ECHA Announces Plans to Update Guidance for Registration of Nanoform Substances

Lynn L. Bergeson

On February 22, 2012, the European Chemicals Agency (ECHA) issued a press release announcing that it is currently preparing an update of its Guidance on Information Requirements and Chemical Safety Assessment (IR & CSA) based on the European Commission’s Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Implementation Project on Nanomaterials (RIP-oN). Because the next registration deadline of May 31, 2013, is approaching quickly, ECHA “will facilitate compliance of all potential registrants well in advance.” ECHA intends to update the Guidance on IR & CSA later in 2012, in line with the outcomes of RIP-oNs 2 and 3. ECHA states that registrants may already find it useful to refer to the RIP-oN reports when preparing registration dossiers covering nanomaterials. ECHA reminds registrants, however, “to ensure that safe use of their substance should be demonstrated in the registration dossier, and hence that the data of the submitted properties as well as related risk assessment and management information should be applicable and appropriate for the nanoforms covered by the registration.” According to ECHA, the RIP-oN 1 report on the substance identification of nanomaterials also contains useful information that can be integrated into the IUCLID 5 manuals. Because the experience in addressing characterization of nanoforms is still developing, ECHA states it will not revise the current guidance on substance identity. Furthermore, ECHA notes, “for other areas it is clear that further scientific development and research are still necessary before providing definitive guidance updates.”
