Abstract

The invention relates to a cleaning agent, particularly for textiles which has a content of milk proteins. Milk proteins are suitable for an at least partial substitution of the polyphosphates contained in conventional detergents. However, they are particularly advantageously used in textile dyeing and high pressure cleaning. With particular advantage, they can be added together with a surfactant mixture.

Description

Die Erfindung betrifft die Verwendung von Casein in Verbindung mit einem Tensidgemisch als Hochdruck- und Auskochreinigungsmittel.The invention relates to the use of casein in combination with a surfactant mixture as a high-pressure and decoction cleaner.

Casein ist als Zusatz für Seifen schon seit langem bekannt, so wird in "Ullmann, Enzyklopädie der technischen Chemie", Band 3, 1916, Seiten 292 bis 297, insbesondere auf Seite 297, darauf hingewiesen, daß Toilettenseifen durch Zusatz von 10 % Caseinlösung vermehrt und in der Qualität verbessert werden können. Die Seife soll zarter und haltbarer werden und größere Schaumkraft haben. Aus DE-A-27 48 800, US-A-40 79 020 und EP-AI-0 013 585 ist es bei Geschirrspülmitteln, die für das Geschirrspülen von Hand bestimmt sind, bekannt, Casein in einer Menge von 0,25 bis 5 Gew.% zu verwenden. Die Aufgabe des Caseins ist dort, Alkylbenzolsulfonate, Alkylsulfonate und Alkylsulfate mindestens teilweise zu ersetzen, da diese dazu neigen, die Eigenschaften der Milde und auch des Abtropfens/Trocknens unter Weichwasserbedingungen nachteilig zu beeinflussen. In der DE-A-26 07 656 ist ein Wasch- und Reinigungsmittel für Textilien beschrieben, das zusätzlich zu Phosphataufbausalzen noch Komplexbildner, wie Phosphonsäuren, und Schutzkolloide, wie Casein, enthält.Casein has long been known as an additive for soaps, so it is pointed out in "Ullmann, Encyclopedia of Industrial Chemistry", Volume 3, 1916, pages 292 to 297, in particular on page 297, that toilet soap increases by adding 10% casein solution and can be improved in quality. The soap should become more delicate and durable and have greater foaming power. From DE-A-27 48 800, US-A-40 79 020 and EP-AI-0 013 585 it is known in the case of dishwashing detergents which are intended for manual dishwashing, casein in an amount of 0.25 to 5 % By weight to use. The task of casein there is to at least partially replace alkylbenzenesulfonates, alkylsulfonates and alkylsulfates, since these tend to adversely affect the properties of mildness and also of draining / drying under soft water conditions. DE-A-26 07 656 describes a washing and cleaning agent for textiles which, in addition to phosphate building salts, also contains complexing agents, such as phosphonic acids, and protective colloids, such as casein.

Es wurde gefunden, daß sich Casein in Verbindung mit einem Tensidgemisch hervorragend als Hochdruck- und Auskochreinigungsmittel eignet und in der Lage ist selbst starke Verkrustungen abzulösen. Dabei kann mit besonderem Vorteil auf die Mitverwendung von Polyphosphaten verzichtet werden.It has been found that casein in combination with a surfactant mixture is excellently suitable as a high-pressure and boil-out cleaning agent and is able to remove even strong incrustations. It is particularly advantageous to dispense with the use of polyphosphates.

Casein ist als Milchprotein biologisch abbaubar, so daß es keine Umweltprobleme mit sich bringt. Casein ist ein bei der Milchverwertung in großen Mengen anfallendes Nebenprodukt, für das durch die Erfindung gleichzeitig eine Verwendung geschaffen wird.As a milk protein, casein is biodegradable so that it does not pose any environmental problems. Casein is a by-product of milk processing in large quantities, for which the invention also creates a use.

Erfindungsgemäß verwendet werden Casein bzw. Caseinate.Casein or caseinates are used according to the invention.

Bereits sehr kleine Mengen an Milchproteinen ermöglichen eine starke Herabsetzung des Polyphosphatgehaltes. Normalerweise liegt das Milchprotein in Mengen von mehr als 5 bis 20 Gew.%, insbesondere 7 bis 15 Gew.% in der Trockensubstanz des Reinigungsmittels vor. In besonderen Fällen kann der Anteil jedoch auch höher liegen, besonders dann, wenn das Reinigungsmittel im übrigen nur das Tensidgemisch enthält.Even very small amounts of milk proteins make it possible to greatly reduce the polyphosphate content. The milk protein is normally present in the dry matter of the cleaning agent in amounts of more than 5 to 20% by weight, in particular 7 to 15% by weight. In special cases, however, the proportion can also be higher, especially if the cleaning agent otherwise only contains the surfactant mixture.

Casein ist im Handel in der Regel als Pulver, das in Wasser schwer löslich ist. Durch Erhöhen des pH-Wertes kann Casein jedoch in bekannter Weise löslich gemacht werden. Hierbei ist ein Löslichmachen unter Verwendung von Ammoniumhydroxid bevorzugt. Es können jedoch auch andere lösliche Caseinate verwendet werden.Casein is usually commercially available as a powder that is sparingly soluble in water. However, by increasing the pH, casein can be made soluble in a known manner. Solubilization using ammonium hydroxide is preferred. However, other soluble caseinates can also be used.

