The European Chemicals Agency (ECHA) is consulting on the availability of substitutes and alternatives to alphachloralose.
The EU Biocidal Products Regulation (EU BPR) applies in NI.
Under EU BPR, active substances will be considered candidates for substitution if they meet the substitution criteria set out in Article 10(1). This means that the supply and use of biocidal products containing candidates for substitution must be prohibited or restricted under EU BPR, unless all the following conditions can be shown:
- for the uses specified for that product, there are no other authorised biocidal products or existing non-chemical control or prevention methods that:
- present a significantly lower overall risk for human health, animal health and the environment
- are sufficiently effective
- present no other significant economic or practical disadvantages
- the chemical diversity of the available active substances is not adequate to minimise the occurrence of resistance in the target harmful organism
The following active substance has been identified as a potential candidate for substitution under EU BPR and ECHA has launched a public consultation to collect information on the availability of substitutes and alternatives, running until the stated date:
13 August 2026
- (R)-1,2-O-(2.2,2-trichloroethylidene)-α-D-glucofuranose (alphachloralose) (CAS 15879-93-3 EC 240-016-7) in product type 14
Comments should be submitted to ECHA (not HSE) using the dedicated webforms.
Please note this consultations and its outcome are not applicable under the GB Biocidal Products Regulations (GB BPR).
Apply for active substance renewal by the relevant deadline to keep products on the NI market.
Under EU BPR, active substance approvals will expire unless a renewal application is submitted to ECHA at least 550 days before their expiry date.
The 550-day deadlines are coming up for the following active substance/product type combinations under EU BPR. This affects NI:
28 October 2026
- calcium dihydroxide / calcium hydroxide / caustic lime / hydrated lime / slaked lime (CAS 1305-62-0 EC 215-137-3) in product types 2 and 3
- calcium magnesium oxide / dolomitic lime (CAS 37247-91-9 EC 253-425-0) in product types 2 and 3
- calcium magnesium tetrahydroxide / calcium magnesium hydroxide / hydrated dolomitic lime (CAS 39445-23-3 EC 254-454-1) in product types 2 and 3
- calcium oxide / lime / burnt lime / quicklime (CAS 1305-78-8 EC 215-138-9) in product types 2 and 3
- chlorocresol (CAS 59-50-7 EC 200-431-6) in product types 1, 2, 3, 6, 9, and 13
- coco alkyltrimethylammonium chloride (ATMAC/TMAC) (CAS 61789-18-2 EC 263-038-9) in product type 8
31 July 2027
- penflufen (CAS 494793-67-8 EC 619-823-7) in product type 8
Any person, company or task force/consortium can support an active substance/product type combination for renewal – it doesn’t have to be the original supporter.
Check the EU Article 95 List to see who the original supporters were.
If any of these active substance/product type combinations are important to you, consider contacting your supplier to let them know.
If a renewal application is not submitted for the above active substance/product type combinations under EU BPR, the approvals will expire. This means the active substances will no longer be able to be used in biocidal products of the relevant product types in NI.
In addition articles treated with such products will no longer be able to be placed on the market in NI.
