Geosil50 Authorised by UK REACH


Geosil50 was granted a Product Authorisation Certificate UK-2020-1255, under EU Biocidal Products Regulation (EU BPR) on the 16th June 2020.

Geosil50 is approved in Group 1 Disinfectants Product Type 2 “Disinfectant and algaecides not intended for direct application to humans or animals,” and Type 4 “Food and feed area.”

The existing EU Biocidal Products Regulation (EU BPR) has been copied into GB law. The new regime – the GB Biocidal Products Regulation (GB BPR) came into force at 11pm on 31 December 2020.

Geosil50 is the first, and to date, only silver stabilised hydrogen peroxide to be awarded this Authorisation anywhere in the EU or the UK.  UK HSE as the Competent Authority, had determined that Geosil met conditions detailed in Article 19 of Regulation (EU) No. 528/2012.

Now that the UK has left the EU, Geosil50 automatically complies with the GB Biocidal Products Regulation (GB BPR).

Other Silver Stabilised Hydrogen Peroxide products

It is also important to note that a product described by its vendor as “Compliant”, “Registered”, “Participating Under”, “Certified”, “Ratified by” or “HSE-recognised” does NOT mean that it has been Authorised.  Also implying that a stabilised hydrogen peroxide product is Authorised, because Hydrogen Peroxide is an approved Active Substance is deliberately misleading and inaccurate.

You can check which products are certified by reference to the HSE.

You can easily check if the biocide you are considering using is listed on the GB List of Authorised Biocidal Products. The UK list of Authorised Biocidal Products can be downloaded from the HSE website here:
