New GB active substance non-renewal decision

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.


Upcoming GB active substance open invitation deadlines

Submit a notification by the deadline to keep active substances in the GB Review Programme

HSE has published open invitations (.pdf) to provide an opportunity for a person, company or task force/consortium to notify an intention to take up or take over the role of participant in the GB Review Programme for the following active substance/product type combinations.

 

Anyone wishing to support one of the active substance/product type combinations listed below in GB will need to submit a notification to HSE by the following deadlines:

  • Reaction products of 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin with chlorine (DCEMH) (CAS 89415-87-2 EC 401-570-7) in product type 11
    15 February 2025

  • Reaction products of 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin with bromine and chlorine (DCDMH) (CAS n/a EC n/a) in product type 11
    15 February 2025

If a notification to take over the role of participant is not received, these active substance/product type combinations will be subject to a GB non-approval decision. This means 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. HSE will provide separate updates on these where relevant.

 

If you are aware of any disproportionate negative impacts that are likely to arise from the non-approval of any of the active substance/product type combinations listed above, please contact us.
