How much Cedrene can you put in a perfume?
IFRA standard: Cedrene · Category 4, 51st Amendment
1.5%
of the finished perfume, at most
Under the IFRA Standards (51st Amendment, Category 4: fine fragrance on skin), Cedrene may make up at most 1.5% of the finished perfume. In an eau de parfum at 18%, that is at most 8.33% of your concentrate: 8.33% 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 Cedrene its concentrate can hold. If nothing else in the formula carries it:
| Perfume strength | Most Cedrene in the concentrate |
|---|---|
| Cologne, 5% | 30% |
| Eau de toilette, 10% | 15% |
| 15% | 10% |
| Eau de parfum, 18% | 8.33% |
| 20% | 7.5% |
| Extrait, 25% | 6% |

A worked example
A 100 g concentrate, bottled as an eau de parfum at 18%:
| Material | Weighed |
|---|---|
| alpha-Cedrene | 4.2 g |
| Cedarwood Terpenes | 7.5 g |
| Ethylene Brassylate no IFRA limit | 88.3 g |
alpha-Cedrene alone brings 0.756% Cedrene to the finished perfume, and Cedarwood Terpenes adds 0.904%. Each looks modest, but the perfume holds 1.66% against a limit of 1.5%: 1.11 times the limit. To bring it inside on its own, the calculator cuts alpha-Cedrene from 4.2 g to 3.746 g and Cedarwood Terpenes from 7.5 g to 6.689 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 16.26%.
