How much Isoeugenol can you put in a perfume?
IFRA standard: Isoeugenol · Category 4, 51st Amendment
0.11%
of the finished perfume, at most
Under the IFRA Standards (51st Amendment, Category 4: fine fragrance on skin), Isoeugenol may make up at most 0.11% of the finished perfume. In an eau de parfum at 18%, that is at most 0.611% of your concentrate: 0.611% of every 100 g.
Isoeugenol 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 Isoeugenol its concentrate can hold. If nothing else in the formula carries it:
| Perfume strength | Most Isoeugenol in the concentrate |
|---|---|
| Cologne, 5% | 2.2% |
| Eau de toilette, 10% | 1.1% |
| 15% | 0.733% |
| Eau de parfum, 18% | 0.611% |
| 20% | 0.55% |
| Extrait, 25% | 0.44% |

A worked example
A 100 g concentrate, bottled as an eau de parfum at 18%:
| Material | Weighed |
|---|---|
| Isoeugenol | 0.31 g |
| Champaca Absolute | 37 g |
| Ethylene Brassylate no IFRA limit | 62.69 g |
Isoeugenol alone brings 0.0558% Isoeugenol to the finished perfume, and Champaca Absolute adds 0.0666%. Each looks modest, but the perfume holds 0.122% against a limit of 0.11%: 1.11 times the limit. To bring it inside on its own, the calculator cuts Isoeugenol from 0.31 g to 0.263 g and Champaca Absolute from 37 g to 31.361 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 0.49%.