Das Hochdruck- bzw. Auskochreinigungsmittel ist vorzugsweise frei von Polyphosphaten.The high-pressure or decoction cleaner is preferably free of polyphosphates.

Die Verwendung des Hochdruck- bzw. Auskochreinigungsmittels aus Casein und Tensidgemisch erfolgt vorzugsweise zur Reinigung von stark verschmutzten Gegenständen, wie Maschinen, Apparate, Boots-, Schiffs- und Flugzeugkörpern und Schwimmbädern. Hierbei kommen die besonderen Fähigkeiten der Milchproteine zum Ablösen von groben Schmutzteilen zum Tragen. Es ist also nicht erforderlich, daß die starken Verschmutzungen vollständig aufgelöst werden. Es reicht vielmehr ein Ablösen des Schmutzes in Form von mehr oder weniger groben Partikeln aus.The use of the high-pressure or boil-out cleaning agent made of casein and surfactant mixture is preferably used for cleaning heavily soiled objects, such as machines, apparatus, boat, ship and aircraft bodies and swimming pools. The special abilities of milk proteins to remove coarse dirt come into play here. It is therefore not necessary for the heavy soiling to be completely dissolved. Rather, it is sufficient to remove the dirt in the form of more or less coarse particles.

Das erfindungsgemäße Reinigungsmittel kann in flüssiger Form vorliegen, was dann bevorzugt ist, wenn weitere Bestandteile des Reinigungsmittels ohnehin üblicherweise in flüssiger Form eingesetzt werden. Bei Vorliegen des Reinigungsmittels in flüssiger Form enthält es zweckmäßigerweise noch ein Konservierungsmittel , um eine bakterielle Zersetzung des Milchproteins zu vermeiden.The cleaning agent according to the invention can be in liquid form, which is preferred if further constituents of the cleaning agent are usually used in liquid form anyway. If the cleaning agent is in liquid form, it expediently also contains a preservative in order to avoid bacterial decomposition of the milk protein.

Zweckmäßigerweise erfolgt die Anwendung von Milchproteinen in Form von flüssigen Zubereitungen von aufgeschlossenem Milcheiweiß, die Konservierungsmittel enthalten. Diese flüssigen Zubereitungen werden in Kombination mit Tensidmischungen verwendet.Advantageously, milk proteins are used in the form of liquid preparations of digested milk protein which contain preservatives. These liquid preparations are used in combination with surfactant mixtures.

Die Eiweißlösung hat vorzugsweise folgende Zusammensetzung (Gewichtsteile pro Volumenteile):

  • 10 - 16 Casein oder Caseinate als Pulver,
  • 0,8 - 1,2 Teile Ammoniumhydroxid (25 %),
  • 0,8 - 1,2 Teile Konservierungsmittel,
  • aufgefüllt auf 100 Volumenteile Wasser.
The protein solution preferably has the following composition (parts by weight per part by volume):
  • 10 - 16 casein or caseinates as powder,
  • 0.8-1.2 parts ammonium hydroxide (25%),
  • 0.8 - 1.2 parts preservative,
  • made up to 100 volumes of water.

Die Tensidmischung kann folgende Zusammensetzung haben (Gewichtsteile pro Volumenteile):

  • 5 - 15 Teile Alkylpolyglycoläther,
  • 5 - 10 Diethylenglycolmonobutyläther (oder ähnliche Glycole) als Lösungsvermittler,
  • 5 - 10 Teile Metoxypropanolaminsalze als Reinigungsverstärker,
  • 5 - 15 Teile Tridecylalkohole mit 5 bis 8 Ethylenoxid,
  • 1 - 3 Teile Natriumcumolsulfonat (Pulver),
  • 1 - 8 Teile Industriealkohole, z.B. Isopropanol, aufgefüllt auf 100 Volumenteile Wasser.
The surfactant mixture can have the following composition (parts by weight per part by volume):
  • 5 - 15 parts of alkyl polyglycol ether,
  • 5 - 10 diethylene glycol monobutyl ether (or similar glycols) as solubilizers,
  • 5 - 10 parts of metoxypropanolamine salts as cleaning enhancers,
  • 5 - 15 parts of tridecyl alcohols with 5 to 8 ethylene oxide,
  • 1 - 3 parts of sodium cumene sulfonate (powder),
  • 1 - 8 parts of industrial alcohols, e.g. isopropanol, made up to 100 volumes of water.

Das Verhältnis von Eiweißlösung zu Tensidgemisch kann im Verhältnis von 1:2 bis 2:1 liegen, wobei es vorzugsweise 1:1 beträgt. Die Eiweißlösung enthält vorzugsweise 5 bis 20 Gew.% lösliches Milcheiweiß (Caseinate) und eine ausreichende Menge an Konservierungsmittel . Das Tensidgemisch enthält in der Regel 20 bis 60 Gew.% Netzmittel und wasserlösliche organische Lösungsmittel. Eiweißlösung und Tensidgemisch werden vorzugsweise in Form einer gemeinsamen flüssigen Mischung zubereitet und eingesetzt. Darin können, bezogen auf den Feststoffgehalt, etwa 10 bis 30 Gew.% Casein bzw. Caseinat und ca. 90 bis 70 Gew.% Tensidgemisch enthalten sein. Je nach Verwendungszweck wird diese flüssige Mischung dann um ein Vielfaches verdünnt. Das Tensidgemisch dient vorwiegend als Waschmittel zur Entfernung von Verkrustungen (aus Teer, Ölen usw.), bei Behältern, Foulardes, Spannrahmen, Sieben, Maschinen und Maschinenteilen, Klimaanlagen sowie Fahr- und Flugzeugkörpern. Für die Anwendung als Waschmittel für die Hochdruckreinigung wird das Gemisch aus Eiweißlösung und Tensidgemisch verdünnt, vorzugsweise im Verhältnis 1:3 bis 1:5. Hierdurch wird seine Viskosität gesenkt, damit es dem erhitzten Wasser des Hochdruckreinigers zudosiert werden kann. Ein solches Waschmittel eignet sich auch zur Reinigung durch Auskochen, was bei hartnäckigen Verschmutzungen mit der Hochdruckreinigung kombiniert werden kann.The ratio of protein solution to surfactant mixture can be in the ratio of 1: 2 to 2: 1, preferably 1: 1. The protein solution preferably contains 5 to 20% by weight of soluble milk protein (caseinates) and a sufficient amount of preservative. The surfactant mixture generally contains 20 to 60% by weight of wetting agent and water-soluble organic solvents. Protein solution and surfactant mixture are preferably prepared and used in the form of a common liquid mixture. Based on the solids content, this may contain about 10 to 30% by weight of casein or caseinate and about 90 to 70% by weight of surfactant mixture. Depending on the intended use, this liquid mixture is then diluted many times over. The surfactant mixture mainly serves as a detergent for removing incrustations (from tar, oils, etc.), in containers, foulards, stenter frames, sieves, machines and machine parts, air conditioning systems as well as vehicle and aircraft bodies. For use as a detergent for high-pressure cleaning, the mixture of protein solution and surfactant mixture is diluted, preferably in a ratio of 1: 3 to 1: 5. This lowers its viscosity so that it can be added to the heated water of the high-pressure cleaner. Such a detergent is also suitable for cleaning by boiling, which can be combined with high-pressure cleaning for stubborn soiling.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus dem nachfolgenden Beispiel in Verbindung mit den Unteransprüchen.Further features and advantages of the invention result from the following example in connection with the subclaims.

Beispielexample Hochdruckreinigungsmittel auf der Basis von MilchproteinenHigh-pressure cleaning agent based on milk proteins

Stark verschmutzte Maschinen, Apparate, Fahrzeuge, Schiffs-, Boots- und Flugzeugkörper sowie Innen-und Außenwände bzw. Verkleidungen können mit milcheiweißhaltigen Reinigungsmitteln im Hochdruckverfahren wirkungsvoll gereinigt werden, selbst dann, wenn die Verschmutzungen sonst nicht lösbar oder nur mit umweltschädlichen oder aggressiven Chemikalien beseitigt werden können. Wirkungsvoll ist die Kombination aus Eiweißlösung und Tensidgemisch auch bei der Hochdruckreinigung von Lebensmittelbetrieben, öffentlichen und privaten Schwimmbädern, Kläranlagen und Behältern. Für den Einsatz im Hochdruckreiniger wird die dickflüssige Mischung aus Tensidgemisch und Eiweißlösung zunächst 3- bis 5-fach verdünnt. Es werden dann ca. 20 bis 60 I dieser Lösung zu 3000 bis 5000 I erhitztem Waschwasser zudosiert. Eiweißlösung und Tensidgemisch liegen dann in einer ca. 150- bis 1250-fachen Verdünnung vor (0,08 bis 1,3 g/1 Waschflüssigkeit).Heavily soiled machines, apparatus, vehicles, ship, boat and aircraft bodies as well as inside and outside walls or cladding can be cleaned effectively with high-pressure cleaning agents containing milk protein, even if the dirt cannot be removed otherwise or can only be removed with environmentally harmful or aggressive chemicals can be. The combination of protein solution and surfactant mixture is also effective for high-pressure cleaning of food businesses, public and private swimming pools, sewage treatment plants and containers. For use in high-pressure cleaners, the viscous mixture of surfactant mixture and protein solution is first diluted 3 to 5 times. About 20 to 60 l of this solution are then metered into 3000 to 5000 l of heated washing water. The protein solution and surfactant mixture are then approximately 150 to 1250 times diluted (0.08 to 1.3 g / 1 washing liquid).

Anwendungsbedingungen: 70 bis 95 C, 70 bis 150 bar. Mit Hilfe einer Punktstrahldüse konnten mit diesem Hochdruckreinigungsmittel auch klebrige und verhärtete Verunreinigungen mit gutem Erfolg abgelöst werden.Application conditions: 70 to 95 C, 70 to 150 bar.
