Description

"Waschmittel-Formkörper" "Detergent tablets"
Die vorliegende Erfindung betrifft Waschmittel-Formkörper in pastöser, formstabiler Form, wobei die Formkörper eine für einen Waschvorgang ausreichende Menge an Wirkstoffen enthalten.The present invention relates to detergent tablets in pasty, dimensionally stable form, the tablets containing a sufficient amount of active ingredients for a washing process.
Portionspackungen für Waschmittel oder Waschhilfsmittel, im fol¬ genden Waschmittel genannt, bieten gegenüber nichtportionierten Waschmitteln den Vorteil der einfachen und genauen Dosierung. Be¬ kannte Vorschläge für Waschmittel-Portionspackungen betreffen ent¬ weder wasserdurchlässige, wasserunlösliche, meist beuteiförmige Verpackungen für pulverförmige Waschmittel. Andere Ausführungs¬ formen betreffen wasserundurchlässige Verpackungsmaterialien, die entweder in Wasser löslich sind oder bei denen daraus hergestellte Verpackungen für pulverförmige oder flüssige Waschmittel sich in Wasser öffnen und dabei den Inhalt an die Waschflotte abgeben. Pulverförmige Waschmittel weisen dabei den Nachteil auf, daß sie, ohne ihre pulverförmigen Eigenschaften zu verlieren, nur geringe Mengen an flüssigen Bestandteilen, beispielsweise nichtionische Tenside enthalten können, was für manche Anwendungszwecke, bei¬ spielsweise für die Entfernung fettiger und öliger Verschmutzungen von Nachteil ist. Andererseits ist der Anteil an unlöslichen Waschmittelbestandteilen, beispielsweise an dem als Phosphat¬ ersatzstoff in großen Mengen in Waschmitteln eingesetzten Zeolith A, wegen dessen Neigung zur Sedimentation in flüssigen Waschmitteln begrenzt. Außerdem können in flüssigen Waschmitteln miteinander nicht- oder schlechtverträgliche Waschmittelbestand¬ teile in Wechselwirkung, treten und sich in ihrer Wirkung gegen¬ seitig beeinträchtigen.Portion packs for detergents or washing aids, hereinafter called detergents, offer the advantage of simple and precise dosing compared to non-portioned detergents. Known suggestions for detergent portion packs relate either to water-permeable, water-insoluble, mostly bag-shaped packaging for powdered detergents. Other embodiments relate to water-impermeable packaging materials which are either soluble in water or in which packaging for powdery or liquid detergents produced therefrom opens in water and thereby releases the contents to the washing liquor. Powdery detergents have the disadvantage that, without losing their powdery properties, they can contain only small amounts of liquid constituents, for example nonionic surfactants, which is for some applications, for example for the removal of greasy and oily soiling is a disadvantage. On the other hand, the proportion of insoluble detergent constituents, for example zeolite A used as a phosphate substitute in large quantities in detergents, is limited because of its tendency to sediment in liquid detergents. In addition, detergent constituents which are incompatible or poorly compatible with one another can interact with one another in liquid detergents, and their action can impair one another.
