A worked example
A 100 g concentrate, bottled as an eau de parfum at 18%:
| Material | Weighed |
|---|---|
| Cedarwood Essential Oil Chinese | 38 g |
| Ethylene Brassylate no IFRA limit | 62 g |
Cedarwood Essential Oil Chinese brings 2.26% Cedrene to the finished perfume, against a limit of 1.5%: 1.5 times the limit. To bring it inside on its own, the calculator cuts Cedarwood Essential Oil Chinese from 38 g to 20.946 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 11.96%.

Questions
Why is Cedarwood oil limited if it is natural?
Because IFRA limits molecules, and a natural is a mixture of them. Cedarwood Essential Oil Chinese typically carries 33% Cedrene, which has its own Category 4 limit of 1.5%.
How much Cedarwood oil can I use in an eau de parfum?
At 18%, Cedarwood Essential Oil Chinese may be at most 25.2% of the concentrate, if nothing else in the formula carries Cedrene. Every other source of Cedrene counts toward the same total.
Does this limit apply to candles or soap?
No. This is Category 4, fine fragrance on skin. Other products sit in other IFRA categories with other limits, which these pages and the calculator do not cover.
