Regulation (EU) 2026/1165, passed by the EU, extends data protection for certain biocidal active chemicals (pesticides, preservatives, and disinfectants) until December 31, 2030.

Reason for Extension

The new legislation, which was signed into law on May 20, 2026, by Council President Nicolas Ioannides and European Parliament President Roberta Metsola, attempts to address a regulatory bottleneck that caused chemical data owners to face inconsistent data protection periods. But the EU’s systematic review program, the massive amount of work needed to assess every biocidal active ingredient now available on the market has fallen years behind schedule. The European Commission claims that severe staffing and budget constraints, subpar initial industry applications, changing technical guidelines, and complicated new 2018 testing criteria for hormone-disrupting chemicals were the reasons why national regulatory authorities missed evaluation deadlines.

Companies that invested a lot of money to provide new safety and environmental data after 2018 faced an expiration date of December 2025 due to the delays in evaluations. This meant that compared to data created years before, their newly generated data would have a far shorter protection window.

The EU recently extended the deadline for the full biocidal evaluation program to December 31, 2030, in order to avoid this imbalance. Data protection timelines are aligned with that extension by Regulation (EU) 2026/1165.

What is Biocidal “Data Protection”?

Data protection is essentially a short-term monopoly on safety research in the regulatory world. Companies must spend millions demonstrating that a biocide is safe for both people and the environment in order to sell it in the EU.

When Data Protection is “IN” (Active): Innovators have exclusive rights to their lab data while Data Protection is “IN” (Active). Unless generic competitors pay the original data owner a substantial amount to share the study, they are prohibited from entering the market. This encourages innovation while maintaining high chemical pricing.

When Data Protection is “OUT” (Expired): The research becomes public domain after Data Protection is “OUT” (Expired). The original data can be used by generic suppliers at no cost to obtain immediate market approval. Generics flood the market and drive down prices because they have no research expenditures.

Further Impact: What Happens Next?

• Costs for Generic Suppliers: Generic suppliers on the “Article 95” list lose their free ride and are subject to immediate claims for retroactive compensation from original developers
• Delayed Market Price Drops: Limited access to lower-cost generic biocides until 2031, resulting in higher raw material costs for downstream manufacturers of cleansers, paints, and coatings.
• Protected R&D Incentives: Chemical innovators gain confidence that the EU would protect their testing investments from unnecessary delays
• Upcoming Total Overhaul (2026–2027): This extension is a temporary solution. The European Commission is starting a full review to permanently simplify the approval procedure.
