  " EMULSION " 
Cette invention concerne une émulsion plus spé- cialement utilisable en tannerie. 



   On a trouvé que des hydroxydes métalliques   fraî-   chement précipités, communiquent aux huiles et graisses insola -bles, la faculté de former des émulsioes. 



   Ces émulsions sont utilisables avec avantage dans la tannerie. 



   On a trouvé que l'hydroxyde d'aluminium   fraî-   chement précipité et encore humide, est   particulièrement,   ap- proprié comme hydroxyde métallique. 



   On a trouvé également qu'il était avantageux d'utiliser en même temps de l'urée, qui, lors de l'emploi de l'émulsion en tannerie, exerce une influence favorable sur la coloration. 



   On travaille par exemple comme suit:      

 <Desc/Clms Page number 2> 

 
10 Kgs d'huile de pieds de boeuf sont intimement mélangés avec un kilo d'hydroxyde d'aluminium humide, fraîchement précipité. Il se produit une émulsion qui, suivant l'usage, par exemple pour des buts de tannage, reçoit encore une ad- dition d'eau convenable et reste malgré cela en solution colloïdale. 



   REVENDICATIONS. 



  I- Enulsion destinée en particulier au tannage, constituée d'une huile ou graisse et d'un hydroxyde métallique fraîche- ment précipité.

  "EMULSION"
This invention relates to an emulsion more especially useful in tannery.



   Freshly precipitated metal hydroxides have been found to impart to insoluble oils and fats the ability to form emulsifiers.



   These emulsions can be used with advantage in the tannery.



   Freshly precipitated and still wet aluminum hydroxide has been found to be particularly suitable as a metal hydroxide.



   It has also been found to be advantageous to use urea at the same time, which, when using the emulsion in tanning, has a favorable influence on the coloring.



   We work for example as follows:

 <Desc / Clms Page number 2>

 
10 kg of beef foot oil are intimately mixed with one kg of wet, freshly precipitated aluminum hydroxide. An emulsion is produced which, depending on use, for example for tanning purposes, still receives a suitable addition of water and nevertheless remains in colloidal solution.



   CLAIMS.



  I- Enulsion intended in particular for tanning, consisting of an oil or fat and a freshly precipitated metal hydroxide.
