Die Anmeldung betrifft benzotriazolhaltige, granulare Komponenten für den Einsatz in MGSM und Verfahren zu dessen HerstellungThe application relates to granular components containing benzotriazole for the Use in MGSM and process for its production
Granulare Reinigungsnsmittel für MGSM sind bekannt, weil sie gut dosierbar schütt- und rieselfähig, lagerstabil und optisch ansprechend für den Verbraucher sind.Granular cleaning agents for MGSM are known because they are easy to dose pourable and pourable, stable in storage and visually appealing to the consumer are.
Benzotriazol ist eine Korrosionsschutzkomponente, die in aktivsauerstoffhaltigen Reinigern heute weit verbreitet ist. Die chemische Stabilität in diesen Systemen ist aber nur bedingt gegeben, da Benzotriazol von Oxidationsmitteln leicht abgebaut wird. Dabei entstehen vor allem bei längerer Lagerung z.B. gelb gefärbte und unangenehm riechende Oxidationsprodukte, die zur Verfärbung des Reinigers, dem Verlust der Korrosionsschutzwirkung und zur mangelnden Akzeptanz des Produktes beim Verbraucher führen.Benzotriazole is a corrosion protection component that in active oxygen Cleaners is widely used today. The chemical stability in these systems is only given to a limited extent, since benzotriazole is easily oxidized is broken down. This is especially the case with longer storage, e.g. yellow colored and unpleasant smelling oxidation products that discolor the Cleaner, the loss of corrosion protection and the lack of Acceptance of the product by the consumer.

Wichtig dabei ist, daß der extrudierbare Feststoff so gewählt ist, daß das Granulat in 20°C warmen Wasser innerhalb 10 Minuten, bevorzugt innerhalb 2 Minuten aufgelöst wird. Das beschriebene Verfahren beansprucht alle geeigneten Prozesse, die Arbeit auf die Mixtur des organischen extrudierbaren Feststoffs ausüben. Beispielhaft genannt für solche geeigneten Prozesse sind Mahlen, Pelletieren, Extrudieren, Stampfen und Pressen. Die Patentschrift deutet an, daß es durch die Verwendung von organischen Feststoffen in der Regel in Waschmitteln, die die erfindungsgemäßen Granulate enthalten, nicht zur Segregation von verschiedenartigen Teilchen kommen wird.From the British patent GB 1 400 444 (Unilever) granules are known which contain an organic extrudable solid, uniformly dispersed, which is selected from the group of corrosion inhibitors, such as benzotriazoles, bismethylene benzotriazoles, ethoxylated phosphate esters, oximes and hydroxamates and which are suitable for incorporation into detergent powder compositions. It is important that the extrudable solid is selected so that the granules are dissolved in water at 20 ° C. within 10 minutes, preferably within 2 minutes. The method described claims everyone suitable Processes that work on the mixture of organic extrudable solid. Examples of such suitable processes are grinding, pelleting, extruding, tamping and pressing. The patent indicates that the use of organic solids, as a rule in detergents which contain the granules according to the invention, will not result in segregation of different types of particles.
Die WO 95/1416 (Procter & Gamble) beschreibt eine Bleichzusammensetzung, die für das maschinelle Geschirrspülen geeignet ist, die eine Sauerstoffbleichmittel, Paraffinöl und eine Benzotriazolkomponente enthält, wobei die Gesamtkomponente zum Einsatz in Waschmitteln gedacht ist. Die Komponenten können als Pulver, Granulate, Pasten, Flüssigkeiten, Gele, Tabletten vorliegen, wobei granulare Zubereitungsformen bevorzugt sind. Dichten von mindestens 650 g/l oder üblicherweise mindestens 700 g/l und bevorzugt zwischen 800 und 1200 g/l sowie Teilchengrößen, die so verteilt sind, daß nicht mehr als 5% der Partikel größer als 1,4 mm im Durchmesser und nicht mehr als 5% der Partikel weniger als 0,15 mm im Durchmesser betragen, sind bevorzugt. In der Anmeldung werden mehrere Verfahren beschrieben, diese Granulate zu erhalten. Ein bevorzugter Prozeß zur Herstellung der Verbindung beinhaltet das Vormischen von Paraffinöl und einem Dispersionsmittel, wobei dieses Vorgemisch auf den Rest der Zusammensetzung aufgesprüht wird. Das Dispersionsmittel ist vorteilhafterweise nichtionisches Tensid. Aber auch eine Methode des Aufsprühens von Paraffinöl und Dispersionsmittel auf das Bleichmittel, mit der damit verbundenen Reduzierung der Lösegeschwindigkeit des Bleichmittels in Wasser, dem sogenannten "coaten", ist bevorzugt, wobei die gecoateten Bleichpartikel danach in einem Trockenmischprozess mit dem Rest der Zusammensetzung vermengt wird. Ebenfalls beschrieben ist die Kompaktierung des Bleichmittels bevor man es mit den restlichen Inhaltsstoffen der Zusammensetzung trocken vermischt. Es gibt keine Anweisung wie Benzotriazol homogen in eine gut rieselfähige Geschirrspülmittelkomponente eingearbeitet werden soll. WO 95/1416 (Procter & Gamble) describes a bleaching composition which is suitable for automatic dishwashing, the one Contains oxygen bleach, paraffin oil and a benzotriazole component, the entire component is intended for use in detergents. The Components can be powder, granules, pastes, liquids, gels, Tablets are present, with granular preparation forms being preferred. Densities of at least 650 g / l or usually at least 700 g / l and preferably between 800 and 1200 g / l and particle sizes which are distributed in such a way that no more than 5% of the particles are larger than 1.4 mm in diameter and not more than 5% of the particles are less than 0.15 mm in diameter prefers. Several procedures are described in the application, these To obtain granules. A preferred process for making the connection involves premixing paraffin oil and a dispersant, where this premix is sprayed onto the rest of the composition. The The dispersant is advantageously nonionic surfactant. But also one Method of spraying paraffin oil and dispersant on the Bleach, with the associated reduction in dissolving speed of the bleaching agent in water, the so-called "coating", is preferred, the coated bleach particles thereafter in a dry mixing process with the rest the composition is mixed. The is also described Compact the bleach before mixing it with the rest of the ingredients the composition mixed dry. There is no instruction how Benzotriazole homogeneously in a free-flowing dishwasher detergent component should be incorporated.
