Description

Gebiet der ErfindungField of the Invention
Die Erfindung betrifft neue wäßrige Bleich- und Desinfektionsmittel, enthaltend Hypochlonte, Ethercarboxylate und Hydroxide in definierten MengenverhältnissenThe invention relates to new aqueous bleaching and disinfecting agents containing hypochlones, ether carboxylates and hydroxides in defined proportions
Stand der TechnikState of the art
In der Vergangenheit haben sich in den Bereichen Hygiene und Desinfektion, aber auch in der Textilbehandlung, solche Bleichmittel auf der Grundlage von Alkalimetallhypochloπten bewahrt, die über eine bemerkenswerte Viskosität verfugen und sich daher sowohl für die Behandlung horizontaler als auch geneigter und vor allem vertikaler Oberflachen eignen Die Viskosität dieser Mittel bewirkt, daß die Kontaktzeit zwischen diesen und den zu behandelnden Oberflachen wesentlich großer ist als bei handelsüblichen Flussigprodukten, die rasch von der Oberflache abfließenIn the past, in the areas of hygiene and disinfection, but also in textile treatment, such bleaches based on alkali metal hypochlorites have been found to have a remarkable viscosity and are therefore suitable for the treatment of horizontal as well as inclined and, above all, vertical surfaces The viscosity of these agents has the effect that the contact time between them and the surfaces to be treated is considerably longer than with commercially available liquid products which drain off quickly from the surface
Aus einer Vielzahl von Schπften sind derartig viskose Bleich- und Desinfektionsmittel bekannt Beispielhaft seien hier einige Patente zu diesem Thema genanntSuch viscous bleaching agents and disinfectants are known from a large number of branches. Some patents on this subject are mentioned here as examples
In der EP 0 274 885 A (IG) wird beispielsweise der Einsatz von Mischungen linearer und verzweigter Aminoxide empfohlen Gegenstand der EP 0 340 371 A (Henkel Ibeπca) sind Bleichmittel auf Basis von wäßrigen Hypochloπtlosungen, die als Tensidkomponente überwiegend Alkylethersulfate und daneben kleine Anteile an Aminoxiden enthalten. Im Deutschen Patent DE 43 33 100 C1 hat die Anmelderin bereits stabile und ausreichend viskose wäßrige Bleich- und Reinigungsmittel auf Basis von Hypochlonten, Fettalkoholethersulfaten und Aminoxiden vorgeschlagen, die als zwingende Komponente Aminoxidphosphonsauren enthalten, die entscheidend zur Verdickung der Mittel beitragen Die EP 0 812 908 A offenbart Reinigungsmittel, die Alkalimetallhypochlont, ein hypochloπtkompatibles Tensid, z B ein Alkylethercarboxylat, und zur Verringerung der Schaumbildung ein endgruppenverschlossenes alkoxyliertes nichtionisches Tensid enthalten Aus der NL 9401510 sind wäßrige Bleichmittel mit erhöhter Viskosität bekannt, die ein Alkalimetallhypochlont, eine Tensidzusammensetzung aus einer Alkylethercarbonsaure oder deren Salz, einer Fettsäure oder deren Salz und einem Alkylethersulfat und/oder einem Alkylsulfobetain und ein Alkalimetallhydroxid enthalten, wobei die Alkylethercarbonsaure oder deren Salz bis zu 75 Gew.-% der Tensidzusammensetzung ausmacht. In der praktischen Anwendung weisen die aus der Literatur bekannten Hypochloritlaugen häufig für die Reinigung harter Oberflächen eine zu hohe Viskosität auf (Viskositäten > 130 mPas gemessen im Brookfield-Viskosimeter bei 20 °C, Spindel 1 , 60 Upm). Darüber hinaus wird vielfach die zu starke Schaumentwicklung (Schaumhöhen > 100 ml gemessen im Ross-Miles Test bei 20 °C) als störend angesehen. Im Vergleich zu den bisherigen Produkten wären ebenso preisgünstigere Bleich- und Desinfektionsmittel wünschenswert.EP 0 274 885 A (IG), for example, recommends the use of mixtures of linear and branched amine oxides. EP 0 340 371 A (Henkel Ibeπca) relates to bleaching agents based on aqueous hypochlorite solutions, the