Description
Die vorliegende Erfindung betrifft ein Verfahren zum Aufbringen von Duftstoffen auf Textilgut in einer Waschmaschine.The present invention relates to a method for applying fragrances on textile goods in a washing machine.
Bei der Textilwäsche, vor allem im Haushaltsbereich, ist es heute üblich, den Waschmitteln und Nachspülmitteln geringe Mengen an Parfüm zuzumischen, die dazu dienen, der Wasch- oder Spüllauge selbst, aber auch dem mit der Wasch- oder Spüllauge behandelten Textilgut einen angenehmen Duft zu verleihen. Man kann das Parfüm direkt in das Waschmittel einarbeiten oder es in einem zusätzlichen Schritt der Waschlauge zuführen.With textile laundry, especially in the household sector, it is common today add small amounts of perfume to the detergents and rinsing agents, which serve the washing or rinsing solution itself, but also the one with the Wash or rinse treated textile goods to give a pleasant fragrance. You can work the perfume directly into the detergent or it add the wash liquor in an additional step.
Die DE 39 11 363 beschreibt ein Verfahren zur Herstellung duftstoffhaltiger Wasch- oder Spüllaugen, in dem ein Duftstoff in Form einer Kapsel oder einer Tablette der Wasch- oder Spüllauge zugesetzt wird. Die Kapseln enthalten den Duftstoff zusammen mit einem Emulgator in flüssiger Form, während die Tabletten noch Füll- und Trägerstoffe, beispielsweise Natrium-Aluminium-Silikate oder Cyclodextrine enthalten. Die Tabletten oder Kapseln weisen ein Volumen von mehr als 1 cm3 auf und enthalten mindestens 1 g Duftstoff. Bevorzugt sind Tabletten oder Kapseln mit mehr als 2,5 g Duftstoff und einem Volumen von mindestens 5 cm3. Bei der Lagerung müssen derartige Tabletten oder Kapseln mit einer gas- und wasserdichten Umhüllungsschicht versehen werden, um die Inhaltsstoffe zu schützen. Weitergehende Einzelheiten über die Herstellung und die physikalischen Eigenschaften geeigneter Tabletten sind in dieser Druckschrift nicht enthalten.DE 39 11 363 describes a process for producing fragrance-containing washing or rinsing liquors, in which a fragrance in the form of a capsule or a tablet is added to the washing or rinsing liquor.

Parfümhaltige Tabletten, die sich zum Parfümieren einer Waschlauge verwenden lassen, werden auch in der deutschen Anmeldung 41 33 862 beschrieben. Die Tabletten enthalten zwischen 3 und 15 Gew.-% Parfümöl sowie als Trägermaterial für das Parfümöl zwischen 15 und 40 Gew.-% an Sorbit. Um ein gutes Auflösevermögen zu erzielen, werden 20 bis 70 Gew.-% eines Sprengmittels, bestehend aus einer Mischung aus Carbonat/Hydrogencarbonat und einer Säure, eingesetzt. Der hohe Anteil an Sprengmittel führt dazu, daß derartige Tabletten empfindlich gegenüber Luftfeuchtigkeit sind und entsprechend geschützt gelagert werden müssen.Perfume-containing tablets that are used to perfume a wash liquor leave, are also described in the German application 41 33 862. The tablets contain between 3 and 15% by weight of perfume oil as well as a carrier material for the perfume oil between 15 and 40 wt .-% of sorbitol. In order to achieve good resolving power, 20 to 70% by weight become one Disintegrant consisting of a mixture of carbonate / hydrogen carbonate and an acid. The high proportion of explosives means that such tablets are sensitive to air humidity and must be stored appropriately protected.
