Fragrance Allergens in the EU: 81 Substances, Two Thresholds, One Capsule Challenge

Europe has finished the easy part of fragrance compliance. Since 31 July 2026, any cosmetic batch first placed on the EU market must declare fragrance allergens against a list of 81 substances, not the 26 that most ingredient systems were built around. The thresholds did not move: 0.001 percent in leave-on products, 0.01 percent in rinse-off products. Batches already on the market before that date may keep selling until 31 July 2028.

For capsule skincare the rule lands differently than it does for a serum in a 30 ml bottle. Fill weights are small, labels are tiny, and the fragrance load sits inside an anhydrous oil or cream base. That changes both the arithmetic of the threshold and the place where the declaration can physically live.

A leave-on capsule might carry 0.3 to 1.0 ml of product. A fragrance dosed at 0.2 percent of the fill contributes a very small absolute mass, so an individual allergen sitting at 3 percent of the fragrance compound lands near 6 ppm, below the 10 ppm declaration threshold. Push the fragrance to 0.6 percent and the same allergen crosses it. The threshold is decided by two numbers that live on different spec sheets: fragrance load in the base, allergen concentration in the compound.

A softgel shell cannot hold an ingredient list. The allergen declaration therefore moves to secondary packaging, which is usually a blister card, a folding carton or a leaflet. This is a design constraint, not a legal loophole: the list must be readable and stay with the product. Three consequences follow.

• Blister-only SKUs need a printed card or a carton, since a foil pocket has no room for 81 entries.
• Carton artwork should be locked after the fragrance house confirms its declaration, never before.
• Gift sets need one list per component, because each fill carries its own fragrance load.

Ask for a declaration written against the current Annex III list, not the 26-substance version still circulating in older templates. Request the maximum concentration of each declared allergen in the compound, so your team can calculate the finished product level. Confirm whether the compound changed since the previous batch. Supplier reformulation is common after a list expansion, and a switched compound can push an allergen over the threshold with no change to your brief.

Oil-based capsules need no preservative system, so the ingredient list stays short and the label is easier to control. That advantage disappears if fragrance is replaced with essential oils to support a natural claim, because several essential oils contain the same declarable allergens at far higher concentrations. The cleaner position is usually a low fragrance load with a documented declaration, plus an honest fragrance-free claim where it is literally true.

Compliance attaches to the batch, not to the SKU. Keep the invoice or delivery note showing when each batch first entered the EU market. That single piece of paperwork answers most surveillance questions, and it is the difference between selling remaining stock until 2028 and pulling it off shelves.

A capsule line is a good place to control fragrance exposure, because the fill is small, sealed and dosed precisely. It is not a place to guess.

We will reply with a formula direction, a fill size range, a shell option in plant-based or gelatin, and a run schedule that leaves room for label sign-off.
