulsion, in particular a microemulsion.
Diese Emulsion, insbesondere Mikroemulsion, soll eine geringere Menge an Tensiden benötigen und in einem größeren Temperaturbereich stabil sein. In einer Ausführungsform weist die erfindungsgemäße Emulsion, insbesondere Mikroemulsion, den Vorteil auf, dass sie frei oder nahezu frei von flüchtigen organischen Verbindungen (sog. volatile organic Compounds, VOC) ist. Als VOC ist nach der 31. Verordnung zur Durchführung des Bundes- Immissionsschutzgesetzes (31. BimschV) § 2, Nr. 11, eine flüchtige organische Verbindung anzusehen, die bei 293,15 Kelvin einen Dampfdruck von 0,01 kPa oder mehr hat. Zu den VOC zählen z.B. Verbindungen der Stoffgruppen Alkane/Alkene, Aromaten, Terpene, Halogenkohlenwasserstoffe, Ester, Aldehyde und Ketone.This emulsion, especially microemulsion, should require a smaller amount of surfactants and be stable over a wider temperature range. In one embodiment, the emulsion according to the invention, in particular microemulsion, has the advantage that it is free or virtually free of volatile organic compounds (so-called volatile organic compounds, VOC). According to the 31st Ordinance for the Implementation of the Federal Pollution Control Act (31st BimschV), § 2, no. 11, is a volatile organic compound which has a vapor pressure of 0.01 kPa or more at 293.15 Kelvin. VOCs include e.g. Compounds of the substance groups alkanes / alkenes, aromatics, terpenes, halogenated hydrocarbons, esters, aldehydes and ketones.
Das Problem wird durch eine erfindungsgemäße Mischung gemäß Patentanspruch 1 gelöst.The problem is solved by a mixture according to claim 1 according to the invention.
Die erfindungsgemäße Mischung umfasst eine Komponente I, umfassend 80- 20 Gew.-% einer ersten tensidischen Komponente Ii, die ein Alkylpolyglucosid ist, umfassend 1-2 Glucosideinheiten und einen Kohlenwasserstoffrest, insbesondere einen Alkylrest von 6-16 C-Atomen, 20-80 Gew.-% einer Komponente I2, die ein Alkoholgruppen enthaltendes zweites Tensid
ausgenommen ein Alkylpolyglucosid ist, wobei sich die Gewichtsanteile nur auf die Komponente I beziehen, und polymeres Additiv als Komponente II, wobei das polymere Additiv als Komponente Hi mindestens eine wasserlösliche Einheit und mindestens eine hydrophobe Einheit umfasst, wobei das Verhältnis der zahlenmittleren Molekulargewichte aller wasserlöslichen Einheiten und der zahlenmittleren Molekulargewichte aller hydrophoben Einheiten 2: 1 bis 1000 : 1 oder 3: 1 bis 1000: 1, insbesondere 5 : 1 bis 200: 1 und insbesondere 10: 1 bis 50: 1 beträgt und wobei jede mindestens eine hydrophobe Einheit ein zahlenmittleres Molekulargewicht von maximal 1000 g/mol besitzt, oder das polymere Additiv als Komponente H2 mindestens eine wasserlösliche Einheit und mindestens eine hydrophobe Einheit umfasst, wobei es ein amphiphiles Kammpolymer ist, welches ein Rückgrat mit am Rückgrat angebrachten zwei oder mehreren Seitenketten umfasst, wobei sich die Seitenketten untereinander und/oder die Seitenketten vom Rückgrat in ihrem amphiphilen Charakter unterscheiden, oder das polymere Additiv als Komponente H3 mindestens eine wasserlösliche Einheit und mindestens eine hydrophobe Einheit umfasst, wobei das polymere Additiv als Komponente H3 ein AB-Diblockcopolymer oder ein ABA- bzw. BAB- Triblockcoplymer mit wasserlöslichen Blöcken A und hydrophoben Blöcken B ist.The mixture according to the invention comprises a component I comprising 80-20% by weight of a first surface-active component Ii which is an alkyl polyglucoside comprising 1-2 glucoside units and a hydrocarbon radical, in particular an alkyl radical of 6-16 C atoms, 20-80 % By weight of a component I 2 containing a second surfactant containing alcohol groups excluding an alkyl polyglucoside, wherein the parts by weight relate only to the component I, and polymeric additive as component II, wherein the polymeric additive comprises as component Hi at least one water-soluble unit and at least one hydrophobic unit, wherein the ratio of the number average molecular weights of all water-soluble units and the number average molecular weights of all hydrophobic units is 2: 1 to 1000: 1 or 3: 1 to 1000: 1, in particular 5: 1 to 200: 1 and in particular 10: 1 to 50: 1 and wherein each at least one hydrophobic unit is a number average Molecular weight of at most 1000 g / mol, or the polymeric additive comprises, as component H 2 at least one water-soluble unit and at least one hydrophobic moiety, wherein it is an amphiphilic comb polymer comprising a backbone with two or more side chains attached to the backbone the side chains with each other and / or the Sei differ from the backbone in their amphiphilic character, or the polymeric additive comprises as component H 3 at least one water-soluble unit and at least one hydrophobic moiety, wherein the polymeric additive as component H 3 is an AB diblock copolymer or an ABA or BAB triblock copolymer with water-soluble blocks A and hydrophobic blocks B is.
