In short
Jasmine lactone is an unsaturated six-membered lactone found in jasmine, tuberose and some fruits. It gives a creamy peach-apricot odour with a floral facet.
What Jasmine Lactone smells like
Jasmine lactone ((Z)-7-decen-5-olide, sometimes sold as jasminlactone) is a fatty-fruity lactone with a strong peach and apricot character. A distributor describes prominent peach and apricot skin notes with a celery-like undertone, supplying the heavy, waxy petal weight of natural tuberose and jasmine absolutes; a descriptor breakdown ranks fruity, coconut, fatty, creamy and peach first. It is reported in jasmine, tuberose, gardenia, honeysuckle, tea and peach. It is not the same compound as Firmenich's Jasmolactone.

What makes Jasmine Lactone distinctive
The lactone inside white flowers: peach-apricot skin with the waxy weight that makes a tuberose or jasmine reconstruction smell real.
How Jasmine Lactone is used
Used in jasmine, tuberose and gardenia accords and in peach and apricot notes, for natural petal weight and creaminess.
Typical role: modifier (used in small amounts to change the character of a blend).
How Jasmine Lactone differs from similar materials
- Tuberose Absolute
- Jasmine lactone is reported in tuberose and gives part of its creamy, peachy petal weight; the absolute adds methyl salicylate, methyl benzoate, indole and a heady sweetness.
- Veloutone
- Veloutone is lighter and more floral, with a lavender touch; jasmine lactone is heavier and waxier, with a celery undertone.
- gamma-Decalactone
- gamma-Decalactone is the fruit alone, ripe peach flesh; jasmine lactone carries peach skin into a waxy, floral petal note.
- Lactojasmone
- Lactojasmone, a gamma-lactone, is described by JECFA simply as jasmine.
- Frangipani Absolute
- Frangipani absolute is a whole creamy white flower with a peach in it; jasmine lactone is that peach-lactone note on its own.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
