Es ist bekannt, synthetische Tenside - ähnlich wie die aus Fettsäureseifen erzeugten Seifen - durch Kneten, Pilieren, Strangpressen, Extrudieren, Schneiden und Stückpressen in eine für den Transport oder für die Anwendung geeignete Form zu bringen und auf diese Weise Nudeln, Granulate, Riegel und handliche Toilettenseifen-Stücke zu erzeugen.It is known to use synthetic surfactants - similar to those made from fatty acid soaps Soaps - by kneading, piling, extruding, extruding, cutting and bar pressing to bring into a form suitable for transport or use and on in this way to produce pasta, granules, bars and handy toilet soap pieces.

Die bekannten schaumstarken anionischen Tenside werden zu diesem Zweck üblicherweise mit Plastifikatoren, Füll- und Streckmitteln vermischt, die eine leichtere Verformung möglich machen und eine bessere Formstabilität bewirken.The well-known high-foaming anionic surfactants are used for this purpose usually mixed with plasticizers, fillers and extenders, which is a lighter Make deformation possible and bring about better dimensional stability.

Leider haben viele dieser Stoffe eine nachteilige Wirkung auf das Schäumvermögen der Syndetmassen, insbesondere das Anschäumverhalten, die Schaummenge, Schaumstabilität und Schaumqualität von Syndetmassen sind oft unbefriedigend.Unfortunately, many of these substances have an adverse effect on the foaming power of the Syndet materials, especially the foaming behavior, the amount of foam, foam stability and foam quality of syndet masses are often unsatisfactory.

Auch Wasser kann in den erfindungsgemäßen Syndetmassen enthalten sein, sein Anteil sollte jedoch unter 10 Gew.-% der Syndetmasse bleiben. Bevorzugt sind etwa 5 - 10 Gew.-% Wasser in der Syndetmasse enthalten.Water can also be present in the syndet compositions according to the invention, its proportion however, should remain below 10% by weight of the syndet mass. About 5-10 are preferred % By weight of water contained in the syndet mass.

In einer besonders bevorzugten Ausführungsform enthalten die erfindungsgemäßen Syndetmassen :

  • 30 - 40 Gew.-% anionischer Tenside aus der Gruppe der Acylisethionat-Salze, der Sulfobemsteinsäuremonoalkylester-Salze oder deren Gemische

  • 10 - 30 wt .-% talc and
  • 5 - 10% by weight water.

    • Die Herstellung der erfindungsgemäßen geformten Syndetmassen kann in der für solche Produkte üblichen Weise erfolgen, wobei die erfindungsgemäße Kombination von synthetischen Tensiden und Talkum eine besonders gut formbare, in der Wärme plastische und nach dem Erkalten harte Masse ergibt. Die geformten Produkte weisen eine glatte Oberfläche auf, die auch nach dem Benetzen mit Wasser wieder trocknet, ohne weich zu werden.The production of the shaped syndet masses according to the invention can be done for such Products take place in the usual way, the combination of synthetic surfactants and talc are particularly easy to form in the heat plastic and hard mass after cooling. The molded products have a smooth surface that dries again even after wetting with water to become soft.

    Übliche Verfahren zum Mischen bzw. Homogenisieren, Kneten und ggf. Pilieren, Strangpressen, ggf. Pelletieren, Extrudieren, Schneiden und Stückpressen, wie sie z.B. in JAOCS, Vol. 59, No. 10 (October 1982), 442 - 448 beschrieben sind, können auch für die Herstellung der erfindungsgemäßen Syndet-Seifenmassen eingesetzt werden.Usual methods for mixing or homogenizing, kneading and optionally polishing, Extrusion, possibly pelleting, extrusion, cutting and piece pressing, such as those e.g. in JAOCS, Vol. 59, No. 10 (October 1982), 442-448 can also be used for Production of the Syndet soap compositions according to the invention can be used.

    Für die Herstellung von Toiletten-Syndetstücken auf Basis der erfindungsgemäßen Syndetmasse hat sich folgende Arbeitsweise bewährt:For the production of toilet syndet pieces based on the invention The following working method has proven itself:

    Die schmelzbaren Komponenten, z.B. die Fettsäure, der Fettalkohol, das Alkyl-(oligo)-glucosid und die schmelzbaren oder flüssigen Plastifikatoren werden bei einer Temperatur im Bereich von 60 - 90°C in einem heizbaren Kneter oder Mischer aufgeschmolzen und gemischt. Dann erfolgt die Zugabe des Aniontensids, z.B. des C12-C18-Acylisethionat-Salzes, ggf. des Sulfosuccinats und der Stärke und anderer bei 60 - 90°C nicht schmelzbarer Komponenten und ggf. des Wassers, sowie eine Vermischung oder Verknetung des Ansatzes bei einer Temperatur von ca. 70°C.The meltable components, for example the fatty acid, the fatty alcohol, the alkyl (oligo) glucoside and the meltable or liquid plasticizers, are melted and mixed at a temperature in the range from 60 to 90 ° C. in a heatable kneader or mixer. Then the anionic surfactant, for example the C 12 -C 18 -acyl isethionate salt, optionally the sulfosuccinate and the starch and other components which cannot be melted at 60-90 ° C. and, if appropriate, the water, are added, and the mixture is mixed or kneaded at a temperature of approx. 70 ° C.

    Eine weitere Homogenisierung läßt sich dadurch erreichen, daß die Masse mehrfach durch Siebe gepreßt und schließlich bei einer Kopftemperatur von 40 bis 70°C zu einem Strang verpreßt wird, der in gleichmäßige Stücke geschnitten wird. Die Stücke können schießlich in einer Formpresse in die endgültige Form gebracht werden. A further homogenization can be achieved in that the mass is repeated pressed through sieves and finally at a head temperature of 40 to 70 ° C Strand is pressed, which is cut into uniform pieces. The pieces can are finally brought into the final shape in a molding press.

    Anstelle der Strangpresse kann auch eine Extrusion durch eine Lochplatte erfolgen, dabei werden Nudeln oder Nadeln erhalten- oder, wenn der Lochplatte Messer nachgeschaltet sind, Granulate gebildet.Instead of the extrusion press, extrusion through a perforated plate can also take place noodles or needles are obtained or if the perforated plate is followed by a knife are formed, granules.