Die Patentschrift US 4 321 166 (Procter & Gamble) beschreibt builderfreie, flüssige Waschmittelsysteme, die als Korrosionsinhibitor eine Mischung aus aromatischen Triazolen und oligomeren olefinischen Fettsäuren enthalten. Das Antikorrosionsmittel soll hierbei die Verfärbung der metallenen Waschkörbe in automatischen Waschmaschinen und die Verfärbung von Fasern, die in Kontakt mit den Waschkörben kommen, verhindern. In der Schrift ist kein Hinweis darauf gegeben, wie organische redoxaktive Substanzen homogen in Bleichmittelkomponenten eingearbeitet werden können, und wie Silberschutz durch diese Komponenten erreicht werden kann.The US Pat. No. 4,321,166 (Procter & Gamble) describes builder-free, liquid detergent systems that act as a corrosion inhibitor aromatic triazoles and oligomeric olefinic fatty acids. The Anti-corrosion agents are said to discolor the metal wash baskets in automatic washing machines and the discoloration of fibers in contact prevent coming with the wash baskets. There is no reference to this in the scriptures given how organic redox-active substances homogeneous in Bleach components can be incorporated, and like silver protection can be achieved through these components.
Keine der oben genannten Patentschriften zeigt aber, wie eine Benzotriazol enthaltende granulare gut rieselförmige Komponente herstellbar ist. Das Problem liegt u.a. darin, daß Benzotriazol enthaltende Mischungen, die nach den üblichen Methoden der Granulation, wie zum Beispiel der Verwendung von Flüssigkeiten zum Kornaufbau, hergestellt werden, schlecht zu verarbeiten sind, da das Gemisch zum Verbacken neigt und daher schlecht rieselfähig ist. Die physikalische Eigenschaft der Rieselfähigkeit der Komponente sollte über einen langen Zeitraum stabil gehalten werden. Aber auch die chemische Stabilität von Benzotriazol enthaltenden Komponenten kann mit den Erkenntnissen der obigen Schriften nicht gelöst werden. Diese Eigenschaft wird um so wichtiger vor dem Hintergrund der Einarbeitung dieser Komponenten in Maschinengeschirrspülmittel. Hier sind die Eigenschaften der physikalischen und chemischen Stabilität der granularen Komponenten besonders wünschenswert. Besonders Benzotriazol soll bei Anwesenheit von oxidativ wirksamen Komponenten stabil bleiben, damit es noch als Silberschutzmittel wirksam sein kann.However, none of the above-mentioned patents shows how a benzotriazole containing granular well poured component can be produced. The problem lies among other things in that mixtures containing benzotriazole, according to the usual Methods of granulation, such as the use of liquids to build grain, are difficult to process, because that Mixture tends to cake and is therefore difficult to pour. The The physical property of the pourability of the component should have one be kept stable for a long period of time. But also the chemical stability of Components containing benzotriazole can use the knowledge of the above Fonts cannot be resolved. This property becomes all the more important before Background to the incorporation of these components in Dishwasher detergent. Here are the characteristics of the physical and chemical stability of the granular components is particularly desirable. Benzotriazole in particular is said to be oxidatively active in the presence of Components remain stable so that it can still be effective as a silver protection agent can.
Aufgabe war ein gut rieselfähiges, lagerstabiles, homogenes Granulat verfügbar zu machen, welches Benzotriazol enthält und als Silberschutz für das maschinelle Geschirrspülen geeignet ist. Das im Granulat enthaltende Benzotriazol sollte gegen oxidativen Angriff geschützt werden.
