Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung flüssiger Reinigungs- oder Waschmittelzusammensetzungen, die im Ruhezustand in wenigstens zwei wäßrige Phasen getrennt vorliegen.The present invention relates to a process for the preparation of liquid cleaning or Detergent compositions which at rest in at least two aqueous phases present separately.
Sowohl bei der Reinigung harter Oberflächen, insbesondere im Küchen- oder Sanitärbereich, als auch beim Waschen von verschmutzten Geweben stellt sich oft das Problem, daß sowohl anorganische als auch organische Verschmutzungen entfernt werden müssen. Während zur Entfernung der meist organischen Verschmutzungen üblicherweise Tenside eingesetzt werden. sind diese gegenüber anorganischen Verschmutzungen normalerweise weniger wirkungsvoll und sogar oft gänzlich wirkungslos.Both when cleaning hard surfaces, especially in the kitchen or sanitary area, as well as when washing soiled tissues often poses the problem that both inorganic as well as organic soiling must be removed. While to Removal of mostly organic contaminants usually surfactants are used. these are usually less effective against inorganic contaminants and often completely ineffective.
Zur Beseitigung anorganischer Verschmutzungen ist es daher erforderlich, Verbindungen, meist in wäßriger Lösung, einzusetzen, die zum Auf- oder Ablösen dieser Verschmutzungen geeignet sind. Dies können je nach Art der Verschmutzung saure, neutrale oder alkalische Verbindungen sein.To eliminate inorganic contamination, it is therefore necessary to use compounds, mostly in aqueous solution, to use, the up or detachment of these contaminants are suitable. These can be acidic, neutral or alkaline depending on the nature of the pollution Be connections.
Zur Auflösung von Kalksteinablagerungen. die üblicherweise auf Härtebildner des Wassers zurückzuführen sind, werden bevorzugt saure wäßrige Lösungen eingesetzt. Zur Beseitigung anderer organischer, bspw. tonhaltiger und/oder pigmenthaltiger, Verschmutzungen sind eher wäßrige Lösungen mit Inhaltsstoffen geeignet, die in wäßriger Lösung einen pH-Wert im neutralen oder alkalischen Bereich zur Folge haben.For the dissolution of limestone deposits. usually on hardness of water are attributable to acidic aqueous solutions are preferably used. For elimination other organic, for example, clay-containing and / or pigment-containing, soils are more likely aqueous solutions containing ingredients which in aqueous solution have a pH in the neutral or alkaline area.
In beiden Fällen ist allerdings festgestellt worden, daß der Zusatz von Tensiden zu wäßrigen Lösungen, die zur Entfernung von anorganischen Verschmutzungen gedacht sind. - um mit diesen dann auch organische Verschmutzungen beseitigen zu können - zu einer deutlichen Verringerung von deren Leistung gegenüber anorganischen Verschmutzungen führen kann. In both cases, however, it has been found that the addition of surfactants to aqueous Solutions designed to remove inorganic contaminants. - with then be able to eliminate these organic soiling - a clear Reduction of their performance against inorganic contaminants can lead.
In der (nicht vorveröffentlichten) eigenen älteren Anmeldung 198 49 247.2 ist zur Lösung dieser Aufgabe eine flüssige Reinigungs- oder Waschmittelzusammensetzung vorgeschlagen werden, die im Ruhezustand in wenigstens zwei wäßrige Phasen getrennt vorliegt. Bei einer derartigen Zusammensetzung kommt es zu einer unerwarteten Verbesserung der Reinigungswirkung, wobei insbesondere die duale Wirkung sowohl gegen organische als auch anorganische Verschmutzungen gewährleistet ist. Wenn eine solche Zusammensetzung vor oder während des Gebrauchs geschüttelt oder durchmischt wird, ergibt sich eine Dispersion, die ein homogenes Aufbringen auf die Oberfläche bzw. das Substrat ermöglicht. Sowohl auf der Oberfläche bzw. dem Substrat als auch im Vorratsbehältnis trennt sich diese Dispersion im Ruhezustand relativ rasch wieder. um getrennte wäßrige Phasen auszubilden.In the (not previously published) own older application 198 49 247.2 is the solution this task proposed a liquid cleaning or detergent composition which, when at rest, is present separately in at least two aqueous phases. At a such composition results in an unexpected improvement of the cleaning effect, in particular the dual action against both organic and inorganic Pollution is ensured. If such a composition before or during shaken or mixed in use, resulting in a dispersion, the allows homogeneous application to the surface or the substrate. Both on the Surface or the substrate as well as in the storage container, this dispersion separates in Hibernation relatively quickly again. to form separate aqueous phases.
