Definitions
- Liquid detergent containing sulfo-oleic acid salts Liquid detergent containing sulfo-oleic acid salts
- DE 35 34 082 discloses liquid, manually usable, skin-friendly dishwashing detergents with strong foam development and good cleaning power, which use fatty alkyl sulfates or fatty alkyl ether sulfates as well as fatty acid alkanolamides and fatty alkyl monoglucosides with 10 to 18, preferably 12 to 14, carbon atoms in the fatty alkyl radical as synthetic anionic surfactants and contain solvents, hydrotropes, salts and the like. From DE 37 06 015.5 alkyl glucoside-containing, manually applicable liquid dishwashing detergents are also known, which contain a substantial proportion of di-n-alkyl sulfosuccinates. Finally, EP 70074 A2 also describes cleaning agents which contain combinations of alkyl polyglucosides and fatty alcohol sulfates or fatty alcohol ether sulfates.
- liquid cleaning agents For manually usable dishwashing detergents, a viscosity range from about 10 to about 1000 mPas, preferably from about 100 to about 400 mPas, has become established.
- Solutions of the cleaning-active substances in water are therefore usually added to solvents, such as low molecular weight mono- or dialcohols and / or hydrotropes, such as short-chain alkylbenzenesulfonates. to dilute them, or uses electrolytes, such as table salt, to raise the viscosity to low viscosity active substance solutions.
- solvents such as low molecular weight mono- or dialcohols and / or hydrotropes, such as short-chain alkylbenzenesulfonates.
- electrolytes such as table salt
- the present invention therefore relates to liquid, aqueous cleaning agents, in particular for the manual cleaning of dishes, based on synthetic anionic or mixtures of anionic and / or nonionic surfactants and, if appropriate, other conventional constituents, in particular solvents, hydrotropes and salts are characterized in that they contain sulfo-oleic disalts as hydrotropes. Their amount is preferably 15 to 40, in particular 20 to 35,% by weight, based on the content of other synthetic anionic surfactants.
- the sodium salts are preferred for reasons of economy.
- Cleaning agents based on fatty alkyl sulfates and / or fatty alkyl ether sulfates, fatty alkyl glucosides and fatty acid alkali are particularly preferred.
- Disulfonic acid disalts can be prepared by processes as described in GB 1 278421 or in DE 3926344.4. They have good network properties both in aqueous and in aqueous alkaline solution and are stable in hard water. In addition, these compounds have a very good solubility in water, are readily biodegradable and very kind to the skin. The degree of sulfonation can fluctuate within certain limits, which also slightly influences the hydrotope effect, but not in the clear tendency.
- sulfo oleic acid salts can lower the viscosity of solutions of anionic surfactants, since the saturated salts of the saturated Sulfofatty acid with the same number of carbon atoms, ⁇ -sulfostearic acid, is not able to do this. In contrast to the disalt of sulfo oleic acid, it is sparingly water-soluble. Only the shorter-chain ⁇ -sulfofatty acid disalts with 10 to 14 carbon atoms in the molecule are known as viscosity-reducing compounds for liquid or pasty detergent active substance concentrates (cf. DE 1 216470 and DE 1 221 391).
- Alkyl sulfates or alkyl ether sulfates are used as synthetic anionic surfactants.
- the invention creates a cleaning agent made from three different types of surfactants, the hydrophobic part of which is produced entirely from renewable raw materials (fats).
- the hydrophilic part of the molecule also consists of a renewable raw material (sugar).
- anionic surfactants which have a petrochemical base, in particular alkylbenzenesulfonate, are therefore not used. However, their viscosity in aqueous solution is also reduced according to the invention.
- the preferred alkyl sulfates or alkyl ether sulfates are commercially available, they have a straight-chain aliphatic C12-C18- 'preferably Cj2-Ci4 radical.
- the associated cation is preferably an alkali metal or ammonium ion.
- alkyl ether sulfates the degree of ethoxylation is 1 to 5; preferred is the use of an alkyl ethersulfatge Steam, consisting of 50 wt .-% of a C j 2- lkylethersulfats A and 50 wt .-% of a Ci4-alkyl ether sulfate having from 1 to 5, preferably 2 to 4 ethylene oxide instead of the conventionally used alkylether sulfate mixture, which contains the same components in a weight ratio of 70:30, is advantageous because it leads to a reduction in skin irritation without reducing the known good washing power of such agents.
