castoreum resinoid

Castoreum resinoid is a complex natural extract obtained from the castor sacs of beavers, presenting as a viscous, dark-colored substance. It provides a distinctive animalic, leathery, and phenolic aroma with resinous undertones. This material, also known by synonyms like castoreum oil and oils castoreum, belongs to animal-derived flavor and fragrance agents. Its chemical complexity contributes to its valued sensory profile, widely utilized in fine perfumery and flavoring formulations. Detailed chemical information on castoreum resinoid is available through resources such as PubChem. The production of castoreum resinoid involves collecting secretions from beaver scent glands, followed by solvent extraction to yield the resinoid used commercially.

Castoreum resinoid originates biologically from beavers, specifically sourced from their castor sacs. Its use as a flavor and fragrance agent harnesses its rich animalic and leathery scent qualities, making it suitable for complex perfume accords and certain flavor profiles in food and beverages. The IFRA (International Fragrance Association) Code of Practice (Global) provides regulatory guidelines governing its safe use in fragrancing. Due to the aromatic strength and unique notes of castoreum resinoid, it is typically used in small concentrations, combined carefully with other ingredients to develop warm, naturalistic scent impressions and nuanced flavor effects.

Castoreum resinoid displays moderate solubility in alcohol and limited water solubility, which influences its formulation compatibility primarily with alcoholic and oil-based bases. The substance maintains stability for approximately 24 months or longer when stored in cool, dry conditions protected from heat and light, ensuring the preservation of its sensory and chemical integrity. Its viscous texture and resinous nature necessitate handling in well-sealed containers to prevent volatilization and deterioration. These properties support its use in complex fragranced products where durability and scent evolution are critical.
