Description

"Flüssiges Reinigungsmittel" "Liquid detergent"
Flüssige Reinigungsmittel bestehen meist aus wäßrigen Lösungen von syn¬ thetischen anionischen und/oder nichtionischen Tensiden und üblichen Zu¬ satzstoffen. Sie werden besonders zum Reinigen harter Oberflächen, zum Beispiel von Glas, keramischen Materialien, Kunststoffen, lackierten und polierten Oberflächen verwendet. Ein wichtiges Anwendungsgebiet für flüs¬ sige Reinigungsmittel ist das manuelle Spülen von Eß- und Kochgeschirr. Die Geschirreinigung wird üblicherweise bei leicht erhöhten Temperaturen von etwa 35 bis 45 °C in stark verdünnten Flotten durchgeführt. Dabei wird vom Verbraucher die Reinigungskraft eines Mittels im allgemeinen als umso besser beurteilt, je stärker und je länger die Reinigungsflotte schäumt. Wegen des Kontakts der Hände mit der Reinigungsflotte über einen längeren Zeitraum ist beim manuellen Spülen von Geschirr auch die Hautfreundlich¬ keit des Mittels von besonderer Bedeutung. Aus diesen Gründen stellt der Fachmann bei der Auswahl der Komponenten und der Zusammensetzung eines Mittels für das manuelle Reinigen von Geschirr andere Überlegungen an, als bei flüssigen Reinigungsmitteln für sonstige harte Oberflächen.Liquid cleaning agents usually consist of aqueous solutions of synthetic anionic and / or nonionic surfactants and customary additives. They are particularly used for cleaning hard surfaces, for example glass, ceramic materials, plastics, painted and polished surfaces. An important area of application for liquid cleaning agents is the manual washing of eating and cooking utensils. The dishes are usually cleaned in slightly diluted liquors at slightly elevated temperatures of around 35 to 45 ° C. In general, the cleaning power of an agent is judged by the consumer as the better, the stronger and the longer the cleaning liquor foams. Because the hands come into contact with the cleaning liquor over a longer period of time, the detergent's skin-friendliness is also of particular importance when washing dishes. For these reasons, the expert makes different considerations when selecting the components and the composition of an agent for the manual cleaning of dishes than with liquid detergents for other hard surfaces.
Die vorliegende Erfindung bezieht sich auf ein flüssiges, manuell anwend¬ bares, hautfreundliches Geschirreinigungsmittel mit starker Schaumentwick¬ lung und guter Reinigungskraft.The present invention relates to a liquid, manually applicable, skin-friendly dishwashing detergent with strong foaming and good cleaning power.
Es ist allgemein bekannt, daß sogenannte Alkylethersulfate, das heißt Sal¬ ze von sulfatierten Anlagerungsprodukten von etwa 2 bis 5 Mol Ethylenoxid an Fettalkohole mit etwa 8 bis 18, vorzugsweise etwa 12 bis 16 Kohlen¬ stoffatomen im aliphatischen Rest eine gute Schaum- und Reinigungskraft sowie hautfreundliche Eigenschaften besitzen. Die marktüblichen, manuell anwendbaren Geschirreinigungsmittel (alias Geschirrspülmittel) stellen daher im allgemeinen wäßrige Lösungen solcher Alkylethersulfate in Verbin¬ dung mit anderen Tensiden, insbesondere Alkylbenzolsulfonaten sowie Lö¬ sungsvermittlern, Färb- und Duftstoffen dar. Aus der schweizerischen Patentschrift 354 195 sind flüssige Reinigungs¬ mittel für das manuelle Geschirrspülen bekannt, die eine Kombination aus einem Alkylethersulfat und einem nichtionischen Tensid vom Typ des Fett- säurealkanola ids aus Mono- oder Dialkanolamiden mit nicht mehr als 3 Koh¬ lenstoffatomen in jedem Alkanolrest und gesättigten Fettsäuren mit 10 bis 14 Kohlenstoffatomen, zusammen mit Wasser, Lösungsvermittlern, Färb- und Duftstoffen enthalten.It is generally known that so-called alkyl ether sulfates, that is to say salts of sulfated adducts of about 2 to 5 moles of ethylene oxide with fatty alcohols having about 8 to 18, preferably about 12 to 16, carbon atoms in the aliphatic radical have good foaming and cleaning power and have skin-friendly properties. The commercially available, manual dishwashing detergents (also known as dishwashing detergents) are therefore generally aqueous solutions of such alkyl ether sulfates in conjunction with other surfactants, in particular alkylbenzenesulfonates and solubilizers, colorants and fragrances. From the Swiss patent 354 195 liquid cleaning agents for manual dishwashing are known, which are a combination of an alkyl ether sulfate and a nonionic surfactant of the fatty acid alkanol type consisting of mono- or dialkanolamides with no more than 3 carbon atoms in each alkanol residue and saturated fatty acids with 10 to 14 carbon atoms, together with water, solubilizers, colorants and fragrances.
