HSE Biocides ebulletin

Issued: 26 June 2023

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.

Upcoming GB active substance expiry dates

Biocidal products must be phased off the GB market

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

• (±)-5-amino-1-(2,6-dichloro-α,α,α,-trifluoro-p-tolyl)-4-trifluoromethylsulfinylpyrazole-3-carbonitrile (1:1) (Fipronil) (CAS 120068-37-3 EC 424-610-5) in product type 18
  30 September 2023

• Polyhexamethylene biguanide hydrochloride with a mean number-average molecular weight (Mn) of 1600 and a mean polydispersity (PDI) of 1.8 (PHMB (1600;1.8)) (CAS 27083-27-8 / 32289-58-0 EC n/a) in product types 2, 3 and 11

  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.

Active substance no longer supported in GB

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.
