Evonik Hydrogen Peroxide Biocides 2026: what changes in EU authorization

Key data

Companies that manufacture, distribute or professionally use Evonik hydrogen peroxide biocides have a specific obligation from 31 March 2026: to verify that their documentation reflects the updated Union authorization. The Implementing Regulation (EU) 2026/749 modifies Regulation (EU) 2023/2183 to incorporate strictly administrative changes in the authorization of the Evonik's Hydrogen Peroxide Product Family product family.

This is not a technical or toxicological change. The conditions of use, composition and safety assessment of these biocides remain unchanged. However, ignoring this update can generate documentary inconsistencies in audits, inspections or commercialization processes.

What does this regulation establish?

Regulation 2026/749 introduces administrative modifications to the Union authorization for the Evonik's Hydrogen Peroxide Product Family. Based on available data, these changes may include:

• Modifications to the authorization holder
• Update of contact data
• Changes in administrative designations

The regulation being modified is the Implementing Regulation (EU) 2023/2183, which was the text containing the original authorization of this family of biocides at European Union level.

As an EU Implementing Regulation, its application is direct and immediate in all Member States, including Spain, from 31 March 2026. It requires no national development or transposition rules.

Economic and operational impact

The direct economic impact of this modification is zero: no fees are increased, no technical requirements are modified and no new obligations for product reformulation or re-registration are imposed.

The operational impact, although limited, exists and is concentrated in one specific area: document management. Companies working with the Evonik's Hydrogen Peroxide Product Family must ensure that documents referencing the Union authorization—technical data sheets, contracts, internal records, labeling if applicable—cite the updated version of the authorization.

The cost of not doing so is not quantified in the regulation, but can materialize in:

• Inconsistencies detected in inspections by the competent authority
• Delays in commercialization or distribution processes that require accrediting the current authorization
• Need for urgent documentary review in case of audit

In terms of internal resources, documentary updating is a one-time, low-cost task if managed proactively, but can become a problem if detected in the context of an inspection or due diligence process.

Who does it affect?

This modification directly affects companies operating with Evonik's hydrogen peroxide biocides family at any point in the supply chain:

• Manufacturers that use these biocides as raw material or component in their production processes
• Distributors that market products from the Evonik's Hydrogen Peroxide Product Family in the European market
• Professional users that apply these biocides in their facilities or services (food industry, water treatment, industrial disinfection, among others)
• Compliance and regulatory affairs managers in companies in the chemical and biocides sector
• Advisors and consultants that manage biocides authorization documentation for their clients

Practical example

An industrial disinfection products distributor company that markets a biocide from the Evonik's Hydrogen Peroxide Product Family in Spain has in its document management system the reference to Regulation (EU) 2023/2183 as the basis of the Union authorization.

After Regulation 2026/749 enters into force on 31 March 2026, that reference remains valid in terms of the conditions of use and product composition, but the administrative data of the authorization holder have changed. If the company carries out a sale operation to a customer who requires accrediting the current authorization, or if it receives an inspection from the competent authority, it will have to demonstrate that it knows and applies the updated version of the authorization.

The concrete action: locate all internal and commercial documents that reference the authorization of these biocides and update the regulatory reference to include Regulation 2026/749 as a modification of 2023/2183.

What should companies do now?

1. Identify all documents that reference the Union authorization for the Evonik's Hydrogen Peroxide Product Family: technical data sheets, supply contracts, internal compliance records, labeling if applicable.
2. Update regulatory references to reflect that Regulation (EU) 2023/2183 has been modified by Implementing Regulation (EU) 2026/749, in force from 31 March 2026.
3. Verify the authorization holder's data in commercial and technical documentation, ensuring that it matches the updated data contained in Regulation 2026/749.
4. Communicate the change internally to the regulatory affairs, procurement, quality and any area that manages documentation related to these biocides teams.
5. Maintain documentary traceability: keep both the previous version (based on Regulation 2023/2183) and the updated version, to be able to accredit compliance at any time before an inspection or audit.
