A heavy, tenacious chalcone-type aroma chemical with a soft balsamic-floral character and a faintly sweet, powdery warmth. Low volatility gives it a quiet, fixative presence rather than any bright top-note lift.AI · claude-opus-4-7

Appearance

Viscous yellowish oil, solidifying in the cold.

Solubility

Very slightly soluble in water, soluble in alcohol and oils.

Odor

Sweet-creamy, floral-balsamic tenacious odor. In dilution quite floral in the Sweet-Pea type, at higher concentrations it shows tendency of supplying spicy-warm notes.

Uses in perfumery

This ketone, rarely offered under its proper chemical name, is used in perfumery, mainly in specialties and floral-balsamic bases, in Fougere or Lavender additives, etc. It is quite powerful and has natural-lifting effect upon floral as well as non-floral fragrance types. Use concentration will normally be about 0.5 to 1.5°%, in a finished perfume oil.

Production

Produced by condensation of Benzaldehyde with Propiophenone.
