Description and usage notes:

Unusual and rarely offered ingredient that gives the core odour character to the scent of Buddliea flowers.  Deceptively strong, and here offered at 10% dilution in ethanol to make it more affordable.

This material was featured at the World Perfumery Congress in 2016.

Arcadi Boix Camps. describes this as a tobacco odourant essential for both tea and tobacco bases.

See the entry for the pure product for applications where ethanol would be inappropriate.
