How much Isoeugenyl acetate can you put in a perfume?
IFRA standard: Isoeugenyl acetate · Category 4, 51st Amendment
0.99%
of the finished perfume, at most
Under the IFRA Standards (51st Amendment, Category 4: fine fragrance on skin), Isoeugenyl acetate may make up at most 0.99% of the finished perfume. In an eau de parfum at 18%, that is at most 5.5% of your concentrate: 5.5% of every 100 g.
What the limit means at your strength
The limit is on the finished perfume, so the stronger the perfume, the less Isoeugenyl acetate its concentrate can hold. If nothing else in the formula carries it:
| Perfume strength | Most Isoeugenyl acetate in the concentrate |
|---|---|
| Cologne, 5% | 19.8% |
| Eau de toilette, 10% | 9.9% |
| 15% | 6.6% |
| Eau de parfum, 18% | 5.5% |
| 20% | 4.95% |
| Extrait, 25% | 3.96% |
Which materials contain Isoeugenyl acetate?
Sold as Isoeugenyl acetate itself, counted in full:
It also arrives inside other materials. The limit is on the total, so the calculator adds every source together. The largest carriers in PerfuMate's catalog, by their typical composition:
| Material | Typical content | Alone at 18%, at most |
|---|---|---|
| Lotus Storm® (Fraterworks) | 2.86% | no limit on its own |
| Peru Balsam Oliffac 0912™ (IFF) | 0.09% | no limit on its own |
| Hyacinth Storm™ (Fraterworks) | 0.0012% | no limit on its own |
| Olibanum CNC™ (Fraterworks) | 0.0002% | no limit on its own |
Shares are the catalog's typical values. A real batch varies with origin and season, and your supplier's analysis (GC-MS or certificate of analysis) is the real figure.
A worked example
A 100 g concentrate, bottled as an eau de parfum at 18%:
| Material | Weighed |
|---|---|
| Isoeugenyl Acetate | 8.3 g |
| Ethylene Brassylate no IFRA limit | 91.7 g |
Isoeugenyl Acetate brings 1.49% Isoeugenyl acetate to the finished perfume, against a limit of 0.99%: 1.51 times the limit. To bring it inside on its own, the calculator cuts Isoeugenyl Acetate from 8.3 g to 5.337 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 11.92%.
Or paste these lines into the calculator:
