Fragrance allergens › Evernia Prunastri Extract
Evernia Prunastri Extract (CAS 90028-68-5) is one of the fragrance allergens the European Union requires to be named on a label once it passes a threshold. It is rarely something you added on purpose: 2 materials in this catalog carry it as a constituent, which is how a formula ends up over the line without a single line item admitting to it.

IFRA-compliant oakmoss: the same deep forest-floor, ink and bark character with atranol and chloroatranol removed. The moss modern chypres are actually built on.
It is a material in its own right, not only a line on a label: its catalog page carries the full profile.
What the ceiling is really controlling is atranol and chloroatranol: the extract has to carry less than 100 ppm of them. The Category 4 figure is shared with treemoss extracts rather than counted separately.
3 of the 5 carriers in this catalog are naturals and 2 are synthetic. The heaviest carrier that is not the molecule itself is Mousse de Saxe, at about 10%.

Estimates from typical published compositions, not a certificate of analysis for your bottle. A supplier's own figures always win.
PerfuMate totals these across a whole formula while you compose, counting the same molecule arriving from several materials at once, and writes the declaration for the back of the bottle. Start a formula, free. No account needed.
