Hydrochloric Acid Renewal as Biocide: What Manufacturers and Distributors Must Do in 2026

Key data

If your company manufactures, formulates or distributes industrial disinfectants containing hydrochloric acid, this regulation requires you to take action. The Commission Implementing Regulation (EU) 2026/2246, published on 13 October 2026, renews the approval of this active substance for product type 2 biocides, that is, disinfectants intended for non-domestic use: food industry, sanitary facilities, industrial cleaning and similar environments.

The renewal is not automatic for final products. Each manufacturer must review the status of its product authorizations and, if necessary, initiate the renewal process with the competent authority of its Member State. Furthermore, the updated risk assessment underlying this renewal may introduce specific conditions of use and possible restrictions that affect the formulation, labeling and technical data sheet of products in circulation.

What does this regulation establish?

Commission Implementing Regulation (EU) 2026/2246 operates within the framework of Regulation (EU) No 528/2012, the European regulation governing the marketing and use of biocides in the European Union. Its specific effect is as follows:

• The approval of hydrochloric acid as an active substance for product type 2 biocides is renewed.
• Specific conditions of use are established based on the updated risk assessment.
• Possible restrictions are introduced that manufacturers must incorporate into their formulations, technical data sheets and labeling.
• Existing product authorizations must be verified or renewed with the competent national authorities.
• Non-compliance with the new conditions may result in the withdrawal of the marketing authorization for the affected biocide product.

Product type 2 covers disinfectants and algaecides not intended for direct application to people or animals, used mainly in industrial, sanitary and food processing environments.

Economic and operational impact

The impact is not only regulatory: it has direct consequences for the operations and costs of affected companies.

• Review of product authorizations: Each commercial reference containing hydrochloric acid as an active substance in type 2 biocides must be audited internally. If the current authorization does not include the new conditions, the renewal process must be initiated, which involves administrative fees, processing time and possible reformulations.
• Update of technical data sheets and labeling: The new conditions of use and restrictions derived from the risk assessment must be reflected in the technical documentation and product labeling. This involves redesign costs, reprinting and possible withdrawal of stock with obsolete labeling.
• Risk of commercial paralysis: A product whose authorization is not aligned with the new conditions may be withdrawn from the market by the competent authorities, with the resulting impact on sales and supply contracts.
• Review of the distribution chain: Distributors must ensure that the manufacturers they work with have updated their authorizations, to avoid marketing products in an irregular situation.

Who does it affect?

• Biocide manufacturers that formulate non-domestic use disinfectant products with hydrochloric acid as the active substance.
• Distributors and marketers of these products in the European market.
• Chemical sector companies that produce or supply hydrochloric acid for use in type 2 biocide formulations.
• Industrial cleaning companies that use or supply disinfectants with this substance in industrial, food or sanitary facilities.
• Regulatory compliance managers and regulatory departments of any company with biocide products in its portfolio.
• Advisors and consultants in the chemical and industrial hygiene sector who manage the regulatory documentation of their clients.

Practical example

An industrial disinfectant manufacturer has three references of acidic cleaners for use in the food industry in its catalog, all formulated with hydrochloric acid as an active biocide substance of product type 2.

Following the publication of Commission Implementing Regulation (EU) 2026/2246, the company's regulatory manager must:

1. Review the current marketing authorizations for those three references and check whether they include the updated conditions of use.
2. If any authorization is not aligned with the new conditions, initiate the renewal procedure with the competent national authority (in Spain, the Ministry of Health through the Ministry of Health).
3. Update the technical data sheets and labeling of the products to reflect the restrictions derived from the new risk assessment.
4. Communicate the changes to distributors and industrial customers to prevent them from continuing to market or use versions with outdated documentation.

If it does not act in time, the competent authorities may withdraw the marketing authorization for those references, blocking their sale in the European market.

What should companies do now?

1. Identify all type 2 biocide products with hydrochloric acid in the commercial portfolio and in current distribution contracts.
2. Review the status of marketing authorizations for each affected reference and verify whether they remain valid under the new conditions established by Regulation 2026/2246.
3. Request the renewal of authorizations that are not aligned with the new conditions, from the competent authority of the corresponding Member State.
4. Update technical data sheets and labeling to incorporate the specific conditions of use and restrictions derived from the updated risk assessment.
5. Inform the distribution chain about changes in the technical and regulatory documentation of the affected products.
6. Establish a tracking system for renewal administrative deadlines to avoid coverage gaps that paralyze commercialization.