Das polymere Additiv der Komponenten Hi, H2 oder H3 kann auch in Kombination in der Mischung vorliegen.The polymeric additive of the components Hi, H 2 or H 3 may also be present in combination in the mixture.
Diese Komponente II, die als polymeres Additiv in der Mischung gemäß Patentanspruch 1 enthalten ist, scheint zu einer Effizienzsteigerung der Tenside in Komponente I zu führen.This component II, which is included as a polymeric additive in the mixture according to claim 1, seems to lead to an increase in the efficiency of the surfactants in component I.
Neben Kostengründen ist die Tensideinsparung auch aus ökologischen oder gesundheitlichen Gründen vorteilhaft. Tenside sind ökologisch besonders relevante Stoffe, deren Umweltverträglichkeit sichergestellt werden muss.
Ein weiterer Vorteil der Einsparung von Tensiden tritt in Erscheinung, wenn sich Tenside bei der Anwendung der Mikroemulsion störend auswirken. Beispielhaft können Kosmetika genannt werden, deren Tensidgehalt aufgrund der möglicherweise bei empfindlicher Haut auftretenden hautbeeinflussenden Wirkung oder einer möglicherweise auftretenden augenreizenden Wirkung der Tenside möglichst gering sein sollte. Gleiches gilt in besonderem Maße für Lebensmittel. Eine Belastung des Konsumenten durch Tenside sollte so niedrig wie möglich sein. Die vorliegende Erfindung leistet dazu einen Beitrag.In addition to cost reasons, the surfactant saving is also advantageous for environmental or health reasons. Surfactants are ecologically particularly relevant substances whose environmental compatibility must be ensured. Another advantage of surfactant savings occurs when surfactants interfere with the application of the microemulsion. By way of example, cosmetics may be mentioned whose surfactant content should be as low as possible due to the skin-influencing effect possibly occurring in the case of sensitive skin or a potentially occurring eye-irritating effect of the surfactants. The same applies in particular to food. Consumer exposure to surfactants should be as low as possible. The present invention contributes to this.
In einer Ausführungsform führte die erfindungsgemäße Emulsion gegenüber dem Stand der Technik zu einem geringeren Zeitaufwand beim Abreinigen.In one embodiment, the emulsion according to the invention compared to the prior art resulted in less time spent cleaning.
Die erfindungsgemäße Mischung umfasst die Komponenten I und II. Komponente I umfasst ihrerseits 80 - 20 Gew.-% Komponente Ii, welche ein Alkylpolyglucosid ist, das 1-2 Glucosideinheiten und einen Kohlenwasserstoffrest, insbesondere einen_Alkylrest von 6-16 C-Atomen, umfasst, und des weiteren 20 - 80 Gew.-% der Komponente I2, welche ein Alkoholgruppen enthaltendes Cotensid, aber kein Alkylpolyglucosid ist. Die Gewichtsanteile beziehen sich dabei nur auf die Komponente I.The mixture according to the invention comprises components I and II. In turn, component I comprises 80 to 20% by weight of component II, which is an alkylpolyglucoside comprising 1-2 glucoside units and a hydrocarbon radical, in particular an alkyl radical of 6-16 C atoms. and further 20-80% by weight of component I 2 which is an alcohol-containing cosurfactant but not an alkylpolyglucoside. The parts by weight relate only to the component I.
