Upcoming GB active substance expiry dates

Biocidal products must be phased off the GB market.

The active substance/product type combinations listed are due to expire under the GB Biocidal Products Regulation (GB BPR) on the following dates:

30 November 2026

  • 1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole (propiconazole) (CAS 60207-90-1 EC 262-104-4) in product type 7
  • 5-chloro-2-(4-chlorphenoxy)phenol (DCPP) (CAS 3380-30-1 EC 429-290-0) in product types 1, 2 and 4
  • potassium (E,E)-hexa-2,4-dienoate (potassium sorbate) (CAS 24634-61-5 EC 246-376-1) in product type 18

 

28 February 2027

  • Bacillus thuringiensis subsp. kurstaki, strain ABTS-351 (CAS N/A EC N/A) in product type 18


Once the approvals expire, the active substances will no longer be able to be used in biocidal products of the relevant product types in GB.

In addition, articles treated with such products will no longer be able to be placed on the market in GB.

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 expiry of the active substance/product type combinations listed, please contact us.