Aufgrund der Tatsache, daß diese Produkte im Ruhezustand aus wenigstens zwei flüssigen Phasen im Gleichgewicht bestehen, ergeben sich besondere Schwierigkeiten bei ihrer Herstellung. Wenn die Produkte in Chargen in einem Flüssigkeitsmischer hergestellt werden, müssen alle an das Mischen anschließenden Vorgänge (wie bspw. Transport, Lagerung, Abfüllung, etc.) mit dem gemischten Produkt durchführt werden, das - bestimmungsgemäß - in jeder Ruhephase dazu neigt, den Gleichgewichtszustand der getrennten wäßrigen Phasen anzunehmen. Dadurch ist es schwierig sicherzustellen, daß die relative Menge jeder der mehreren, vorzugsweise zwei Phasen, über die Zeit konstant bleibt.Due to the fact that these products at rest from at least two liquid Phases in equilibrium, there are particular difficulties in their preparation. If the products are produced in batches in a fluid mixer, All operations subsequent to mixing (such as transport, storage, filling, etc.) with the mixed product, which - as intended - in each quiescent phase tends to the equilibrium state of the separated aqueous phases to accept. This makes it difficult to ensure that the relative amount of each of the several, preferably two phases, over which time remains constant.
Hierzu wäre es erforderlich. während des gesamten Herstellungsverfahrens, d.h. auch während des Transportes, der Lagerung, der Abfüllung, etc., eine kontinuierliche Mischung vorzusehen, um für Produkthomogenität zu sorgen, die ihrerseits Voraussetzung ist, damit das abgefüllte Endprodukt wunschgemäß die getrennten wäßrigen Phasen im richtigen vorbestimmten Volumenverhältnis ausbildet.For this it would be necessary. throughout the manufacturing process, i. even while transport, storage, filling, etc., to provide a continuous mixture, to ensure product homogeneity, which in turn is a prerequisite for the bottled end product as desired, the separate aqueous phases in the correct predetermined Volume ratio forms.
Diese Lösung würde besondere anlagenmäßige Aufwendungen bzw. Beschränkungen mit sich bringen. Übliche Abfüllvorrichtungen, z.B. die Zudosierung über volumetrische Zylinder. wären ungeeignet. Aber selbst dann. wenn alle Anlagenteile dem Erfordernis einer kontinuierlichen Durchmischung Rechnung tragen würden. würden sich Haltezeiten der Anlage als ausgesprochen problematisch erweisen. da in diesen Haltezeiten die im System (Leitungen. This solution would involve special asset related expenses or restrictions to bring oneself. Common filling devices, e.g. the metering via volumetric cylinders. would be inappropriate. But even then. if all plant components meet the requirement of a continuous Mixing would take into account. would hold the plant as extremely problematic. because in these holding times in the system (lines.
Abfüllsystem, etc.) verbliebenen Produktvolumina, die im Endprodukt erwünschte Phasentrennung durchlaufen würden.Filling system, etc.) remaining product volumes, the desired phase separation in the final product would go through.
Auch die Alternative der separaten Formulierung und Abfüllung der mehreren, vorzugsweise zwei Phasen, so daß das mehrphasige Produkt erst in diesem Stadium erhalten wird, stellt keine befriedigende Lösung des beschriebenen Problems dar, da jede der zwei Phasen am Gleichgewichtspunkt liegt und daher jede geringfügige Änderung in z.B. Druck, Temperatur, etc. das Gleichgewicht so beeinflussen könnte, daß entsprechende mehrphasige Vorprodukte entstehen würden, bei denen sich die gleichen Verarbeitungsschwierigkeiten stellen würden, wie oben beschrieben.Also, the alternative of separate formulation and filling of the plurality, preferably two phases, so that the multiphase product is obtained only at this stage provides not a satisfactory solution to the problem described, since each of the two phases on Equilibrium point and therefore any slight change in e.g. Pressure, temperature, etc. could influence the equilibrium so that corresponding multiphase precursors would arise where the same processing difficulties would arise, as described above.
In EP-A-0 116 422 wird ein Verfahren zur Herstellung von mehrphasigen Haarshampoos beschrieben, bei dem drei separate Komponenten vorgemischt werden, bevor sie den restlichen Komponenten der Zusammensetzung zugefügt werden können. In US-A-4 348 292 und WO 99 47635 A wird ein mehrphasiges, wäßriges Reinigungs- oder Waschmittel durch Aufmischen aus seinen Rohstoffen, anschließendes Durchmischen und abschließendes Stehen des Mittels zur Auftrennung der temporären Emulsion hergestellt.EP-A-0 116 422 discloses a process for the preparation of multi-phase hair shampoos described in the three separate components are premixed before they added to remaining components of the composition can be. In US-A-4 348 292 and WO 99 47635 A is a multi-phase, aqueous cleaning or Detergent by blending from its raw materials, subsequent mixing and final standing the means for separating the temporary emulsion produced.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung der gattungsgemäßen Zusammensetzungen zur Verfügung zu stellen, das die genannten Probleme überwindet.The invention is therefore based on the object, a method for producing the generic To provide compositions that overcomes these problems.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß wenigstens zwei getrennte Vormischungen hergestellt werden, die im Temperaturbereich von 0°C bis 40°C keine Phasentrennung zeigen, und diese Vormischungen erst bei oder unmittelbar vor der Abfüllung in das Verpackungsbehältnis miteinander vermischt werden.According to the invention, this object is achieved in that at least two separate premixes be prepared in the temperature range of 0 ° C to 40 ° C no phase separation and these premixes only at or immediately before bottling Packaging container are mixed together.
Bevorzugt ist dabei die Zusammensetzung jeder Vormischung verschieden von der Zusammensetzung jeder der getrennten wäßrigen Phasen im Ruhezustand des Endproduktes.Preferably, the composition of each premix is different from the composition each of the separated aqueous phases at rest of the final product.
In einer besonderen Ausführungsform der Erfindung ist vorgesehen, daß eine erste Vormischung. neben dem Hauptbestandteil Wasser, diejenige(n) Substanz(en) der Gesamtzusammensetzung enthält, bei deren Weglassen die Ausbildung von getrennten wäßrigen Phasen der Gesamtzusammensetzung im wesentlichen unterbleibt, wobei die restlichen Inhaltsstoffe der Gesamtzusammensetzung in einer zweiten Vormischung, ebenfalls zusammen mit dem Hauptbestandteil Wasser, enthalten sind. In a particular embodiment of the invention it is provided that a first premix. besides the main constituent water, the substance (s) of the total composition contains, omitting the formation of separate aqueous phases of the Substance is substantially omitted, the remaining ingredients of the Total composition in a second premix, also together with the Main ingredient water, are included.
Dabei kann die erste Vormischung, falls in der Gesamtzusammensetzung vorhanden, beispielsweise eine hydrophobe Substanz oder eine Substanz, die zusammen mit einer oder mehreren weiteren Substanzen der Gesamtzusammensetzung eine hydrophobe Substanz bildet, enthalten, wobei es sich dabei, falls in der Gesamtzusammensetzung vorhanden, insbesondere um einen oder mehrere Duftstoffe, einen oder mehrere hydrophobe wasserunlösliche Lösemittel und/oder, wenn in der Gesamtzusammensetzung sowohl ein oder mehrere quartäre Ammoniumsalze als auch ein oder mehrere Sulfate vorhanden sind, eine dieser beiden Substanzgruppen handeln kann.In this case, the first premix, if present in the overall composition, for example a hydrophobic substance or a substance that together with one or more further substances of the total composition forms a hydrophobic substance, which, if present in the overall composition, in particular one or more fragrances, one or more hydrophobic water-insoluble solvents and / or, if in the overall composition both one or more quaternary Ammonium salts and one or more sulfates are present, one of these two groups of substances can act.
In anderen Zusammensetzungen kann die erste Vormischung, falls in der Gesamtzusammensetzung vorhanden, insbesondere eine oder mehrere wasserlösliche Substanzen mit niedrigem Trübungspunkt enthalten, wobei es sich hierbei beispielsweise um ein oder mehrere quartäre Ammoniumsalze und/oder ein oder mehrere Tenside auf der Basis von Ethylenoxid und/oder Propylenoxid handeln kann.In other compositions, the first premix, if in the overall composition present, in particular one or more water-soluble substances with low Cloud point, which is, for example, one or more quaternary Ammonium salts and / or one or more surfactants based on ethylene oxide and / or Propylene oxide can act.
