DESCRIPTION

Crude Dammar Gum occurs as irregular, white to yellow to brown tears, fragments, or powder, sometimes admixed with fragments of bark. Refined grades are white to yellow and are free of fragments of ligneous matter. Dammar Gum is the dried exudate from trees of the Agathis, Hopea, or Shorea genera. It consists of a complex mixture of acidic and neutral terpenoid compounds together with polysaccharide material. It is insoluble in water and in ethanol and is soluble in toluene and in limonene. A chloroform solution of Dammar Gum is dextrorotatory.
