Additionally, regulations around animal cruelty have led to stricter controls over the harvesting of castoreum in many regions.

The synthetic version replicates the warm, leathery, and slightly sweet animalic notes of natural castoreum but without the need for animal by-products.

Castoreum Lends a "Dirty" Note to Perfumes

They live in colonies of 10 to 80 individuals and defecate in the same spot.

When it was used, castoreum provided a rich, creamy undertone that enhanced the sweetness of desserts and flavored beverages.
