Wäßrige Reinigungsmittelkonzentrate mit einem Gehalt an stabilisierten Enzymen Die Erfindung betrifft flüssige oder pastenförmige wäßrige Reinigungsmittelkonzentrate mit einem Gehalt an stabilisierten Enzymen, die sich durch ein hohes Reinigungsvermögen sowie. anwendungstechnische Vorteile, insbesondere hinsichtlich der Dosierbarkeit in automatischen Dosiervorrichtungen, auszeichnen. Aqueous cleaning agent concentrates with a content of stabilized Enzymes The invention relates to liquid or pasty aqueous cleaning agent concentrates With a content of stabilized enzymes, which are characterized by a high cleaning power as. application advantages, in particular with regard to metering in automatic dosing devices.
Zur Zeit werden für SpUl- und Reinigungszwecke im- -Haushalt und in gewerblichen Betrieben, vor allem als Geschirrspülmittel für das maschinelle Geschirrspülen, vorzugsweise alkalisch reagierende pulverförmige Reinigergemische auf der Basis von anorganischen Salzen eingesetzt. Zur Verbesserung der Reinigungswirkung gegen Eiweiß- und Stärke-Verschmutzungen können derartige Mittel Zusätze an Enzymen enthalten. Diese Mittel werden bei Haushaltsgeschirrspülmaschinen vor jedem Programm von Hand zugegeben, da einfache und zuverlässig arbeitende Dosiergeräte für pulverförmige Produkte noch nicht zur Verfügung stehen.For flushing and cleaning purposes in the household and in commercial operations, especially as dishwashing detergents for machine dishwashing, preferably alkaline powder detergent mixtures on the basis of inorganic salts used. To improve the cleaning effect against Protein and starch soiling can contain enzymes of this type. In the case of household dishwashers, these funds are manually added before each program Admittedly, because simple and reliable dosing devices for powdery Products are not yet available.
Man hat daher immer wieder versucht, flüssige Reiniger zu verwenden, da diese sich mit den heute schon verfügbaren Dosiergeräten auf einfache und. sichere Weise den Spülflotten zusetzen lassen. Die derzeit Ublichen aktivchlorhaltigen flüssigen Reiniger sind Jedoch zur Erzielung einer guten Aktivehlorstabilität hoch alkalisch eingestellt, was durch Atzalkalizusatz erreicht wird. Damit scheiden derartige Mittel wegen ihrer Gefährlichkeit, speziell für Kinder und wegen ihres Korrosionsverhaltens gegenüber dem Spülgut für den Gebrauch in Haushaltsgeschirrspülmaschinen weitgehend aus. Aus Korrosionsgründen gilt dies z. T. auch für das gewerbliche Geschirrspülen. Mit aktivehlorfreien alkalischen flüssigen Reinigern lassen sich dagegen keine befriedigenden Reinigungsergebnisse erzielen. Es besteht daher seit langem der Wunsch, die Reinigungskraft flüssiger Reiniger durch Enzymzusätze aufzuwerten. Dies scheiterte bisher jedoch an der mangelhaften Stabilität der Enzyme in wäßrigen Reinigergemischen.Therefore one has tried again and again to use liquid cleaning agents, since these are easy to use with the dosing devices that are already available today. safe Let it add to the washing liquor. The currently common active chlorine-containing liquids However, cleaning agents are highly alkaline in order to achieve good stability in active substances set, which is achieved by adding caustic alkali. This means that such means separate because their dangerousness, especially for children and because of theirs Corrosion behavior towards the wash ware for use in household dishwashers largely off. For reasons of corrosion, this applies z. Sometimes also for commercial dishwashing. With active chloride-free alkaline liquid cleaners, on the other hand, no satisfactory cleaners can be achieved Achieve cleaning results. There has therefore long been a desire to be the cleaning power to upgrade liquid cleaner with enzyme additives. So far, however, this has failed the inadequate stability of the enzymes in aqueous cleaning agent mixtures.