Erfindungsgemäß ist die Komponente I2 folglich nicht Propylenglykol.According to the invention, the component I 2 is therefore not propylene glycol.
Komponente I2 weist in einer Ausführungsform der erfindungsgemäßen Mischung in wässriger Lösung einen HLB-Wert von 1-11 oder von 3-11 oder von 5-11 oder von 1-5 oder von 3-5 auf. Der HLB-Wert beschreibt den hydrophilen und lipophilen Anteil eines Tensids.In an embodiment of the mixture according to the invention in aqueous solution, component I 2 has an HLB value of 1-11 or of 3-11 or of 5-11 or of 1-5 or of 3-5. The HLB value describes the hydrophilic and lipophilic portion of a surfactant.
Der HLB-Wert wird nach Griffin wie folgt berechnet [10] :The HLB value is calculated according to Griffin as follows [10]:
HLB= 20 * Mh/M
Mh = Molmasse des hydrophilen Anteils eines Moleküls M = Molmasse des gesamten MolekülsHLB = 20 * M H / M M h = molecular weight of the hydrophilic portion of a molecule M = molecular weight of the entire molecule
Erfindungsgemäß werden insbesondere Tenside der Komponente I2 eingesetzt, die hautfreundlich sind. Als Beispiele sind Sorbitanester zu nennen. Daneben können aber auch andere, gemäß Lebensmittelrecht zulässige Tenside (Emulgatoren) eingesetzt werden.According to the invention, surfactants of component I 2 which are skin-friendly are used in particular. Examples are sorbitan esters. In addition, however, other surfactants (emulsifiers) which are permissible under food law can also be used.
In einer Ausführungsform der erfindungsgemäßen Mischung ist Komponente Ii hydrophiler als Komponente I2. Dies bedeutet, dass der HLB-Wert der Komponente Ii größer ist als der der Komponente I2.In one embodiment of the mixture according to the invention, component II is more hydrophilic than component I 2 . This means that the HLB value of the component Ii is greater than that of the component I 2 .
Beispielsweise kann die erfindungsgemäße Mischung so hergestellt sein, dass die Komponente Ii einen HLB-Wert von 11-19, insbesondere von 11-15 aufweist und die Komponente I2 einen HLB-Wert von 1-11, insbesondere von 3-11 oder 5-11 oder von 1-5 oder 3-5 aufweist.For example, the mixture according to the invention can be produced such that component Ii has an HLB value of 11-19, in particular of 11-15 and component I 2 has an HLB value of 1-11, in particular 3-11 or 5- 11 or from 1-5 or 3-5.
Die erfindungsgemäße Komponente II ist gemäß Anspruch 1 ein polymeres Additiv, das entweder eine Komponente Hi oder H2 oder H3 umfasst. Komponente Hi umfasst weiterhin mindestens eine wasserlösliche Einheit und mindestens eine hydrophobe Einheit, wobei das Verhältnis der zahlenmittleren Molekulargewichte aller wasserlöslichen Einheiten und der zahlenmittleren Molekulargewichte aller hydrophoben Einheiten 2: 1 bis 1000: 1, insbesondere 5: 1 bis 200: 1 und besonders 10: 1 bis 50: 1 beträgt und wobei jede mindestens eine hydrophobe Einheit ein zahlenmittleres Molekulargewicht von maximal 1000 g/mol besitzt.The component II according to the invention is according to claim 1, a polymeric additive comprising either a component Hi or H 2 or H 3 . Component Hi furthermore comprises at least one water-soluble unit and at least one hydrophobic unit, the ratio of the number-average molecular weights of all water-soluble units and the number average molecular weights of all hydrophobic units being 2: 1 to 1000: 1, in particular 5: 1 to 200: 1 and especially 10: 1 to 50: 1 and wherein each at least one hydrophobic unit has a number average molecular weight of at most 1000 g / mol.
