Botanical name :

Betula alba

Botanical profile :

Tree belonging to the Betulaceae family and the Betula genus.

Geographic origin :

Native to the Arctic regions, birch is mainly produced in Scandinavia

Extraction process :

The birch is a tree that generally grows on poor, often siliceous soils up to 2000 meters altitude, as well as in arctic regions, such as in Lapland. These trees can live for more than a hundred years. Its essential oil is obtained by dry distillation, which mean by pyrolysis of the wood. The wood is heated from 1112 to 1472 °F in an oven to evaporate the water and at the outlet, collect a viscous and dark mixture with a smoky smell : birch tar.
This strong heat forms benzopyrenes in the birch tar. These compounds are carcinogenic and must be removed. The tar is heated under vacuum to collect a distillate that contains 10 ppm rather than 1000 ppm of benzopyrenes. This is how the rectified essential oil of birch is obtained, almost colourless.

Chemotypes :

There are about 150 species of birch around the world. However, very few are used in perfumery. We can mention:
Betula alleghaniensis or Yellow Birch.
Betula nigra L. or Black Birch.
Betula Pubescens Ehrh. or Betula Alba. White birch. (Mostly used)

Aromatherapy :

Informations provided below are taken from reference works in aromatherapy. They are given for information purposes only and can not constitute medical information, nor engage the responsibility of ScenTree.

The richness of Birch essential oil in Methyl Salicylate gives it rheumatic, antispasmodic and analgesic properties.

Cause of restriction :

CARGINOGENICITY, GENOTOXICITY

Amendment :

Comments :

Crude birch wood (bark) pyrolysates (oils) derived by pyrolysis (destructive distillation) of the wood or bark of Betula Pubescens, Betula Pendula, Betula Lenta or Betula Alba should not be used as a fragrance ingredient. Only rectified (purified) birch tar oils being in compliance with the below limitations for polynuclear aromatic hydrocarbons should be used. Limit content of polynuclear aromatic hydrocarbons (PAH) resulting from the use of rectified oils according to Good Manufacturing Practice. Benzopyrene and 1,2-Benzanthracene are to be used as markers for PAH. If used alone or in combination with rectified Cade oil, rectified Styrax oil or rectified Opoponax oil, the total concentration of both of the markers should not exceed 1 ppb in the final product.
