NanoHarmony Survey Asks Stakeholders about Their Experiences with OECD Test Guidelines and Guidance Documents
NanoHarmony aims to support the development of Organization for Economic Cooperation and Development (OECD) test guidelines (TG) and guidance documents (GD) for eight endpoints where nanomaterial-adapted test methods have been identified as a regulatory priority. NanoHarmony states that it is looking to create guidance for the development of other TGs and GDs in the future that will create a more efficient pathway to develop these. To help learn best practice in this area, the NanoHarmony...

ECHA Begins Consultation on CLH Proposal for Multi-Walled Carbon Tubes, Including Multi-Walled Carbon Nanotubes
The European Chemicals Agency (ECHA) has begun a public consultation on a harmonized classification and labeling (CLH) proposal for multi-walled carbon tubes (synthetic graphite in tubular shape) with a geometric tube diameter range ≥ 30 nanometers (nm) to < 3 micrometers (μm) and a length ≥ 5 μm and aspect ratio > 3:1, including multi-walled carbon nanotubes (MWC(N)T). The dossier submitted by Germany’s Federal Institute for Occupational Safety and Health (BAuA) states that the...
The European Commission (EC) has requested a scientific opinion from the Scientific Committee for Consumer Safety (SCCS) on fullerenes and hydroxylated fullerenes. According to the request, the EC has received 19 notifications under Article 16 of the Cosmetics Regulation for cosmetic products containing fullerenes and hydroxylated fullerenes. The request states that these ingredients “are reported in CosIng database with the function of ‘antimicrobial’ and ‘skin...
On June 26, 2019, the Council of the European Union (EU) announced that it adopted conclusions on chemicals intended to “offer political guidance on the development of a sustainable EU chemicals policy strategy.” The June 26, 2019, press release notes that the conclusions address in particular the topics of Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation, endocrine disruptors, nanomaterials, and pharmaceuticals.
