Description

  

  Verfahren zur Herstellung eines schwefelreichen, wasserlöslichen Gemisches  von     höhermolekularen        Keratinabbauprodukten.       Die Hydrolyse von     Keratinen    mit Säuren  ist bekannt. Bekannt ist auch, dass man  durch Hydrolyse der     Keratine    mit Säuren  bis zum gallertartigen Zustand und Isolie  rung einer in Wasser unlöslichen Fraktion  zu schwefelreichen, wasserunlöslichen     Kera-          tinabbauprodukten    gelangen kann, während  die wasserlöslichen Abbauprodukte schwe  felärmer sind.  



  Es wurde nun gefunden, dass man ein  schwefelreiches, wasserlösliches Gemisch von       höhermolekularen        Keratinabbauprodukten    in  der Weise erhalten kann, dass man     Keratine     durch Hydrolyse mit Säuren bis auf geringe,  der Hydrolyse besonders lange widerstehende  Anteile löst, das saure Reaktionsgemisch un  mittelbar einer Dialyse unterwirft, filtriert.  und zur Trockne bringt. Das erhaltene Pro  dukt ist zur Verwendung als Kosmetikum  und als Zwischenprodukt für pharmazeu  tische Präparate bestimmt.  



  Versuche haben gezeigt, dass das durch  Eindampfen des nichtdiffundierten Hydroly-         sats    gewonnene Produkt wesentlich reicher  an Schwefel ist als die     Ausgangskeratine.     Verwendet man zum Beispiel Haar als Aus  gangsmaterial, so gewinnt man ein Produkt,  das einen Schwefelgehalt bis zu 7 % auf  weist. Schon nach drei- bis     fünftägiger    Di  alyse ist das Produkt so rein, dass es nur  noch 0,5 bis<B>1,5%</B> Asche enthält.  



  <I>Beispiel Z:</I>  200 g Haar werden mit 800 cm' 25 %     iger     Salzsäure auf dem Wasserbad zunächst vor  sichtig auf 40   C erhitzt, bis alles Haar von  der Säure bedeckt ist. Dann wird die Tem  peratur auf 70 bis 80   C erhöht und so lange  weiter     erhitzt,    bis nur noch ein kleiner Rest  ungelöst ist. Nach dem Abkühlen wird das       Hydrolysat    unmittelbar in einen Pergament  beutel gebracht und drei bis fünf Tage gegen  fliessendes Wasser dialysiert. Der Inhalt  des Pergamentschlauches, der jetzt nur noch  schwach sauer reagieren darf, wird filtriert  und zur Trockne eingedampft. Man erhält      ein gelbliches Pulver mit einem Gehalt von  zirka 7 % Schwefel.  



  <I>Beispiel 2:</I>  1.00 g Wolle werden mit 400 am' 25 %     iger     Salzsäure auf dem Wasserbad so lange auf  40   C erhitzt, bis die gesamte Wolle von  der Säure bedeckt ist. Hierauf wird bei 70  bis 80   C weiter     hydrolisiert,    bis die Wolle,  bis auf einen geringen unlöslich bleibenden  Anteil,     eben    in Lösung gegangen ist und das       Hydrolysat,    wie in Beispiel 1,     weiterbehan-          delt.  



  Process for the production of a sulfur-rich, water-soluble mixture of high molecular weight keratin breakdown products. The hydrolysis of keratins with acids is known. It is also known that hydrolysis of the keratins with acids to a gelatinous state and isolation of a water-insoluble fraction can lead to sulfur-rich, water-insoluble keratin breakdown products, while the water-soluble breakdown products are lower in sulfur.



  It has now been found that a sulfur-rich, water-soluble mixture of higher molecular weight keratin degradation products can be obtained in such a way that keratins are dissolved by hydrolysis with acids except for small portions that resist hydrolysis for a particularly long time, the acidic reaction mixture is immediately subjected to dialysis, and filtered . and brings to dryness. The product obtained is intended for use as a cosmetic and as an intermediate for pharmaceutical preparations.



  Tests have shown that the product obtained by evaporating the undiffused hydrolyzate is significantly richer in sulfur than the starting keratins. If, for example, hair is used as the starting material, a product is obtained that has a sulfur content of up to 7%. After just three to five days of analysis, the product is so pure that it only contains 0.5 to <B> 1.5% </B> ash.



  <I> Example Z: </I> 200 g of hair are first carefully heated to 40 C on a water bath with 800 cm 'of 25% hydrochloric acid until all of the hair is covered by the acid. Then the temperature is increased to 70 to 80 C and continued to be heated until only a small residue remains undissolved. After cooling, the hydrolyzate is immediately placed in a parchment bag and dialyzed against running water for three to five days. The contents of the parchment tube, which are now only allowed to react slightly acidic, are filtered and evaporated to dryness. A yellowish powder is obtained with a content of approximately 7% sulfur.



  <I> Example 2: </I> 1.00 g of wool is heated to 40 ° C. with 400 am '25% hydrochloric acid on a water bath until all of the wool is covered by the acid. This is followed by further hydrolysis at 70 to 80 C until the wool has just gone into solution, except for a small portion that remains insoluble, and the hydrolyzate is treated further as in Example 1.