Die geschilderten Nachteile von Portionspackungen für pulverför¬ mige oder flüssige Waschmittel zu vermeiden oder zu verringern, ist Aufgabe der vorliegenden Erfindung. Gegenstand der vorliegen¬ den Erfindung ist daher ein Waschmittel-Formkörper, der dadurch gekennzeichnet ist, daß er eine bis 40 °C formstabile Konsistenz hat und daß er bis zum Gebrauch in einer den Formkörper formgebend umhüllenden Hülse herausdrückbar enthalten ist. Die Hülse stellt also die Verpackung für den pastenförmigen Waschmittel-Formkörper dar, aus dem der Waschmittelbenutzer die für einen Waschvorgang erforderliche Menge an Waschmittel durch Herausdrücken des Form¬ körpers entnehmen kann. Pastenförmige Waschmittel sind hinsicht¬ lich der Auswahl ihrer Inhaltsstoffe den geringsten Einschrän¬ kungen unterworfen, so daß pastenförmige Waschmittel ihrem Verwen¬ dungszweck weitgehend oder vollständig angepaßt werden können.The object of the present invention is to avoid or reduce the described disadvantages of portion packs for powdery or liquid detergents. The present invention therefore relates to a detergent tablet, which is characterized in that it has a shape-stable consistency of up to 40 ° C. and that it is contained in a sleeve that can be pressed out to form a mold, until it is used. The sleeve thus represents the packaging for the pasty detergent shaped body, from which the detergent user can remove the amount of detergent required for a washing process by pressing out the shaped body. Paste-like detergents are subject to the slightest restrictions with regard to the selection of their ingredients, so that paste-like detergents can be largely or completely adapted to their intended use.
Obgleich es denkbar wäre, daß man für einen Waschvorgang den In¬ halt mehrerer solcher Hülsen oder nur einen Teil des Inhalts einer besonders großen Hülse verwendet, ist es vorteilhaft, daß man die Größe des Waschmittel-Formkörpers in der Hülse so bemißt, daß er für einen Waschvorgang eine genau abgestimmte Menge Waschmittel¬ bestandteile enthält. Eine bevorzugte Ausführungsform der vorlie¬ genden Erfindung ist daher ein Waschmittel-Formkörper, der eine für einen Waschvorgang ausreichende Menge an Textilien reinigenden und pflegenden Wirkstoffen sowie gegebenenfalls Hilfsstoffen ent¬ hält.Although it would be conceivable to use the content of several such sleeves or only part of the contents of a particularly large sleeve for a washing process, it is advantageous to measure the size of the detergent tablet in the sleeve so that it is suitable for a washing process contains a precisely coordinated amount of detergent ingredients. A preferred embodiment of the present invention is therefore a detergent tablet which cleans a sufficient amount of textiles for a washing process and caring active ingredients and optionally auxiliary substances.
Durch den Gegenstand der vorliegenden Erfindung ist es auch mög¬ lich, Waschmittel-Inhaltsstoffe, die sich gegenseitig ungünstig beeinflussen, wenn sie miteinander in Kontakt kommen, räumlich getrennt voneinander in. der Hülse des Formkörpers anzuordnen. Eine derartige unerwünschte Wechselwirkung findet beispielsweise zwischen den in Waschmitteln üblicherweise vorhandenen Perverbin¬ dungen und dem Phosphatersatzstoff Zeolith A statt. Eine besonders ' vorteilhafte Ausführungsform der vorliegenden Erfindung ist daher ein Waschmittel-Formkörper, der aus zwei oder mehr voneinander ge¬ trennt angeordneten Schichten besteht. Diese können beispielsweise beim Befüllen der Hülse übereinander angeordnet werden, wobei sie sich wegen der formstabilen Konsistenz des Waschmittel-Formkörpers nicht miteinander vermischen. Falls auch eine Berührung der beiden Schichten an der Grenzfläche vermieden werden muß, kann man die voneinander getrennt zu haltenden Schichten auch durch undurch¬ lässige, inerte Zwischenschichten voneinander trennen. Diese Trennschichten können entweder aus ausgewählten Waschmittel-In¬ haltsstoffen selbst oder aus dünnen Folien bestehen, die zwischen den voneinander getrennt zu haltenden Schichten des Formkörpers angeordnet werden. Die Folien können dabei wasserunlöslich oder vorzugsweise wasserlöslich sein. Eine wasserlösliche Ausführungs¬ form stellen beispielsweise Folien aus Polyvinylalkohol oder was¬ serlöslichen Polyacrylaten dar. Auf diese Weise ist es möglich, daß bei einem Formkörper, der aus zwei voneinander getrennten Schichten besteht, die