Quality Control

Our Germacrene B is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as identity, assay, and impurity profiles. Our quality commitment aligns with ISO standards and relevant industry guidelines for fragrance and flavor ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (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 or argon) for long-term stability and to minimize degradation. Keep away from heat, sparks, and open flame.
