The European Chemicals Agency (ECHA) has published an update to the Appendix for nanoforms applicable to the Guidance on Registration and Substance Identification (version 2.0).

The main changes, which are limited to sections 2 and 5 of the document, cover additional guidance on the joint submission of data; clarifications regarding the need for one dataset per nanoform or set of nanoforms; and information on the registration of sets of nanoforms versus single nanoforms.