Die Komponente H2 umfasst ebenfalls mindestens eine wasserlösliche Einheit und mindestens eine hydrophobe Einheit. Es handelt sich um ein amphiphiles Kammpolymer, welches ein Rückgrat mit am Rückgrat angebrachten zwei oder mehreren Seitenketten umfasst, wobei sich die Seitenketten untereinander und/oder die Seitenketten vom Rückgrat in ihrem amphiphilen Charakter unterscheiden.
Die Komponente H3 umfasst mindestens eine wasserlösliche Einheit und mindestens eine hydrophobe Einheit, wobei sie ein AB-Diblockcopolymer oder ein ABA- bzw. BAB-Triblockcoplymer mit wasserlöslichen Blöcken A und hydrophoben Blöcken B ist.The component H 2 likewise comprises at least one water-soluble unit and at least one hydrophobic unit. It is an amphiphilic comb polymer comprising a backbone with two or more side chains attached to the backbone, the side chains differing from each other and / or the side chains from the backbone in their amphiphilic character. The component H 3 comprises at least one water-soluble unit and at least one hydrophobic unit, being an AB diblock copolymer or an ABA or BAB triblock copolymer having water-soluble blocks A and hydrophobic blocks B.
In einer weiteren Ausführungsform umfasst die erfindungsgemäße Mischung 80-99 Gew.-% Komponente I, insbesondere 85-95 Gew.-%, und 1-20 Gew.-% Komponente II, insbesondere 5-15 Gew.-%.In a further embodiment, the mixture according to the invention comprises 80-99% by weight of component I, in particular 85-95% by weight, and 1-20% by weight of component II, in particular 5-15% by weight.
Eine Emulsion erhältlich durch Verdünnen der erfindungsgemäßen Mischung mit wässriger Lösung und öliger Phase ist ebenfalls Gegenstand dieser Erfindung. Es kommt dabei zur Bildung einer Emulsion zwischen hydrophiler und hydrophober Phase, welche durch die erfindungsgemäße Mischung stabilisiert wird.An emulsion obtainable by diluting the aqueous solution-oily phase mixture of the present invention is also an object of this invention. This results in the formation of an emulsion between hydrophilic and hydrophobic phase, which is stabilized by the mixture according to the invention.
In einer Ausführungsform ist diese Emulsion dadurch gekennzeichnet, dass es sich um eine Mikroemulsion handelt, welche insbesondere eine bikontinuierliche Mikroemulsion ist. Bikontinuierliche Mikroemulsionen umfassen zwei Phasen, eine hydrophobe und eine hydrophile Phase, in Form von ausgedehnten nebeneinanderliegenden und ineinander verschlungenen Domänen, an deren Grenzfläche stabilisierende grenzflächenaktive Tenside in einer monomolekularen Schicht angereichert sind (vgl. [H]). Mikroemulsionen bilden sich sehr leicht und wegen der sehr niedrigen Grenzflächenspannung spontan, wenn die Einzelkomponenten Wasser, Öl und ein geeignetes grenzflächenaktives System vermischt werden. Da die Domänen in mindestens einer Dimension nur sehr geringe Ausdehnungen in der Größenordnung von Nanometern haben, erscheinen Mikroemulsionen oft visuell transparent und sind je nach dem eingesetzten grenzflächenaktiven System in einem bestimmten Temperaturbereich thermodynamisch, d. h. zeitlich unbegrenzt, stabil. Wenn Mikroemulsionen geringe Tensidgehalte aufweisen, können sie auch trüb sein.
In einer anderen Ausführungsform kann die erfindungsgemäße Mikroemulsion eine W/O- oder O/W- Tröpfchen-Mikroemulsion sein, wobei Wassertröpfchen vom Öl oder Öltröpfchen vom Wasser umschlossen sind.In one embodiment, this emulsion is characterized in that it is a microemulsion, which is in particular a bicontinuous microemulsion. Bicontinuous microemulsions comprise two phases, a hydrophobic and a hydrophilic phase, in the form of extended juxtaposed and intertwined domains, at the interface of which stabilizing surface-active surfactants are enriched in a monomolecular layer (see [H]). Microemulsions form very easily and spontaneously because of the very low interfacial tension when the individual components water, oil and a suitable surfactant system are mixed. Since the domains in at least one dimension have only very small dimensions on the order of nanometers, microemulsions often appear visually transparent and are thermodynamically, ie indefinitely, stable depending on the surfactant system used in a specific temperature range. If microemulsions have low surfactant contents, they can also be cloudy. Alternatively, the microemulsion of the present invention may be a W / O or O / W droplet microemulsion wherein water droplets from the oil or oil droplets are surrounded by the water.
