Description

Birch Oil is a natural essential oil derived from the bark of the birch tree, primarily *Betula lenta* (sweet birch) or *Betula pendula* (European white birch). This product is valued for its distinct, sharp, and wintergreen-like aroma, primarily due to its high methyl salicylate content. It serves as a key aromatic and functional ingredient for manufacturers in the fragrance, flavor, and personal care industries. Global buyers rely on our supply for consistent quality and purity to meet stringent formulation requirements.

Quality Control

Our Birch Oil is produced and tested to ensure it meets the high standards required by our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flames.
