About Indole

Indole is an aromatic molecule found in jasmine and other flowers, and it is also available as a synthetic perfumery material. Its chemical structure combines a benzene ring with a nitrogen-containing five-membered ring. As a perfume note, the name refers to the aromatic molecule rather than to a particular flower or a complete botanical extract.

Scent Profile

Its impression changes markedly with concentration. In small amounts it contributes the rich, heady depth associated with white flowers; at greater concentration a forceful animalic character becomes apparent. That range gives floral compositions an intimate, living quality and a darker edge beyond simple floral sweetness. The surrounding materials also influence how the effect is perceived.

Use in Perfumery

Perfumers use indole when building jasmine and other white-flower accords, where it adds density at the centre of the floral impression. It can supply depth beneath brighter floral ingredients without necessarily making the finished composition smell overtly animalic. The amount and the other materials in the formula determine that balance.

Did You Know?

Natural flower extracts contain many aromatic constituents alongside indole. A synthetic sample of the molecule and a complete jasmine extract therefore do not smell identical, even though they share this constituent. Concentration and context help explain the molecule’s unusually wide sensory range.
