In short
Georgywood is a Firmenich woody material related to the Iso E Super family. It gives a more powerful, diffusive woody note.
What Georgywood smells like
Georgywood is a captive woody-amber molecule described, in the glossaries found, as rich, warm and slightly sweet, like polished woods and soft amber, opening slightly spicy and aromatic before settling into deeper woody qualities. No manufacturer description was found, and sources disagree about which house makes it; one entry also gives a different CAS number and identity, so its details should be treated with caution.
- Leading note
- Warm polished wood
- Supporting facets
- Amber
- Faint facets
- Spicy, aromatic
- Character
- Warm, rich, smooth
What makes Georgywood distinctive
A warmer, sweeter polished wood among the woody-ambers.
Where the descriptions disagree: Sources disagree on the manufacturer, and one entry gives a different CAS number.
How Georgywood is used
Used as a woody-amber body in woody, oriental and masculine compositions.
Typical role: modifier (used in small amounts to change the character of a blend).
How Georgywood differs from similar materials
- Iso E Super
- Iso E Super is more transparent and velvety; Georgywood is described as richer, warmer and slightly sweet.
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.
Formulation considerations
More powerful than Iso E Super; adjust levels when substituting.
