PerfuMate › IFRA limits › Musk ketone
How much Musk ketone can you put in a perfume?
IFRA standard: Musk ketone · Category 4, 51st Amendment
no percentage limit
IFRA sets no percentage limit for Musk ketone in fine fragrance. Its standard is a quality specification instead: it may be used only if it holds less than 0.1% musk xylene, which is prohibited on its own.
Which materials contain Musk ketone?
Sold as Musk ketone 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 |
|---|---|
| Musk Xylol REP™ (PerfumersWorld) | 25% |
| Musk X Super™ (PerfumersWorld) | 20% |
| Fixomusk 997971D™ (Fraterworks) | 17% |
| Nitro Musk (F-TEC) | 10% |
| Krishna Musk Givco™ (Givaudan) | 3.75% |
| Broom (F-TEC) | 2.97% |
| Honey Supreme™ (Fraterworks) | 0.0008% |
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 |
|---|---|
| Musk Ketone | 20 g |
| Ethylene Brassylate no IFRA limit | 80 g |
Musk Ketone at 20 g in 100 g is 3.6% of the finished perfume. The calculator lists it as a Quality specification: it never fails a formula on the amount; what matters is the quality of the stock.
Or paste these lines into the calculator:
Musk Ketone 20 g Ethylene Brassylate 80 g
