In short
Galbanum CO2 extract is a supercritical extract of the gum resin of Ferula gummosa: intensely green like the oil, with a fuller, more resinous body.
What Galbanum CO2 Extract smells like
Original Swiss Aromatics sells a CO2 extract of the gum resin of Ferula galbaniflua (syn. F. gummosa) and describes a green scent with musky undertones. dsm-firmenich sells a galbanum SFE extract and says the supercritical process preserves the natural profile. A supplier glossary describes CO2 extraction as giving a fuller, more resinous profile than distillation.

Galbanum with the resin left in: greener than the resinoid, fuller than the oil.
Where the descriptions disagree: CAS numbers given for galbanum extracts differ between listings.
How Galbanum CO2 Extract is used
Used for green impact and naturalness in chypre, green floral and fougère compositions.
Typical role: modifier (used in small amounts to change the character of a blend); lift (adds diffusion and radiance, especially at the top).
Formulation considerations
Very powerful; dose from dilution. Listings give different CAS numbers for galbanum oil and gum extracts, so check the supplier's documents.
