In a press release published on December 3, 2019, the European Chemicals Agency (ECHA) announced the revision of two guidance documents that “have been updated with advice for companies preparing registration dossiers that cover nanoforms.”

The first update is to an appendix on registration and substance identification and “aligns ECHA’s guidance with the revised REACH annexes for nanomaterials that enter into application on 1 January 2020” (FPF reported). The second update is to an appendix on quantitative structure-activity relationship (QSAR) models and grouping chemicals.  It also includes guidance for the revised REACH annexes and clarifies “between creating a set of nanoforms and read-across for justifying the use of hazard data between different (sets of) nanoforms of a substance.”

ECHA says that it will continue work to update existing guidance for relevant human health and environmental information requirements during 2020.