eine Schicht bleichende Wirkstoffe enthält, während die andere Schicht frei von bleichenden Wirkstoffen ist. Eine weitere Ausführungsform des Erfindungsgegenstandes ist daher ein Waschmittel-Formkörper, der aus zwei voneinander getrennten Schichten besteht, von denen eine Schicht bleichende Wirkstoffe enthält, und die andere Schicht frei von bleichenden Wirkstoffen ist. Die von bleichenden Wirkstoffen freie Schicht kann dann ge- wünschtenfalls solche Waschmittel-Inhaltsstoffe enthalten, die mit den bleichenden Wirkstoffen in unerwünschte Wechselwirkungen tre¬ ten können. Beispielsweise sind dies Waschmittel-Builder. Ein weiterer Gegenstand der vorliegenden Anmeldung ist daher ein Waschmittel-Formkörper, . der aus zwei voneinander getrennten Schichten besteht, von denen eine Schicht bleichende Wirkstoffe enthält und die andere Schicht Waschmittel-Builder enthält.The subject matter of the present invention also makes it possible to spatially separate detergent ingredients which adversely affect one another when they come into contact with one another . to arrange the sleeve of the molded body. Such an undesirable interaction takes place, for example, between the perverbind¬ usually present in detergents and the phosphate substitute Zeolite A. A particularly 'advantageous embodiment of the present invention therefore, there is a detergent shaped body of two or more ge separates layers arranged. These can be arranged one above the other, for example, when the sleeve is being filled, but do not mix with one another because of the dimensionally stable consistency of the detergent tablet. If contact between the two layers at the interface must also be avoided, the layers to be kept separate from one another can also be separated from one another by impermeable, inert intermediate layers. These separating layers can either consist of selected detergent ingredients themselves or of thin foils which are arranged between the layers of the shaped body to be kept separate from one another. The films can be water-insoluble or preferably water-soluble. Films made of polyvinyl alcohol or water-soluble polyacrylates, for example, represent a water-soluble embodiment. In this way, it is possible for a molded article which consists of two separate layers to contain one layer of bleaching active ingredients while the other layer is free of bleaching agents. A further embodiment of the subject matter of the invention is therefore a detergent tablet which consists of two separate layers, one layer of which contains bleaching agents contains, and the other layer is free of bleaching agents. If desired, the layer free of bleaching agents can then contain detergent ingredients that can interact with the bleaching agents in undesirable interactions. For example, these are detergent builders. Another object of the present application is therefore a detergent tablet. which consists of two separate layers, one layer containing bleaching agents and the other layer containing detergent builder.
Je nach der Art der Zusammensetzung des Waschmittel-Formkörpers und abhängig von dem Material der formgebenden Hülse, kann das Herausdrücken des Formkörpers leicht oder weniger leicht mittels Fingerdruck erfolgen. In Fällen, wo dies weniger leicht möglich ist oder wenn ein Hautkontakt mit den Waschmittel-Inhaltsstoffen vermieden werden sollte, empfiehlt sich als ein Hilfsmittel die Benutzung einer Druckplatte. Eine bevorzugte Ausführungsform des Erfindungsgegenstandes stellt daher einen Waschmittel-Formkörper dar, der mittels einer dem Querschnitt der Hülse entsprechenden Druckplatte herausdrückbar in der Hülse enthalten ist. Diese Druckplatte wirkt beim Herausdrücken des Formkörpers ähnlich wie ein Kolben in einem Zylinder.Depending on the type of composition of the detergent molding and depending on the material of the shaping sleeve, the molding can be pressed out easily or less easily by finger pressure. In cases where this is less easy or if skin contact with the detergent ingredients should be avoided, the use of a pressure plate is recommended as an aid. A preferred embodiment of the subject matter of the invention therefore represents a detergent shaped body which is contained in the sleeve so that it can be pressed out by means of a pressure plate corresponding to the cross section of the sleeve. This pressure plate acts like a piston in a cylinder when the molded body is pressed out.
