cis-Jasmone

What cis-Jasmone smells like

cis-Jasmone is a jasmine material whose character is as much herbal as floral. Arctander describes the pure material as recalling celery seed, with some finding it bread-like, fruity or waxy, and most appealing below one percent. Bedoukian describes a very diffusive jasmine note with celery seed and a hint of black tea; Givaudan gives floral, green, jasmine and warm, Takasago floral, jasmine, spicy and fruity.

What makes cis-Jasmone distinctive

The celery seed. It is the green, herbal, tea-like part of jasmine — the note that makes real jasmine smell alive rather than sweet.

Concentration and dilution

Arctander notes it is most appealing at low concentrations, below one percent.

How cis-Jasmone is used

Used in traces in jasmine and white-floral reconstructions and in green florals for naturalness.

Typical role: modifier (used in small amounts to change the character of a blend).

How cis-Jasmone differs from similar materials

Dihydrojasmone

Dihydrojasmone is fruitier, with woody and herbal nuances; cis-jasmone is greener, with celery seed and tea.

Methyl Jasmonate

Methyl jasmonate is the sweeter, more floral jasmine; cis-jasmone is greener and herbal.

Jasmine Absolute (Grandiflorum)

The absolute's green, tea-like freshness comes partly from cis-jasmone; the absolute adds richness, honey and indole.

Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
