Hedione® HC (Firmenich)

An exceptionally fresh and radiant floral character defines this essential perfumery material. Its elegant profile is reminiscent of a transparent, luminous jasmine, brightened with natural-smelling citrus facets of lemon and grapefruit, and a subtle green nuance. As a high cis-isomer grade of methyl dihydrojasmonate, Hedione® HC from Firmenich offers a more powerful, purely floral, and less oily profile than its classic counterpart. This specific isomeric composition is key to its prized effect, delivering a diffusive and airy quality that feels both incredibly modern and timeless. First synthesized in the late 1950s, its introduction revolutionized perfumery by providing an entirely new texture and radiance previously unattainable.

The versatile nature of this compound allows for its use in nearly every olfactive family, where it imparts remarkable bloom, volume, and a seamless connection between fragrance notes. In compositions, it acts as an exalting agent, enhancing the diffusion of other materials and adding a sophisticated lift from the top notes through the heart. Recommended usage levels are exceptionally broad, ranging from just one or two percent to add a subtle sparkle, to over thirty percent where it forms the structural backbone of a fragrance. It combines beautifully with citrus accords to boost freshness, enriches floral bouquets with unparalleled naturalness, and provides a juicy, watery effect to fruity and tropical creations.
