Description

Die Erfindung bezieht sich auf ein Reinigungsmittel gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a cleaning agent according to the preamble of patent claim 1.

Aus der US 2005/0255172 ist ein Desinfektionsmittel bekannt, welches neben Wasserstoffperoxid einen Gehalt an Azetylenglykol (mit freien Hydroxylgruppen) aufweist.From the US 2005/0255172 a disinfectant is known which in addition to hydrogen peroxide has a content of acetylene glycol (with free hydroxyl groups).

Weiter ist aus der WO02051970 ein als trocken bezeichnetes Reinigungsmittel bekannt, welches 0,5 % Wasser und 0,5 % eines als Entschäumer wirkenden speziellen Polydimethylsiloxans enthält und wovon 6 Kilogramm in 200 Liter Wasser aufgelöst werden.Next is from the WO02051970 a cleaning agent, referred to as dry, which contains 0.5% of water and 0.5% of a special polydimethylsiloxane acting as a defoamer and of which 6 kg are dissolved in 200 liters of water.

Der Erfindung liegt die Aufgabe zugrunde ein Reinigungsmittel zu schaffen, welches eine verbesserte Reinigungswirkung zeigt und optimale Resultate bei dessen Verwendung zur Reinigung von wasserbeständigen, insbesondere von nicht-textilen Oberflächen erzielt. Eine weitere Aufgabe besteht darin ein Reinigungsmittel zu schaffen, welches sich optimal für den Einsatz in Scheuersaugmaschinen eignet.The invention has for its object to provide a cleaning agent which shows an improved cleaning effect and achieves optimum results in its use for cleaning water-resistant, especially non-textile surfaces. Another object is to provide a cleaning agent which is optimally suited for use in scrubber driers.

Die Erfindung löst die gestellte Aufgabe mit einem Reinigungsmittel, welches die Merkmale gemäss dem Anspruch 1 aufweist.The invention solves the problem with a cleaning agent having the features according to claim 1.

Im Gegensatz zu herkömmlichen Reinigungsverfahren für Textilien basiert die Wirkungsweise des erfindungsgemässen Reinigungsmittels weniger auf dem Prinzip der Schmutzemulgierung durch Tenside, sondern besteht aus der Kombination zweier Reinigungstechnologien. Durch das verwendete Netzmittel wird die Oberflächenspannung des mit Wasser verdünnten Reinigungsmittels in kürzester Zeit (weniger als 1 Sekunde) auf unter 30mN/m (bei Raumtemperatur gemessen) gesenkt, was der wässerigen Reinigungslösung in Kombination mit der mechanischen Kraft der Reinigung die Möglichkeit bietet Schmutzpartikel in der Reinigungsflotte zu suspendieren. Durch die Kombination mit einem Antiredepositionsmittel werden die Schmutzpartikel in der Schwebe gehalten was einer Redeposition entgegenwirkt.In contrast to conventional cleaning methods for textiles, the mode of action of the inventive cleaning agent is based less on the principle of soil emulsification by surfactants, but consists of the combination of two cleaning technologies. The wetting agent used lowers the surface tension of the detergent diluted with water in less than 1 second to below 30mN / m (measured at room temperature), which in combination with the mechanical power of cleaning offers the possibility of dirt particles in the water to suspend the cleaning liquor. By combining with an anti redeposition agent, the dirt particles are held in suspension, which counteracts a Redeposition.

