Jasmolactone extra

Uses in perfumery :

Jasmolactone is used in luxury perfumery for reconstitutions of white flowers, for ambery notes and to give facets to a tea note.

Year of discovery :

1961

Natural availability :

Jasmolactone is only present in trace amounts in Osmanthus Absolute, not allowing to obtain it in its natural state.

Isomerism :

Another molecule is also called δ-Jasmolactone, but is synthesized from 4-hydroxydec-7-enoic acid, which places the double bond of the final product on another carbon aside. The smell of this isomer is similar to the Jasmolactone described here. Gamma-Jasmolactone has a more fatty smell, close to peanut. Methyl Laitone® is a constitutional isomer of Jasmolactone, but has a coconut-like smell and a lactonic body.

Synthesis precursor :

Jasmolactone is not a precursor to the synthesis of another compound of olfactory interest.

Synthesis route :

Like the other lactones, Jasmolactone, is synthesized by an intramolecular esterification reaction that involves 4-hydroxydec-8-enoic acid, in the presence of an acid catalyst. Then, the cyclization of this molecule gives rise to a δ-lactone.

Stability :

Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.

Other comments :

Jasmolactone has a jasmine undernote that makes the difference with other lactones as Delta-Decalactone.

Allergens :

This ingredient does not contain any allergen.