surfactant component being predominantly alkyl ether sulfates and small proportions Contain amine oxides. In German patent DE 43 33 100 C1, the applicant has already proposed stable and sufficiently viscous aqueous bleaching and cleaning agents based on hypochlones, fatty alcohol ether sulfates and amine oxides, which contain, as a mandatory component, amine oxide phosphonic acids, which make a decisive contribution to the thickening of the agents. EP 0 812 908 A discloses cleaning agents which contain alkali metal hypochlone, a hypochlorite-compatible surfactant, for example an alkyl ether carboxylate, and, to reduce foam formation, contain an end-capped alkoxylated nonionic surfactant. From NL 9401510, aqueous bleaches with increased viscosity are known which comprise an alkali metal hypochlorite from an alkyl ether carboxylate, a surfactant composition or their salt, a fatty acid or their salt and an alkyl ether sulfate and / or an alkyl sulfobetaine and an alkali metal hydroxide, the alkyl ether carboxylic acid or its salt making up up to 75% by weight of the surfactant composition. In practical use, the hypochlorite liquors known from the literature often have too high a viscosity for cleaning hard surfaces (viscosities> 130 mPas measured in a Brookfield viscometer at 20 ° C, spindle 1, 60 rpm). In addition, the excessive foam development (foam heights> 100 ml measured in the Ross-Miles test at 20 ° C) is often regarded as disturbing. In comparison to previous products, less expensive bleach and disinfectants would also be desirable.
Die Aufgabe der Erfindung hat somit darin bestanden, neue wäßrige Bleich- und Desinfektionsmittel zur Verfügung zu stellen, die sich durch eine geringere Schaumentwicklung als die bisher erhältlichen Mittel auszeichnen und weniger viskos als diese sind.The object of the invention was therefore to provide new aqueous bleaching and disinfecting agents which are characterized by less foaming than the agents available hitherto and are less viscous than these.

Die Herstellung der erfindungsgemäßen Mittel erfolgt mittels Umrühren. Gegebenenfalls kann das erhaltene Produkt zur Abtrennung von Fremdkörpern und/oder Agglomeraten dekantiert oder filtriert werden. Die Mittel weisen zudem unmittelbar nach der Herstellung eine Viskosität - gemessen bei 20 °C mit einem Brookfield-Viskosimeter (Modell RVT, Spindel 1 , 60 Upm) - unterhalb von 130, vorzugsweise unterhalb von 100, insbesondere unterhalb von 50 mPas und eine Schaumhöhe unterhalb von 100, vorzugsweise unterhalb von 80, insbesondere von nicht mehr als 60 ml - gemessen bei 20 °C in einem Ross-Miles Test - auf. BeispieleThe agents according to the invention are produced by stirring. If necessary, the product obtained can be decanted or filtered to remove foreign bodies and / or agglomerates. Immediately after production, the agents have a viscosity - measured at 20 ° C. using a Brookfield viscometer (model RVT, spindle 1, 60 rpm) - below 130, preferably below 100, in particular below 50 mPas and a foam height below from 100, preferably below 80, in particular not more than 60 ml - measured at 20 ° C. in a Ross-Miles test. Examples
Die Rezepturen 1 und 2 sind erfindungsgemäß, die Rezeptur V1 dient zum Vergleich. Unmittelbar nach der Herstellung wurde bei 20 °C die Viskosität mit Hilfe eines Brookfield-Viskosimeters (Modell RVT, Spindel 1 , 60 Upm) und das Schaumvermögen im Ross-Miles Test bestimmt. Die Ergebnisse sind in Tabelle 1 zusammengefaßt (Mengenangaben als Gew.-%).Recipes 1 and 2 are according to the invention, recipe V1 is used for comparison. Immediately after production, the viscosity was determined at 20 ° C. using a Brookfield viscometer (model RVT, spindle 1, 60 rpm) and the foaming power in the Ross-Miles test. The results are summarized in Table 1 (quantitative data as% by weight).