Der Emulgator ermöglicht dem schlecht wasserlöslichen Netzmittel eine schnelle, homogene Verteilung in der Reinigungsflotte und verleiht ihr überraschenderweise eine stark verbesserte emulgierende Wirkung. Die so suspendierten, schwach negativ geladenen, Schmutzpartikel werden dank den negativen Ladungen der neutralisierten Polyasparaginsäure elektrosterisch in der Schwebe gehalten. Im Gegensatz zur bekannten Anwendung von Polyasparaginsäure in textilen Waschmittelflotten wird diese hier nicht zur Bindung der vorhandenen Ca2+-Ionen, sondern zur elektrosterischen Abstossung der negativ geladenen Schmutzpartikel durch die ebenfalls negativ geladenen, langkettigen Moleküle verwendet.The emulsifier allows the poorly water-soluble wetting agent a fast, homogeneous distribution in the cleaning liquor and surprisingly gives her a greatly improved emulsifying effect. The so-suspended, slightly negatively charged, dirt particles are electrostatically suspended due to the negative charges of the neutralized polyaspartic acid. In contrast to the known application of polyaspartic acid in textile detergent liquors, this is not used here for binding the Ca 2+ ions present, but for the electrosteric repulsion of the negatively charged dirt particles by the likewise negatively charged, long-chain molecules.

Die durch die Erfindung erreichten Vorteile sind im Wesentlichen die folgenden:

  • die negativ geladenen Schmutzpartikel werden elektrosterisch abgestossen;
  • durch einen Überschuss an aquatisierten, negativ geladenen Komplexbildner-Anteilen wird eine gegenseitige Abstossung zu den erfahrungsgemäss meist negativ geladenen Schmutzteilchen bewirkt;
  • die Flotte zeigt eine extrem gute Antiredepositionswirkung; und
  • überraschenderweise ergibt sich eine stark verbesserte Emulgierfähigkeit des erfindungsgemässen Reinigungsmittels, was auf eine synergistische Wirkung der Emulgatoren zurückzuführen ist; und
  • es kommen keine hochschäumenden Tenside zur Anwendung, so dass auf Entschäumer verzichtet werden kann.
The advantages achieved by the invention are essentially the following:
  • the negatively charged dirt particles are repelled electrostatically;
  • by an excess of aquatisierten, negatively charged complexing agent shares a mutual rejection to the experience usually causes negatively charged dirt particles;
  • the fleet shows an extremely good anti-redeposition effect; and
  • Surprisingly, there is a greatly improved emulsifying ability of the inventive cleaning agent, which is due to a synergistic effect of the emulsifiers; and
  • There are no high-foaming surfactants used, so that can be dispensed defoamer.

Weitere vorteilhafte Ausgestaltungen der Erfindung können wie folgt kommentiert werden:
Das negativ geladene, organische Makromolekül ist vorteilhafterweise ein polymeres Antiredepositionsmittel und kann aus folgenden Substanzklassen ausgewählt werden: Aminopolycarboxylate, organische Phosphonate, Polycarboxylate oder Copolymere davon. Im speziellen kann das mindestens eine negativ geladene, organische Makromolekül eine Polyasparaginsäure oder wasserlösliche Salze davon sein.Further advantageous embodiments of the invention can be commented on as follows:
The negatively charged organic macromolecule is advantageously a polymeric anti-redeposition agent and may be selected from the following classes of substances: aminopolycarboxylates, organic phosphonates, polycarboxylates or copolymers thereof. In particular, the at least one negatively charged organic macromolecule may be a polyaspartic acid or water-soluble salts thereof.

Das negativ geladene, organische Makromolekül kann auch ein Polyacrylat sein, z.B. ein acrylisches Homopolymer, vorzugsweise mit einem Molekulargewicht von 4'000 bis 6'000.The negatively charged organic macromolecule may also be a polyacrylate, eg, an acrylic homopolymer, preferably having a molecular weight of 4,000 to 6,000.

The wetting agent may also comprise one or more ethoxylated acetylenediols.

Der nichtionische Emulgator ist aus der Gruppe der Fettalkoholalkoxylate ausgewählt; der anionische Emulgator ist aus der Gruppe der Alkylsulfate oder Alkylethersulfate ausgewählt; der kationische Emulgator ist aus der Gruppe der quartären Ammoniumverbindungen ausgewählt und der amphotere Emulgator ist aus der Gruppe der Betaine und Sultaine ausgewählt. Der Emulgator kann auch ein oder mehrere, vorzugsweise verzweigte, ethoxylierte Fettalkohole umfassen.The nonionic emulsifier is selected from the group of fatty alcohol alkoxylates; the anionic emulsifier is selected from the group of alkyl sulfates or alkyl ether sulfates; the cationic emulsifier is selected from the group of quaternary ammonium compounds and the amphoteric emulsifier is selected from the group of betaines and sultaines. The emulsifier may also comprise one or more, preferably branched, ethoxylated fatty alcohols.

