How much Scentenal can you put in a perfume?
IFRA standard: Methoxy dicyclopentadiene carboxaldehyde · Category 4, 51st Amendment
1.1%
of the finished perfume, at most
Under the IFRA Standards (51st Amendment, Category 4: fine fragrance on skin), Scentenal may make up at most 1.1% of the finished perfume. In an eau de parfum at 18%, that is at most 6.11% of your concentrate: 6.11% 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 Scentenal its concentrate can hold. If nothing else in the formula carries it:
| Perfume strength | Most Scentenal in the concentrate |
|---|---|
| Cologne, 5% | 22% |
| Eau de toilette, 10% | 11% |
| 15% | 7.33% |
| Eau de parfum, 18% | 6.11% |
| 20% | 5.5% |
| Extrait, 25% | 4.4% |

Scentenal brings 1.66% Scentenal to the finished perfume, against a limit of 1.1%: 1.51 times the limit. To bring it inside on its own, the calculator cuts Scentenal from 9.2 g to 5.91 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 11.95%.
