A soft, creamy sandalwood-like note with a smooth, slightly milky-balsamic character. Less intense and more diffuse than natural santalol, with a gentle sweet-woody warmth that lends roundness and a subtle fruity-buttery nuance to woody accords.AI · claude-opus-4-7

Appearance

Almost colorless, slightly viscous liquid.

Solubility

Insoluble in water, soluble in alcohol and oils.

Odor

Fruity-balsamic, sweet and woody, very tenacious odor, not as mellow or 'round' as the odor of the n-Butyrate, but slightly fresher.

Uses in perfumery

This ester, by most perfumers considered less interesting than the n-Butyrate, but by many chemists considered less prone to decompose and produce free acid, is occasionally used in perfume compositions of the Chypre, Fougére, Moss-rose, 'tabac', Bruyére and similar fragrance types. It supplies excellent fixation in a Fougére, and it may contribute to the most desirable notes in a powder perfume. It is also a common ingredient in the rather unfashionable type of fragrance, called 'Oriental Rose'.

Production

Produced by azeotropic esterification of Santalol with iso-Butyric acid.
