Active Substance Expiry Date under GB BPR
Under the governance of the Great Britain Biocidal Products Regulation (GB BPR), the use of active substances in biocidal products is strictly regulated. The GB BPR requires comprehensive assessments and approvals of these substances, covering toxicology, ecotoxicology, and efficacy before products are introduced to the market. Typically, an active substance receives a 10-year validity period upon authorization under the GB BPR, which can be extended following a thorough re-evaluation.
A renewal application is required after the expiry of the active substance’s validity period, and a rigorous reassessment of its safety and effectiveness is required to justify its extended use.
This proactive measure by the HSE provides crucial breathing space for relevant stakeholders to align their product portfolios and compliance frameworks with the evolving regulatory landscape. Chemradar will closely monitor HSE’s subsequent announcements and report on relevant developments.
