Citronellyl tiglate (CAS 24717-85-9) — Floral Heart Note Fragrance Ingredient
Citronellyl tiglate
CAS 24717-85-9
What Is Citronellyl tiglate?
Citronellyl tiglate is a synthetic fragrance ingredient used in perfumes and personal care products to add fruity, floral, and slightly spicy notes. It’s often found in body lotions, shampoos, and fine fragrances. This molecule matters because it helps create long-lasting, complex scent profiles that evolve beautifully on skin, bridging between top and heart notes with its versatile character.
Safety Profile
GENERALLY SAFEWhat Does Citronellyl tiglate Smell Like?
Citronellyl tiglate opens with a bright, fruity burst reminiscent of ripe peaches and bergamot, quickly revealing a floral heart that suggests roses washed in morning dew. As it dries down, a subtle spicy warmth emerges, like crushed geranium leaves with a whisper of black pepper. The dry-down maintains a soft, musky-sweet character that lingers close to skin, creating an intimate sillage. Its evolution is remarkably smooth, transitioning seamlessly from juicy top notes to a sophisticated floral-woody base.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used here to amplify the grapefruit-quince top while softening the transition into the jasmine heart, adding diffusion and longevity without overpowering the delicate floralcy.
Provides a juicy, sun-warmed stone fruit effect that complements the tuberose, preventing the white flowers from becoming too indolic or heavy.

Chemistry, Properties & Perfumer Guide
The Chemistry
Citronellyl tiglate is an ester formed from citronellol and tiglic acid. As a synthetic material, it’s typically produced via acid-catalyzed esterification under controlled conditions. The molecule features both a terpene alcohol moiety and an unsaturated carboxylic acid component, giving it unique polarity and reactivity characteristics. Its α,β-unsaturated ester structure contributes to both its stability and olfactory properties.

Classic Accords
Tip: Use with ionones to create peachy-rose effects that last through dry-down.
Alternatives & Comparisons
For brighter, more citrusy effects with less floralcy and shorter duration.
When a deeper, more honeyed rose character is desired with similar longevity.
Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. Consult current IFRA Standards Library before formulating.
IFRA Status
Not restricted under current IFRA standards (Amendment 49).
RIFM Assessment
Considered safe for use in current applications based on RIFM’s 2015 fragrance material safety assessment.
Sustainability
As a synthetic material, citronellyl tiglate avoids agricultural land use but requires petrochemical feedstocks. Modern production methods aim to minimize waste and energy consumption. Its efficiency in formulations (requiring lower doses than many naturals) contributes to reduced environmental impact per unit of fragrance.
