Description

"Mittel zur maschinellen Reinigung und Desinfektion von Textilien" "Means for machine cleaning and disinfection of textiles"
Aus der europäischen Patentschrift 156 275 sind antimikrobiell wirksame Substanzen bekannt, die etwa durch Umsetzen von n-substituierten Propylen- diaminen der FormelFrom European patent specification 156 275 antimicrobial substances are known, for example by reacting n-substituted propylene diamines of the formula
R-NH-CH2-CH2-CH2-NH2,R-NH-CH 2 -CH2-CH 2 -NH2,

NH2,NH 2 ,
in der R^ einen Alkylrest mit 1 - 4 Kohlenstoffatomen oder ein Wasser¬ stoffatom bedeutet, wobei das molare Verhältnis der beiden Reaktionspart¬ ner 1 : 1 bis 1 : 2 beträgt, erhältlich sind. Die Umsetzungsprodukte (wei¬ terhin Komponente U genannt) können gegebenenfalls weiter mit Ethylen- oder Propylenoxid und/oder mit anorganischen oder organischen Säuren um¬ gesetzt werden. Derartige Mittel sind unter anderem als Zusätze zu Reini- gungs- und Desinfektionsmitteln für Textilien beispielsweise in Wäsche¬ reien zu gebrauchen. Weiterhin ist hiernach bekannt, daß man für flüssige Tensidzubereitungen derartiger Mittel als Lösungsmittel außer Wasser üb¬ liche organische Lösungsmittel, insbesondere Alkohole und Glykolether ver¬ wenden kann. Diethylenglykolmonobutylether werden nicht genannt. Auch pro- poxylierte Fettalkoholethoxylate werden nicht als Tenside vorgeschlagen. Aus der WO 91/13965 sind wäßrige Mittel zur Reinigung und Desinfektion von Gegenständen aus medizinischen Einrichtungen bekannt, die die vorstehend genannten antimikrobiell wirksamen Substanzen sowie ein oder mehrere orga- nische Lösungsmittel, insbesondere niedere Alkohole Glykole und Glykol- ether, unter anderem auch Diethylenglykolmonobutylether enthalten. Zwar wird dieser Ether auch mit einem propoxylierten Fettalkoholethoxylat kom¬ biniert, aber die angegebene Rezeptur enthält so viele weitere Bestand¬ teile, daß die Lehre der vorliegenden Erfindung daraus nicht abgeleitet werden konnte. Die Verwendung derartiger Mittel zur Reinigung und Desin¬ fektion von Textilien in Waschmaschinen wird dort ebenfalls nicht erwähnt. Im allgemeinen werden bei der Konfektionierung der Komponente U in flüs¬ sigen Mitteln Isopropanol oder 1,2-Propylenglykol als Lösungsvermittler verwendet.in which R 1 denotes an alkyl radical with 1 to 4 carbon atoms or a hydrogen atom, the molar ratio of the two reaction partners being 1: 1 to 1: 2. If appropriate, the reaction products (also called component U) can be reacted further with ethylene oxide or propylene oxide and / or with inorganic or organic acids. Such agents can be used, inter alia, as additives to cleaning and disinfecting agents for textiles, for example in laundries. It is also known hereafter that, for liquid surfactant preparations of such compositions, organic solvents, in particular alcohols and glycol ethers, can be used as solvents besides water. Diethylene glycol monobutyl ethers are not mentioned. Propoxylated fatty alcohol ethoxylates are also not proposed as surfactants. WO 91/13965 discloses aqueous compositions for cleaning and disinfecting objects from medical facilities which contain the abovementioned antimicrobial substances and one or more organic substances. African solvents, in particular lower alcohols, glycols and glycol ethers, including diethylene glycol monobutyl ether. Although this ether is also combined with a propoxylated fatty alcohol ethoxylate, the recipe given contains so many further constituents that the teaching of the present invention could not be derived from it. The use of such agents for cleaning and disinfecting textiles in washing machines is also not mentioned there. In general, isopropanol or 1,2-propylene glycol are used as solubilizers in the assembly of component U in liquid agents.
