About this composition

This immortelle profile is tuned toward the common Corsican-style commercial material described in public sources. It uses the 2001 Corsica study for wide neryl-acetate bounds, a recent French organic GC-MS report for lot-typical values, and AromaWeb's public Tisserand-derived ranges for the signature immortelle markers. Additional minor constituents were cross-referenced from the same Praan Naturals / EVS organic French-origin GC-MS report used in the companion generic Helichrysum record to extend compositional closure.

What we're still learning · 3 data gaps

Good decisions start with knowing what is — and isn't — in the evidence.

No public source reviewed in this pass provided a native 0-100 odor-intensity score; 65 is an archive normalization of AromaWeb's qualitative 'Medium - Strong' aroma-strength band.
No public source reviewed in this pass provided verified volatility-rate or tenacity-hour values.
Public open CAS confirmation for gamma-curcumene, ar-curcumene, and italidione I was not verified in this pass, so those CAS fields remain null rather than guessed.
