Dihydroisojasmone
CAS 95-41-0
What Is Dihydroisojasmone?
Dihydroisojasmone is a synthetic fragrance ingredient used to add floral, fruity nuances to perfumes and scented products. You’ll encounter it in fine fragrances, body care items, and household cleaners. This versatile molecule mimics natural floral scents while offering superior stability, making it a perfumer’s secret weapon for creating long-lasting, sophisticated accords.
Safety Profile
GENERALLY SAFEWhat Does Dihydroisojasmone Smell Like?
Dihydroisojasmone opens with a dewy floralcy reminiscent of jasmine petals dipped in honey, quickly revealing a plush fruity core like overripe apricots in sunlight. As it dries, the scent develops woody-amber undertones that add depth without heaviness, leaving a skin-hugging sillage that’s intimate yet persistent. The overall effect is like a silk scarf fluttering in an orchard breeze – weightless but unforgettable.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used here to amplify the floral bouquet with its honeyed fruitiness, creating the signature ‘golden water’ effect that makes this fragrance shimmer.
Provides the soft jasmine-tea nuance that balances the citrus top notes, giving this fresh floral its distinctive ‘petal-soft’ character.

Chemistry, Properties & Perfumer Guide
The Chemistry
Dihydroisojasmone belongs to the cyclic ketone class, specifically a hydrogenated derivative of isojasmone. While jasmone occurs naturally in jasmine absolute, this synthetic version offers greater stability and purity. Industrially produced via hydrogenation of isojasmone or through condensation reactions of appropriate precursors, its structure allows for excellent tenacity in fragrance formulations. The molecule’s conformational flexibility contributes to its ability to bridge floral and fruity olfactive spaces.
