From 31 July 2026, any new cosmetic or fragranced product placed on the EU and Northern Ireland market has to individually name every fragrance allergen it contains above a tiny concentration threshold, drawn from a list that has just grown from 26 substances to 81 (Regulation (EU) 2023/1545). For brands used to declaring a handful of named allergens alongside a generic “parfum” entry, that expansion turns a short ingredients line into a genuinely long one almost overnight.
This piece looks at why that regulatory change creates a real space problem on pack, and how peel and reveal formats give brands room to keep pace with it without shrinking every other piece of required label content.
What Changed in the Fragrance Allergen Rules
The expanded list replaces and updates existing entries, deletes a handful of outdated ones, and adds 45 new substances, taking the total to 81 named allergens that must appear individually in the ingredients list once present above 0.001% in leave-on products or 0.01% in rinse-off products. New products need to comply from 31 July 2026, with existing products following by 31 July 2028.
Why This Creates a Genuine Space Problem
Small format cosmetic and fragrance packaging, perfume bottles, lipsticks, travel size toiletries, was already tightly packed before this change. Adding potentially dozens of newly individually named allergens to an ingredients list that used to fit comfortably on a small back panel leaves brands choosing between font sizes that are barely legible or packaging that simply does not have room for full compliance.
How Peel and Reveal Formats Solve It
A peel and reveal label adds a hidden layer beneath the visible front panel, giving a full ingredients declaration room to breathe without enlarging the container or shrinking the brand’s front of pack design. For fragrance and cosmetic brands working through this transition, it is a way to absorb a longer allergen list without a full packaging redesign, keeping the compliance deadline manageable rather than forcing an emergency rethink of container size.
What This Means for Print and Lead Times
Moving to a peel and reveal format is a smaller production change than it might sound, since most standard labelling lines can apply a peel and reveal construction with minimal retooling, unlike a full container redesign which typically involves new tooling, new stock and a longer lead time before the change reaches shelf. For brands with a defined print schedule, building the format change into the next planned artwork update, rather than treating it as a standalone project, is usually the fastest route to compliance.
With the July 2028 deadline for existing products still ahead, brands reviewing their labels now have time to plan a peel and reveal transition properly rather than scrambling closer to the date.
