About

Alpha Damascone is a potent synthetic rose ketone renowned for its diffusive fruity-floral radiance. It combines intense rose petal notes with crisp green apple, plum, and blackcurrant facets, accented by metallic, minty, and honeyed nuances. Highly impactful at trace levels, it bridges top and heart positions in fine fragrances.

Scent Profile

Alpha Damascone opens with a powerful rosy-floral core infused with crisp green apple and plum fruitiness, evolving into honeyed sweetness and tobacco-like dryness in the drydown. Subtle metallic and minty facets add complexity, alongside green undertones and a powdery texture. Its exceptional diffusion and tenacity provide radiant lift throughout fragrance development.

How the layers join

Origin

Alpha Damascone is a fully synthetic molecule, chemically (E)-1-(2,6,6-trimethylcyclohex-2-en-1-yl)but-2-en-1-one with CAS 24720-09-0, developed as part of the damascone family of rose ketones. Produced industrially by major fragrance houses like Givaudan and Firmenich, it mimics natural trace compounds found in roses and black tea. Strict IFRA regulations limit its use to 0.043% in finished fine fragrances due to potency.

Usage in Perfumery

Perfumers employ Alpha Damascone sparingly (0.1-1%) as a heart note with top-note lift in rose accords, fruity-florals, and tobacco compositions. It synergizes with jasmine, bergamot, sandalwood, and citrus for enhanced radiance and naturalness, as seen in Creed Aventus. Its fixative properties stabilize volatile florals while amplifying overall diffusion.
