Lactic Acid Biocides: EU Authorization 2026 for Manufacturers and Distributors

Key data

Manufacturers and distributors of lactic acid biocides can now operate throughout the European single market with a single authorization. The Implementing Regulation (EU) 2026/900, adopted on 24 April 2026, grants Union authorization for the family called Lactic Acid Product Family, in accordance with Regulation (EU) No 528/2012 on the marketing and use of biocidal products.

Until now, marketing these products in different EU countries could require separate national authorizations. With this Union authorization, that obstacle disappears, but in return companies must strictly comply with the conditions set out in the regulation.

What does this regulation establish?

Regulation 2026/900 grants a Union authorization for the biocide family Lactic Acid Product Family. This means that products included in this family can be marketed and used in all EU Member States under a single authorization, without obtaining individual national authorizations in each country.

The authorization is granted under Regulation (EU) No 528/2012, the European framework that regulates biocides. The conditions that authorized products must meet are:

• Labeling: must comply with the specific terms established in the authorization granted.
• Composition: products must respect the authorized composition within the Lactic Acid Product Family.
• Use restrictions: there are use limitations that must be respected and reflected in the product documentation.
• Technical data sheets and documentation: all product documentation must be updated to ensure compliance with the terms of the authorization.

These are naturally-based biocides, which facilitates their market positioning, but does not exempt them from strict compliance with regulatory conditions.

Economic and operational impact

This authorization has a dual effect for companies in the sector:

Market opportunity: the single authorization eliminates the need to obtain national authorizations in each Member State where you want to market the product. This reduces administrative costs, shortens time to market and simplifies regulatory management for companies operating or wanting to operate in several EU countries.

Obligation to adapt: companies already marketing products from the Lactic Acid Product Family must review their documentation to ensure it complies with the specific conditions of Regulation 2026/900. This includes labeling, composition and use restrictions. Failure to update documentation poses a risk of regulatory non-compliance.

For companies that were not yet operating in certain European markets, this authorization opens the door to expansion without the burden of multiple national authorization processes.

Who does it affect?

• Manufacturers of biocidal products containing lactic acid included in the Lactic Acid Product Family.
• Distributors marketing these products in one or more EU Member States.
• Professional users of lactic acid biocides who must verify that the products they use comply with the current authorization.
• Product managers and regulatory affairs in chemical, cleaning, food or health sector companies working with this family of biocides.
• Importers and exporters within the European single market handling these products.

Practical example

A Spanish company manufacturing a naturally-based disinfectant containing lactic acid, included in the Lactic Acid Product Family, wanted to expand its marketing to France, Germany and Poland. Until now, it had to obtain national authorizations in each of those countries, with the associated costs and timelines.

With Regulation 2026/900 in force since 24 April 2026, that company can market its product in all Member States under the Union authorization, without the need for additional national authorizations.

However, before launching the product in those markets, the regulatory affairs team must verify that the product's labeling, composition and use restrictions comply exactly with the conditions established in the authorization. If the current labeling does not reflect the required use restrictions, it must be updated before marketing.

What should companies do now?

1. Verify if your products are included in the Lactic Acid Product Family according to the terms of Regulation 2026/900, consulting the full authorization in the Official Journal of the EU.
2. Review current product labeling of affected products and verify that it complies with the specific conditions established in the Union authorization.
3. Update technical data sheets and product documentation to reflect the authorized composition and use restrictions required by the regulation.
4. Evaluate expansion opportunities in other Member States where you did not previously operate due to the barrier of national authorizations, taking advantage of the fact that the Union authorization is already in force.
5. Inform sales, distribution and regulatory affairs teams about changes in documentation and new marketing opportunities in the single market.
6. Consult with a biocide regulation specialist if there are doubts about the scope of the authorization conditions or about the adequacy of current products to the terms of Regulation 2026/900.
