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. |