- 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 be avoided if necessary.
- the amount of alkyl and / or alkyl ether sulfates used is 2 to 25, preferably 3 to 20 percent by weight, based on the total agent.
- the fatty acid alkanolamides used have an alkyl group with 8 to 18, preferably 10 to 14 carbon atoms in the fatty acid residue, while the amide group either with two hydroxyalkyl groups with 1 to 3 carbon atoms (dialkanolamide) or with such a hydroxyalkyl group and with hydrogen or a C-C3 ⁇ Alkyl group is substituted. These compounds are used in an amount of 1 to 15, preferably 1 to 5 percent by weight, based on the total agent. Mixtures of fatty acid mono- and dialkanolamides are preferably used.
- the fatty alkyl glucosides preferably used as nonionic surfactants are understood here to mean compounds with an average of less than two glucose units per fatty alkyl radical, in particular those with 1 to 1.4 glucose units.
- the fatty alkyl radical has 10 to 18, in particular essentially 12 to 14, carbon atoms.
- "Fatty alkyl” is understood to mean the residues of the fatty alcohols produced by hydrogenation of natural fatty acids, which are wholly or predominantly saturated, or which also comprise unsaturated portions.
- fatty alcohol ethoxylates having 10 to 18, preferably 12 to 14 carbon atoms in the fatty alkyl radical and 2 to 5, preferably 3 to 4, ethylene oxide groups in the molecule.
- the amount of the alkyl glucosides used according to the invention is 2 to 25, preferably 3 to 20% by weight, based on the total agent, this amount preferably being equal to or less than the combined amount of sulfate surfactant and fatty acid alkanolamide.
- the effect according to the invention also occurs when the surfactants mentioned are partially replaced by amphoteric surfactants such as.
- B. Acylamidopropyldimethylammo ⁇ iumbetain the performance increases in rinsing capacity and improvements in storage stability can cause. They can be present in the total product in amounts of 1 to 5, preferably 1.5 to 3% by weight. As the examples show, viscosities can be achieved according to the invention as desired for the finished product.
- small amounts of conventional solvents such as low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably ethanol and isopropyl alcohol, can of course also be used.
- the amounts used are about 3 to 5 percent by weight, based on the total agent, and are thus clearly below the amounts customary hitherto.
- Thickeners such as urea, sodium chloride, ammonium chloride and magnesium chloride can also be used individually or in combination.
- Other common optional additives are corrosion inhibitors, preservatives, dyes and perfume oils.
- Alkanolamines such as ethylene glycol, 1,2-propylene glycol or glycerol, for example, can serve as solubilizers, for example for dyes and perfume oils.
- the amounts used are between about 0.1 and 5 percent by weight, based on the total agent. The remainder to be calculated for a total of 100 percent by weight for the total composition consists of water.

Description
"Flüssioe Reinigungsmittel mit einem Gehalt an sulfoölsauren Disalzen""Liquid detergent containing sulfo-oleic acid salts"
Aus der DE 35 34 082 sind flüssige, manuell anwendbare hautfreundliche Geschirrspülmittel mit starker Schaumentwicklung und guter Reinigungskraft bekannt, die als synthetische anionische Tenside Fettalkylsulfate oder Fettalkylethersulfate sowie Fettsäurealkanolamide und Fettalkylmonogluco- side mit 10 bis 18, vorzugsweise 12 bis 14, Kohlenstoffatomen im Fettal- kylrest und Lösungsmittel, Hydrotrope, Salze und dergleichen enthalten. Aus der DE 37 06 015.5 sind ebenfalls alkylglucosidhaltige, manuell an¬ wendbare flüssige Geschirrspülmittel bekannt, die einen wesentlichen An¬ teil an Di-n-alkylsulfosuccinaten enthalten. Schließlich werden auch in der EP 70074 A2 Reinigungsmittel beschrieben, die Kombinationen aus Alkylpolyglucosiden und Fettalkoholsulfaten oder Fettalkoholethersulfaten enthalten.DE 35 34 082 discloses liquid, manually usable, skin-friendly dishwashing detergents with strong foam development and good cleaning power, which use fatty alkyl sulfates or fatty alkyl ether sulfates as well as fatty acid alkanolamides and fatty alkyl monoglucosides with 10 to 18, preferably 12 to 14, carbon atoms in the fatty alkyl radical as synthetic anionic surfactants and contain solvents, hydrotropes, salts and the like. From DE 37 06 015.5 alkyl glucoside-containing, manually applicable liquid dishwashing detergents are also known, which contain a substantial proportion of di-n-alkyl sulfosuccinates. Finally, EP 70074 A2 also describes cleaning agents which contain combinations of alkyl polyglucosides and fatty alcohol sulfates or fatty alcohol ether sulfates.