Aus der europäischen Patentanmeldung 70 076 sind schäumende flüssige Rei¬ nigungsmittel mit einem Gehalt an Aniontensiden, Alkylglucosiden und Fett¬ säurealkanolamiden bekannt.European patent application 70 076 discloses foaming liquid cleaning agents containing anionic surfactants, alkyl glucosides and fatty acid alkanolamides.
Aus der deutschen Patentschrift 35 34 082 sind flüssige Reinigungsmittel für das manuelle Reinigen von Geschirr bekannt, die synthetische Anionten¬ side vom Typ der Sulfonat- und/oder Sulfattenside, Fettsäurealkanolamide und bestimmte Fettalkylglucoside enthalten.From the German patent specification 35 34 082 liquid detergents for the manual cleaning of dishes are known which contain synthetic anionic surfactants of the sulfonate and / or sulfate surfactant type, fatty acid alkanolamides and certain fatty alkyl glucosides.
Es wurde nun überraschenderweise gefunden, daß man die Schaum- und Reini¬ gungskraft flüssiger Reinigungsmittel, die speziell für das manuelle Rei¬ nigen von Geschirr konzipiert sind und die synthetische Aniontenside vom Typ der Sulfonat- und/oder Sulfattenside und nichtionische Tenside vom Typ der Fettsäurealkanolamide, Alkylpolyglykolether und/oder Fettalkyl¬ glycoside enthalten, dadurch verstärken kann, daß man als Fettsäurealka¬ nolamide oder zusätzlich zu bekannten Fettsäurealkanolamiden solche vom Typ der Fettsäureaminopropandiolamide einsetzt. Der Fettsäurerest weist etwa 8 bis 18, vorzugsweise etwa 10 bis 14 Kohlenstoffatome in der Alkyl- kette auf. Diese Verbindungen werden in einer Menge von etwa 1 bis 15, vorzugsweise von etwa 1 bis 5 Gewichtsprozent, bezogen auf das gesamte Mittel, eingesetzt.It has now surprisingly been found that the foaming and cleaning power of liquid cleaning agents which are specifically designed for manual cleaning of dishes and the synthetic anionic surfactants of the sulfonate and / or sulfate surfactant type and nonionic surfactants of the fatty acid alkanolamide type , Contain alkyl polyglycol ethers and / or fatty alkyl glycosides, which can be enhanced by using fatty acid aminopropanediol amides as fatty acid alkanolamides or in addition to known fatty acid alkanolamides. The fatty acid residue has about 8 to 18, preferably about 10 to 14 carbon atoms in the alkyl chain. These compounds are used in an amount of about 1 to 15, preferably about 1 to 5 percent by weight, based on the total agent.
Die Herstellung der Aminopropandiolamide geschieht durch Umsetzung von 1- oder 2-Aminopropandiol mit Fettsäuren oder Estern der Fettsäuren nach bekannten Verfahren, z.B. bevorzugt durch basisch katalysierte Umsetzung von Fettsäuremethylestern mit 1-Aminopropandiol bei Temperaturen zwischen etwa 110 und 180 °C unter Abdestiliieren des sich dabei abspaltenden Me¬ thanols. Löslichkeitsversuche zeigten, daß die hydrophileren Amide aus 1-Aminopro- pandiol besser wasserlöslich sind als die entsprechenden Derivate des Monoethanolamins, ein Effekt, der wegen der relativ schlechten Löslichkeit von bekannten Fettsäureamiden zu eindeutigen Vorteilen der besser lösli¬ chen Aminopropandiolamide führt.The aminopropanediolamides are prepared by reacting 1- or 2-aminopropanediol with fatty acids or esters of the fatty acids by known processes, for example preferably by base-catalyzed reaction of fatty acid methyl esters with 1-aminopropanediol at temperatures between about 110 and 180 ° C. while distilling off releasing methanol. Solubility tests showed that the more hydrophilic amides from 1-aminopropanediol are more soluble in water than the corresponding derivatives of monoethanolamine, an effect which leads to clear advantages of the more soluble aminopropanediolamides because of the relatively poor solubility of known fatty acid amides.
