What the limit means at your strength

The limit is on the finished perfume, so the stronger the perfume, the less Rose ketones its concentrate can hold. If nothing else in the formula carries it:

Perfume strength	Most Rose ketones in the concentrate
Cologne, 5%	0.86%
Eau de toilette, 10%	0.43%
15%	0.286%
Eau de parfum, 18%	0.238%
20%	0.215%
Extrait, 25%	0.172%

What the standard says

The limit covers the listed isomers and forms together, not each one on its own.

Which materials contain Rose ketones?

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
Tobacco absolutenatural	1.5%	15.9% of the concentrate
Ionone Fruity (F-TEC)	1%	23.8% of the concentrate
Mimosa Absolutenatural	1%	23.8% of the concentrate

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
alpha-Damascone	0.12 g
Tobacco absolute	9.6 g
Ethylene Brassylate no IFRA limit	90.28 g

alpha-Damascone alone brings 0.0216% Rose ketones to the finished perfume, and Tobacco absolute adds 0.0259%. Each looks modest, but the perfume holds 0.0475% against a limit of 0.043%: 1.11 times the limit. To bring it inside on its own, the calculator cuts alpha-Damascone from 0.12 g to 0.107 g and Tobacco absolute from 9.6 g to 8.594 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 16.28%.
