How much Tonka bean absolute can you put in a perfume?
2.14%
of the finished perfume, at most
By its typical composition, Tonka Bean CO2 Extract can make up at most 2.14% of a finished perfume: its Coumarin content meets that IFRA limit first. At 18% that is at most 11.9% of your concentrate.
Grades differ, and the table below has each one.
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 |
|---|---|---|---|
| Tonka bean absolute | Coumarin 65% | 2.3% | 12.8% |
| Tonka Bean CO2 Extract | Coumarin 70% | 2.14% | 11.9% |
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 |
|---|---|
| Tonka Bean CO2 Extract | 18 g |
| Ethylene Brassylate no IFRA limit | 82 g |
Tonka Bean CO2 Extract brings 2.27% Coumarin to the finished perfume, against a limit of 1.5%: 1.51 times the limit. To bring it inside on its own, the calculator cuts Tonka Bean CO2 Extract from 18 g to 11.081 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 11.9%.

Questions
Why is Tonka bean absolute limited if it is natural?
Because IFRA limits molecules, and a natural is a mixture of them. Tonka Bean CO2 Extract typically carries 70% Coumarin, which has its own Category 4 limit of 1.5%.
How much Tonka bean absolute can I use in an eau de parfum?
At 18%, Tonka Bean CO2 Extract may be at most 11.9% of the concentrate, if nothing else in the formula carries Coumarin. Every other source of Coumarin 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.
