Regulatory & compliance
IFRA
Declared as a fragrance allergen under Annex III of EU Regulation 1223/2009. If your finished product contains this material above 0.001% in a leave-on product or 0.01% in a rinse-off product, the substance name has to appear on the label. IFRA category limits also apply and are stated on the lot-specific conformity statement.
EU 1223/2009 Annex III
This material is a named fragrance allergen in Annex III of EU Regulation 1223/2009. Declaration on the label is required above 0.001%% in leave-on products and 0.01%% in rinse-off products.
REACH and export documents
REACH registration dossier available on request for EU shipments, together with the safety data sheet and the batch certificate of analysis.
Food application
Approved food flavouring substance, though the permitted levels in food are low and category-specific.
Batch-specific values such as assay, density, refractive index, optical rotation and the full GC/MS chromatogram are issued with the certificate of analysis for the lot you receive. The values on this page are the standard profile for this material. The CAS number shown is the common main-component CAS; commercial material can be an isomer mixture, so the supplier COA is the reference.

Questions about this material
What is the minimum order quantity for Coumarin?
+
25 kg. Smaller volumes are available as samples, typically 5-10 ml, so you can evaluate the material in your own formula before ordering a full drum.
Is Coumarin an essential oil?
+
No. Coumarin is a biosynthetic aroma molecule produced by biological synthesis, and we describe it as a biosynthetic aroma raw material rather than a natural essential oil. The distinction matters for your labelling and for your customers: natural and biosynthetic materials are not interchangeable claims, even when the odour profile is.
What documentation comes with the order?
+
The batch certificate of analysis, the safety data sheet, the IFRA conformity statement naming the standard and category that applies to your product, the REACH dossier where relevant, and lot traceability back to the production batch.
How long does it take to deliver?
+
Lead time is currently 7-14 days for standard orders. We confirm the delivery date in the quotation, and we flag any capacity constraint before you place the order rather than after.
