What are the key aromatic compounds in orris absolute?
Irone is the signature compound of orris: the natural mixture of α-irone, β-irone and γ-irone isomers that carries the violet-powdery character. On average, orris butter contains about 15% total irone, which can be further enriched to roughly 60% by molecular distillation, and the α/γ-irone ratio is typically around 0.5.
Key Components
| Compound | Role |
|---|---|
| α-irone | Violet-floral, powdery core |
| β-irone | Green-woody nuances |
| γ-irone | Sweet, warm floral depth |
| Fatty acids/esters (myristic) | Creamy, waxy body |
| Iridals & starch-derived notes | Natural texture and fixative character |
- Irone content is quantified per ISO 18054:2004 using capillary-column GC with internal standard (column efficiency ≥50,000 theoretical plates)
- The total irone content is verified on every batch by GC-MS/GC-FID and reported on the COA
- Natural irone in the absolute is never synthesized or fortified; the composition reflects the genuine aged-rhizome profile