Bei der Herstellung vertriebsfertiger Reinigungs- und Desinfektionsmittel für Textilien in Waschmaschinen wurde nun gefunden, daß man zu deutlich besseren Ergebnissen kommt, wenn man bei Gemischen aus nichtionischen Ten- siden und antimikrobiellen Wirkstoffen gemäß Komponente U in Wasser als nichtionisches Tensid Ci2-C*i4-Alkanol, umgesetzt mit 5 Mol Ethylenoxid (EO) und anschließend 4 Mol Propylenoxid (PO) (Dehypon(R) LS 54) und als Lösungsvermittler anstelle von Isopropanol oder 1,2-Propylenglykol Diethy¬ lenglykolmonobutylether verwendet. Die Rezepturen bleiben dann auch nach längerer Lagerzeit klar und dünnflüssig und weisen keinerlei Trübungen auf, wobei sich die Viskosität der Mittel in Abhängigkeit von der Tempera¬ tur kaum ändert. Auch nach mehrmonatiger Lagerung im Klimaschrank bei wechselnden Temperaturen zwischen minus 10 °C und plus 40 °C bleiben sie stabil und erleiden keine Phasentrennungen. Die auf diese Weise konfekti¬ onierten Mittel sind damit leicht zu fördern und zu dosieren, was insbe¬ sondere ihre gute Anwendbarkeit in vollautomatisch arbeitenden Maschinen in gewerblichen Wäschereien garantiert. Auf diese Weise lassen sich die wertvollen Eigenschaften des antimikrobiellen Mittels auch für die Desin¬ fektion für Textilien nutzen.In the manufacture of ready-to-sell cleaning and disinfectants for textiles in washing machines, it has now been found that significantly better results are obtained if mixtures of nonionic surfactants and antimicrobial active ingredients according to component U in water are used as the nonionic surfactant Ci2-C * i4- Alkanol, reacted with 5 mol of ethylene oxide (EO) and then 4 mol of propylene oxide (PO) (Dehypon ( R ) LS 54) and used as a solubilizer instead of isopropanol or 1,2-propylene glycol diethylene glycol monobutyl ether. The formulations then remain clear and thin even after a long storage period and have no cloudiness, the viscosity of the agents hardly changing as a function of the temperature. Even after several months of storage in a climatic cabinet with changing temperatures between minus 10 ° C and plus 40 ° C, they remain stable and do not suffer any phase separations. The agents thus assembled are thus easy to convey and dose, which in particular guarantees their good applicability in fully automatic machines in commercial laundries. In this way, the valuable properties of the antimicrobial agent can also be used for disinfection for textiles.
Andere nichtionische Tenside, wie beispielsweise ein mit 6 - 20 Mol Ethy¬ lenoxid und anschließend mit Butylenglykol endgruppenverschlossener Cιo~ Ci4-0xoalkohol (Plurafac(R) LF 220), ein mit 6,4 Mol Ethylenoxid und 1,2 Mol Propylenoxid umgesetzter Cιo-Ci4-Fettalkohol (Dehypon(R) 980), ein mit 4 Mol Ethylenoxid umgesetzter Ci4/i5-Fettalkohol (Dobanol(R) 45/4), ein mit 3 Mol Ethylenoxid umgesetzter Isotridecylalkohol (Lutensol(R) T03) oder ein mit Butylenglykol endgruppenverschlossenes Umsetzungsprodukt aus einem Ci2-Ci4-Fettalkohol und 10 Mol Ethylenoxid (Dehypon(R) LS 104) führ¬ ten nicht zu den erfindungsgemäßen Ergebnissen.Other nonionic surfactants, such as, for example, a 6-20 mole ethylene oxide and subsequently C 1 -C 4 -o-xo alcohol (Plurafac ( R ) LF 220) end-capped with butylene glycol, a C 1 -C reaction with 6.4 mole ethylene oxide and 1.2 mole propylene oxide Ci4 fatty alcohol (Dehypon ( R ) 980), a Ci4 / i5 fatty alcohol (Dobanol ( R ) 45/4) reacted with 4 mol ethylene oxide, an isotridecyl alcohol (Lutensol ( R ) T03) reacted with 3 mol ethylene oxide or a reaction product end-capped with butylene glycol from a Ci2-Ci4 fatty alcohol and 10 mol ethylene oxide (Dehypon ( R ) LS 104) did not lead to the results according to the invention.
Die Menge an Komponente U in den Reinigungsmitteln beträgt etwa 15 bis 60, vorzugsweise etwa 35 bis 55 Gew.-%. Das Tensid wird in Mengen von etwa 10 bis etwa 30, vorzugsweise von etwa 12 bis 20 Gew.-% eingesetzt. Die Menge an Diethylenglykolmonobutylether beträgt etwa 10 bis 30, vorzugsweise etwa 15 - 20 Gew.-%, der Rest, der jeweils bis 100 Gew.-% fehlt, besteht aus Wasser, dessen Gesamtanteil etwa 20 bis 40, vorzugsweise etwa 25 bis 35 Gew.-% beträgt. Gegebenenfalls können den Reinigungs- und Desinfektions¬ mitteln auch noch Schaumregulatoren zugesetzt werden wie beispielsweise Silikonöle, Paraffine, Ci2-C*i8-Fettalkohol + x E0 + y PO; BASF (Plura- fac(R) LF 403), Phosphorsäuremono-/distearylester oder ein mit Butylengly¬ kol endgruppenverschlossenes Umsetzungsprodukt aus einem Ci2-Ci8-Fettal- kohol und 9 Mol E0 (Dehypon(R) LT 104). Ihre Mengen sollen nicht mehr als etwa 5 Gew.-%, vorzugsweise etwa 0,5 bis 2,0 Gew.-% betragen. Die Mittel werden durch Zusammengeben und Vermischen der einzelnen Bestandteile her¬ gestellt. Der pH-Wert der unverdünnten Lösungen liegt bei etwa 8,7, in Konzentrationen von 1 Gew.-% etwa bei 9,8. Die erfindungsgemäßen Reini¬ gungs- und Desinfektionsmittel können auch in wäßriger Verdünnung bei Kon¬ zentrationen von etwa 0,5 bis 6 Gew.-% bei 60 °C und von etwa 6 bis 12 Gew.-% bei 40 °C zur Wäsche, Desinfektion und Reinigung verwendet werden. Die bakteriologische und viruzide Wirksamkeit entsprach den Erwartungen. The amount of component U in the cleaning agents is about 15 to 60, preferably about 35 to 55% by weight. The surfactant is used in amounts from about 10 to about 30, preferably from about 12 to 20,% by weight.
