A worked example

A 100 g concentrate, bottled as an eau de parfum at 18%:

Material	Weighed
Cassia Essential Oil	2.4 g
Ethylene Brassylate no IFRA limit	97.6 g

Cassia Essential Oil brings 0.367% Cinnamaldehyde to the finished perfume, against a limit of 0.25%: 1.47 times the limit. To bring it inside on its own, the calculator cuts Cassia Essential Oil from 2.4 g to 1.621 g. Or keep the formula and bottle it weaker: the highest strength inside every limit is 12.25%.

Questions

Why is Cinnamon and cassia oil limited if it is natural?

Because IFRA limits molecules, and a natural is a mixture of them. Cassia Essential Oil typically carries 85% Cinnamaldehyde, which has its own Category 4 limit of 0.25%.

How much Cinnamon and cassia oil can I use in an eau de parfum?

At 18%, Cassia Essential Oil may be at most 1.63% of the concentrate, if nothing else in the formula carries Cinnamaldehyde. Every other source of Cinnamaldehyde 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.
