HSE Biocides ebulletin

Issued: 12 July 2024

 

This ebulletin contains information on regulating biocides in Great Britain (GB). 

 

The GB Biocidal Products Regulation (GB BPR) operates independently from the EU Biocidal Products Regulation (EU BPR), which applies in Northern Ireland.

 

Separate ebulletins containing information specific to regulating biocides in Northern Ireland are issued as appropriate.

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

Upcoming GB active substance dossier submission deadline

Take action to keep your active substance in the GB Review Programme

The active substance/product type combination listed below has been successfully notified into the GB Review Programme following an open invitation. The next step is for a full active substance dossier to be submitted to HSE by the following deadline:

• N-Didecyl-N-dipolyethoxyammonium borate / didecylpolyoxethylammonium (polymeric betaine) (CAS 214710-34-6 EC n/a) in product type 8
  5 January 2025

Only the person, company or task force/consortium that successfully notified the active substance/product type combination listed above can submit a dossier. If any of these active substance/product type combinations are important to you, consider contacting the notifier to let them know. You may even be able to join them in supporting the active substance.

 

Check the list of successful notifiers.

 

If a dossier is not submitted by the deadline, this active substance/product type combination will be subject to a GB non-approval decision. This means the active substance will no longer be able to be used in biocidal products of the relevant product type 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.
