Geranyl tiglate (CAS 7785-33-3) — Floral Middle Note Fragrance Ingredient
Geranyl tiglate
CAS 7785-33-3
What Is Geranyl tiglate?
Geranyl tiglate is a synthetic fragrance ingredient used in perfumes and personal care products. It’s valued for its fresh, floral, and slightly fruity aroma. This ester compound helps create natural-smelling floral bouquets and adds complexity to fragrance compositions.
Safety Profile
GENERALLY SAFEWhat Does Geranyl tiglate Smell Like?
Geranyl tiglate opens with a bright, fresh floral character reminiscent of rose petals and lily of the valley. The heart reveals a juicy, slightly tropical fruitiness akin to ripe passionfruit, while the dry-down carries a soft, powdery muskiness. The tiglate moiety adds a subtle animalic depth that prevents the floral aspects from becoming too sweet or cloying. It behaves like a natural floral absolute but with superior stability in formulations.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used as a modern floralizer to enhance the abstract floral bouquet, providing lift to the aldehydic top notes while blending seamlessly with the ylang-ylang and rose heart.
Contributes to the luminous floralcy, bridging between the fresh pear top notes and the rich damask rose heart with its dual fruity-floral character.

Chemistry, Properties & Perfumer Guide
The Chemistry
Geranyl tiglate is an ester formed from geraniol and tiglic acid. As a synthetic material, it’s typically produced via acid-catalyzed esterification. The molecule features both a terpene alcohol moiety (geraniol) and an unsaturated carboxylic acid (tiglic acid), giving it unique stability and odor properties. The trans configuration of the tiglate double bond contributes to its clean floral character without excessive sweetness.
