What the limit means at your strength

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

Perfume strength	Most Anisic Aldehyde in the concentrate
Cologne, 5%	28%
Eau de toilette, 10%	14%
15%	9.33%
Eau de parfum, 18%	7.77%
20%	7%
Extrait, 25%	5.6%

25 materials in the catalog carry Anisic Aldehyde; the calculator counts every one of them.

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
Anisic Aldehyde	3.9 g
Vanilla Tahitensis Absolute	39 g
Ethylene Brassylate no IFRA limit	57.1 g

Anisic Aldehyde alone brings 0.702% Anisic Aldehyde to the finished perfume, and Vanilla Tahitensis Absolute adds 0.842%. Each looks modest, but the perfume holds 1.54% against a limit of 1.4%: 1.1 times the limit. To bring it inside on its own, the calculator cuts Anisic Aldehyde from 3.9 g to 3.303 g and Vanilla Tahitensis Absolute from 39 g to 33.033 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 6.73%.
