Grade by grade
Each grade in PerfuMate's catalog, read through its typical composition by the calculator's engine:
| Material | Held by | At most, of the perfume | At 18%, of the concentrate |
|---|---|---|---|
| Osmanthus Absolute | Rose ketones 1% | 4.3% | 23.8% |
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 |
|---|---|
| Osmanthus Absolute | 36 g |
| Ethylene Brassylate no IFRA limit | 64 g |
Osmanthus Absolute brings 0.0648% Rose ketones to the finished perfume, against a limit of 0.043%: 1.51 times the limit. To bring it inside on its own, the calculator cuts Osmanthus Absolute from 36 g to 20.088 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 11.94%.

Questions
Why is Osmanthus absolute limited if it is natural?
Because IFRA limits molecules, and a natural is a mixture of them. Osmanthus Absolute typically carries 1% Rose ketones, which has its own Category 4 limit of 0.043%.
How much Osmanthus absolute can I use in an eau de parfum?
At 18%, Osmanthus Absolute may be at most 23.8% of the concentrate, if nothing else in the formula carries Rose ketones. Every other source of Rose ketones 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.
