Derartige wäßrige Flüssigreiniger liegen überlicherweise als homogene stabile Lösungen oder Dispersionen vor. Der Einsatz bestimmter, insbesondere hydrophober, Komponenten in solchen Reinigungsmitteln kann jedoch dazu führen, daß diese Homogenität verloren geht und inhomogene Mittel erhalten werden, deren Akzeptanz beim Verbraucher als gering einzuschätzen ist. In solchen Fällen bedarf es der alternativen Formulierung von Mitteln, die trotz ihrer Inhomogenität eine definierte und für den Verbraucher akzeptable äußere Erscheinungs- und Anwendungsform aufweisen. Such aqueous liquid cleaners are usually homogeneous stable solutions or dispersions. The use of certain especially hydrophobic, components in such cleaning agents can, however, result in this homogeneity being lost goes and inhomogeneous means are obtained, their acceptance can be assessed as low by the consumer. In such cases an alternative formulation of means is required, despite their inhomogeneity a defined and acceptable for the consumer have external appearance and application form.

(p = 0, e = 7) sowie deren Mischungen.
Es können auch endgruppenverschlossene C8-C18-Alkylalkoholpolyglykolether
eingesetzt werden, d.h. Verbindungen in denen die freie
OH-Gruppe in der Formel II verethert ist. Die endgruppenverschlossenen
C8-C18-Alkylalkoholpolyglykolether können nach einschlägigen
Methoden der präparativen organischen Chemie erhalten
werden. Vorzugsweise werden C8-C18-Alkylalkohopolyglykolether in
Gegenwart von Basen mit Alkylhalogeniden, insbesondere Butyloder

The C 8 -C 18 alkyl alcohol polyglycol ethers of the formula II can be obtained by addition of propylene oxide and / or ethylene oxide to alkyl alcohols, preferably to fatty alcohols. Typical examples are polyglycol ethers of the formula II in which R 1 is an alkyl radical having 8 to 18 carbon atoms, p is 0 to 2 and e is a number from 2 to 7.

C 8 -C 18 -Alkyl alcohol polyglycol ethers are preferably reacted with alkyl halides, in particular butyl or benzyl chloride, in the presence of bases. Typical examples are mixed ethers of the formula II in which R 1 is an industrial fatty alcohol radical, preferably C 12/14 cocoalkyl radical, p is 0 and e is 5 to 10, which are sealed with a butyl group.
Bevorzugte nichtionische Tenside sind weiterhin Alkylpolyglykoside
(APG) der Formel III, R2O[G]x, in der R2 für einen linearen
oder verzweigten, gesättigten oder ungesättigten Alkylrest mit 8
bis 22 Kohlenstoffatomen, [G] für einen glykosidisch verknüpften
Zuckerrest und x für eine Zahl von 1 bis 10 stehen. APG sind
nichtionische Tenside und stellen bekannte Stoffe dar, die nach
den einschlägigen Verfahren der präparativen organischen Chemie
erhalten werden können. Die Indexzahl x in der allgemeinen Formel
III gibt den Oligomerisierungsgrad (DP-Grad) an, d.h. die
Verteilung von Mono- und Oligoglykosiden, und steht für eine Zahl
zwischen 1 und 10. Während x in einer gegebenen Verbindung stets
ganzzahlig sein muß und hier vor allem die Werte x = 1 bis 6 annehmen
kann, ist der Wert x für ein bestimmtes Alkylglykosid eine
analytisch ermittelte rechnerische Größe, die meistens eine gebrochene
Zahl darstellt. Vorzugsweise werden Alkylglykoside mit
einem mittleren Oligomerisierungsgrad x von 1,1 bis 3,0 eingesetzt.
Aus anwendungstechnischer Sicht sind solche Alkylglykoside
bevorzugt, deren Oligomerisierungsgrad kleiner als 1,7 ist und
insbesondere zwischen 1,2 und 1,6 liegt. Als glykosidische Zucker
wird vorzugsweise Xylose, insbesondere aber Glucose verwendet.
Der Alkyl- bzw. Alkenylrest R2 (Formel III) kann sich von primären
Alkoholen mit 8 bis 18, vorzugsweise 8 bis 14 Kohlenstoffatomen
ableiten. Typische Beispiele sind Capronalkohol, Caprylalkohol,
Caprinalkohol und Undecylalkohol sowie deren technische Gemische,
wie sie beispielsweise im Verlauf der Hydrierung von technischen
Fettsäuremethylestern oder im Verlauf der Hydrierung von Aldehyden
aus der ROELENschen Oxosynthese anfallen.
Vorzugsweise leitet sich der Alkyl- bzw. Alkenylrest R2 aber von
Laurylalkohol, Myristylalkohol, Cetylalkohol, Palmoleylalkohol,
Stearylalkohol, Isostearylalkohol oder Oleylalkohol ab. Weiterhin
sind Elaidylalkohol, Petroselinylalkohol, Arachidylalkohol, Gadoleylalkohol,
Behenylalkohol, Erucylalkohol sowie deren technische
Gemische zu nennen.Preferred nonionic surfactants are furthermore alkyl polyglycosides (APG) of the formula III, R 2 O [G] x , in which R 2 is a linear or branched, saturated or unsaturated alkyl radical having 8 to 22 carbon atoms, [G] is a glycosidically linked sugar radical and x stands for a number from 1 to 10. APG are non-ionic surfactants and are known substances that can be obtained using the relevant methods of preparative organic chemistry. The index number x in the general formula III indicates the degree of oligomerization (DP degree), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While x must always be an integer in a given compound and here before can assume all the values x = 1 to 6, the value x for a certain alkyl glycoside is an analytically determined arithmetic parameter, which usually represents a fractional number. Alkyl glycosides with an average degree of oligomerization x of 1.1 to 3.0 are preferably used. From an application point of view, those alkyl glycosides are preferred whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.6. Xylose, but especially glucose, is preferably used as the glycosidic sugar.
The alkyl or alkenyl radical R 2 (formula III) can be derived from primary alcohols having 8 to 18, preferably 8 to 14, carbon atoms. Typical examples are capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as those obtained in the course of the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from ROELEN's oxosynthesis.
However, the alkyl or alkenyl radical R 2 is preferably derived from lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol or oleyl alcohol. Elaidyl alcohol, petroselinyl alcohol, arachidyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and their technical mixtures are also to be mentioned.

