A liquid cleaner based on an aqueous solution of anionic surfactants, optionally in conjunction with nonionic surfactants, solvents, solution promoters, corrosion inhibitors, preservatives, thickeners and also dyes and fragrances, characterized in that it contains from 2 to 40 % by weight of a 50:50 (parts by weight) mixture of a sulfated adduct of 1 to 5 moles of ethylene oxide with an n-C12 -alkanol and with an n-C14 -alkanol and, optionally, up to 20 % by weight of a surface-active betaine.

Description

Flüssige Wasch-, Spül- und Reinigungsmittel stellen meist wäßrige Lösungen von anionischen und/oder nichtionischen Tensiden und üblichen Zusatzstoffen dar. Sie werden zum Waschen von Textilien, zum Reinigen harter Oberflächen, zum Beispiel von Gläsern oder keramischen Materialien, von Kunststoffen, lackierten und. polierten Oberflächen, die auch metallischer Natur sein können, vewendet. Ein bevorzugtes Anwendungsgebiet derartiger Mittel ist das manuelle Spülen von Eßgeschirr und anderen damit verwandten Gerätschaften. Die jeweiligen Reinigungsvorgänge werden üblicherweise bei leicht erhöhten Temperaturen durchgeführt. Dabei findet stets eine verstärkte Einwirkung auf die menschliche Haut statt.Liquid washing, rinsing and cleaning agents are usually aqueous solutions of anionic and / or nonionic surfactants and customary additives. They are used for washing textiles, for cleaning hard surfaces, for example glasses or ceramic materials, plastics, lacquered and. polished surfaces, which can also be metallic in nature, are used. A preferred area of application for such agents is the manual washing of dining utensils and other related equipment. The respective cleaning processes are usually carried out at slightly elevated temperatures. There is always an increased impact on human skin.

Die vorliegende Erfindung betrifft daher Reinigungsmittel mit verbesserter Hautschutzwirkung und starker Waschkraft.The present invention therefore relates to cleaning agents with improved skin protection and strong washing power.

Es ist bekannt, daß sogenannte Alkylethersulfate, das heißt sulfatierte Anlagerungsprodukte von etwa 2 bis 5 Mol Ethylenoxid an Fettalkohole mit etwa 10 bis 16 Kohlenstoffatomen im Alkylrest eine gute Waschkraft bei gleichzeitiger milder Wirkung auf die Haut besitzen. Die marktüblichen, manuell anzuwendenden Geschirrspülmittel stellen daher wäßrige Lösungen solcher Alkylethersulfate in Verbindung mit anderen anionischen Tensiden wie n-Alkylbenzolsulfonaten und/oder Alkansulfonaten, gegebenenfalls auch Olefinsulfonaten oder Alkylsulfaten sowie-nichtionischen Tensiden, Lösungsvermittlern, Farb- und Duftstoffen dar.It is known that so-called alkyl ether sulfates, that is to say sulfated adducts of about 2 to 5 moles of ethylene oxide with fatty alcohols with about 10 to 16 carbon atoms in the alkyl radical, have good washing power and at the same time have a mild effect on the skin. The commercially available dishwashing agents which are to be used manually are therefore aqueous solutions of such alkyl ether sulfates in combination with other anionic surfactants such as n-alkylbenzenesulfonates and / or alkanesulfonates, optionally also olefin sulfonates or alkyl sulfates and nonionic surfactants, solubilizers, colorants and fragrances.

Es wurde nun überraschend gefunden, daß der Einsatz eines Alkylethersulfatgemisches, bestehend aus 50 Gewichtsprozent eines C12-Alkylethersulfats und 50 Gewichtsprozent eines C,4-Alkylether- sulfats mit 1 bis 5, vorzugsweise 2 bis 4 Ethylenoxidgruppen als Etherkomponente gegenüber dem üblicherweise eingesetzten Alkylethersulfatgemisch, das die gleichen Komponenten im Gewichtsverhältnis 70 : 30 enthält, zu einer unerwarteten weiteren Verminderung der Hautirritätion führt, ohne die bekannt gute Waschkraft derartiger Mittel zu mindern. Geringfügige zusätzliche Mengen an Alkylethersulfaten mit mehr oder weniger als 12 beziehungsweise 14 Kohlenstoffatomen im Alkylrest verändern diese guten Ergebnisse nur unwesentlich, sollten jedoch möglichst vermieden werden.It has now surprisingly been found that the use of an alkyl ether sulfate mixture consisting of 50 percent by weight of a C 12 alkyl ether sulfate and 50 percent by weight of a C 4 alkyl ether sulfate with 1 to 5, preferably 2 to 4, ethylene oxide groups as ether component compared to the alkyl ether sulfate mixture normally used, that contains the same components in a weight ratio of 70:30 leads to an unexpected further reduction in skin irritation without reducing the known good washing power of such agents. Small additional amounts of alkyl ether sulfates with more or less than 12 or 14 carbon atoms in the alkyl radical change these good results only insignificantly, but should be avoided if possible.

