Die angegebenen Prozentsätze beziehen sich auf das Trockengewicht des Gemisches, das weniger als 10/0 Feuchtigkeit und flüchtige Stoffe enthielt. Die Teilchengrösse lag unter 0, 6 mm.
39, 93 Teile des obigen Gemisches, nun als Gemisch 1 bezeichnet, wurden mit 1, 8 Teilen Nonylphenoxypoläthylenoxyäthanolgemischtunddann während etwa 72 hin einer langsam rotierenden Trommel"gealtert". Dem so behandelten Gemisch wurden dann die folgenden Bestandteile (Gemisch II) hinzugefügt :

Davon wurden 39, 93 Teile innig mit 1, 80 Teilen Nonylphenoxypoly (äthylenoxy) äthanol ge- mischt. Danach wurden 5, 0 Gew.-Teile gepulvertes Pentanatriumtripolyphosphat (mit hohem Form 1Gehalt) hinzugegeben, und die bereits mit dem nichtionischen Detergens beschichteten Teilchen hiemit überzogen.

Aus der so erhaltenen Zubereitung konnten Waschtabletten mit vorzüglichen Eigenschaften hergestellt werden.
Die Zubereitung kann zur Herstellung von Waschtabletten nach bereits beschriebenen Methoden verwendetwerden. AuchMehrzweckwaschtabletten, die einen Kern aus Bleichmittel enthalten, können gemäss der brit. PatentschriftNr. 993, 583 hergestelltwerden, indem man beispielsweise zunächst das Bleichmittelpresstunddannmitder Detergentien-haltigen Zubereitung überzieht. Beispielsweise kann man die Aussenschicht in Form zweier getrennter Hälften, deren jede eine Aussparung enthält, vorformen, dann das Bleichmittel in die passende Form bringen und in die durch die beiden Aussenhälften gebildete Aussparung einsetzen. Die zweite Aussenhälfte kann dann auf die erste Aussenhälfte aufgepresst werden, wo- mitderInnenteil aus Bleichmittel vollkommen eingeschlossen ist.
Eine andere Möglichkeit der Herstellung besteht darin, dass man eine Formhälfte des Aussenteiles mit einer Aushöhlung mit pulverförmigem B leichmittel füllt, darauf dann weiteres Aussenmaterial (Detergentien-haltige Zubereitung) gibt und die gesamte Masse zu der gewünschten Form presst. Wird die erfindungsgemässe Zubereitung zur Herstellung vonMehrzweckkörpernmiteinemInnenteilausBleichmittelbenutzt, so sollten nicht mehr als 2% Feuchtigkeitund verdampfbare Substanzen enthalten sein. Die erfindungsgemässen Gemische können aber wie schon ausgeführt auch verwendet werden, um einschichtige Waschtabletten bzw. Presskörper ohne Bleichmittel-Kern herzustellen.

The percentages given are based on the dry weight of the mixture containing less than 10/0 moisture and volatiles. The particle size was below 0.6 mm.
39.993 parts of the above mixture, now referred to as Mixture 1, was mixed with 1.8 parts of nonylphenoxypolethyleneoxyethanol and then "aged" on a slowly rotating drum for about 72 hours. The following ingredients (mixture II) were then added to the mixture treated in this way:

From this preparation tablets u. Like. Are pressed, which in turn completely dissolved in 3 minutes and had excellent detergency.
Example 2: Mixture I (spray-dried component) was prepared as described in Example 1. 39.93 parts thereof were intimately mixed with 1.80 parts of nonylphenoxypoly (ethyleneoxy) ethanol. Then 5.0 parts by weight of powdered pentasodium tripolyphosphate (with a high form 1 content) were added, and the particles already coated with the nonionic detergent were coated with it. The resulting mixture was then mixed with mixture II of the following composition:

From the preparation obtained in this way, it was possible to produce washing tablets with excellent properties.
The preparation can be used for the production of washing tablets according to the methods already described. Multipurpose washing tablets containing a bleach core can also be used according to British patent specification no. 993, 583 by, for example, first pressing the bleach and then coating it with the detergent-containing preparation. For example, the outer layer can be preformed in the form of two separate halves, each of which contains a recess, then the bleaching agent can be brought into the appropriate shape and inserted into the recess formed by the two outer halves. The second outer half can then be pressed onto the first outer half, with the result that the inner part made of bleach is completely enclosed.
Another possibility of production consists in filling a mold half of the outer part with a cavity with powdery bleaching agent, then adding further outer material (detergent-containing preparation) and pressing the entire mass into the desired shape. If the preparation according to the invention is used for the production of multi-purpose bodies with an inner part made of bleach, it should not contain more than 2% moisture and vaporizable substances. However, as already stated, the mixtures according to the invention can also be used to produce single-layer washing tablets or compacts without a bleach core.
