  Emulsion für   Gerbeieizwecke.   
 EMI1.1 
 Emulsionen zu bilden. 



   Diese Emulsionen sind mit Vorteil in der Gerberei anwendbar. 



   Als Metallhydroxyd hat sich frisch gefälltes, feuchtes Aluminiumhydroxyd als besonders günstig erwiesen. Durch dessen Verwendung kann eine wesentlich feinere Emulsion von grösserer Stabilität hergestellt werden als bei Anwendung von Ton in fein verteiltem trockenen Zustande. 



   Es hat sich weiter noch als vorteilhaft gezeigt, Harnstoff mitzuverwenden, der bei Anwendung der Emulsion in der   Gerberez, dise   Färbung günstig beeinflusst. 



   Beispielsweise wird folgendermassen gearbeitet :
10 kg Klauenöl werden mit 1 kg frisch gefälltem, gut ausgewaschene, feuchtem Aluminiumhydroxyd innig vermischt. Es entsteht eine Emulsion, die im Bedarfsfall, z. B. für   Gerbereizweeke,   noch einen entsprechenden Wasserzusatz erhält und trotzdem in kolloidaler Lösung bleibt. 



   PATENT-ANSPRÜCHE :
1. Emulsion für Gerbereizwecke, bestehend aus Fett oder Öl und fein verteilten anorganischen Stoffen, dadurch gekennzeichnet, dass als Emulgator ein frisch gefälltes Metallhydroxyd zur Anwendung gelangt. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Emulsion for tanning purposes.
 EMI1.1
 To form emulsions.



   These emulsions can be used with advantage in tannery.



   Freshly precipitated, moist aluminum hydroxide has proven to be particularly favorable as a metal hydroxide. By using it, a much finer emulsion of greater stability can be produced than when using clay in a finely divided dry state.



   It has also been shown to be advantageous to use urea, which has a favorable effect on the coloration when the emulsion is used in the tannery.



   For example, it works as follows:
10 kg of hoof oil are intimately mixed with 1 kg of freshly precipitated, well washed, moist aluminum hydroxide. The result is an emulsion which, if necessary, e.g. B. for tannery wheat, still receives a corresponding addition of water and still remains in colloidal solution.



   PATENT CLAIMS:
1. Emulsion for tanning purposes, consisting of fat or oil and finely divided inorganic substances, characterized in that a freshly precipitated metal hydroxide is used as the emulsifier.
