EU Fragrance Allergen Labels: An OEM Detergent Transition Guide

The placement deadline changes the question for detergent buyers

A European transition date has turned expanded fragrance-allergen labelling from a future artwork project into a current release-control issue. For OEM detergent buyers, the practical question is no longer whether a label will eventually need review. It is whether each formula, fragrance code, market language and packaging component now maps to an approved declaration. The work crosses purchasing, formulation, regulatory review, artwork, inventory and change control. A generic fragrance certificate or a supplier statement that does not identify the supplied grade and concentration is too weak for a defensible finished-product decision.

The European Commission’s detergents FAQ dated December 5, 2023 explains that detergent rules cross-refer to the cosmetics framework for fragrance-allergen labelling. It says Regulation (EU) 2023/1545 introduced 56 additional fragrance allergens and that the corresponding transition for placing products on the market ran until July 31, 2026, while qualifying products already placed on the market may be withdrawn until July 31, 2028. Those dates describe different activities. They should not be treated as a general permission to keep manufacturing new stock with old artwork.

A fragrance declaration must become a controlled label input

EUR-Lex published Commission Regulation (EU) 2023/1545 on July 26, 2023. The legal text explains why individual disclosure matters to sensitised people, updates names and groups some related substances under defined entries. It also distinguishes thresholds used for leave-on and rinse-off cosmetics. Detergent teams should not copy a cosmetics threshold table without confirming the detergent cross-reference and the product’s actual legal classification. Instead, the responsible EU operator should document the rule, threshold logic, naming convention and market-language decision applied to every SKU.

For a fragranced case such as White-Tea Liquid Laundry Detergent 5.0kg, the useful control object is a versioned bill of substances rather than a marketing scent name. The file should connect the fragrance supplier’s composition statement to the formula dosage, calculate finished-product concentrations, record grouped-name logic and generate the exact declaration used on pack and any required ingredient website. If a fragrance house changes a component, carrier, natural extract or analytical limit, the OEM must assess the label before accepting the revised material.

• Obtain a fragrance declaration tied to supplier, grade, revision and effective date.
• Calculate relevant allergen concentrations in the finished detergent, not only in the fragrance blend.
• Approve the legal name and language for each destination market before artwork release.
• Link formula, fragrance, label and packaging versions to every manufactured batch.
• Segregate old and new packaging and document the basis for any sell-through decision.

OEM teams need a market and inventory transition file

The European Commission chemicals legislation page accessed September 5, 2026 also notes that detergent labels carry ingredient and dosage information and points businesses to current legislation and implementation material. That broader framework matters because an allergen update should not accidentally displace other mandatory content, reduce legibility or create contradictions between the physical pack and online disclosure. Buyers should require a final-artwork checklist covering panel size, language, concentration-triggered names, dosage instructions and the identity of the responsible operator.

A practical transition dossier should show which units were placed on the market before the deadline, which were merely manufactured or stored, and which packaging version was used. Purchase orders should prohibit unapproved fragrance substitutions, and quality release should verify both bulk formula and packaging code. The objective is not to make every fragrance-free or scented detergent look identical. It is to ensure that claims, composition evidence and consumer-facing disclosure travel together, so a later supplier update or authority question can be answered batch by batch. The same evidence should accompany every later packaging reprint approval.
