30 September 2024 Once the approvals expire, the active substances can no longer be used in biocidal products of the relevant product types in Great Britain.  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 effects that are likely to arise from the expiry of any of the active substance/product type combinations listed above, please contact us. Non-approval decision to be taken for unsupported active substance in GB Following an opportunity for any person, company or taskforce/consortium to support the active substance/product type combination listed below in the GB Review Programme, no compliant notification was received: Chrysanthemum cinerariaefolium, extract from open and mature flowers of Tanacetum cinerariifolium obtained with supercritical carbon dioxide (CAS 89997-63-7 EC 289-699-3) in product type 19 In cases where active substance/product type combinations are not supported, GB biocides regulations require that these active substance/product type combinations are subject to a GB non-approval decision.  Once a decision is taken, biocidal products containing this active substance in the relevant product types will have to be removed from the GB market. HSE will provide separate updates on the decision and relevant phase-out periods.  Important: If you are aware of any disproportionate negative effects that are likely to arise from the non-approval of any of the active substance/product type combinations listed above, please contact us by 26 July 2023. |