Das geeignete Massenverhältnis von öliger Phase zu wässriger Phase hängt stark vom Anwendungsgebiet ab und kann vom Fachmann in Routineversuchen optimiert werden. So kann beispielsweise im Bereich Pflanzenschutz ein Verhältnis von 0,01 und im Bereich Haushaltsreiniger ein Verhältnis von 0,7 zufriedenstellende Ergebnisse liefern.The suitable mass ratio of oily phase to aqueous phase depends strongly on the field of application and can be optimized by the person skilled in the art in routine experiments. For example, in the field of crop protection, a ratio of 0.01 and in the area of household cleaners a ratio of 0.7 can provide satisfactory results.
In einer weiteren Ausführungsform der erfindungsgemäßen Mikroemulsion beträgt das Massenverhältnis von öliger Phase zu wässriger Phase 0,5 bis 1,6. Solche Verhältnisse sind bei Industriereinigern sinnvoll.In a further embodiment of the microemulsion according to the invention, the mass ratio of oily phase to aqueous phase is 0.5 to 1.6. Such conditions are useful for industrial cleaners.
In einer anderen Ausführungsform des erfindungsgemäßen Reinigers beträgt das Massenverhältnis von öliger Phase zu wässriger Phase der Mikroemulsion 1,0 bis 1,4.In another embodiment of the cleaner according to the invention, the mass ratio of oily phase to aqueous phase of the microemulsion is 1.0 to 1.4.

B. diethylene glycol monobutyl ether or dipropylene glycol dimethyl ether. The oily phase of the emulsion may further comprise triglycerides and products

B. from plants or semi-volatile hydrocarbon oils, especially aliphatic hydrocarbons, an almost odor-neutral emulsion can be prepared.

Für die aufgeführten Reinigungszwecke, insbesondere im Offsetdruck, fallen im regulären Produktionsbetrieb kontinuierlich Reinigungsarbeiten an. Diese werden entweder durch manuelle Reinigung oder unter Einsatz automatischer Reinigungsanlagen ausgeführt. Die eingesetzten Reiniger umfassen organische Lösungsmittel. Vor längeren Produktionsunterbrechungen (z. B. Wochenende) werden die farbführenden Teile der Maschine mit Hilfe von Lösungsmitteln
gereinigt. Zudem müssen Druckformen, besonders Flachdruckformen, bei einer Unterbrechung des Druckprozesses sorgfältig von Farbrückständen befreit werden. Neben den Gummituchwaschanlagen sind neuere Druckanlagen teilweise auch mit Farbwerk-Wascheinrichtungen ausgestattet. Ansonsten wird manuell mit Hilfe von Putztüchern gereinigt. Im Rahmen von Instandhaltungs- und Wartungsarbeiten werden periodisch auch die Wischwassersysteme der Druckanlagen entleert und gereinigt.For the listed cleaning purposes, especially in offset printing, cleaning operations are carried out in regular production operation. These are carried out either by manual cleaning or by using automatic cleaning systems. The cleaners used include organic solvents. Before prolonged production interruptions (eg weekends), the ink-bearing parts of the machine with the help of solvents cleaned. In addition, printing forms, especially planographic printing forms, must be carefully freed from ink residues when the printing process is interrupted. In addition to the blanket washing systems, some of the newer printing systems are also equipped with inking unit washing facilities. Otherwise it is cleaned manually with the help of cleaning cloths. As part of maintenance and service work, the wiper water systems of the pressure equipment are periodically emptied and cleaned.

They lead to "run-flat" of the ink rollers and "blind run" of the printing plates. With conventional surfactant mixtures such residues can not be removed.