Nun sind aber höhere Parfümölanteile als in der obigen Schrift genannt durchaus wünschenswert, um kleinere Tabletten, die sich problemlos in die Einspülkammern herkömmlicher Waschmaschinen einfüllen lassen, zu erhalten. Bei einem herkömmlichen Tablettenpressverfahren besteht dann aber die Gefahr, daß die flüssige Komponente aus den Poren des Trägermaterials gedrückt wird und die Tabletten äußerlich feucht und schmierig werden.Now, however, higher perfume oil proportions than mentioned in the above document quite desirable to get smaller tablets that easily fit into the Have induction chambers filled in by conventional washing machines. With a conventional tablet pressing process, however, there is a risk that that the liquid component is pressed out of the pores of the carrier material the tablets become moist and greasy on the outside.

Zur Herstellung der erfindungsgemäß verwendeten Formkörper wird ein Gemisch eingesetzt, enthaltend eine Parfümzubereitung und Trägerstoffe sowie hydratisierte Substanzen, die ausgewählt sind aus der Gruppe der kristallwasserhaltigen Salze, vorzugsweise Alkalicarbonate, -hydrogencarbonate, Alkalisulfate und -hydrogensulfate sowie Acetate und Citrate. Diese Mischung enthält vorzugsweise 2 bis 20 und insbesondere 6 bis 12 Gew.-% gebundenes Wasser, bezogen auf das Gesamtgewicht der Mischung.A mixture is used to produce the moldings used according to the invention used, containing a perfume preparation and carriers as well hydrated substances selected from the group of salts containing water of crystallization, preferably alkali carbonates, bicarbonates, Alkali sulfates and hydrogen sulfates as well as acetates and citrates. This mixture preferably contains 2 to 20 and in particular 6 to 12 % By weight of bound water, based on the total weight of the mixture.
Zunächst werden die Einzelkomponenten, die im allgemeinen pulverförmig sind, aber auch granulare oder flüssige Komponenten enthalten können, vermischt, in die gewünschte Raumform gebracht und dann mit Mikrowellen bestrahlt.First, the individual components, which are generally powdered are, but can also contain granular or liquid components, mixed, brought into the desired spatial shape and then with microwaves irradiated.
Unter "Mikrowellen" wird im Rahmen der vorliegenden Erfindung der gesamte Frequenzbereich zwischen 3 und 300000 MHz verstanden, der also neben dem eigentlichen Mikrowellenbereich von oberhalb 300 MHz auch den Radiowellenbereich von 3 bis 300 MHz umfaßt. Hinsichtlich der Bestrahlungsbedingungen wird explizit auf WO 94/25563 verwiesen, z.B. können Mikrowellengeneratoren, die z.B. Strahlung einer Wellenlänge von 2450 MHz aussenden und eine Leistung von 250 Watt oder 1000 Watt aufweisen, verwendet werden.In the context of the present invention, “microwaves” includes the entire Understand the frequency range between 3 and 300000 MHz, which is next to the actual microwave range of above 300 MHz also the radio wave range from 3 to 300 MHz. Regarding the radiation conditions is explicitly referred to WO 94/25563, e.g. can microwave generators, e.g. Send out radiation with a wavelength of 2450 MHz and have a power of 250 watts or 1000 watts can be used.
Die Bestrahlungsdauer ist z.B. abhängig von der eingestellten Leistung des Mikrowellengerätes sowie von Gewicht und Zusammensetzung des zu bestrahlenden Gemisches. Im allgemeinen ist eine vom jeweiligen Gemisch abhängige Leistung von weniger als 1000 W/kg·h, vorzugsweise von 50 bis 400 W/kg·h und insbesondere von 100 bis 200 W/kg·h notwendig.The exposure time is e.g. depending on the set power of the Microwave device and the weight and composition of the radiation to be irradiated Mixture. Generally, one is dependent on the particular mixture Power less than 1000 W / kg · h, preferably from 50 to 400 W / kg · h and especially necessary from 100 to 200 W / kg · h.