Bevorzugt ist vorgesehen, daß die erste Vormischung und die zweite Vormischung vor dem Vermischen in einem Volumenverhältnis von 5/95 bis 50/50 vorliegen.It is preferably provided that the first premix and the second premix before the Mixing in a volume ratio of 5/95 to 50/50 are present.
Überraschenderweise können auf dem vorgeschlagenen Weg in einfacher und wirkungsvoller Weise die eingangs genannten Probleme vermieden werden. Dabei stellt es für den Fachmann keine Schwierigkeit dar, diejenigen Verbindungen in der Gesamtzusammensetzung zu identifizieren, die einerseits für sich genommen zusammen mit Wasser eine stabile Zusammensetzung ergeben und andererseits ermöglichen, daß die restlichen Inhaltsstoffe der Gesamtzusammensetzung ebenfalls zusammen mit Wasser eine stabile Zusammensetzung ergeben. wobei der Begriff "stabil" in diesem Zusammenhang bedeuten soll. daß die wäßrigen Zusammensetzungen in einem Temperaturbereich von 0°C bis 40°C im wesentlichen keine Phasentrennung zeigen. d.h. Lösungen oder homogene Dispersionen darstellen.Surprisingly, in the proposed way in easier and more effective Way the problems mentioned above are avoided. It represents for the expert no difficulty in identifying those compounds in the overall composition, on the one hand taken together with water a stable composition On the other hand, allow the remaining ingredients of the overall composition also together with water give a stable composition. in which the term "stable" in this context. that the aqueous compositions in a temperature range of 0 ° C to 40 ° C substantially no phase separation demonstrate. i.e. Represent solutions or homogeneous dispersions.
Die Aufteilung der Inhaltsstoffe der Zusammensetzung in die wäßrigen Vormischungen hängt dabei selbstverständlich in starkem Maße von den Inhaltsstoffen der Gesamtzusammensetzung selbst ab. Da nicht in jedem Falle von vornherein eindeutig feststeht, welche Verbindungen oder Verbindungskombinationen dafür verantwortlich sind, daß die Gesamtzusammensetzung die erwünschte Phasentrennung durchläuft, wird im Einzelfalle erforderlich sein, die Zusammensetzung der Vormischung durch entsprechende Versuche zu ermitteln, wobei deren Durchführung aufgrund der Kenntnis der Wirkung der einzelnen Verbindungen in der Gesamtzusammensetzung und deren begrenzter Anzahl für den Fachmann ohne weiteres und insbesondere ohne eigene erfinderische Tätigkeit möglich ist.The distribution of the ingredients of the composition in the aqueous premixes depends of course, to a great extent, of the ingredients of the overall composition yourself off. Since it is not always clear from the start which connections or combinations of compounds are responsible for ensuring that the overall composition undergoes the desired phase separation, will be required in individual cases, to determine the composition of the premix by appropriate tests, wherein Their implementation is based on the knowledge of the effect of the individual compounds in the Total composition and its limited number for the skilled person readily and particular without their own inventive step is possible.
Bei einem alkalischen Produkt, wie es beispielsweise im nachfolgenden Beispiel 1 beschrieben ist, würde der Fachmann aufgrund der verwendeten Inhaltsstoffe insbesondere die hydrophoben Materialien oder diejenigen wasserlöslichen Verbindungen, die einen niedrigen Trübungspunkt haben, in die erste Vormischung herrübemehmen. Dies könnten beispielsweise der oder die Duftstoffe oder hydrophobe wasserunlösliche Lösemittel/Alkohole oder das oder die quartären Ammoniumsalze oder Tenside auf der Grundlage von Ethylenoxid und Propylenoxid, von denen bekannt ist, daß sie trotz Wasserlöslichkeit einen niedrigen Trübungspunkt haben, sein, um diese vom Rest der Formulierung, insbesondere vom Buildersystem (Chlorid, Carbonat, Phosphat) abzutrennen. In Beispiel 1 wurde konkret das quartäre Ammoniumsalz abgetrennt, was ausreichend war, um zwei stabile Vormischungen herzustellen.For an alkaline product, as described for example in Example 1 below is the expert would be particularly hydrophobic due to the ingredients used Materials or those water-soluble compounds that have a low cloud point have, take in the first premix. This could be, for example the perfume (s) or hydrophobic water-insoluble solvent (s) or alcohol or the quaternary ammonium salts or surfactants based on ethylene oxide and propylene oxide, which are known to have a low cloud point despite water solubility have to be that from the rest of the formulation, especially the builder system (Chloride, carbonate, phosphate) to separate. In Example 1, specifically, the quaternary ammonium salt which was sufficient to produce two stable premixes.