Im Offsetdruck sind je nach Betriebszustand und Anforderungen bei Auftragswechsel Farbwerk, Druckplatte, Gummituch auf dem Gummizylinder und der Gegendruckzylinder zu reinigen. Zur Reinigung des Farbwerks und der Zylinderoberflächen stehen automatische Waschanlagen zur Verfügung, die sich in der Art ihrer technischen Ausführung unterscheiden. Bei einer Bürstenwascheinrichtung erfolgt die Reinigung mit Hilfe einer Bürstenwalze. Über diese wird zugeführte Reinigungsflüssigkeit an die zu reinigende Oberfläche (Gummi-, Gegendruckzylinder und Farbwerk) übertragen. Das Tuch der Tuchwascheinrichtung wird fein dosiert über z. B. Düsenleisten mit
Reinigungsflüssigkeit versorgt. Das Reinigungstuch liegt angepresst auf der zu reinigende Oberfläche (Gummi-, Gegendruckzylinder und Farbwerk).In offset printing, the inking unit, printing plate, rubber blanket on the blanket cylinder and the impression cylinder are to be cleaned depending on the operating status and requirements when changing jobs. For cleaning the inking unit and the cylinder surfaces are available automatic washing systems, which differ in the nature of their technical design. In a brush washer, the cleaning is done by means of a brush roller. About this supplied cleaning fluid is transferred to the surface to be cleaned (rubber, impression cylinder and inking unit). The cloth of the cloth washing device is finely dosed over z. B. nozzle strips with Supplied cleaning fluid. The cleaning cloth is pressed against the surface to be cleaned (rubber, impression cylinder and inking unit).

Die Temperaturstabilität der Mikroemulsionen wurde in einem thermostatisierten Wasserbad durch visuelle Begutachtung im Durchlicht bestimmt. Dazu wurden die Gemische in geschlossenen, zylinderförmigen Glasgefäßen von ca. 5-15 mm Durchmesser untersucht, bei hoher Trübheit der Mikroemulsionen wurden Küvetten von 1 mm Schichtdicke verwendet. Die Temperatur-Phasengrenzen des einphasigen Mikroemulsionsbereichs konnten
aufgrund der drastisch ansteigenden Trübheit bei Über- oder Unterschreiten des Stabilitätsfensters erkannt werden. Lamellare Phasen wurden mit Hilfe von gekreuzten Polarisatoren bestimmt. In den für die Beispiele angegebenen Stabilitätsbereichen liegen grundsätzlich einphasige Mikroemulsionen vor, die keine lamellare Phasen beinhalten.The temperature stability of the microemulsions was determined in a thermostated water bath by visual inspection in transmitted light. For this purpose, the mixtures were investigated in closed, cylindrical glass vessels of about 5-15 mm in diameter, at high turbidity of the microemulsions cuvettes were used of 1 mm layer thickness. The temperature phase boundaries of the single-phase microemulsion region could due to the drastically increasing turbidity when exceeding or falling below the stability window. Lamellar phases were determined by crossed polarizers. In the stability ranges given for the examples, there are basically single-phase microemulsions which do not contain any lamellar phases.

Im Rahmen eines vergleichenden Versuchs wurden die Gummitücher einer Rotations-Offsetdruckmaschine mit handelsüblicher Offsetdruckfarbe (Fa. Huber) auf Ölbasis einmal mit einem auf organischem Lösungsmittel basierendem Reiniger (in der Hauptsache aliphatische Kohlenwasserstoffe, Testbenzine) und einmal mit der erfindungsgemäßen Mikroemulsion gereinigt. Die Reinigungsleistung, d. h. die Abreinigung der Druckfarbe, sowie des Papierstaubaufbaus, d. h. die festen Rückstände aus Papierfasern, war im Wesentlichen gleich. Nach der Reinigung waren die Walzen sauberer und trockener als bei Verwendung von organischen Lösungsmitteln als Reinigungsmittel, was eine reduzierte Anfahrmakulatur zur Folge hatte. Bei Verwendung der Mikroemulsion war der Arbeitsaufwand beim manuellen Abreinigen der Gummitüchern geringer.As part of a comparative experiment, the blankets of a rotary offset printing machine with commercial offset printing ink (Huber) were cleaned once with an organic solvent-based cleaner (mainly aliphatic hydrocarbons, white spirit) and once with the microemulsion of the invention. The cleaning performance, d. H. the cleaning of the ink, as well as the paper dust build-up, d. H. the solid residues of paper fibers were essentially the same. After cleaning, the rollers were cleaner and drier than using organic solvents as cleaning agents, resulting in reduced start-up waste. When using the microemulsion, the labor required to manually clean the blankets was lower.
