Die Erfindung betrifft eine geformte Syndet-Seifenmasse mit einem Gehalt von wenigstens 50 Gew -% synthetischer Tenside und wenigstens 10 Gew.-% nichttensidischen Hilfsstoffen.The invention relates to a shaped Syndet soap composition with a content of at least 50% by weight of synthetic surfactants and at least 10% by weight of non-surfactant auxiliaries.
Es ist bekannt, synthetische Tenside ähnlich wie die aus Fettsäuren erzeugten Seifen durch Kneten, Pilieren, Strangpressen, Extrudieren, Schneiden und Stückpressen in eine geeignete Form für den Transport und für die Anwendung zu bringen. Auf diese Weise lassen sich Nudeln, Granulate, Riegel und handliche Toilettenseifen-Stücke erzeugen.It is known to bring synthetic surfactants, like the soaps produced from fatty acids, into a suitable form for transport and use by kneading, piling, extruding, extruding, cutting and bar-pressing. In this way, pasta, granules, bars and handy toilet soap pieces can be produced.
Die durch Veresterung von Fettsäuren mit den Salzen der 2-Hydroxyethan-sulfonsäuren (Isethionsäure) zugänglichen Acylisethionate sind als Komponenten solcher Syndet- Seifenmassen seit langem bekannt. Die geringe Plastizität dieser Tenside bedingt erhebliche Probleme bei der Verarbeitung zu geformten Produkten. Darüber hinaus ist das Schaum verhalten der Acylisethionate unbefriedigend, sie haben eine geringe Schaumkonsistenz und ein schwaches Anschaumverhalten. Es hat daher nicht an Versuchen gefehlt, durch Zusätze die Verarbeitungs- und Anwendungseigenschaften der Acylisethionate zu verbessern und für die Herstellung geformter Syndet-Seifen geeigneter zu machen.The acyl isethionates obtainable by esterification of fatty acids with the salts of 2-hydroxyethanesulfonic acids (isethionic acid) have long been known as components of such Syndet soap compositions. The low plasticity of these surfactants causes considerable problems when processing them into shaped products. In addition, the foam behavior of the acyl isethionates is unsatisfactory, they have a low foam consistency and a poor foaming behavior. There has therefore been no lack of attempts to improve the processing and application properties of the acyl isethionates by additives and to make them more suitable for the production of shaped Syndet soaps.
Alkyl-(oligo)-glycoside sind als Komponenten in Stückseifen auf Basis von Fettsäure-Seife schon mehrfach beschrieben, z.B. in DE-A-43 37 031 und in DE-A-43 31 297. Ihr Einsatz in Seifenmassen auf Basis von Alkylsulfaten und Sulfobemsteinsäureester-Salzen ist von G. Proserpio und G. Vianello in Rivista Italiana Essenze Profumi ...

Aus DE-A-31 29 280 war ein Verfahren zur Herstellung von Detergensstücken bekannt, die z.B. Natrium-lauroylisethionat und „in situ" erzeugte Sulfosuccinate enthalten. Aus US-A-4,007,125 sind Toilettenseifen auf Basis von Acylisethionaten bekannt, die zur Verringerung der Sumpfungsneigung ein Alkansulfonat und als Bindemittel freie gesättigte Fettsäure enthalten.From DE-A-31 29 280 a process for the production of detergent pieces was known which e.g. Sodium lauroyl isethionate and sulfosuccinates produced “in situ”. From US Pat. No. 4,007,125, toilet soaps based on acyl isethionates are known which contain an alkane sulfonate and free saturated fatty acid as a binder to reduce the tendency towards sumping.
Es wurde nun gefunden, daß sich das Arochäumvermögen und die Verarbeitungs¬ eigenschaften von Syndet-Seifen auf Basis von Acylisethionaten weiter verbessern und die Sumpfungsneigung verringern läßt, wenn man als weitere Tensidkomponente ein Alkyl- (oligo)-glycosid zusetzt.It has now been found that the aro-foaming power and the processing properties of Syndet soaps based on acyl isethionates can be further improved and the tendency to sump can be reduced if an alkyl (oligo) glycoside is added as a further surfactant component.

The molded products have a smooth surface that dries again after wetting with water without becoming 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, optionally pelletizing, extruding, cutting and piece pressing, such as those e.g. in JAOCS, Vol. 59, No. 10 (October 1982), 442-448, can also be used for the production of the Syndet soap compositions according to the invention.
Für die Herstellung von Toüetten-Seifenstücken auf Basis der erfindungsgemaßen Syndet- Masse hat sich folgende Arbeitsweise bewährt: Die schmelzbaren Komponenten, z.B. die Fettsäure, der Fettalkohol, das Alkyl-(oligo)- glucosid und ggf. schmelzbare oder flüssige Füll- und Hilfsstoffe werden bei einer Temperatur im Bereich von 60 - 90°C in einem heizbaren Kneter oder Mischer aufgeschmolzen und gemischt. Dann erfolgt die Zugabe des C_2-Cιg-Acyusethionat- Salzes, ggf. des Sulfosuccinats 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 following procedure has proven itself for the production of toilet soap bars based on the syndet composition according to the invention: The meltable components, e.g. the fatty acid, the fatty alcohol, the alkyl (oligo) glucoside and, if applicable, meltable or liquid fillers and auxiliaries are melted and mixed at a temperature in the range from 60 to 90 ° C. in a heatable kneader or mixer . Then the C_ 2 -Cιg-acyusethionate salt, optionally the sulfosuccinate and other components which cannot be melted at 60-90 ° C. and possibly the water, are added, and the batch is mixed or kneaded at a temperature of approximately 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 by pressing the mass several times through sieves and finally pressing it at a head temperature of 40 to 70 ° C. into a strand which is cut into uniform pieces. The pieces can finally be brought into their 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, in this way noodles or needles are obtained or, if the perforated plate is followed by knives, granules are formed.
Die nachfolgenden Beispiele sollen den Gegenstand der Erfindung näher erläutern, ohne ihn hierauf zu beschränken. The following examples are intended to explain the subject matter of the invention in more detail without restricting it thereto.

1.2 Herstellverfahren1.2 Manufacturing process
Die Herstellung der Syndet-Seifen erfolgte in einem heizbaren Kneter. Die Komponenten wurden darin auf 90°C erwärmt und intensiv gemischt. Nach Abkühlung auf 40°C wurden die Duftstoffe zugegeben und nach kurzem Mischen wurde die Masse in eine Strangpresse überführt.The Syndet soaps were produced in a heatable kneader. The components were heated to 90 ° C and mixed intensively. After cooling to 40 ° C., the fragrances were added and, after brief mixing, the mass was transferred to an extrusion press.
1.3 Die nach den Rezepturen der folgenden Tabelle erzeugten Syndet-Massen zeigten ein sehr gutes Schäum vermögen und praktisch kerne Neigung zur Sumpfbildung. 1.3 The syndet masses produced according to the recipes in the following table showed a very good foaming ability and practically no tendency towards sump formation.
