From 31 July 2026, every new cosmetic product placed on the EU market must declare 56 additional fragrance allergens — expanding the mandatory label list from 26 to 82 substances. The regulation covers synthetic and natural fragrance ingredients equally. Essential oils are specifically named. A November 2025 Corrigendum introduced three further changes — patchouli added to Annex III, Pelargonium Graveolens scope expanded, Rose ketone INCI name corrected — that many brands finalising compliance work before that date did not capture. Existing stock has a sell-through window to July 2028. But nothing new ships to EU without compliant labels from this date.
Study 1 — The Regulatory Timeline
EU Regulation 2023/1545 has been in force since August 2023. Brands were given a three-year transition to update labels and documentation. That transition ended on 31 July 2026. The November 2025 Corrigendum — published quietly, with no change to deadlines — introduced specific changes that compliance teams working from the original 2023 text may have missed.
| Date | Milestone | Status | What It Means |
|---|---|---|---|
| 26 July 2023 | Regulation EU 2023/1545 published | DONE | 3-year and 5-year transition clocks start |
| November 2025 | Corrigendum issued — 3 specific changes | MISSED BY MANY | Patchouli added. Pelargonium scope expanded. Rose ketone INCI corrected. |
| 31 July 2026 | New products deadline | IN FORCE | Any product placed on EU market must carry full 82-allergen declaration where applicable |
| 31 July 2028 | Existing stock sell-through ends | UPCOMING | Non-compliant stock already on market may sell through until this date only |

Study 2 — Essential Oils Allergen Matrix
The 82-allergen list includes individual chemical entities present naturally in essential oils. A single oil can trigger multiple allergen declarations simultaneously. Thresholds: leave-on products >0.001%; rinse-off products >0.01% in the finished product.

Study 3 — Compliance Document Checklist
Compliance with EU 2023/1545 is not a single action — it is a cascade of documentation updates across the supply chain. Every document type, the responsible party, and the precise action required.
| Document | Responsible Party | Deadline | Action Required |
|---|---|---|---|
| Product Label (INCI list) | Brand / Manufacturer | 31 Jul 2026 | Add all newly declarable allergens by name when present above threshold |
| Product Information File | Brand / Responsible Person | 31 Jul 2026 | Update to reflect new allergen declarations. Obtain updated supplier documentation. |
| Cosmetic Product Safety Report | Qualified Safety Assessor | 31 Jul 2026 | CPSR must be updated for all 82 allergens. Recalculate Margins of Safety. |
| CPNP Notification | Responsible Person | 31 Jul 2026 | Update product details in the CPNP if label changes made. |
| IFRA Certificate | F&F House / Supplier | Ongoing | Ensure certificates reference IFRA Amendment 51, not Amendment 49 or 50. |
| Supplier Allergen Declaration | Raw Material Supplier | Immediate | Request updated declarations from every fragrance ingredient supplier. GC-MS with constituent % is the gold standard. |
| Corrigendum Verification | All compliance teams | URGENT | Re-verify compliance work against November 2025 Corrigendum — not just the 2023 text. |

Study 4 — Stakeholder Action Map
Every operator in the supply chain has a specific, time-sensitive action. For producers and exporters with documented, GC-MS certified supply — this regulation is not a threat. It is a moat that narrows the field of compliant suppliers.
| Stakeholder | Risk Level | 8-Day Action |
|---|---|---|
| F&F House | CRITICAL | Audit every natural-oil-containing formula against the 82-allergen list. Verify compliance work was done against the November 2025 Corrigendum, not just the 2023 regulation. |
| Personal Care Brand | CRITICAL | New EU-bound products cannot be placed on market without compliant labels from 31 July. Begin CPNP notifications immediately for any updated products. |
| Cosmetics Manufacturer | CRITICAL | Every CPSR must be reviewed and updated to cover the full 82-allergen scope. Contact your qualified safety assessor this week. |
| Trader | HIGH | Request updated allergen declarations from every essential oil supplier before accepting new stock. GC-MS with constituent percentages is required. |
| Producer / Exporter | OPPORTUNITY | GC-MS certified, batch-specific constituent reports are exactly what buyers need to complete allergen declarations. Make this explicit in every quote. |

Analyst Note
Regulation is not the enemy of natural ingredient suppliers — it is the moat. Every compliance cycle narrows the field of suppliers who can provide what buyers actually need: batch-specific GC-MS reports, constituent percentages, allergen declarations at the individual compound level. The operators who have this infrastructure in place are not just compliant — they are the only suppliers a well-run F&F house or personal care brand can safely work with after 31 July. The 82-allergen expansion is, for documented natural ingredient suppliers, a competitive filtering event. The undocumented lose access. The documented gain it.
