Descriptors

A dense, animalic-floral aromachemical with the characteristic naphthalene-like, mothball facet of the indole family, softened and made warmer by the ethyl substitution. Less sharply fecal than plain indole, with a more diffusive white-floral undertone that recalls jasmine, orange blossom and civet-like nuances. In dilution it lends narcotic, skin-like depth to floral accords.AI · claude-opus-4-7
