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
Lemongrass Essential Oil	6.7 g
Ethylene Brassylate no IFRA limit	93.3 g

Lemongrass Essential Oil brings 0.904% Citral to the finished perfume, against a limit of 0.6%: 1.51 times the limit. To bring it inside on its own, the calculator cuts Lemongrass Essential Oil from 6.7 g to 4.34 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 11.94%.

Questions

Why is Lemongrass oil limited if it is natural?

Because IFRA limits molecules, and a natural is a mixture of them. Lemongrass Essential Oil typically carries 75% Citral, which has its own Category 4 limit of 0.6%.

How much Lemongrass oil can I use in an eau de parfum?

At 18%, Lemongrass Essential Oil may be at most 4.44% of the concentrate, if nothing else in the formula carries Citral. Every other source of Citral 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.