Von besonderem Interesse sind Stärke, Eiweiß oder Fette spaltende Enzyme, wie Amylasen,: Proteasen und Lipasen. Die Enzyme werden nach verschiedenen Verfahren aus Bakterienstämmen, Pilzen, Hefen oder tierischen Organen gewonnen. Meist handelt es sich dabei um Enzymgemische, die eine kombinierte Wirkung gegenüber Stärke, Eiweiß und Fetten besitzen. Die aus Bazillus subtilis gewonnenen Enzympräparate weisen den für die praktische Verwendung besonderen Vorteil auf, daß sie auch im alkalischen Milieu relativ beständig sind und bei Temperaturen zwischen 45 und 50° C noch nicht nennenswert inaktiviert werden. Der vorzugsweise Anteil der Enzyme am Reinigungsmittelkonzentrat beträgt etwa 1 - 5 Gewichtsprozent.The enzymes used are those of animal and vegetable origin, in particular the active ingredients obtained from digestive enzymes, yeast and bacterial strains in Question. They usually represent a complex mixture of different enzymatic active ingredients. Of particular interest are starch, protein or Fat-splitting enzymes such as amylases: proteases and lipases.

Außer den genannten Bestandteilen können die beanspruchten Gemische anorganische Salze wie Natriumsulfat, Natriumchlorid, oder Ammoniumchlorid, ferner Farbstoffe, Verdickungsmittel sowie saure oder alkalisch reagierende bzw. puffernde anorganische oder organische Verbindungen zur Einstellung eines für die Enzymwirkung vorteilhaften pH-Wertes enthalten. Die bevorzugten pH-Werte liegen - Je nach Art des Enzyms - zwischen 4 bis 12, vorzugsweise 5,5 bis 8,5 -. In addition to the constituents mentioned, the claimed mixtures inorganic salts such as sodium sulfate, sodium chloride, or ammonium chloride, furthermore Colorants, thickeners and acidic or alkaline reacting or buffering agents inorganic or organic compounds to adjust one for the enzyme action advantageous pH. The preferred pH values are - depending on the species of the enzyme - between 4 to 12, preferably 5.5 to 8.5 -.
Die Herstellung handelsfähiger Konzentrate erfolgt durch Auflösen der einzelnen Bestandteile in Wasser, wobei man zweckmäßig so vorgeht, daß man die Enzyme und Zucker einerseits und die anorganischen Bestandteile und sonstigen Hilfsstoffe andererseits getrennt in Lösung bringt und die Lösungen dann vereinigt. Aus ökonomischen Gründen werden möglichst konzentrierte Lösungen angestrebt, doch sind Je nach Art der gewählten anorganischen und organischen Komponenten usw. - Wassergehalte von wenigstens 4'o Gewichtsprozent erforderlich, um Phasentrennungen oder das Auskristallisieren von Einzelbestandteilen, insbesondere bei tieferen Temperaturen, zu vermeiden. The production of marketable concentrates takes place by dissolving of the individual components in water, it is expedient to proceed in such a way that the Enzymes and sugars on the one hand and the inorganic components and other auxiliaries on the other hand, brings separately into solution and then combined the solutions. For economic The aim is to find solutions that are as concentrated as possible, but depending on the type the selected inorganic and organic components, etc. - water contents of at least 4'o percent by weight required to prevent phase separation or crystallization of individual components, especially at lower temperatures.
Die Produkte können Je nach Konzentration und Inhaltsstoffen dünnflüssig, hochviskos oder pastenförmig sein. Depending on the concentration and ingredients, the products can be thin, be highly viscous or pasty.
Die beanspruchten Produkte lassen sich als Reinigungsmittel im Haushalt, in GaststEtten, gewerblichen Betrieben usw. zur Säuberung von Kacheln, Fußboden Tischf,lächen, Töpfen, Pfannen Grilleinrichtungen, Milchkannen u. a. Gerätschaften, die mit Nahrungsmitteln oder sonstigen eiweiß- oder stärkehaltigen Produkten in Berührung kommen, verwenden. The claimed products can be used as cleaning agents in the household, in restaurants, commercial establishments, etc. for cleaning tiles, floors Table tops, pots, pans, barbecue equipment, milk cans, etc. Equipment, those with food or other protein or starchy products in Come into contact, use.
Insbesondere sind die Produkte jedoch als Geschirrspülmittel für das maschinelle Geschirrspülen vorgesehen, da sie sich ohne weiteres in üblichen Flüssig-Dosiereinrichtungen, wie sie auch bei Haushaltsgeschirrspülmaschinen verwendet werden können, einsetzen lassen. Damit ist eine Bevorratung des Spülmittels in der Spülmaschine möglich, wodurch das lästige Zugeben des Reinigungsmittels von Hand vor jedem Spülgang entfällt. Die Mittel der Erfindung tragen somit zu einer Vereinfachung und Automatisierung des Reinigungsprozesses bei. In particular, however, the products are used as dishwashing detergents Machine dishwashing is provided as it is readily available in normal Liquid dispensers like them also for household dishwashers can be used. This means that there is a supply of detergent possible in the dishwasher, which eliminates the inconvenience of adding the cleaning agent No need to hand before each wash cycle. The means of the invention thus contribute to one Simplification and automation of the cleaning process.