Häufig ist es nicht ausreichend, die Rohstoffe einfach zusammenzumischen, um zu verkaufsfähigen Produkten zu kommen, sondern es bedarf einer soge¬ nannten Konfektionierung, um die Mittel dem jeweiligen Geschmack des Rei¬ nigungsmittelmarktes anzupassen. Ein wesentlicher Gesichtspunkt bei flüs¬ sigen Reinigungsmitteln ist neben ihrer ausgelobten Wirkung daher auch ihr äußeres Erscheinungsbild. So dürfen flüssige Reinigungsmittel unabhängig von ihrem Gehalt an reinigungsaktiven Substanzen je nach Verwendungszweck nicht zu dünnflüssig sein, da die Hausfrau damit den Eindruck minderer Qualität verbindet, und sie dürfen nicht zu dickflüssig sein, damit sich die Mittel bei der Anwendung bequem handhaben, etwa dosieren 'lassen. Für manuell anwendbare Geschirrspülmittel hat sich ein Viskositätsbereich von etwa 10 bis etwa 1000 mPas, vorzugsweise von etwa 100 bis etwa 400 mPas, durchgesetzt. Man setzt den Lösungen der reinigungsaktiven Substanzen in Wasser daher üblicherweise Lösungsmittel, wie niedermolekulare Mono- oder Dialkohole und/oder Hydrotrope, wie kurzkettige Alkylbenzolsulfonate, zu,
um sie zu verdünnen oder verwendet Elektrolyte, wie etwa Kochsalz, um die Viskosität zu dünnflüssigen Aktivsubstanzlösungen anzuheben. Lösungsmittel sind dabei zum Teil relativ teuer und kurzkettige Alkylbenzolsulfonate haben selbst keinerlei Tensidcharakter.Often it is not sufficient to simply mix the raw materials together in order to arrive at salable products, but what is known as packaging is required in order to adapt the agents to the particular taste of the cleaning agent market. In addition to their advertised effect, an essential aspect of liquid cleaning agents is therefore also their external appearance. Thus, regardless of their content of cleaning-active substances, liquid cleaning agents must not be too thin, depending on the intended use, since the housewife associates them with the impression of inferior quality, and they must not be too thick, so that the agents are easy to use, e.g. to let. For manually usable dishwashing detergents, a viscosity range from about 10 to about 1000 mPas, preferably from about 100 to about 400 mPas, has become established. Solutions of the cleaning-active substances in water are therefore usually added to solvents, such as low molecular weight mono- or dialcohols and / or hydrotropes, such as short-chain alkylbenzenesulfonates. to dilute them, or uses electrolytes, such as table salt, to raise the viscosity to low viscosity active substance solutions. Solvents are sometimes relatively expensive and short-chain alkylbenzenesulfonates themselves have no surfactant character.
Es wurde nun gefunden, daß man die Viskosität von Tensiden oder Tensidge- ischen für Reinigungsmittel auf Basis von synthetischen anionischen und nichtionischen Tensiden oder deren Gemischen, insbesondere auf Basis von Fettalkylsulfaten und/oder Fettalkylethersulfaten, Alkylpolyglucosiden und Fettsäuremonoethanolamiden, durch Zugabe geringer Mengen an sulfoölsauren Disalzen, insbesondere den Dinatriumsalzen, ebenso oder besser reduzieren kann als durch Zusätze von Ethanol oder Hydrotropen.It has now been found that the viscosity of surfactants or surfactant disks for cleaning agents based on synthetic anionic and nonionic surfactants or mixtures thereof, in particular based on fatty alkyl sulfates and / or fatty alkyl ether sulfates, alkyl polyglucosides and fatty acid monoethanolamides, by adding small amounts of sulfo oleic acid salts , in particular the disodium salts, can be reduced equally or better than by adding ethanol or hydrotropes.
