Biocidal products must be phased off the GB market Following the applicant's withdrawal of support under the GB BPR, a decision has been taken not to renew the following active substance approval in GB: - Acrylaldehyde (Acrolein) (CAS 107-02-8 EC 203-453-4) in product type 12
As this active substance/product type combination is no longer supported for renewal, the previously postponed expiry date to allow the renewal to be carried out is no longer relevant. Therefore, the approval expiry date has changed from 28 February 2026 to 31 January 2024. If you hold an affected GB BPR product authorisation or Control of Pesticides Regulations (COPR) product approval, we will contact you about cancelling or revoking your authorisation or approval. You will have an opportunity to submit comments or additional information and we will take account of these when finalising our decision. If you are aware of any disproportionate negative impacts that are likely to arise from the non-renewal of the active substance/product type combination listed above, please contact us.
