floraljasmin

An intensely indolic aromachemical with a heavy narcotic-floral character reminiscent of jasmine and orange blossom absolutes, laced with a distinctly fecal-animalic underpinning. Softer and slightly more floral than plain indole, with a warm mothball-like nuance that opens into a rich white-floral facet on dilution.AI · claude-opus-4-7
