Fragrance Allergen Labelling in the EU: A Practical Walkthrough

Key takeaways

1. Allergen declaration is triggered by the presence of specific materials above set levels in the finished product, not by the product type.
2. The declaration list comes from the formula, so it must be confirmed before label artwork is finalised.
3. The Commission's CosIng database is the practical reference for ingredient names and functions used on labels.
4. Placing a product on the EU market also brings a responsible person, a safety assessment and notification duties.
5. IFRA restrictions and EU allergen thresholds are separate systems and both must be satisfied.

Allergen labelling is one of the few areas where a small formula decision produces a visible, printed consequence. Change one material after the artwork is approved and the label is wrong, the carton is wrong, and in some markets the notification is wrong too.

The confusion around it usually comes from mixing two different rule systems. One is a set of fragrance-industry use restrictions on individual materials. The other is a labelling obligation that applies when certain materials are present in the finished cosmetic above specified levels. They overlap in practice and answer different questions.

This walkthrough sets out the order of operations, the documents that carry the answer, and the points where projects most often lose time.

Where the obligation comes from

European cosmetics rules exist to ensure that products placed on the market are safe and correctly described. Within that framework, certain fragrance materials must be named on the label when their concentration in the finished product passes the applicable level.

The scientific input behind those lists comes from the Commission's independent scientific committee, which issues opinions on consumer safety questions including fragrance allergens ^[1]. The committee's role is advisory and scientific; the legal obligation sits in the cosmetics framework that Member States apply.

Presence in the finished product is the trigger

The requirement attaches to the finished cosmetic, not to the fragrance concentrate. A material that is a minor part of the compound can still be present in the finished product at a level that requires declaration, and dilution does not remove the obligation if the level still passes the trigger.

This is why the calculation must be done on the finished formula: the fragrance load, the carrier and any other ingredients all affect the final figure.

Two rule systems, both satisfied

The International Fragrance Association publishes standards that restrict how much of a given material may be used and in which product categories ^[2]. Those restrictions are safety limits on use. The labelling obligation is a separate disclosure duty.

A formula can be fully within IFRA limits and still require an allergen declaration, and it can be under the labelling threshold and still breach a use restriction. Checking one and assuming the other is a regular source of late-stage corrections.

The label names come from a specific reference

Ingredient names on an EU cosmetic label follow the international naming convention, and the Commission maintains CosIng as the public database of cosmetic ingredients with their functions and labelling references ^[3].

Using the database as the naming source prevents the common error of printing a trade name or a supplier's internal name where the label requires the standard ingredient name. It also gives the artwork team a single authoritative spelling to work from.

Who needs which document, and at what point

The third row is the pivot. Everything before it is technical work that can be revised cheaply; everything after it is physical. If a project is running late, the declaration calculation is the last item that should be compressed, because it is the one whose mistakes cannot be fixed with an email.

The pieces buyers forget until the end

Allergen names on the label are the visible part of a wider set of obligations. Several of the others sit with the party that places the product on the EU market, which for an imported product is often a separate company rather than the manufacturer.

Getting these arranged in parallel with development, rather than after it, is usually the difference between a launch date and a revised launch date.

A responsible person established in the EU

Products placed on the EU market need a responsible person established in the Union, and the Commission's public guidance on cosmetics sets out what that role involves, including the product information file and notification before placing on the market ^[4].

For a brand outside the EU, this is a commercial appointment as much as a legal one, and it should be arranged before artwork is finalised because it may come with its own labelling requirements.

Artwork lead times are longer than they look

Bottle decoration, carton printing and label stock all have lead times, and any of them can be longer than the formulation itself. Once the declaration list is confirmed, use it to freeze every version of the text at the same time, including the carton and any secondary packaging.

A recurring error is correcting the bottle label and forgetting the carton insert, which carries the same ingredient list in many markets.

Reformulation later forces the whole loop again

If a restricted material has to be replaced after launch, the work is not only formulating. The declaration list is recalculated, the artwork is revised, and in some markets the product is re-notified. That is why the restriction review belongs early, and why a formula sitting close to a limit is worth treating as fragile.

A developer such as Xuelei fragrance house that builds formulas for several markets will normally run this assessment as part of the development file, which turns the review into a conversation rather than a separate project. The brand's job is to state which markets it intends to sell into, because that answer changes the calculation.

A working sequence for allergen-safe labelling

1. Fix the finished formula firstConfirm the fragrance load, the carrier and all functional ingredients before any declaration work begins.
2. Run restriction and declaration checks togetherAsk for both outputs in one document so the two systems are assessed against the same formula.
3. Verify names in the public ingredient databaseMatch every declared material to its standard ingredient name and pass the spelling to the artwork team.
4. Freeze all artwork versions simultaneouslyLabel, carton and insert should carry identical text and be approved in a single round.
5. Confirm the responsible person and notification pathArrange the EU-side appointment and the notification step before the print run is booked.
6. Retain the calculation with the product fileKeep the declaration calculation alongside the specification so future reformulation starts from a known baseline.