Die Polyasparaginsäure (oder ihre Salze davon) weist vorzugsweise eine durchschnittliche Molmasse zwischen 1000 - 10'000 g/mol, vorzugsweise zwischen 2000-3000 g/mol auf.The polyaspartic acid (or its salts thereof) preferably has an average molecular weight between 1000-10,000 g / mol, preferably between 2000-3000 g / mol.

Zweckmässigerweise beträgt die Partikelgrössenverteilung D50 des mindestens einen negativ geladenen, organischen Makromoleküls (und vorzugsweise die mindestens eine Polyasparaginsäure oder wasserlösliche Salze, welche in Partikelform vorliegen) 0,1 mm. Eine Partikelgrössenverteilung D50 von 0,07 mm oder gar von 0,01 mm ergibt besonders gute Resultate.Conveniently, the particle size distribution D50 of the at least one negatively charged organic macromolecule (and preferably the at least one polyaspartic acid or water-soluble salts which are in particulate form) is 0.1 mm. A particle size distribution D50 of 0.07 mm or even 0.01 mm gives particularly good results.

Das Reinigungsmittel wird in granularer oder tablettierter Form verwendet, was die Lagerung vereinfacht. Die Tabletten weisen zweckmässigerweise ein Volumen von mindestens 1 cm3, vorzugsweise mindestens 5 cm3 auf. Das Volumen beträgt zweckmässigerweise höchstens 100 cm3, vorzugsweise höchstens 12 cm3.The cleaning agent is used in granular or tableted form, which simplifies storage. The tablets have expediently a volume of at least 1 cm 3 , preferably at least 5 cm 3 . The volume is expediently at most 100 cm 3 , preferably at most 12 cm 3 .

Der maximale Durchmesser der Tabletten beträgt zweckmässigerweise 10 cm, vorzugsweise 7 cm. Der minimale Durchmesser der Tabletten beträgt zweckmässigerweise 1 cm, vorzugsweise 3 cm. Diese Dimensionierungen ermöglichen eine optimale Dosierung und Auflösung in Wasser.The maximum diameter of the tablets is expediently 10 cm, preferably 7 cm. The minimum diameter of the tablets is expediently 1 cm, preferably 3 cm. These dimensions allow for optimal dosing and dissolution in water.

Das erfindungsgemässe Reinigungsmittel wird zweckmässigerweise kurz vor seinem Gebrauch in Wasser aufgelöst. Bezogen auf einen Gewichtsteil der Summe der drei Komponenten a) + b) + c) können 500 - 100'000 Gewichtsteile Wasser zu dessen Auflösung verwendet werden. Zweckmässigerweise können 600 bis 1900 Gewichtsteile Wasser, vorzugsweise 900 bis 1300 Gewichtsteile Wasser zu dessen Auflösung verwendet werden.The detergent according to the invention is expediently dissolved in water shortly before use.

Conveniently, 600 to 1900 parts by weight of water, preferably 900 to 1300 parts by weight of water can be used for its dissolution.

Vorteilhafterweise enthält das Reinigungsmittel noch zusätzlich eine in Wasser aufquellende Substanz, z.B. Polyvinylpyrrolidon. Dadurch löst sich das in granularer oder tablettierter Form vorliegende Reinigungsmittel rascher in Wasser auf. Das als Tablette geformte Reinigungsmittel sollte sich zweckmässigerweise in weniger als 10 Minuten, vorzugsweise weniger als 2 Minuten rückstandfrei in Wasser lösen.
