81 Allergens, One Scent: Two EU Rulebooks for Fragrance OEMs

A brand approves one accord in March. By June it is a 50 ml eau de parfum, a 220 g candle, a 150 ml reed diffuser and an 8 ml vent clip. One smell, four legal identities. Under EU law the perfume is a cosmetic and the other three are not — and since 31 July 2026 the perfume carries a longer ingredient list than most briefs budget for.

The usual failure is sequencing. Compliance gets treated as a document request at the end of a project, when in Europe it is a formulation and artwork decision at the beginning. Annex III of the Cosmetics Regulation now lists 81 fragrance allergens, and what appears on the carton depends on the concentration in the finished product, not in the concentrate you approved.

Is perfume a cosmetic or a chemical mixture under CLP?

It is a cosmetic first. A leave-on product applied to the skin falls under Regulation (EC) No 1223/2009: a Responsible Person established in the EU, a Product Information File with a cosmetic product safety report, manufacture to ISO 22716, CPNP notification, and an ingredient list in descending order with allergens named individually once they pass 0.001% in a leave-on product. That is the label a customer reads.

The concentrate behind it is a chemical mixture, and it arrives classified under CLP (EC) No 1272/2008: a safety data sheet, a flash point, a transport class, storage rules for the filling floor. Both statements are true at the same time, and buyers get into trouble when they assume the cosmetic label replaces the CLP file. It does not. The consumer sees the cosmetic label; your warehouse, your forwarder and your filling staff see the CLP classification.

The practical consequence is to ask for both. An alcohol-based eau de parfum is normally a Class 3 flammable liquid shipped under UN 1266, and the packing group follows the flash point. Air-freighting 30 ml samples is a different exercise from sea-freighting 5,000 units, and a supplier who cannot produce the transport documents is not a supplier who can export.

Do scented candles need allergen labels in the EU?

Not an ingredient list — a candle is not applied to the body, so it sits outside the Cosmetics Regulation. It is not unregulated either. Three layers apply.

• CLP. A candle is a mixture. Where the fragrance carries a sensitiser at or above 1% (category 1 or 1B) or 0.1% (category 1A), the label needs the exclamation pictogram and H317, may cause an allergic skin reaction. Below that, EUH208 applies: contains [substance], may produce an allergic reaction. Either way the allergen is named on the pack.
• GPSR. Regulation (EU) 2023/988 has applied since 13 December 2024 to consumer products that have no sector rule of their own. It requires an EU Responsible Person named on the product or its packaging, technical documentation held for ten years, and traceability down to the batch.
• Safety standards. EN 15493 for candle safety, EN 15426 for sooting behaviour, EN 15494 for the safety markings. A buyer who asks for "EU compliant" without naming those three is asking for a feeling.

So: no ingredient list, but an allergen name, a UFI where the mixture is classified as hazardous, a responsible person and a test report. The chemistry is identical to the perfume. The paperwork is a different shape.

What changed on 31 July 2026

Commission Regulation (EU) 2023/1545 amended Annex III and added 56 fragrance allergens, taking the binding list to 81 entries, while grouping existing entries and updating their substance identifiers. The thresholds did not move: 0.001% in leave-on products, 0.01% in rinse-off products. The dates are the part that matters operationally.

Read it as: any SKU placed on the EU market after 31 July 2026 must carry the full declaration. Stock already on the market before that date may continue to be made available until 31 July 2028. A new market, a new size, a reformulation or a new brand name is a new placing on the market — which is why a formula approved in 2025 does not automatically carry a 2026 launch.

Why one concentrate produces two labels

A worked example. Take an allergen present at 0.5% in the concentrate, and dose that concentrate into each of the six formats at realistic loads.

Every figure sits between 35 and 150 times above the cosmetic threshold, so the allergen is declared in all six formats. What changes is the instrument: an ingredient list for the two cosmetic formats, a hazard statement for the four that are not cosmetics. The arithmetic is simple, and almost nobody runs it before approving artwork.

Four documents that decide the launch

Four documents carry the regulatory compliance load, and each one has a different owner. Missing any of them stalls the order at a different point.

1. A finished-product allergen declaration, calculated from a GC-MS of the concentrate dosed at the real load. A concentrate certificate is not a finished-product declaration, and a declaration copied across formats is the most common defect we see in incoming artwork.
2. An IFRA 51 certificate for the concentrate, mapped to the category that matches each format. Fine fragrance, candle, diffuser and car interior do not sit in the same IFRA category, and a restriction that passes in one may fail in another.
3. A cosmetic product safety report and Product Information File for the formats that are cosmetics — perfume, and fragrance oil where it is marketed for skin or bath use — against a GPSR technical file for the candle, diffuser, car fragrance and scent card.
4. An SDS per concentrate plus transport documents: UN 1266, packing group, limited-quantity limits, and the airline acceptance for samples.

A brief that survives the declaration

The cheapest way to control the panel is to write the constraint into the brief rather than discover it at proofing.

• Set a target: two or three named allergens per SKU, not eight. A short declaration is a design output, not luck.
• Say which formats the accord must survive. A formula tuned for 15% in alcohol will read differently at 30% in a car base, and the declaration follows the dose.
• Reserve label area at the structural design stage. Four extra lines need about 8 mm of panel height on a 50 ml carton.
• Agree who holds the Responsible Person role before the first artwork round, and put the UFI on the same proof as the ingredient list.

Where projects break

• Artwork is signed off before the declaration is confirmed, and the panel has no room left.
• The UFI is generated after the labels are printed.
• The EU Responsible Person is assumed to be the distributor, who has never agreed to it.
• One declaration file is reused across six formats because the scent is the same.
• The 2028 date is read as extra time for new SKUs rather than as sell-through for existing stock.

Each of those costs a reprint, and a reprint on a 1,000-piece run costs more than the declaration did.

What the factory has to be able to show

A perfume OEM manufacturer working across six categories cannot treat documentation as an afterthought, because the same accord is released under two regimes on the same day. On our floor the concentrate is registered once, with its IFRA certificate and SDS, and each format then pulls its own product documentation — declaration, safety file, artwork panel — from that single record, with batch traceability back to the compounding log and retained samples from every batch.

The commercial frame is deliberately low: 1,000 pieces for eau de parfum, 500 for a scented candle, 300 for fragrance oil, 500 for a reed diffuser, 2,000 for car fragrance and 5,000 for a scent card, against monthly capacity that runs from 150,000 to 2,000,000 units depending on the line. Sampling takes 7 to 10 working days, testing 5 to 10, bulk production 20 to 25 after artwork approval; a first launch lands at 14 to 18 weeks, a repeat order on existing components at 8 to 10. An in-house library of 1,800 finished formulas shortens the front end when the brief is close to something that already exists.

Certification is the part buyers audit first: GMPC and ISO 22716 for the site, IFRA 51, MSDS and a COA per batch for the goods, plus ISO 9001, FDA registration, cruelty-free and halal where the market asks for them. A private label fragrance supplier that cannot put those documents into a single pack is asking to be managed, not partnered with.

The short version

One scent, two rulebooks. The perfume needs a longer ingredient list than it did before July 2026; the candle needs a hazard statement, a UFI and a responsible person; both need a declaration calculated at the dose actually used. Deciding that at the brief stage costs a meeting. Deciding it after the labels are printed costs a run.