Durch den Gegenstand der vorliegenden Erfindung ist es möglich, pastenförmige Waschmittel mit einem hohen Gehalt an waschwirksamen Inhaltsstoffen so zu dosieren, daß gerade die für einen Wasch or¬ gang erforderliche Menge an Waschmittel der Waschflotte zugesetzt wird. Dabei ist es ein besonderer Vorteil, daß man miteinander nicht- oder schlechtverträgliche Waschmittel-Inhaltsstoffe so von¬ einander getrennt in dem Waschmittel-Formkörper anordnen kann, daß die ungünstige Wechselwirkung zuverlässig vermieden wird. BeispieleThe object of the present invention makes it possible to meter paste-like detergents with a high content of detergent ingredients in such a way that just the amount of detergent required for a wash is added to the wash liquor. It is a particular advantage that detergent ingredients which are incompatible or poorly compatible with one another can be arranged separately from one another in the shaped detergent body in such a way that the unfavorable interaction is reliably avoided. Examples
Die Bestandteile eines pastenförmigen Universalwaschmittels wurden so auf zwei Pasten A und B aufgeteilt, daß die Phase A u. a. den Waschmittel-Builder, aber kein Bleichmittel, und die Paste B das Bleichmittel, aber keinen Waschmittelbuilder ent¬ hielt. Beide Pasten sind bis etwa 40 °C formstabil, die Zu¬ sammensetzung der beiden Pasten geht aus der folgenden Tabelle 1) hervor:The components of a pasty universal detergent were divided into two pastes A and B so that phase A u. a. the detergent builder, but no bleach, and paste B the bleach, but no detergent builder. Both pastes are dimensionally stable up to about 40 ° C, the composition of the two pastes is shown in the following table 1):
Tabelle 1Table 1
Fortsetzung Tabelle 1 Continuation of table 1
Die Herstellung beider Pasten erfolgte, indem man bei 70 bis 75 °C in dem nichtionischen Tensid und dem Polyethylenglykol die Seife und das Alkylbenzolsulfonat-Natrium einrührte. Im Fall der Paste A wurde dann Zeolith A Farbstoff und Wasser zugegeben und auf ca. 45 °C abgekühlt; bei der Herstellung beider Pasten wurden bei dieser Temperatur die restlichen Rezepturbestandteile zugegeben und je 50 g beider Pasten in eine zylinderförmige Hülse abgefüllt, wobei man die Paste A von Paste B durch Einlegen einer Folie aus Polyvinylalkohol voneinander trennte. An einem Ende wurde die Hülse mit einer dem Querschnitt der Hülse angepaßten Platte aus Kunststoff, die als Kolben beim Ausdrücken des Waschmittel-Formkörpers ver¬ wendet werden kann, verschlossen. Der beschriebene Waschmittel- Formkörper besteht praktisch vollständig aus waschwirksamen Wirk¬ stoffen und ist in der Waschflotte vollständig löslich. Dadurch, daß die Paste A von Paste B getrennt voneinander in der Hülse an¬ geordnet ist, ist eine praktisch beliebig lange Lagerung des Waschmittel-Formkörpers gewährleistet. Both pastes were prepared by stirring the soap and the alkylbenzenesulfonate sodium at 70 to 75 ° C. in the nonionic surfactant and the polyethylene glycol. In the case of paste A, zeolite A dye and water were then added and the mixture was cooled to about 45 ° C. in the production of both pastes, the remaining formulation components were added at this temperature and 50 g of both pastes were filled into a cylindrical sleeve, wherein paste A was separated from paste B by inserting a film of polyvinyl alcohol. At one end, the sleeve was closed with a plastic plate which was adapted to the cross section of the sleeve and which can be used as a piston when pressing out the shaped detergent body. The detergent tablet described consists practically entirely of detergent active substances and is completely soluble in the washing liquor. The fact that paste A and paste B are arranged separately from one another in the sleeve ensures that the detergent tablet is stored for practically any length of time.