In einer bevorzugten Kombination werden als synthetische anionische Ten¬ side Alkylsulfate und/oder Alkylethersulfate eingesetzt. Damit werden vor¬ zugsweise keine anionischen Tenside, die eine petrochemische Basis haben, insbesondere kein Alkylbenzolsulfonat eingesetzt, die jedoch im übrigen im Sinne der Erfindung ebenfalls einsatzfähig sind. Die anionischen Tenside werden vorzugsweise als Natriumsalze eingesetzt. Die Natriumionen können bis zu etwa 50 % auch durch Magnesiumionen ersetzt werden, was die Haut¬ freundlichkeit steigert.In a preferred combination, alkyl sulfates and / or alkyl ether sulfates are used as synthetic anionic surfactants. In this way, preferably no anionic surfactants which have a petrochemical base, in particular no alkylbenzenesulfonate, are used, which, however, are also usable for the purposes of the invention. The anionic surfactants are preferably used as sodium salts. Up to about 50% of the sodium ions can also be replaced by magnesium ions, which increases the skin-friendliness.
Die eingesetzten Alkylsulfate beziehungsweise die entsprechenden Alkyl¬ ethersulfate sind handelsüblich, sie weisen einen aliphatischen C12-C18-, vorzugsweise Ci2-Ci4-Rest auf. Das zugehörige Kation ist vorzugsweise ein Alkali-, Erdalkali- oder Ammoniumion. Bei den Alkylethersulfaten liegt der Ethoxylierungsgrad bei etwa 1 bis 5, vorzugsweise bei etwa 2 bis 4. Ge¬ ringfügige zusätzliche Mengen an Alkylethersulfaten mit weniger als 12, beziehungsweise mehr als 14 Kohlenstoffatomen im Alkylrest verändern diese guten Ergebnisse nur unwesentlich, sollten jedoch vorzugsweise vermieden werden.The alkyl sulfates used or the corresponding alkyl ether sulfates are commercially available, they have an aliphatic C12-C18, preferably Ci2-Ci4 radical. The associated cation is preferably an alkali, alkaline earth or ammonium ion. In the case of the alkyl ether sulfates, the degree of ethoxylation is about 1 to 5, preferably about 2 to 4. Minor additional amounts of alkyl ether sulfates with less than 12 or more than 14 carbon atoms in the alkyl radical change these good results only insignificantly, but should preferably be avoided .
Die Einsatzmenge der Alkyl- und/oder Alkylethersulfate beträgt etwa 3 bis 40, vorzugsweise etwa 5 bis 20 Gewichtsprozent, bezogen auf das gesamte Mittel.The amount of alkyl and / or alkyl ether sulfates used is about 3 to 40, preferably about 5 to 20 percent by weight, based on the total agent.
