Description and usage notes:
Strong, smoky material with a leathery quality.
Paler in colour and less bonfire-like than Cade Oil but still potent and dark brown.
Produced by destructive distillation of the twigs and leaves of Betula sp. and then rectified by steam distillation to remove most of the phenolic elements and meet the IFRA standard: crude Birch Tar should not be used in fragrances.
Arctander describes the product like this: “Rectified Birch Tar is a pale yellow to brownish yellow, clear and oily liquid, The odor description, ‘like Russian leather’, is conventional, but somewhat incorrect. Russian leather smells of birch tar because the leather is tanned with the tar products which also preserve this special type of leather. This circle of odor association is similar to the well-known: vanillin smells of chocolate!”
He goes on to talk more about the odour: “… distinctly phenolic, very penetrating and diffusive, obviously reminiscent of tar, charred wood and smoke (all of which have their odor from components of the birch tar oil!) However, the most characteristic feature in the odor pattern of birch tar oil is the sweet-oily undertone which appears distinctly on the smelling blotter when the first empyreumatic notes have faded away. These notes caught the immediate interest of perfumers long ago… ”
