| Official reference | OJ:L_202601109 |
| Publication | 26 May 2026 |
| Entry into force | Not specified in the published regulation |
| Legal basis | Regulation (EU) No 528/2012 of the European Parliament and of the Council |
| Affected parties | Manufacturers, distributors and professional users of biocides with glutaraldehyde |
| Category | European Regulation |
| Affected product types | PT2, PT3, PT4, PT6, PT11, PT12 |
Manufacturers and distributors of biocides with glutaraldehyde have the green light to continue operating. Commission Implementing Decision (EU) 2026/1109, adopted by the European Commission on 22 May 2026, delays the expiration date of glutaraldehyde approval as an active substance in six types of biocide products, under the Regulation (EU) No 528/2012.
The reason is technical and administrative: the evaluation of the compound has not yet been completed. In the meantime, the regulatory framework remains the same. This avoids a legal vacuum that would have forced the withdrawal of products from the market or the suspension of operations.
What does this regulation establish?
Decision 2026/1109 extends the approval of glutaraldehyde as an active substance in biocides for the following product types:
| Product type | Use |
|---|---|
| PT2 | Disinfectants for private use |
| PT3 | Veterinary hygiene |
| PT4 | Disinfection in the food sector |
| PT6 | Preservatives for products during storage |
| PT11 | Refrigeration system fluids |
| PT12 | Slimicides (control of slimes in industrial systems) |
This extension is not a new final approval. It is a maintenance of the regulatory status quo: current conditions of use are maintained until the Commission adopts a final resolution based on the complete technical evaluation.
The decision is expressly justified because the technical evaluation of the compound has not yet been completed. This type of extension is a common mechanism under Regulation (EU) 528/2012 to prevent companies from being left in legal limbo while scientific review processes continue.
Economic and operational impact
The immediate impact for companies is neutral in terms of costs: there are no new fees, no new reformulation obligations and no need to withdraw products from the market. The extension guarantees business continuity.
However, the potential medium-term impact could be significant. The ongoing technical evaluation could conclude with one of these scenarios:
- Approval without changes: glutaraldehyde maintains its current status in all product types.
- Approval with conditions: restrictions are imposed on concentration, use, protective equipment or authorized user categories.
- Partial non-approval: authorization is withdrawn for one or more product types, requiring reformulation or discontinuation of product lines.
Companies with the greatest exposure are those whose product portfolio depends intensively on glutaraldehyde in the six affected product types, especially in the food disinfection (PT4) and industrial refrigeration fluids (PT11) segments, where substitute alternatives may require lengthy and costly validation processes.
Who does it affect?
- Biocide manufacturers that formulate products with glutaraldehyde in types PT2, PT3, PT4, PT6, PT11 or PT12.
- Distributors and marketers of these products in the European market.
- Professional users who apply biocides with glutaraldehyde: veterinary clinics, food industry, refrigeration system installers and maintainers, pest control companies and industrial slime management.
- Compliance officers in chemical, agri-food and industrial sector companies.
- Regulatory advisors and product consultants who manage biocide authorizations for their clients.
Practical example
A manufacturer of disinfectants for the food industry (PT4) that markets a product with glutaraldehyde as the active substance had pending the renewal of the approval of this substance. Without the extension, the expiration of the approval would have forced the withdrawal of the product from the market or the urgent replacement of the active substance, with the reformulation, validation and re-registration costs that this entails.
Thanks to Decision 2026/1109, that company can continue manufacturing and marketing its product without any immediate operational changes. However, its technical director or regulatory officer should already activate monitoring of the ongoing evaluation process, to anticipate with sufficient notice any restrictions that the final decision may impose.
What should companies do now?
- Verify which products in your portfolio contain glutaraldehyde and in which product types (PT2, PT3, PT4, PT6, PT11, PT12) they are classified, to understand the real scope of regulatory exposure.
- Activate monitoring of the technical evaluation process with the European Chemicals Agency (ECHA) and the European Commission, to receive alerts when advances or conclusions are published.
- Evaluate contingency scenarios: identify active substances alternative to glutaraldehyde for each affected product type, and estimate the timelines and costs of reformulation in case the final decision imposes restrictions.
- Review contracts with customers and suppliers that depend on products with glutaraldehyde, to include adaptation clauses in case of possible future regulatory changes.
- Consult with the regulatory officer or specialist advisor in biocides to assess whether it is necessary to already initiate pre-registration or validation processes of alternatives, without waiting for the final decision.
Frequently asked questions
What types of biocide products are affected by the glutaraldehyde extension?
The extension covers product types PT2 (disinfectants for private use), PT3 (veterinary hygiene), PT4 (food disinfection), PT6 (preservatives for products in storage), PT11 (refrigeration system fluids) and PT12 (slimicides).
Can they continue manufacturing and distributing biocides with glutaraldehyde after this decision?
Yes. Implementing Decision 2026/1109 allows manufacturers, distributors and professional users to continue operating without interruptions. No new restrictions or additional conditions are imposed at this time.
Why has the approval of glutaraldehyde been extended and not definitively renewed?
The extension is justified because the technical evaluation of the compound has not yet been completed. It is not a new final approval, but a maintenance of the regulatory status quo until a final decision is adopted, a mechanism provided for in Regulation (EU) No 528/2012.
When does the glutaraldehyde biocide extension come into force?
Implementing Decision 2026/1109 was published on 26 May 2026.
