Locate the transition

EU Regulation 2023/1545 expands individual fragrance allergen labelling. It allows placing products under previous provisions until 31 July 2026 and making them available until 31 July 2028, subject to its conditions. On 3 October 2026, older and newer labels can therefore coexist.

Compare the exact reference

Photograph list, batch and purchased reference. Ask whether online ingredients match that batch. A longer list does not by itself prove a formula change; separate labelling updates from product changes.

Prepare the question

For a known allergy, keep the professional’s exact name and check the precise product. Scent notes do not replace ingredients. Mark missing information and ask a specific question instead of assuming a commercial term guarantees tolerance.

Document a list difference

Keep dated photographs with each product’s reference and batch. Compare full lists rather than one isolated ingredient. State the market when contacting the manufacturer. A website consultation date does not establish manufacture or market placement of a bottle.

Deadlines on 6 October 2026

On 6 October 2026 the first deadline has passed; qualifying existing stock may remain available until 31 July 2028 under the regulation’s conditions. Two ingredient lists alone cannot date market placement. Ask the product responsible party to confirm a specific reference.

Your checklist

  • Identify market
  • Keep list and batch
  • Separate formula and label

Frequently asked questions

Does a new list mean a different perfume?

Not necessarily. Information can change without a corresponding formula change; ask the manufacturer.

Can an unofficial batch calculator prove a date?

Do not treat its result as evidence. Ask the manufacturer for batch correspondence and available information.