Die vorliegende Erfindung betrifft daher flüssige, wässrige Reinigungs¬ mittel, insbesondere für das manuelle Reinigen von Geschirr, auf Basis von synthetischen anionischen oder Gemischen aus anionischen und/oder nichtio¬ nischen Tensiden sowie gegebenenfalls sonstigen üblichen Bestandteilen, insbesondere Lösungsmitteln, Hydrotropen und Salzen, die dadurch gekenn¬ zeichnet sind, daß sie als Hydrotrope sulfoölsaure Disalze enthalten. Ihre Menge liegt vorzugsweise bei 15 bis 40, insbesondere 20 bis 35 Gew.-%, bezogen auf den Gehalt an sonstigen synthetischen anionischen Tensiden. Bevorzugt sind aus Gründen der Wirtschaftlichkeit die Natriumsalze. Be¬ sonders bevorzugt sind Reinigungsmittel auf Basis von Fettalkylsulfaten und/oder Fettalkylethersulfaten, Fettalkylglucosiden und Fettsäurealkano- la iden.The present invention therefore relates to liquid, aqueous cleaning agents, in particular for the manual cleaning of dishes, based on synthetic anionic or mixtures of anionic and / or nonionic surfactants and, if appropriate, other conventional constituents, in particular solvents, hydrotropes and salts are characterized in that they contain sulfo-oleic disalts as hydrotropes. Their amount is preferably 15 to 40, in particular 20 to 35,% by weight, based on the content of other synthetic anionic surfactants. The sodium salts are preferred for reasons of economy. Cleaning agents based on fatty alkyl sulfates and / or fatty alkyl ether sulfates, fatty alkyl glucosides and fatty acid alkali are particularly preferred.
Sulfoölsaure Disalze können nach Verfahren hergestellt werden, wie sie in der GB 1 278421 oder in der DE 3926344.4 beschrieben sind. Sie besitzen sowohl in wäßriger als auch in wäßriger alkalischer Lösung gute Netzei¬ genschaften und sind hartwasserstabil. Außerdem besitzen diese Verbin¬ dungen eine sehr gute Wasserlöslichkeit, sind leicht biologisch abbaubar und sehr hautfreundlich. Der Sulfierungsgrad kann in gewissen Grenzen schwanken, was auch die Hydrotopwirkung leicht beeinflußt, nicht jedoch in der deutl chen Tendenz.Disulfonic acid disalts can be prepared by processes as described in GB 1 278421 or in DE 3926344.4. They have good network properties both in aqueous and in aqueous alkaline solution and are stable in hard water. In addition, these compounds have a very good solubility in water, are readily biodegradable and very kind to the skin. The degree of sulfonation can fluctuate within certain limits, which also slightly influences the hydrotope effect, but not in the clear tendency.
Es war überraschend, daß sulfoölsaure Disalze die Viskosität von Lösungen anionischer Tenside zu senken vermögen, da das Disalz der gesättigten
Sulfofettsäure mit gleicher Kohlenstoffatomzahl, der α-Sulfostearinsäure, dazu nicht in der Lage ist. Es ist im Gegensatz zum Disalz der Sulfoöl¬ saure schwer wasserlöslich. Lediglich die kürzerkettigen α-sulfofettsauren Disalze mit 10 bis 14 Kohlenstoffatomen im Molekül sind als viskositäts- senkende Verbindungen für flüssige oder pastenförmige Waschaktivsubstanz¬ konzentrate bekannt (vgl. DE 1 216470 und DE 1 221 391).It was surprising that sulfo oleic acid salts can lower the viscosity of solutions of anionic surfactants, since the saturated salts of the saturated Sulfofatty acid with the same number of carbon atoms, α-sulfostearic acid, is not able to do this. In contrast to the disalt of sulfo oleic acid, it is sparingly water-soluble. Only the shorter-chain α-sulfofatty acid disalts with 10 to 14 carbon atoms in the molecule are known as viscosity-reducing compounds for liquid or pasty detergent active substance concentrates (cf. DE 1 216470 and DE 1 221 391).
