How much Acetylated Vetiver oil can you put in a perfume?
IFRA standard: Acetylated Vetiver oil · Category 4, 51st Amendment
0.9%
of the finished perfume, at most
Under the IFRA Standards (51st Amendment, Category 4: fine fragrance on skin), Acetylated Vetiver oil may make up at most 0.9% of the finished perfume. In an eau de parfum at 18%, that is at most 5% of your concentrate: 5% 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 Acetylated Vetiver oil its concentrate can hold. If nothing else in the formula carries it:
| Perfume strength | Most Acetylated Vetiver oil in the concentrate |
|---|---|
| Cologne, 5% | 18% |
| Eau de toilette, 10% | 9% |
| 15% | 6% |
| Eau de parfum, 18% | 5% |
| 20% | 4.5% |
| Extrait, 25% | 3.6% |
Which materials contain Acetylated Vetiver oil?
Sold as Acetylated Vetiver oil itself, counted in full:
It also arrives inside other materials. The limit is on the total, so the calculator adds every source together. The largest carriers in PerfuMate's catalog, by their typical composition:
| Material | Typical content | Alone at 18%, at most |
|---|---|---|
| Vetiver (F-TEC) | 25% | 20% of the concentrate |
| Fixomusk 997971D™ (Fraterworks) | 4% | no limit on its own |
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 |
|---|---|
| Vetiveryl acetate | 7.5 g |
| Ethylene Brassylate no IFRA limit | 92.5 g |
Vetiveryl acetate brings 1.35% Acetylated Vetiver oil to the finished perfume, against a limit of 0.9%: 1.5 times the limit. To bring it inside on its own, the calculator cuts Vetiveryl acetate from 7.5 g to 4.868 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 12%.
Or paste these lines into the calculator:
Vetiveryl acetate 7.5 g Ethylene Brassylate 92.5 g
