What is betulin?

Betulin is an extract from bark of the white birch tree, which has been known since the 18th century and is chemically defined. Betulin was discovered by German-Russian chemist Johann Tobias Lowitz. He was the first scientist to study and characterise betulin, and in doing was one of the first to isolate an active plant ingredient.     
Betulin is a substance of pure plant origin that gives the birch bark its typical white colour. Betulin protects birch trees from environmental effects, such as extreme temperatures, pest infestations and solar radiation. In numerous scientific studies, the natural active ingredient betulin has been found to have anti-inflammatory, anti-bacterial and wound-healing properties.

The properties of betulin

These properties of betulin and the skin applications passed down through history make its use in skin care only logical. However, betulin’s insolubility in water and low solubility in fat made it impossible to use before now. Birken AG devised an invention which led them to create the first patented process for extracting high-quality betulin from birch bark. The betulin binds itself to beneficial oil and water to make a stable emulsion, the patented betulin emulsion. This unique water-in-oil emulsion does not use any emulsifiers, preservatives, colourants, lanolin or paraffin at all. This is an innovation in skin care.    

Betulin is completely harmless for people allergic to birch pollen, as the allergens responsible for this allergy are found in the flowers of the birch tree and not in its bark.
