The International Organization for Standardization (ISO) recently published two standards for nanomaterials. ISO/TS 21633:2021, “Label-free impedance technology to assess the toxicity of nanomaterials in vitro,” describes a methodology of a label-free and real-time detection for non-invasive monitoring of cell-based assays to assess toxicity of nanomaterials to eukaryotic and prokaryotic cells. ISO/TS 23034:2021, “…

The European Food Safety Authority (EFSA) has updated its “Guidance on risk assessment of nanomaterials to be applied in the food and feed chain: human and animal health.” The updated guidance, published on August 3, 2021, covers the application areas within EFSA’s remit, including novel foods, food contact materials, food and feed additives,…

On July 15, 2021, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “The ECHA Nanomaterials Expert Group (NMEG)” by Frank Le Curieux, Scientific Area Leader for Genotoxicity at the European Chemicals Agency (ECHA). Le Curieux provides a brief summary of the creation of NMEG and its history. NMEG’s current…

Pursuant to Article 16 (10) and (11) of Regulation (EC) No 1223/2009 (Cosmetics Regulation), the European Commission (EC) is required to submit to the European Parliament and the Council an annual status report on the use of nanomaterials in cosmetic products and to review the Regulation’s provisions concerning nanomaterials. The July 22, 2021, report includes…

The European Commission’s (EC) Scientific Committee on Consumer Safety (SCCS) has begun a public comment period on its preliminary opinion on HAA299 (nano). The EC asked SCCS whether it considered HAA299 (nano) safe when used as an ultraviolet (UV) filter in cosmetic products up to a maximum concentration of ten percent. According to the…

The European Chemicals Agency (ECHA) has launched a call for tenders to perform a study “Assessment of the potential impact of graphene, graphene oxide and other 2D materials on health, and the environment” as part of the European Union (EU) Observatory for Nanomaterials (EUON). According to the description, the goal of the study…

The International Organization for Standardization (ISO) has published ISO/TR 22293:2021, “Evaluation of methods for assessing the release of nanomaterials from commercial, nanomaterial-containing polymer composites.” ISO states that an understanding of what is released from products containing manufactured nanomaterials “is critical to planning and managing safe development and use of those products.” The document…

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…

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…
