Fragrance allergens › 3-Propylidenephthalide
3-Propylidenephthalide (CAS 17369-59-4) 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: 1 material in this catalog carries it as a constituent, which is how a formula ends up over the line without a single line item admitting to it.

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.
