Non-approval decision to be taken for unsupported active substance in the EU

E-bulletin - 18 March 2025

Active substance expiry dates postponed whilst the renewal evaluation is completed in the EU

For reasons beyond the control of the applicants, the approvals of the active substance/product type combinations listed were likely to expire before a decision could be taken on their renewal under the EU Biocidal Products Regulation (EU BPR).

To allow sufficient time for the renewal evaluation to be completed, a decision has been taken to postpone the expiry dates of the following approvals. This affects Northern Ireland (NI):

30 April 2025 to 31 October 2027:

• spinosad as a mixture of 50-95 % spinosyn A and 5-50 % spinosyn D (spinosad) (CAS 168316-95-8 EC 434-300-1) in product type 18

31 May 2025 to 30 November 2027:

• (RS)-α-cyano-3phenoxybenzyl-(1RS)-cis, trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (cypermethrin) (CAS 52315-07-8 EC 257-842-9) in product type 8

30 June 2025 to 31 December 2027:

• 2-bromo-ethanoic acid (bromoacetic acid) (CAS 79-08-3 EC 201-175-8) in product type 4

If you want to supply new biocidal products containing these active substances, you can still apply for EU BPR product authorisation. New products (including new trade names) must not be supplied in NI until product authorisation is granted.

HSE will provide separate updates on the renewal decisions when relevant.

Non-approval decisions to be taken for unsupported active substances in the EU

EU Review Programme industry support has been withdrawn for the active substance/product type combinations listed. Where the role of participant had not previously been taken over, no compliant notifications or dossiers were received through ECHA's open invitation process.

These active substance/product type combinations will now be subject to an EU non-approval decision. This affects Northern Ireland (NI):

• Pyrithione zinc (zinc pyrithione) (CAS 13463-41-7 EC EC 236-671-3) in product types 2 and 10
• 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
• Reaction products of 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin with chlorine (DCEMH) (CAS N/A EC N/A) in product type 11
• Chlorine dioxide (CAS 10049-04-4 EC 233-162-8) in product type 12
• 1,2-benzisothiazol-3(2H)-one (BIT) (CAS 2634-33-5 EC 220-120-9) in product type 2

Once a decision is taken, the active substances will no longer be able to be used in biocidal products of the relevant product types. In addition articles treated with such products will no longer be able to be placed on the market. HSE will provide separate updates on the decision and relevant phase-out periods.

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, please get in touch with HSE GB at:

Following an opportunity for any person, company or taskforce/consortium to support the active substance/product type combinations listed below in the EU Review Programme, no compliant notifications were received. This affects NI:

• Potassium dimethyldithiocarbamate (CAS 128-03-0 EC 204-875-1) in product types 9, 11 and 12

This active substance/product type combination will now be subject to an EU 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 NI market. HSE will provide separate updates on the decision and relevant phase-out periods.

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 HSE GB.
