Descriptors

An intensely animalic, leather-narcotic material reminiscent of quinoline derivatives used in leather bases. Powerful fecal-indolic character with an underlying oily, floral-narcotic facet that recalls tuberose and orange-blossom indoles. Extremely diffusive and long-lasting even at trace levels.AI · claude-opus-4-7
