Hedione HC (Firmenich)

Hedione HC (Firmenich Original) — Chanel Style Magnolia-Jasmine Bloom

Hedione HC (High Cis) is a special version of classic Hedione produced by Firmenich; the proportion of the cis isomer, which gives Hedione its characteristic power, bloom, and radiance, is significantly increased (68.5% cis / 29.9% trans in this product). Hammeyd stocks Firmenich original Hedione HC in Turkey.

Chanel's secret weapon: Hedione HC is a molecule often favored by Chanel perfumers in their modern compositions. It is especially used in combination with Muscenone Delta and Exaltone crystals. This combination forms the structural core behind the airy, clean, and fresh sensation in modern Chanel perfumes.

Difference from classic Hedione: Although Hedione HC contains a higher cis isomer, due to the overall composition of the product, it is not more radiant than classic Hedione. It offers a different character: a more pronounced magnolia note, a richer and more distinct jasmine sweetness, and an enhanced blooming effect. While classic Hedione is "quiet and universal," Hedione HC has a clearer floral expression.

Alternative names: Kharismal Super, Hedione HC.

Frequently Asked Questions

Where to buy Hedione HC in Turkey?
Hammeyd is an e-commerce store that regularly stocks Firmenich original Hedione HC (High Cis) in Turkey. Shipping is available domestically and to selected international countries.

Should I buy Hedione or Hedione HC?
They are different isomer-balanced versions of the same molecule (Methyl Dihydrojasmonate) and complement each other:
• For a classic perfume structure, a universal boost, a transparent citrus-floral in the style of Eau Sauvage → Classic Hedione
• For modern magnolia-jasmine floralcy, a bloom effect, modern compositions in the style of Chanel → Hedione HC
Professional perfumers typically keep both in their palette.

Is Hedione HC stronger than classic Hedione?
No, it is not "stronger" in a simple sense. Despite containing more cis isomer, due to the overall composition of the product, it is not even more radiant than classic Hedione. It offers a different character: a more pronounced magnolia-jasmine expression, a more intense blooming effect. Both have their unique value.

Are Hedione HC and Paradisone the same thing?
No. Paradisone is a Firmenich captive variant and is not sold commercially. Hedione HC is somewhere between classic Hedione and Paradisone. The closest market equivalent to Paradisone is a molecule called Paradise Molecule.

How is Hedione HC used in Chanel perfumes?
Chanel perfumers typically pair Hedione HC with Muscenone Delta (soft musk) and Exaltone crystals (clean musk). This combination creates the characteristic clean, airy, floral structure of modern Chanel compositions.