Als synthetische anionische Tenside werden Alkylsulfate oder Alkylether¬ sulfate eingesetzt. In der Kombination dieser Sulfat-Tenside mit dem Fettsäurealkanolamid und dem Fettalkylglucosid schafft die Erfindung ein Reinigungsmittel aus drei verschiedenen Typen von Tensiden, deren hydro¬ phober Teil vollständig aus nachwachsenden Rohstoffen (Fetten) hergestellt wird. Im Falle der Alkylglucoside besteht auch der hydrophile Teil des Moleküls aus einem nachwachsenden Rohstoff (Zucker). In der bevorzugten Ausführungsform der Erfindung werden somit anionische Tenside, die eine petrochemische Basis haben, insbesondere Alkylbenzolsulfonat, nicht ein¬ gesetzt. Ihre Viskosität in wäßriger Lösung wird aber ebenfalls erfin¬ dungsgemäß reduziert.Alkyl sulfates or alkyl ether sulfates are used as synthetic anionic surfactants. In the combination of these sulfate surfactants with the fatty acid alkanolamide and the fatty alkyl glucoside, the invention creates a cleaning agent made from three different types of surfactants, the hydrophobic part of which is produced entirely from renewable raw materials (fats). In the case of alkyl glucosides, the hydrophilic part of the molecule also consists of a renewable raw material (sugar). In the preferred embodiment of the invention, anionic surfactants which have a petrochemical base, in particular alkylbenzenesulfonate, are therefore not used. However, their viscosity in aqueous solution is also reduced according to the invention.
Die bevorzugt eingesetzten Alkylsulfate beziehungsweise Alkylethersulfate sind handelsüblich, sie weisen einen geradkettigen aliphatischen C12-C18-' vorzugsweise Cj2-Ci4-Rest auf. Das zugehörige Kation ist vorzugsweise ein Alkalimetall- oder Ammoniuπrion. Bei den Alkylethersulfaten liegt der Ethoxylierungsgrad bei 1 bis 5; bevorzugt ist der Einsatz eines Alkyl- ethersulfatge isches, bestehend aus 50 Gew.-% eines Cj2-Alkylethersulfats und 50 Gew.-% eines Ci4-Alkylethersulfats mit 1 bis 5, vorzugsweise 2 bis 4 Ethylenoxidgruppen anstelle des üblicherweise eingesetzten Alkylether- sulfatgemisches, das die gleichen Komponenten im Gewichtsverhältnis 70 : 30 enthält, vorteilhaft, weil es zu einer Verminderung der Hautirritation führt, ohne die bekannt gute Waschkraft derartiger Mittel zu mindern. Ge¬ ringfügige zusätzliche Mengen an Alkylethersulfaten mit weniger als 12 beziehungsweise mehr als 14 Kohlenstoffato en im Alkylrest verändern diese guten Ergebnisse nur unwesentlich, sollten jedoch gegebenenfalls vermieden werden. Die Einsatzmenge der Alkyl- und/oder Alkylethersulfate beträgt 2
bis 25, vorzugsweise 3 bis 20 Gewichtsprozent, bezogen auf das gesamte Mittel.The preferred alkyl sulfates or alkyl ether sulfates are commercially available, they have a straight-chain aliphatic C12-C18- 'preferably Cj2-Ci4 radical. The associated cation is preferably an alkali metal or ammonium ion. In the case of alkyl ether sulfates, the degree of ethoxylation is 1 to 5; preferred is the use of an alkyl ethersulfatge Steam, consisting of 50 wt .-% of a C j 2- lkylethersulfats A and 50 wt .-% of a Ci4-alkyl ether sulfate having from 1 to 5, preferably 2 to 4 ethylene oxide instead of the conventionally used alkylether sulfate mixture, which contains the same components in a weight ratio of 70:30, is advantageous because it leads to a reduction in skin irritation without reducing the known good washing power of such agents. Slight 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 be avoided if necessary. The amount of alkyl and / or alkyl ether sulfates used is 2 to 25, preferably 3 to 20 percent by weight, based on the total agent.
