How much Dibenzyl ether can you put in a perfume?
IFRA standard: Dibenzyl ether · Category 4, 51st Amendment
0.012%
of the finished perfume, at most
Under the IFRA Standards (51st Amendment, Category 4: fine fragrance on skin), Dibenzyl ether may make up at most 0.012% of the finished perfume. In an eau de parfum at 18%, that is at most 0.0666% of your concentrate: 0.0666% 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 Dibenzyl ether its concentrate can hold. If nothing else in the formula carries it:
| Perfume strength | Most Dibenzyl ether in the concentrate |
|---|---|
| Cologne, 5% | 0.24% |
| Eau de toilette, 10% | 0.12% |
| 15% | 0.08% |
| Eau de parfum, 18% | 0.0666% |
| 20% | 0.06% |
| Extrait, 25% | 0.048% |
Which materials contain Dibenzyl ether?
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 |
|---|---|---|
| Coumarex DB™ (IFF) | 91.6% | 0.0727% of the concentrate |
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.
