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

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; the reference material for lemon flavour.

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 Citral?

+

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 Citral an essential oil?

+

No. Citral 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.
