Description

Die Erfindung betrifft Mischungen von Alkoxylaten mit schaumdämpfender und desinfizierender Wirkung und deren Verwendung in wäßrigen Reinigungsflotten für harte Oberflächen.The invention relates to mixtures of alkoxylates with foam-suppressing and disinfectant effect and their use in aqueous cleaning liquors for hard surfaces.

Die Reinigung von harten Oberflächen (wie Flaschen aus Kunststoff oder Glas, Geschirr aus Porzellan, Keramik, Glas oder Kunststoff und andere Gegenstände aus solchenWerkstoffen oder aus Metall) in gewerblichen und industriellen Reinigungsanlagen wird im allgemeinen mit einer wäßrigen Lösung von Alkalimetallhydroxiden, vorzugsweise Natronlauge (alkalische Reinigungsflotte) oder mit wäßrigen Säurelösungen (saure Reinigungsflotte) durchgeführt. Diese Reinigungsanlagen arbeiten mit großem Durchsatz und mit hohen Flottenbewegungen und Sprühintensitäten, um eine schnelle Ablösung und Emulgierung der anhaftenden Verunreinigungen zu gewährleisten. Wegen der hohen mechanischen Flottenbewegungen muß das System möglichst schaumarm oder schaumfrei sein, da übermäßige Schaumbildung zu Störungen in der Anlage führen kann. Zusätzliche Tendenzen zur Schaumbildung werden durch die vom Reinigungsgut in die Flotte eingeschleppten Verunreinigungen, besonders durch proteinhaltige Reste am Reinigungsgut, hervorgerufen. Im Falle der Flaschenreinigung gilt dies besonders auch für die zu entfernenden Etiketten, durch die Leimreste und Reste von Druckfarben einschließlich der in letzteren enthaltenden Tensidhilfsmittel in die Reinigungsflotte eingebracht werden.Cleaning hard surfaces (such as plastic or glass bottles, Porcelain, ceramic, glass or plastic dishes and other items from such materials or from metal) in commercial and industrial Cleaning equipment is generally with an aqueous solution of Alkali metal hydroxides, preferably sodium hydroxide solution (alkaline cleaning liquor) or with aqueous acid solutions (acid cleaning liquor). This Cleaning systems work with high throughput and with high Fleet movements and spray intensities to ensure quick detachment and To ensure emulsification of the adhering impurities. Because of the high mechanical liquor movements, the system must be as low-foam as possible or be foam-free, since excessive foaming leads to malfunctions in the system can lead. Additional tendencies to foam are caused by the Items to be cleaned into the fleet, especially through protein-containing residues on the items to be cleaned. In case of Bottle cleaning, this also applies to the labels to be removed the glue residues and residues of printing inks including those in the latter containing surfactant aids are introduced into the cleaning liquor.

Es ist schon seit langem bekannt, nichtionische Tenside als schaumunterdrückende Mittel in alkalischen oder sauren wäßrigen Basislösungen für die Reinigung von harten Oberflächen einzusetzen. Dies sind insbesondere Anlagerungsprodukte von Ethylenoxid und/oder Propylenoxid an Amine, Fettalkohole oder Alkylphenole, Polyglykoletherformale oder -acetale oder Blockcopolymerisate des Ethylen- und Propylenoxids.It has long been known to use nonionic surfactants as foam suppressants Agent in alkaline or acidic aqueous base solutions for the cleaning of hard surfaces. These are, in particular, investment products from Ethylene oxide and / or propylene oxide over amines, fatty alcohols or alkylphenols, Polyglycol ether formals or acetals or block copolymers of ethylene and Propylene oxide.

Eine weitere wichtige Forderung an Hilfsmittel für alkalische oder saure wäßrige Reinigungsflotten ist die desinfizierende Wirkung. Man ist nämlich bestrebt, die Reinigungsanlagen bei möglichst niedriger Temperatur zu betreiben, weil man dadurch nicht nur eine beträchtliche Energieeinsparung, sondern auch eine mildere Behandlung des Reinigungsgutes erreicht. Niedrige Temperaturen setzen aber voraus, daß die Reinigungsflotten (neben den genannten Eigenschaften, Reinigungs- und Benetzungsvermögen und Schaumarmut) auch eine hohe Mikroorganismen tötende Wirkung aufweisen.Another important requirement for auxiliaries for alkaline or acidic aqueous Cleaning liquors are the disinfectant effect. One strives for that Operating cleaning systems at the lowest possible temperature, because one not only a considerable energy saving, but also a milder one Treatment of the items to be cleaned reached. However, low temperatures set that the cleaning liquors (in addition to the properties mentioned, Cleaning and wetting ability and low foam) also a high Microorganisms have a killing effect.

In DE-A-25 23 588 (GB-A-1 488 108) werden Polyglykolethermischformale, in EP-B-322 781 endverschlossene Fettalkoholalkoxylate und in EP-A-694 606 Mischungen aus einem Fettalkoholethoxylatpropoxylat und einem Fettamin oder Fettaminethoxylat als schaumdämpfende Zusätze zu Reinigunsmitteln beschrieben. Erwähnt sei auch noch WO-A-96/10069, worin desinfizierende Reinigungsmittel für harte Oberflächen beschrieben werden. Im einzelnen geht es um die Verwendung einer Mischung aus einem Alkyl- und/oder Alkenyloligoglykosid und einem Fettalkoholalkoxylat zur Verstärkung der keimreduzierenden Wirkung von Desinfektionsmitteln enthaltenden Reinigungsmittel für harte Oberflächen. Als Desinfektionsmittel, deren Wirkung durch Zusatz der genannten Mischung erhöht werden soll, werden unter anderem auch Fettalkylpolyamine wie N,N-Bis-(3-aminopropyl)dodecylamin genannt. DE-A-3048642 beschreibt Tensidgemische zur Reinigung harter Oberflächen, insbesondere Flaschen, enthaltend Alkoxylate und quartäre Ammoniumsalze.DE-A-25 23 588 (GB-A-1 488 108) describes polyglycol ether mixed formals in EP-B-322 781 end-capped fatty alcohol alkoxylates and in EP-A-694 606 Mixtures of a fatty alcohol ethoxylate propoxylate and a fatty amine or Fatty amine ethoxylate is described as a foam-suppressing additive to cleaning agents. WO-A-96/10069, in which disinfectant cleaning agents for hard surfaces are described. In detail, it is about the use a mixture of an alkyl and / or alkenyl oligoglycoside and one Fatty alcohol alkoxylate to enhance the germ reducing effect of Cleaning agents containing disinfectants for hard surfaces. As Disinfectant, the effect of which is increased by adding the mixture mentioned should be, among other things, fatty alkyl polyamines such as N, N-bis (3-aminopropyl) dodecylamine called. DE-A-3048642 describes surfactant mixtures for cleaning hard surfaces, in particular Bottles containing alkoxylates and quaternary ammonium salts.

Es wurde nun gefunden, daß man mit einer Kombination von ausgewählten Alkoxylaten und Fettalkylpolyaminen eine unerwartet hohe synergistische Wirkung bezüglich Schaumunterdrückung und Keimtötung sowie Reinigungs- und Benetzungsvermögen erreicht. Dieses Ergebnis ist um so überraschender als Fettalkylpolyamine bekanntlich als starke Schaummittel gelten. It has now been found that one can use a combination of selected Alkoxylates and fatty alkyl polyamines have an unexpectedly high synergistic effect regarding foam suppression and germ killing as well as cleaning and Wetting ability reached. This result is all the more surprising than Fatty alkyl polyamines are known to be strong foaming agents.
