Where can I find the list of European biocidal product authorisations?

The list is published on the website of ECHA.

The list contains all authorisations that have been issued under the Biocidal Products Regulation (and the Biocidal Products Directive) by the Member States. The list contains National authorisations of member states under the Biocidal Products Regulation as well as Union Authorisations and Simplified authorisations.
