Also one of the EU’s individually declarable fragrance allergens: above 0.001% in a leave-on or 0.01% in a rinse-off product it must be named on the label.
This table shows the nine IFRA categories Alchemis maps maker products to. The full 51st Amendment defines more (fine fragrance, deodorant, hair and others) — the official standards live atifrafragrance.org.
Advisory reference, never a certification. Percentages apply to the finished product. If a supplier certificate for your blend says otherwise, the certificate wins — it accounts for the actual composition.
Alchemis checks these limits against your whole recipe automatically — per constituent, across every ingredient.
