Commission Regulation (EU) 2023/1545 comes into force on 31 July 2026, expanding the list of fragrance allergens that must be declared individually on cosmetic labels. For R&D, regulatory, and procurement teams — including Indian exporters to EU markets — this is a formulation documentation exercise, not just a label update.
Commission Regulation (EU) 2023/1545 — which amends the EU Cosmetic Products Regulation 1223/2009 — comes into force on 31 July 2026 and significantly expands the list of fragrance substances that must be declared individually on cosmetic product labels. This is not a niche regulatory update affecting only perfumers and fragrance houses. It touches every cosmetic product category that contains fragrance compounds, essential oils, or botanicals with aromatic components: skincare, body care, shampoos, conditioners, shower gels, perfumes, and natural extract-based formulations.
The practical threshold change is specific. Under the expanded regulation, individual allergen substances must be declared on the ingredient list when they exceed 0.001% in leave-on products and 0.01% in rinse-off products. These are meaningfully lower thresholds than the previous regime, and the list of regulated substances has expanded from 26 to over 80 individual allergens — including many that appear in essential oils, botanical extracts, and natural fragrance components that brands may not have previously flagged as allergen-bearing.
For R&D and regulatory managers, procurement teams, and Indian brands exporting to EU markets, the six weeks remaining before enforcement is not a comfortable runway for a label update project. It is a compressed window for a much more demanding exercise: formulation-level allergen mapping, across every product in a portfolio, from raw material sourcing documentation through to label artwork and Product Information File consistency.
The most significant compliance risk for brands approaching this deadline is not missing it. It is discovering, at the artwork stage or during a regulatory review, that a fragrance compound, essential oil, or botanical extract in a product exceeds an allergen threshold that was not flagged in earlier documentation — because the regulatory exercise was never completed at the formulation and sourcing level.
A supplier declaration stating a product is "compliant" is not adequate documentation under this regulation. What regulators and, in the event of a market inspection or complaint, enforcement authorities will require is the actual allergen profile: the individual breakdown of every regulated substance by name and concentration in the finished product. This requires information flowing upward from ingredient suppliers through to the brand's regulatory files, not simply a blanket assurance of conformity.
For brands whose Product Information Files were assembled before this regulatory update — particularly those that relied on the previous 26-allergen list — a systematic gap exists between current documentation and what 31 July compliance requires. The most common error pattern is treating this as a label update that starts at the artwork studio, when it must start at the formulation and supplier data stage.
A technically adequate allergen compliance exercise for EU Regulation 2023/1545 involves several distinct, sequential steps that cannot be compressed without regulatory risk.
Step 1: Fragrance compound and essential oil identification. For every product, identify every ingredient that contains or may contain regulated fragrance allergens: declared fragrance compounds, essential oils, botanical extracts, hydrosols, and resins. This includes ingredients not traditionally flagged as "fragrance" by marketing, such as naturally aromatic plant extracts used for skin benefit claims.
Step 2: Allergen profile request from suppliers. For each identified ingredient, request a full allergen breakdown by regulated substance — not a general compliance statement. Supplier GC-MS data, allergen declarations using IFRA or Cosing-referenced substance identifiers, and quantitative concentration data at the concentration used in your formulation are the minimum requirements.
Step 3: Finished-product allergen calculation. Aggregate the allergen contributions from every ingredient across the finished formula, at the actual usage concentrations, to determine whether any regulated substance exceeds the applicable threshold (0.001% for leave-on, 0.01% for rinse-off). This calculation must account for each product's formulation individually — a shampoo and a leave-on serum containing the same essential oil will require separate calculations.
Step 4: INCI and label update. Only once the formulation-level allergen calculation is complete can the INCI list and label be accurately updated. Substances that exceed the threshold must be named individually on the label, in addition to the general "parfum" or "fragrance" descriptor. Substances below the threshold do not require individual declaration but must still be documented in the Product Information File.
Step 5: Product Information File consistency review. The PIF must be updated to reflect the current allergen data, the regulatory basis for the updated labelling, and the documentation trail supporting the compliance determination.
For Indian cosmetics manufacturers and brands exporting to EU markets — or producing for EU-destined private label — this regulation is a direct operational concern. EU Regulation 1223/1545 applies to all cosmetic products placed on the EU market, regardless of where they are manufactured. Indian products imported into the EU must carry compliant labels from 31 July 2026.
Indian manufacturers supplying EU customers should expect urgent requests for allergen data over the coming weeks from their European buyers. Those unable to provide a full allergen breakdown by regulated substance will face product listing pauses or labelling non-compliance at the point of market inspection.
For Indian fragrance and aroma chemical suppliers — Privi Speciality Chemicals, S H Kelkar (Keva), Oriental Aromatics, Eternis Fine Chemicals — this is also a customer-service moment: Indian brands and their EU buyers are actively requesting allergen documentation that Indian suppliers may not have previously been asked to prepare in this format. Suppliers who can deliver GC-MS allergen profiles aligned to the EU 2023/1545 substance list will differentiate themselves in the current export market.
With 31 July less than six weeks away, the priority sequence for teams that have not yet completed this exercise is clear and urgent.
Immediately request full allergen breakdowns from all fragrance and essential oil suppliers, specifically referencing the EU 2023/1545 expanded allergen list. Do not accept general compliance statements. Request quantitative data by regulated substance name.
Prioritise leave-on products. The 0.001% threshold for leave-on formulations is ten times more sensitive than the rinse-off threshold, meaning many leave-on products with essential oils or natural extracts at previously acceptable concentrations may now require individual allergen declaration.
Complete formulation-level allergen calculations before initiating any label or artwork work. Starting at the artwork stage without completed formulation data produces avoidable errors that require artwork revision and delay.
Update Product Information Files in parallel with label changes, ensuring the allergen profile documentation, the regulatory basis, and the declaration basis are all consistent and current. Regulatory inspections will look at PIF completeness, not only the label text.
For brands that cannot complete the exercise before 31 July for all products simultaneously, prioritise by product category (leave-on first), then by EU sales volume. A documented, systematic compliance plan with a clear completion timeline is a stronger position than no documentation at all.
The 31 July 2026 deadline is fixed. The formulation documentation work required to meet it is not a label project — it is a regulatory data project that happens to result in a label update. For any brand or manufacturer serving EU markets, the six weeks remaining should be treated as the closing window on a significant compliance obligation, not the beginning of a comfortable runway.
