  Description
  
  Gambir extract is a tanning agent extracted from the leaves of the Uncaria Gambir plant, which comes from Asia and only grows approximately 10° north or south of the equator line. The plant, which grows as a wild bush, can also be cultivated. The Gambir extract is won from the leaves, partly without the branches by extraction with water at a temperature of 85-90°C and evaporation. The powder is then made by the spray-dry method.
  
  Application
  
  By using Gambir extract only, a very soft leather can be obtained, particularly in the re-tanning of calf-leather. However, Gambir extract is also used for the re-tanning of chrome-tanned glove leather, with a remarkable fullness of the leather as well as softness and elasticity.
