 | Chemical Properties | The essential oil is obtained from the B. alba and B. pendula Roth. |  | Physical properties | The essential oil of B. alba L. is a viscous, yellow liquid with a balsamic odor. It is obtained
from buds by steam distillation in 3.5 to 8% yields. The oil solidifies at low temperature because of its paraffin content. The essential
oil of B. alba L. var. pubescens Ehrl., obtained from buds in 3.5% yields by steam distillation, has a specific gravity of 0.9779. The
essential oil of B. alba I. obtained from bark is recovered in 0.4 to 0.5% yields. The essential oil obtained from leaves is recovered
in 0.4 to 0.5% yields. |  | Occurrence | Found in the tar of the bark and wood of Betula pendula Roth (fam. Betulaceae). |  | Preparation | By steam-distillation of the tar obtained by dry distillation of the bark and the wood of Betula pendula Roth (fam. Betulaceae). |  | Definition | Extractives and their physically modified derivatives.  Betula alba, Betula pendula and Betula pubescens, Betulaceae. |  | Safety Profile | A skin irritant. Moderatelyirritating to eyes and mucous membranes. A mild allergen.Combustible when exposed to heat or flame; can reactwith oxidizing materials. |
