UK HSE Issues Notice on EU Biocides Regulation: Key Active Substances Face Non-Approval in Northern Ireland

Impact on Northern Ireland's Biocidal Market

The recent EU BPR decisions, communicated by the UK HSE, have far-reaching implications for suppliers and users of biocidal products in Northern Ireland. Key substances affected include silver adsorbed on silicon dioxide, used as a nanomaterial in product type 9, and p-[(Diiodomethyl)sulphonyl]toluene, applicable in product types 6, 7, 9, and 10. These substances can no longer be supplied after 23 December 2025 or used after 23 June 2026. Suppliers must manage their stocks to ensure compliance with these deadlines.

Actions Required for Compliance

Biocidal product suppliers must apply for EU BPR product authorisation by 1 June 2026 to continue supplying products containing the reaction products of boric acid with didecylamine and ethylene oxide in product type 8. New products cannot be introduced to the NI market until authorisation is granted. Active substance suppliers must demonstrate technical equivalence for their manufacturing sources to obtain product authorisation.

Uses and Risks of Affected Chemicals

The affected chemicals have diverse applications and associated risks. Silver adsorbed on silicon dioxide is commonly used for its antimicrobial properties in various consumer products. However, its nanoscale form raises concerns about potential environmental and health impacts. Similarly, p-[(Diiodomethyl)sulphonyl]toluene is used as a preservative and antimicrobial agent, but its use is restricted due to potential health risks.

Industry Response and Next Steps

Industry stakeholders are urged to assess the impact of these regulatory changes and take necessary actions to mitigate potential disruptions. The HSE encourages those aware of disproportionate negative impacts to contact them for further discussion. Companies must ensure compliance with the new regulations to avoid penalties and maintain market access.
