Isoeugenol

Isoeugenol (CAS 97-54-1) is one of the fragrance allergens the European Union requires to be named on a label once it passes a threshold. It is rarely something you added on purpose: 44 materials in this catalog carry it as a constituent, which is how a formula ends up over the line without a single line item admitting to it.

What Isoeugenol smells like

Softer, sweeter and more carnation-like than eugenol, warm-spicy with powdery floral and slightly woody-vanillic depth. The heart of classic carnation accords; strongly IFRA-restricted, often replaced by Methyl Diantilis.

It is a material in its own right, not only a line on a label: its catalog page carries the full profile.

Estimates from typical published compositions, not a certificate of analysis for your bottle. A supplier's own figures always win.

PerfuMate totals these across a whole formula while you compose, counting the same molecule arriving from several materials at once, and writes the declaration for the back of the bottle. Start a formula, free. No account needed.
