Javanol®

Uses in perfumery :

Javanol® is used for the same reasons as Bacdanol®, and for its aromatic facet, similar to thyme. Often used in small quantities as it is a very powerful and effective ingredient.

Year of discovery :

1996

Natural availability :

Javanol® is not available in its natural state.

Isomerism :

Javanol® has several asymmetric carbons that give rise to several possible isomers. Nevertheless, it is a mixture of isomers that is used in perfumery. In addition, Javanol® is a constitutional isomer of Polysantol®. These two compounds have a similar structure, and are used for similar reasons in perfumes. Javanol® still has a less milky note than Polysantol®, but is more powerful.

Synthesis precursor :

Javanol® is not involved in the synthesis of another compound of olfactory interest.

Synthesis route :

Javanol® is synthesized by a Simmons-Smith double reaction, consisting in cyclopropanation from 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol. This reaction involves a catalysis with Zinc and Copper, as well as diodomethane, to convert a double bond into a cyclopropane group.

Stability :

Unstable exclusively in acid cleaners and in bleach.

Other comments :

The detection limit of Javanol® is extremely low. This makes it one of the most used santal compounds, because it brings a milky and woody effect, even at a very small dosage.

Allergens :

This ingredient does not contain any allergen.
