Intensely animalic and fecal in high concentration, with a heavy indolic floral undertone reminiscent of jasmine and orange blossom absolutes. On extreme dilution it opens into a warm, narcotic, almost mothball-like floralcy that lends naturalness and depth to white florals. Signature is its powerful, clinging indolic-animalic character that reads as skin-like at trace levels.AI · claude-opus-4-7
