ECETOC’s NanoApp is a tool designed to define the boundaries of sets of similar nanoforms and to generate a justification for the REACH registration.

NanoApp helps registrants follow the European Chemical Agency (ECHA)’s new registration requirements for nanomaterials under the EU’s REACH legislation. It does this by creating and justifying ‘sets of similar nanoforms’ for a joint human health and environmental hazard, exposure and safety assessment.

The tool uses established criteria and rules that systematically evaluate similarity between nanoforms. On that basis, it concludes whether a set of nanoforms can be justified or not. Its decision logic follows the ECHA guidance in a transparent and evidence-based manner – covering primarily the ‘Appendix for nanoforms applicable to the Guidance on Registration and Substance Identification’.
