Product Description

Castoreum Base is a proprietary synthetic perfume base, designed to replicate the rich, layered olfactory profile of natural castoreum absolute. It is developed as an ethical, stable and cost-effective alternative to animal-derived castoreum, which is limited in supply due to animal welfare and regulatory constraints.

This base delivers warm animalic leather character, with smoky phenolic undertones, resinous balsamic depth and subtle sweet vanilla-amber drydown. Compared to natural castoreum absolute, this synthetic base features consistent batch-to-batch aroma, fewer heavy off-notes and predictable solubility in fragrance concentrates. It is a widely used foundational ingredient for chypre, oriental, leather, tobacco and niche luxury fragrance compositions. It possesses excellent fixative power, anchoring volatile top and middle notes and extending the longevity of finished perfume blends.
