RIPoN

The European Chemicals Agency's (ECHA) REACH Technical Guidance Documents until recently gave no specific guidance concerning nanomaterials. There was a technical manual on how to include information on nanomaterial in a IUCLID dossier which is an integral part of every REACH registration. This manual describes possibilities and best practices to include nanomaterials and to structure the available nanomaterial information. The latter is particularly important when nanomaterials are additional forms of a substance rather than substances in their own right. Further guidance on the clarification and elaboration of the REACH information requirements and the Chemical Safety Assessment in case of nanomaterials is needed as registration dossiers for nanomaterials must be prepared or updated by companies and reviewed by ECHA. Work in the scientific community as well as in international organisations has been ongoing for almost a decade on methodologies for assessing risks associated with nanomaterials. On this basis the Commission launched a comprehensive REACH Implementation Project on Nanomaterials (RIPoN) in 2009 to provide advice on key aspects of the implementation of REACH with regard to nanomaterials concerning Information Requirements and Chemical Safety Assessment. The two final reports are available here:

Based on the scientific and technical state of the art recommendations in these reports ECHA on 30 April 2012 published three new appendices, updating Chapters R.7a, R.7b and R.7c of the Guidance on Information Requirements and Chemical Safety Assessment (IR & CSA). These three new appendices are recommendations for registering nanomaterials.

A third report of the RIPoN project relates to Substance Identity. The final report is available but as it was not possible to reach consensus amongst the experts on the recommendations, further work of the Commission, in collaboration with CARACAL, is required before recommendations can be forwarded to ECHA.
