Jasmonal H
Premium Synthetic Ingredient for Perfumery
Jasmonal H [CAS 54464-57-2] is a synthetic aromatic ketone developed by IFF, classified within the woody–ambery olfactory family. Enriched in the gamma isomer, it provides a smoother, fuller, and more floralized version of traditional Iso E Super. Its velvet-like profile offers refined strength and modernity to both fine fragrance and personal care formulations. Jasmonal H excels as a floralizer and volume enhancer, especially in luxurious soap and fine fragrance bases.

What is Jasmonal H?
Jasmonal H is an isomer-enriched variant of Iso E Super®, optimized for higher content of the gamma isomer responsible for its unique olfactory richness. Structurally classified as a substituted tetralin ketone, it belongs to the family of bicyclic woody-amber molecules, which includes other high-performance ingredients like Timbersilk®, Ambralux®, and Isocyclemone E.
Originally derived from synthetic ionone chemistry, the gamma isomer of Iso E Super was identified as the key contributor to its distinctive velvety diffusion. Jasmonal H refines this effect through isomeric selection, delivering greater impact and floral-amber richness.
Olfactory Profile & Perfumery Applications
Jasmonal H is valued for its rounded, dry-woody signature with floral-ambergris overtones. Less metallic and sharper than raw Iso E Super, it adds:
Smoothness and volume to floral compositions (e.g., jasmine, rose, ylang-ylang)
Structure and radiance to woody bases (e.g., vetiver, cedarwood, sandalwood)
Subtle ambergris effects in musky, oriental, and modern fougère accords
Ideal for:
Fine fragrance: floral, woody, woody-floral, modern ambers
Soaps and personal care: highly compatible, smooth diffusion
Functional perfumery: deodorants, haircare, and softeners needing olfactory depth
Use level: typically between 0.1% to 8%, depending on concentration and desired radiance.
Industrial & Technical Uses
Jasmonal H is chemically stable, non-discoloring, and compatible across various base types:
Alcoholic perfumery
Soap and surfactant systems
Detergents and softeners
Candles and air fresheners
It is especially prized in bar soap production due to its excellent olfactory clarity and lack of discoloration over time.
Regulatory & Safety Overview
IFRA Guidelines: Jasmonal H is regulated under IFRA for category-specific limits, though less restricted than Iso E Super
EU Allergens: Does not fall under the 26 declarable fragrance allergens per EU 1223/2009
ECHA Classification: Not classified as hazardous
REACH: Registered for fragrance applications
Toxicological Notes:
Not sensitizing in standard dermal patch tests
Low aquatic toxicity
Biodegradable under OECD conditions
Storage: Store in a tightly sealed container, protected from heat and light
✅ Jasmonal H meets modern safety standards for fragrance use in both fine and functional formulations.