Die eingesetzten Fettsäurealkanolamide weisen im Fettsäurerest eine Alkylgruppe mit 8 bis 18, vorzugsweise 10 bis 14 Kohlenstoffatomen auf, während die Amid-Gruppe entweder mit zwei Hydroxyalkylgruppen mit 1 bis 3 Kohlenstoffatomen (Dialkanolamid) oder mit einer solchen Hydroxyalkylgruppe und mit Wasserstoff oder einer Cι-C3~Alkylgruppe sub¬ stituiert ist. Diese Verbindungen werden in einer Menge von 1 bis 15, vorzugsweise von 1 bis 5 Gewichtsprozent, bezogen auf das gesamte Mittel, eingesetzt. Vorzugsweise kommen Gemische von Fettsäuremono- und - dialkanolamiden zum Einsatz.The fatty acid alkanolamides used have an alkyl group with 8 to 18, preferably 10 to 14 carbon atoms in the fatty acid residue, while the amide group either with two hydroxyalkyl groups with 1 to 3 carbon atoms (dialkanolamide) or with such a hydroxyalkyl group and with hydrogen or a C-C3 ~ Alkyl group is substituted. These compounds are used in an amount of 1 to 15, preferably 1 to 5 percent by weight, based on the total agent. Mixtures of fatty acid mono- and dialkanolamides are preferably used.
Unter den als nichtionische Tenside bevorzugt eingesetzten Fettalkylglu- cosiden werden hier Verbindungen mit durchschnittlich weniger als zwei Glucoseeinheiten pro Fettalkyl-Rest, insbesondere solche mit 1 bis 1,4 Glucoseeinheiten verstanden. Der Fettalkylrest weist 10 bis 18, insbeson¬ dere im wesentlichen 12 bis 14 Kohlenstoffatome auf. Unter "Fettalkyl" werden die Reste der durch Hydrierung von natürlichen Fettsäuren herge¬ stellten Fettalkohole, die ganz oder überwiegend gesättigt sind, oder die auch ungesättigte Anteile umfassen, verstanden. Außerdem kommen als nichtionische Tenside auch Fettalkoholethoxylate mit 10 bis 18, vorzugs¬ weise 12 bis 14 Kohlenstoffatomen im Fettalkylrest und 2 bis 5, vorzugs¬ weise 3 bis 4 Ethylenoxidgruppen im Molekül in Betracht.The fatty alkyl glucosides preferably used as nonionic surfactants are understood here to mean compounds with an average of less than two glucose units per fatty alkyl radical, in particular those with 1 to 1.4 glucose units. The fatty alkyl radical has 10 to 18, in particular essentially 12 to 14, carbon atoms. "Fatty alkyl" is understood to mean the residues of the fatty alcohols produced by hydrogenation of natural fatty acids, which are wholly or predominantly saturated, or which also comprise unsaturated portions. Also suitable as nonionic surfactants are fatty alcohol ethoxylates having 10 to 18, preferably 12 to 14 carbon atoms in the fatty alkyl radical and 2 to 5, preferably 3 to 4, ethylene oxide groups in the molecule.
Die Menge der erfindungsgemäß eingesetzten Alkylglucoside beträgt 2 bis 25, vorzugsweise 3 bis 20 Gew.-%, bezogen auf das gesamte Mittel, wobei diese Menge vorzugsweise gleich oder geringer ist, als die gemeinsame Menge aus Sulfat-Tensid und Fettsäurealkanolamid. Die erfindungsgemäße Wirkung tritt auch bei teilweisem Austausch der genannten Tenside durch Amphotenside wie z. B. Acylamidopropyldimethylammoπiumbetain, die Lei¬ stungssteigerungen im Spülvermögen und Verbesserungen der Lagerstabilität bewirken können, ein. Sie können in Mengen von 1 bis 5, vorzugsweise 1,5 bis 3 Gew.-% im Gesamtprodukt anwesend sein.