Bei einer sauren Zusammensetzung, wie sie beispielhaft in Beispiel 2 beschrieben ist. kann eine konkrete Lösung darin liegen, die Bildung von hydrophobem Material, das aus der Kombination von Sulfonat und quartärem Ammoniumsalz in der Gesamtzusammensetzung entsteht, zu vermeiden, indem man eine dieser beiden Substanzen bzw. Substanzgruppen in die erste Vormischung hinein abtrennt. Im konkreten Beispiel wurde hierfür das Sulfonat ausgewählt. Ebenso hätte man aber auch die beiden quartären Ammoniumsalze in die erste Vormischung hinein abtrennen und das Sulfonat in der zweiten Vormischung belassen können.In an acidic composition, as described by way of example in Example 2. can A concrete solution lies in the formation of hydrophobic material that is the combination of sulfonate and quaternary ammonium salt in the overall composition, To avoid by one of these two substances or groups of substances in the first premix is separated into it. In the concrete example, the sulfonate was selected for this purpose. But you would also have the two quaternary ammonium salts in the first premix remove it and leave the sulfonate in the second premix.
Aus der folgenden Tabelle ist die Zusammensetzung sowohl der ersten als auch der zweiten
Vormischung und die davon unterschiedliche Zusammensetzung der oberen und unteren Phase
des Endproduktes für eine alkalische Reinigungsmittelzusammensetzung ersichtlich. Bei
der Herstellung wurden die erste und die zweite Vormischung in einem Volumenverhältnis
von 20:80 eingesetzt. Die Vermischung der beiden Vormischungen erfolgte dadurch, daß zunächst
die erste Vormischung (die im vorliegenden Fall das geringere Volumen besitzt) und
anschließend die zweite Vormischung (mit dem größeren Volumen) in das Verpackungsbehältnis
eingefüllt wird, wobei eine entsprechende Durchmischung auftritt.

Claims (8)
- Method of preparing a liquid cleansing or detergent composition, filled and ready to use, which separates into at least two aqueous phases when left to stand, characterised in that at least two separate preliminary mixtures which do not exhibit any phase separation in the temperature range of from 0°C to 40°C are prepared, and these preliminary mixtures are not mixed with one another until or immediately before the packaging containers are filled.
- Method as claimed in claim 1, characterised in that the composition of each preliminary mixture is different from the composition of each of the aqueous phases which separate when the end product is left to stand.
- Method as claimed in claim 1 or 2, characterised in that a first preliminary mixture contains, in addition to the main ingredient, water, those substance(s) of the full composition which, if left out, essentially prevent separation into aqueous phases, whilst the remaining substances of the full composition are incorporated in a second preliminary mixture, also containing the main ingredient, water.
- Method as claimed in claim 3, characterised in that the first preliminary mixture contains a hydrophobic substance or a substance which forms a hydrophobic substance in conjunction with one or more other substances of the full composition.
- Method as claimed in claim 4, characterised in that the first preliminary mixture contains one or more fragrances, one or more hydrophobic water-insoluble solvents and/or, if both one or more quaternary ammonium salts and one or more sulphates are to be incorporated in the full composition, one of these two substance groups.
- Method as claimed in claim 3, characterised in that the first preliminary mixture contains one or more water-soluble substances with a low cloud point.
- Method as claimed in claim 6, characterised in that the first preliminary mixture contains one or more quaternary ammonium salts and/or one or more surfactants with a base of ethylene oxide and/or propylene oxide.
- Method as claimed in one of claims 3 to 7, characterised in that the first preliminary mixture and the second preliminary mixture are used in a ratio by volume of 5/95 to 50/50.