Mit Hilfe dieser Technik lassen sich sogenannte Makrosolids herstellen. Dabei wird die Mischung der Ausgangsstoffe, die im Rahmen dieser Anmeldung als "Vorgemisch" bezeichnet wird, durch ein durch die Mikrowellenstrahlen bedingtes lokales Aufschmelzen/Sintern an den Kontaktstellen untereinander verbunden. Die Hohlräume, die zwischen den einzelnen Vorgemischbestandteilen vor der Bestrahlung mit Mikrowellen vorliegen, bewirken eine hohe Porosität der entstandenen Formkörper und tragen somit zur Verbesserung der Löseeigenschaften der Formkörper bei. Damit überhaupt ein lokales Sintern der Vorgemischbestandteile möglich ist, muß zumindest ein Teil von ihnen Sintereigenschaften an der Oberfläche besitzen. Dazu ist es erforderlich, daß die Vorgemischbestandteile selber oder deren Oberflächen genügend Wasser enthalten, so daß durch Erhitzung dieses Wassers eine Verschmelzung oder Vernetzung der Kontaktstellen an den Vorgemischbestandteilen erfolgt.So-called macrosolids can be produced using this technique. The mixture of starting materials used in this application is referred to as a "pre-mix" by a through the microwave rays Conditional local melting / sintering at the contact points with each other connected. The voids between the individual premix ingredients before exposure to microwaves cause a high Porosity of the resulting shaped bodies and thus contribute to improvement the dissolving properties of the moldings. A local at all Sintering of the premix components is possible, at least a part of they have sintering properties on the surface. To do this, it is necessary that the premix ingredients themselves or their surfaces are sufficient Contain water, so that by heating this water a fusion or networking of the contact points on the premix components he follows.
Im Rahmen der vorliegenden Erfindung ist der Begriff "Formkörper" nicht auf eine bestimmte Raumform beschränkt, obwohl im allgemeinen damit eine Tablette im herkömmlichen Sinne verstanden wird, d.h. ein zylinderförmiger Körper, wobei die Höhe des Zylinders kleiner ist als sein Durchmesser. Prinzipiell ist aber jede andere denkbare Raumform möglich, die dem Vorgemisch aufgrund eines äußeren Behältnisses aufgezwungen wird. Es ist auch möglich, die gewünschte Raumform dadurch zu erzielen, daß das Vorgemisch unter geringem Preßdruck leicht vorverpreßt wird und der so hergestellte - mechanisch nicht belastbare - Preßling anschließend bestrahlt wird.In the context of the present invention, the term “molded body” is not limited to a certain spatial form, although in general it is one Tablet is understood in the conventional sense, i.e. a cylindrical one Body, the height of the cylinder being less than its diameter. In principle, however, any other conceivable spatial form is possible, that of the premix is forced due to an outer container. It is also possible to achieve the desired spatial shape by the premix is slightly pre-pressed under low pressure and the - mechanically not resilient - compact is then irradiated.
In einer bevorzugten Ausführungsform weisen die erfindungsgemäß verwendeten Formkörper Kugelform auf, wobei der Durchmesser der Kugel zwischen 0,3 und 10 cm liegt, vorzugsweise zwischen 1,0 und 3 cm.In a preferred embodiment, the used according to the invention Shaped body spherical shape, the diameter of the ball between 0.3 and 10 cm, preferably between 1.0 and 3 cm.
Die im erfindungsgemäßen Verfahren eingesetzte Formkörper weisen eine Druckfestigkeit von mindestens 20 N/cm2 auf. Um sie gegebenenfalls zu teilen, können sie mit einer Bruchkante oder einer oder mehreren Bruchrillen versehen werden.The moldings used in the process according to the invention have a compressive strength of at least 20 N / cm 2 . In order to divide them if necessary, they can be provided with a break edge or one or more break grooves.
Die im erfindungsgemäßen Verfahren verwendeten Formkörper weisen einen Duftstoffgehalt von 8 bis 40 Gew.-%, vorzugsweise von 10 bis 25 Gew.-%, bezogen auf das Gesamtgewicht des Formkörpers, auf. The moldings used in the process according to the invention have a Fragrance content from 8 to 40% by weight, preferably from 10 to 25% by weight, based on the total weight of the molded body.
