On July 3, 2019, the European Union Observatory for Nanomaterials (EUON) published a database of nanomaterials known to be currently on the EU market. It was developed entirely from public data within the REACH registrations, the EU Cosmetics Regulation, and the French and Belgian national inventories of nanomaterials. The database currently contains 340 unique substances that are linked to their corresponding entry in the European Chemicals Agency’s (ECHA) chemicals database. Due to differences in the applied definitions of nanomaterials and thresholds for reporting, presence of a substance in one of the four data sources does not necessarily imply its listing by any of the others. The database makes clear which source each substance is listed within.