Die Anwendungskonzentrationen in der Spülflotte betragen bei HaushaltsgeschirrspUlmaschinen etwa 2 - 15 g/l, wobei die Konzentration des eingesetzten Mittels zu berücksichtigen ist. Es werden Temperaturen bis zu etwa 50 - 600 C angewendet.The use concentrations in the washing liquor are for household dishwashers about 2-15 g / l, taking into account the concentration of the agent used is. Temperatures up to about 50 - 600 C are used.
Höhere Temperaturen können leicht zu einer vorzeitigen Inaktivierung der Enzyme führen. Die Spüldauer richtet sich nach dem Spülprogramm der betreffenden Spülmaschine und beträgt üblicherweise 8 - 30 Minuten.Higher temperatures can easily cause premature inactivation of enzymes lead. The duration of the wash depends on the wash program in question Dishwasher and usually takes 8-30 minutes.
Die beanspruchten Reinigungsmittelkonzentrate zeichnen sich durch ein außerordentlich gutes Reinigungsvermögeng auch gegenüber hartnäckigen Anschmutzungen, wie Eiweiß-Stärke-Belägen aus. Sie sind hinsichtlich der Reinigungswirkung durchaus mit handelsüblichen pulverförmigen Reinigerkombinationen vergleichbar oder übertreffen diese noch. Weitere Vorteile sind neben der leicht zu handhabenden flüssigen Form oder der Dosierfähigkeit das günstige Korrosionsverhalten gegenüber dem Reinigungsgut und die relative Ungefährlichkeit, besonders im Haushalt und gegenüber Kindern Zur Prüfung des Reinigungsergebnisses der erfindungsgemäßen enzymatischen Reinigerkonzentrate wurden Teller mit Kartoffel stärke- und Haferbreianschmutzungen, Tassen mit angetrockneten Teeresten und Teller mit Fettstiftbelägen gereinigt. Die Ver--suche wurden in einer Haushaltsgeschirrspülmaschine mit Düsseldorfer Stadtwasser (16° dH) durchgeführt.The claimed cleaning agent concentrates are characterized by an extremely good cleaning ability even against stubborn soiling, like protein-starch toppings. They are definitely in terms of the cleaning effect comparable or even better than commercially available powder detergent combinations this still. Further advantages are in addition to the easy-to-use liquid form or the dosing capability, the favorable corrosion behavior towards the items to be cleaned and the relative harmlessness, especially in the household and towards children Zur Examination of the cleaning result of the enzymatic cleaning concentrates according to the invention There were plates with potato starch and oatmeal stains, cups with dried-on ones Tea residues and plates cleaned with grease stick coatings. The tests were carried out in a Household dishwasher carried out with Düsseldorf city water (16 ° dH).
Im Reinigungsgang wurden 9 g Reinigerkonzentrat/l Spülflotte zudosiert. Dies entspricht der üblichen Dosierung eines festen Reinigergemisches mit etwa 3 g/l. Im nachfolgenden Klarspülgang, der mit enthärtetem Wasser durchgeführt wurde, wurden o,4 g/l eines handelsüblichen sauren Klarspülers eindosiert. Nach Beendigung des gesamten Spülprogrammes erfolgte jeweils die Beurteilung des Reinigungsvermögens der eingesetzten Reinigergemische. Die einzelnen Bewertungen erfolgten nach einem Punktsystem, das von 0 bis lo reichte, wobei 0 Punkte "ohne erkennbare Reinigungswirkung" und 10 Punkte restlose Beseitigung der Testanschmutzungen" bedeuteten. Es ergab sich hieraus eine Anzahl von Zwischenwerten, die eine differenzierte Aussage ermöglichten.In the cleaning cycle, 9 g detergent concentrate / l washing liquor were added. This corresponds to the usual dosage of a solid detergent mixture of around 3 g / l. In the subsequent rinse cycle, which was carried out with softened water, 0.4 g / l of a commercially available acidic rinse aid were dosed. After completion The cleaning performance was assessed throughout the entire wash program the detergent mixtures used. The individual evaluations were made after a Point system ranging from 0 to lo, with 0 points "without any noticeable cleaning effect" and 10 points meant complete removal of test soiling ". It resulted this resulted in a number of intermediate values that enabled a differentiated statement.