Bei den Parfümzubereitungen, die fest, aber vorzugsweise flüssig vorliegen, handelt es sich um teilweise komplexe Gemische aus verschiedenen chemischen Einzelverbindungen, den sogenannten Riechstoffen. Die Riechstoffe können aus den verschiedensten chemischen Klassen ausgewählt werden. Die Art der Riechstoffe hat dabei praktisch keinen Einfluß auf die physikalischen Eigenschaften des Formkörpers. Selbstverständlich umfaßt die vorliegende Erfindung auch solche Formkörper, die lediglich einen einzelnen Riechstoff enthalten.In the case of perfume preparations which are solid but preferably liquid, some of them are complex mixtures of different ones chemical single compounds, the so-called fragrances. The fragrances can be selected from a wide variety of chemical classes. The type of fragrance has practically no influence on the physical properties of the molded body. Includes, of course the present invention also includes such molded articles that have only one contain individual fragrance.
Man kann zwischen alkalistabilen und weniger alkalistabilen Riechstoffen unterscheiden. Alkalistabile Riechstoffe sind z.B. Linalool, Geraniol, Acetophenon, Lilial, Geranonitril, Dihydromyrcenol, o-tert-Butylcyclohexylacetat, Anisaldehyd, Tetrahydrolinalool, Citronellol, Cyclohexylsalicylat, Phenylethylalkohol, Benzophenon, Rosenoxid, Methylbenzoat, α-Hexyl-zimtaldehyd; zu den weniger alkalistabilen Riechstoffen gehören Vetiverylacetat, δ-Dodecalacton, Allylamylglycolat, Hydroxycitronellal, Benzylacetat, Amylbutyrat. Bei Verwendung von weniger alkalistabilen Riechstoffen ist darauf zu achten, daß der verwendete Trägerstoff über keine zu hohe Alkalität verfügt. Gegebenenfalls kann auch mit schwach sauren Zuschlagstoffen, z.B. NaHSO4, Na2HPO4, NaH2PO4 oder Citronensäure, der pH-Wert abgesenkt werden.One can distinguish between alkali-stable and less alkali-stable fragrances. Alkali-stable odoriferous substances are, for example, linalool, geraniol, acetophenone, lilial, geranonitrile, dihydromyrcenol, o-tert-butylcyclohexyl acetate, anisaldehyde, tetrahydrolinalool, citronellol, cyclohexyl salicylate, phenylethyl alcohol, benzophenone, rose oxide, methyl benzylate; The less alkali-stable fragrances include vetiveryl acetate, δ-dodecalactone, allylamyl glycolate, hydroxycitronellal, benzyl acetate, amyl butyrate. When using less alkali-stable fragrances, it must be ensured that the carrier used does not have too high an alkalinity. If necessary, the pH can also be lowered using weakly acidic additives, for example NaHSO 4 , Na 2 HPO 4 , NaH 2 PO 4 or citric acid.
Um bei der Auswahl der Riechstoffe möglichst wenig Einschränkungen zu unterliegen, sollte der pH-Wert einer 1 Gew.-%igen wäßrigen Lösung der fertigen erfindungsgemäß verwendeten Formkörper idealerweise bei 3 bis 12, vorzugsweise bei 5,5 bis 8,5 liegen.In order to be subject to as few restrictions as possible when selecting fragrances, should the pH of a 1 wt .-% aqueous solution of the finished Moldings used according to the invention ideally at 3 to 12, are preferably 5.5 to 8.5.
Die erfindungsgemäß verwendeten Duftstoffkörper können weiterhin Tenside in Mengen bis zu 40 Gew.-%, vorzugsweise von 0,5 bis 15 Gew.-%, bezogen auf das Gesamtgewicht des Formkörpers, enthalten. Damit wird eine bessere Benetzung des zu beduftenden Textilguts erreicht.The fragrance bodies used according to the invention can also contain surfactants in amounts up to 40% by weight, preferably from 0.5 to 15% by weight on the total weight of the molded body. It will be a better one Wetting of the scented textile goods achieved.
