How much Treemoss extracts can you put in a perfume?
IFRA standard: Treemoss extracts · Category 4, 51st Amendment
0.1%
of the finished perfume, at most
Under the IFRA Standards (51st Amendment, Category 4: fine fragrance on skin), Treemoss extracts may make up at most 0.1% of the finished perfume. In an eau de parfum at 18%, that is at most 0.555% of your concentrate: 0.555% of every 100 g.
Treemoss extracts is also one of the EU's declarable fragrance allergens: above 0.001% of a leave-on product it must be named on the label.
What the limit means at your strength
The limit is on the finished perfume, so the stronger the perfume, the less Treemoss extracts its concentrate can hold. If nothing else in the formula carries it:
| Perfume strength | Most Treemoss extracts in the concentrate |
|---|---|
| Cologne, 5% | 2% |
| Eau de toilette, 10% | 1% |
| 15% | 0.666% |
| Eau de parfum, 18% | 0.555% |
| 20% | 0.5% |
| Extrait, 25% | 0.4% |
What the standard says
What the limit really controls is atranol and chloroatranol: the extract must carry less than 100 ppm of them.
It shares one ceiling with Oakmoss extracts: used together, their combined total must stay under 0.1%.

A worked example
A 100 g concentrate, bottled as an eau de parfum at 18%:
| Material | Weighed |
|---|---|
| Treemoss absolute | 0.83 g |
| Ethylene Brassylate no IFRA limit | 99.17 g |
Treemoss absolute brings 0.149% Treemoss extracts to the finished perfume, against a limit of 0.1%: 1.49 times the limit. To bring it inside on its own, the calculator cuts Treemoss absolute from 0.83 g to 0.554 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 12.04%.