Zur Prüfung des Reinigungsvermögens der erfindungsgemäß formulierten Reinigerzusammensetzungen diente die unten nach SeifenÖle-Fette-Wachse 1986, 112, S. 371, beschriebene Testmethode, die sehr gut reproduzierbare Ergebnisse liefert. Danach wurde das zu prüfende Reinigungsmittel auf eine künstlich angeschmutzte weiße Kunststoffoberfläche gegeben. Als künstliche Anschmutzung für die verdünnte Anwendung des Reinigungsmittels wurde ein Gemisch aus Ruß, Maschinenöl, Triglycerid aus gesättigten Fettsäuren und niedersiedendem aliphatischen Kohlenwasserstoff verwendet. Die Testfläche von 26 x 28 cm wurde mit Hilfe eines Flächenstreichers gleichmäßig mit 2 g der künstlichen Anschmutzung beschichtet.The test method described below according to SeifenÖle-Fette-Wwachs 1986 , 112 , p. 371, which provides very reproducible results, was used to test the cleaning ability of the detergent compositions formulated according to the invention . The cleaning agent to be tested was then placed on an artificially soiled white plastic surface. A mixture of carbon black, machine oil, triglyceride of saturated fatty acids and low-boiling aliphatic hydrocarbon was used as artificial soiling for the dilute use of the cleaning agent. The test area of 26 x 28 cm was evenly coated with 2 g of the artificial soiling with the aid of a surface coater.
Ein Kunststoffschwamm wurde jeweils mit 10 ml der zu prüfenden Reinigungsmittellösung getränkt und mechanisch auf der ebenfalls mit 10 ml der zu prüfenden Reinigungsmittel beschichteten Testfläche bewegt. Nach 10 Wischbewegungen wurde die gereinigte Testfläche unter fließendes Wasser gehalten und der lose sitzende Schmutz entfernt. Die Reinigungswirkung, d.h. der Weißgrad der sogenannten Kunststoffoberfläche wurde mit einem Farb-Differenz-Meßgerät "Microcolor" (Dr. Lange) gemessen. Als Weiß-Standard diente die saubere unbehandelte weiße Kunststoffoberfläche.A plastic sponge was each with 10 ml of the test Detergent solution soaked and mechanically on the same test area coated with 10 ml of the cleaning agent to be tested emotional. After 10 wiping movements, the cleaned test area held under running water and the loose one Dirt removed. The cleaning effect, i.e. the whiteness of the So-called plastic surface was made with a color difference measuring device "Microcolor" (Dr. Lange) measured. As a white standard served the clean untreated white plastic surface.
Der Test wurde mit dem erfindungsgemäßen Reinigungsmittel E1 in verdünnter Anwendung mit einer Konzentration von 6 ml·l-1 und in unverdünnter Anwendung durchgeführt.