Wie die Beispiele zeigen, können erfindungsgemäß Viskositäten erreicht werden, wie sie für das fertige Produkt erwünscht sind. Für weitere Va¬ riationen können selbstverständlich noch geringe Mengen an üblichen Lö¬ sungsmitteln, wie niedermolekularen Alkanolen mit 1 bis 4 Kohlenstoff¬ atomen im Molekül, vorzugsweise Ethanol und Isopropylalkohol eingesetzt werden. Ihre Einsatzmengen betragen etwa 3 bis 5 Gewichtsprozent, bezogen auf das gesamte Mittel, und liegen damit deutlich unter den bisher übli¬ chen Mengen. Auch Verdickungsmittel wie Harnstoff, Natriumchlorid, Ammo¬ niumchlorid und Magnesiumchlorid können einzeln oder kombiniert eingesetzt werden. Weitere übliche fakultative Zusätze sind Korrosionsinhibitoren, Konservierungsmittel, Farbstoffe und Parfümöle.The amount of the alkyl glucosides used according to the invention is 2 to 25, preferably 3 to 20% by weight, based on the total agent, this amount preferably being equal to or less than the combined amount of sulfate surfactant and fatty acid alkanolamide. The effect according to the invention also occurs when the surfactants mentioned are partially replaced by amphoteric surfactants such as. B. Acylamidopropyldimethylammoπiumbetain, the performance increases in rinsing capacity and improvements in storage stability can cause. They can be present in the total product in amounts of 1 to 5, preferably 1.5 to 3% by weight. As the examples show, viscosities can be achieved according to the invention as desired for the finished product. For further variations, small amounts of conventional solvents, such as low molecular weight alkanols with 1 to 4 carbon atoms in the molecule, preferably ethanol and isopropyl alcohol, can of course also be used. The amounts used are about 3 to 5 percent by weight, based on the total agent, and are thus clearly below the amounts customary hitherto. Thickeners such as urea, sodium chloride, ammonium chloride and magnesium chloride can also be used individually or in combination. Other common optional additives are corrosion inhibitors, preservatives, dyes and perfume oils.
Als Lösungsvermittler, etwa für Farbstoffe und Parfümöle, können bei¬ spielsweise Alkanolamine, Polyole, wie Ethylenglykol, Propylenglykol-1,2 oder Glycerin dienen. Ihre Einsatzmengen liegen zwischen etwa 0,1 und 5 Gewichtsprozent, bezogen auf das gesamte Mittel. Der auf insgesamt 100 Gewichtsprozent zu berechnende Rest für das Gesamtmittel besteht jeweils aus Wasser.Alkanolamines, polyols, such as ethylene glycol, 1,2-propylene glycol or glycerol, for example, can serve as solubilizers, for example for dyes and perfume oils. The amounts used are between about 0.1 and 5 percent by weight, based on the total agent. The remainder to be calculated for a total of 100 percent by weight for the total composition consists of water.
Die erfindungsgemäßen flüssigen Reinigungsmittel nach den folgenden Bei¬ spielen wurden durch Zusammenrühren der einzelnen Bestandteile und Ste¬ henlassen des Gemisches bis zur Blasenfreiheit erhalten. Als anionische Tenside wurden in den Beispielen jeweils die Natriumsalze eingesetzt.The liquid cleaning agents according to the invention according to the following examples were obtained by stirring the individual components together and leaving the mixture to stand until there were no bubbles.

Wie den Beispielen zu entnehmen ist, verringert das sulfoölsaure Dinatriumsalz die Viskosität der Tensidkonzentrate bei Einsatz geringerer Mengen als an Ethanol erforderlich wäre (vgl. Beispiel 4 und 5 sowie 9 und 10). α-sulfostearinsaure Dinatriumsalze erhöhen die Viskosität dagegen (vgl. Beispiele 2 und 6 sowie 14 und 15 bzw. 17 und 18).
As can be seen from the examples, the sulfo-oleic disodium salt reduces the viscosity of the surfactant concentrates when using smaller amounts than would be required for ethanol (cf. Examples 4 and 5 and 9 and 10). In contrast, disulphate salts of α-sulfostearic acid increase the viscosity (cf. Examples 2 and 6 and 14 and 15 or 17 and 18).