Es ist weiterhin bekannt, daß amphotere oberflächenaktive Mittel vom Betaintyp eine milde Wirkung auf die Haut ausüben. Daher wurde erwartet, daß eine Kombination der erfindungsgemäß eingesetzten Mischung aus C12/C14-Alkylethersulfaten mit Betainen eine zusätzliche Steigerung der Hautverträglichkeit zeigen würde. Diese erwartete Wirkung konnte jedoch nicht ermittelt werden. Um so überraschender war jedoch, daß durch weiteren Zusatz derartiger Betaine eine signifikante Steigerung der Waschwirksamkeit erzielt werden konnte.It is also known that betaine-type amphoteric surfactants have a mild effect on the skin. It was therefore expected that a combination of the mixture of C 12 / C 14 alkyl ether sulfates and betaines used according to the invention would show an additional increase in skin tolerance. However, this expected effect could not be determined. It was all the more surprising, however, that a significant increase in washing effectiveness could be achieved by further addition of such betaines.

Gegenstand der vorliegenden Erfindung ist daher ein flüssiges Reinigungsmittel auf Basis einer wäßrigen Lösung von anionischen Tensiden, gegebenenfalls zusammen mit nichtionischen Tensiden, Lösungsmitteln, Lösungsvermittlern, Korrosionsinhibitoren, Konservierungsmitteln, Verdickungsmitteln sowie Farb- und Duftstoffen, das dadurch gekennzeichnet ist, daß es 2 bis 40 Gewichtsprozent eines Gemisches aus je 50 Gewichtsteilen eines sulfatierten Anlagerungsproduktes von 1 bis 5 Ethylenoxid an ein n-C12-Alkanol und an ein n-C14-Alkanol und gegebenenfalls bis zu 20 Gewichtsprozent eines oberflächenaktiven Betains enthält.The present invention therefore relates to a liquid cleaning agent based on an aqueous solution of anionic surfactants, optionally together with nonionic surfactants, solvents, solubilizers, corrosion inhibitors, preservatives, thickeners and colorants and fragrances, which is characterized in that it is 2 to 40 percent by weight a mixture of 50 parts by weight of a sulfated adduct of 1 to 5 ethylene oxide with an nC 12 alkanol and with an nC 14 alkanol and optionally up to 20 percent by weight of a surface-active betaine.

Eine bevorzugte Ausführungsform des erfindungsgemäßen flüssigen Reinigungsmittels ist dadurch gekennzeichnet, daß es 4 bis 20 Gewichtsprozent eines Gemisches aus je 50 Gewichtsteilen eines sulfatierten Anlagerungsproduktes von 2 bis 4 Mol Ethylenoxid an ein n-C12-Alkanol und an ein n-C14-Alkanol und gegebenenfalls 2 bis 5 Gewichtsprozent eines oberflächenaktiven Betains enthält.A preferred embodiment of the liquid cleaning agent according to the invention is characterized in that it contains 4 to 20 percent by weight of a mixture of 50 parts by weight of a sulfated adduct of 2 to 4 moles of ethylene oxide with an nC 12 alkanol and with an nC 14 alkanol and optionally 2 to 5 Contains percent by weight of a surfactant betaine.

Die Beispiele 1 bis 6 wurden für Vergleichsversuche herangezogen. Dabei wurde bei den Beispielen 1 bis 3 das erfindungsgemäße Sulfatgemisch jeweils mengengleich durch ein 70 : 30-C12-/C14-Alkyl-(EO)2-sulfatgemisch ersetzt. Bei den Beispielen 4 bis 6 wurde das Betain weggelassen und die Tensidanteile verhältnisgleich erhöht. Die Vergleichsprodukte entsprechen handelsüblichen Reinigungsmitteln. In allen Fällen wurde die Hautirritation nach dem Seifen-Kammer-Test (vgl. »Journal of the American Academy of Dermatology« 1 [1979], Seiten 35 bis 41) bestimmt.Examples 1 to 6 were used for comparative experiments. In Examples 1 to 3, the sulfate mixture according to the invention was replaced in each case in equal quantities by a 70:30 C 12 - / C 14 alkyl (EO) 2 sulfate mixture. In Examples 4 to 6, the betaine was omitted and the surfactant proportions increased proportionately. The comparison products correspond to commercially available cleaning agents. In all cases, skin irritation was determined according to the soap-chamber test (cf. "Journal of the American Academy of Dermatology" 1 [1979], pages 35 to 41).

Außerdem wurde der sognannte Tellertest durchgeführt. Die Methodik ist in der Zeitschrift »Fette; Seifen; Anstrichmittel«, 74 [1972], Seiten 163 bis 165 beschrieben. Es wurde vorwiegend mit Wasser von 45°C/16°d und einem Einsatz von 0,5 g/I Produkt sowie einer Mischanschmutzung aus Eiweiß, Fett und Kohlehydraten gearbeitet. Die Mischanschmutzung wurde mit 2 g/Teller (Untertasse von 14 cm Durchmesser; verteilt in der Tassenvertiefung) eingesetzt; die angeschmutzten Teller wurden nach 15 Stunden Lagerung bei ±0 bis +5°C unter den oben angegebenen Bedingungen gespült.The so-called plate test was also carried out. The methodology is in the magazine »Fette; Soap; Anstrichmittel «, 74 [1972], pages 163 to 165.
