As a supplier concerned about the quality of our products, our main focus is the production of tannic acid or gallotannins, a specific subgroup of the large tannin family. Only 4 botanical raw materials contain sufficient amounts of tannic acid to be of commercial value: Chinese gallnuts, Aleppo gallnuts, sumac leaves and tara pods.

Depending upon the application, choosing the right product with an appropriate molecular weight distribution has a major influence on final performance.