Gegebenenfalls kann man zusätzlich noch bis zu etwa 10, vorzugsweise noch etwa 0,1 bis 5 Gew.-%, bezogen auf das gesamte Mittel, an bekannten Fett- säuremono- und/oder -dialkylolamiden oder Alkylpolyglykolethern mit etwa 8 bis 18, vorzugsweise etwa 8 bis 14 Kohlenstoffatomen im Alkylrest und etwa 1 bis 10, vorzugsweise etwa 2 bis 6 Mol Ethylenoxid im Molekül, die kon¬ ventionell verteilt oder eingeengt sein können (vergl. Seifen-Öle-Fette- Wachse, (1980), Uι6( 60 - 68), zusetzen. Die Menge der erfindungsgemäß einsetzbaren Cs-Ciö-Alkylglycoside mit etwa 1 - 2, vorzugsweise etwa 1 - 1,6 Glucoseeinheiten im Molekül kann etwa 0,1 bis 10, vorzugsweise etwa 1 bis 5 Gewichtsprozent, bezogen auf das gesamte Mittel, betragen.Optionally, up to about 10, preferably about 0.1 to 5% by weight, based on the total agent, of known fatty acid mono- and / or dialkylolamides or alkyl polyglycol ethers with about 8 to 18, preferably about 8 to 14 carbon atoms in the alkyl radical and about 1 to 10, preferably about 2 to 6, moles of ethylene oxide in the molecule, which can be conventionally distributed or concentrated (see. Seifen-Öle-Fette-Wwachs, (1980), Uι6 ( 60 - 68). The amount of the Cs-Ciö-alkylglycosides which can be used according to the invention with about 1-2, preferably about 1-1.6 glucose units in the molecule can be about 0.1 to 10, preferably about 1 to 5 percent by weight, based on the total agent.
Der Anteil aller nichtionischer Tenside im Geschirrspülmittel einschlie߬ lich der Aminopropandiolamide beträgt etwa 1 bis 20, vorzugsweise etwa 1,5 bis 15 Gew.-%, bezogen auf das gesamte Mittel, wobei das Gewichtsverhält¬ nis von Aminopropandiolamiden zu gegebenenfalls weiteren nichtionischen Tensiden etwa 1 : 3 bis 1 : 0,5, vorzugsweise etwa 1 : 1 beträgt.The proportion of all nonionic surfactants in the dishwashing detergent, including the aminopropanediol amides, is about 1 to 20, preferably about 1.5 to 15,% by weight, based on the total detergent, the weight ratio of aminopropanediol amides to optionally further nonionic surfactants being about 1 : 3 to 1: 0.5, preferably about 1: 1.
Als Lösungsvermittler, etwa für Farbstoffe und Parfümöle, können beispiels¬ weise sonstige Alkanola ine, Polyole, wie Ethylenglykol, Propylenglykol- 1,2 oder Glycerin und als Hydrotrope Alkali-alkylbenzolsulfonate mit 1 bis 3 Kohlenstoffatomen im Alkylrest, vorzugsweise Natriumcumolsulfonat, die¬ nen. Ihre Einsatzmengen liegen zwischen etwa 0 und 10 Gewichtsprozent, bezogen auf das gesamte Mittel.Other alkanols, polyols, such as ethylene glycol, propylene glycol 1,2 or glycerol, and as hydrotropes alkali alkylbenzenesulfonates having 1 to 3 carbon atoms in the alkyl radical, preferably sodium cumene sulfonate, can serve as solubilizers, for example for dyes and perfume oils, for example. The amounts used are between about 0 and 10 percent by weight, based on the total agent.
Zusätzlich können noch Lösungsmittel, wie niedermolekulare Alkanole mit 1 bis 4 Kohlenstoffatomen im Molekül, vorzugsweise Ethanol, n-Propanol und Isopropylalkohol eingesetzt werden. Ihre Einsatzmengen betragen dann eben¬ falls etwa 0 bis 10 Gewichtsprozent, bezogen auf das gesamte Mittel. Auch Verdickungsmittel wie Harnstoff oder Neutralsalze, auch Elektrolyte ge¬ nannte Salze, wie Natriumchlorid, Ammoniumchlorid und Magnesiumchlorid können einzeln oder kombiniert eingesetzt werden. Weitere übliche fakul¬ tative Zusätze sind Korrosionsinhibitoren, Konservierungsmittel, Farb¬ stoffe und Parfümöle.In addition, solvents such as low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably ethanol, n-propanol and isopropyl alcohol, can also be used. Their amounts then also amount to about 0 to 10 percent by weight, based on the total agent. Thickeners such as urea or neutral salts, and electrolytes, such as sodium chloride, ammonium chloride and magnesium chloride, can also be used individually or in combination. Further customary optional additives are corrosion inhibitors, preservatives, dyes and perfume oils.
Der auf insgesamt 100 Gewichtsprozent zu berechnende Rest für das Gesamt¬ mittel besteht jeweils aus Wasser.The remainder to be calculated for a total of 100 percent by weight for the total medium consists of water.
