NIOSH seeks comments from individuals, including scientists and representatives from various government agencies,…

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 project wants to hear from stakeholders about their experiences with TGs and GDs by asking people to share their experiences in a short survey.…

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 proposal comprises MWCTs that fulfill the European Union’s (EU) recommendation for a definition of nanomaterial and that, in line with the EU definition, have one external…

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 conditioning-miscellaneous’ and in the open literature as ‘antioxidants’ (scavenging ability against free radicals).” Currently, fullerenes and hydroxylated fullerenes are not regulated under the Cosmetic Regulation (EC) No. 1223/2009. The EC is concerned “because of the…

The European Commission’s (EC) Scientific Committee on Consumer Safety (SCCS) published a final opinion on June 28, 2021, on gold (nano), colloidal gold (nano), gold thioethylamino hyaluronic acid (nano), and acetyl heptapeptide-9 colloidal gold (nano). The EC asked SCCS whether the nanomaterials gold, colloidal gold, gold thioethylamino hyaluronic acid, and acetyl heptapeptide-9 colloidal gold are safe when used in leave-on skin cosmetic products according to the maximum concentrations and specifications, taking into account reasonably foreseeable exposure conditions. SCCS states that it considered all the information provided by the notifiers “and is of the opinion that it is not possible to…

On June 28, 2021, the European Commission’s (EC) Scientific Committee on Consumer Safety (SCCS) published its final opinion on platinum (nano), colloidal platinum (nano), and acetyl tetrapeptide-17 colloidal platinum (nano). The EC asked SCCS whether it considers the nanomaterials A (platinum and colloidal platinum ) and B (acetyl tetrapeptide-17 (and) colloidal platinum) safe when used in leave-on cosmetic products according to the maximum concentrations and specifications reported, taking into account reasonably foreseeable exposure conditions. Having considered the information provided by the notifiers and obtained from other sources, SCCS states that it “is of the opinion that it is not possible…

The International Organization for Standardization (ISO) has published standard ISO/TS 22292:2021, “Nanotechnologies — 3D image reconstruction of rod-supported nano-objects using transmission electron microscopy.” ISO states that the standard provides guidance for sample preparation, data acquisition by transmission electron microscopy (TEM), data processing, and three-dimensional (3D) image reconstruction to measure size and shape parameters of nano-objects on rod-shaped supports. According to ISO, the method is applicable to samples dispersed on or within an electron-transparent rod-shaped support.…

The SUSNANOFAB project, funded by the European Union’s (EU) Horizon 2020 Research and Innovation Program, is conducting a survey on industrial needs. The SUSNANOFAB project intends to create a nanofabrication ecosystem that will include an integrated roadmap of the relevant public and private initiatives at the EU level and with international cooperation. According to SUSNANOFAB, this roadmap will define a common strategy intended to enable “all pre-competitive conditions for the successful market uptake of nanofabricated products and solutions.” SUSNANOFAB is developing an Open Access digital platform that operates with existing platforms, projects, and other initiatives across Europe. SUSNANOFAB is…

On June 28, 2021, Gov4Nano will hold a workshop on the GRACIOUS approach to the quality assessment of nanosafety data. GRACIOUS, a European Union (EU) H2020 project, has proposed a methodology to facilitate the evaluation of quality and completeness for sets of nanomaterial physicochemical and (eco)toxicological data based on established criteria, i.e., completeness, reliability, relevance, and adequacy. Gov4Nano states that this approach “is unique in the sense that it can automatically assess data quality and completeness starting from the available (meta)data, thus minimising the reliance on expert judgment.” The goal is to advance further the methodology in the H2020 Gov4Nano…

On June 3, 2021, the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) published an interview with Aurélie Niaudet, who is in charge of assessing the risks associated with physical agents. Niaudet states that nanomaterials have novel properties that “are highly sought after and increasingly exploited, but can also induce specific types of behaviour when interacting with humans or the environment.” After the human body is exposed, “there is then the question of the distribution and possible accumulation of these nanomaterials in the various organs.” According to Niaudet, “assessing the risks associated with nanomaterials involves three steps:…

On May 31, 2021, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Updating our language: why we should not paint all nanoforms with the same brush” by Chiara Venturini, Director General of the Nanotechnology Industries Association (NIA). Venturini reviews how the EU’s language has evolved. In 2011, the European Commission (EC) adopted a definition that describes a nanomaterial as a material at the nanoscale. In 2020, the EC amended Annex II of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation and introduced the use of the term “nanoform” in safety data sheets…

The European Chemicals Agency (ECHA), as part of the activities of the European Union (EU) Observatory for Nanomaterials (EUON), is conducting a stakeholder survey on the substances available as nanomaterials in the EU market. The survey includes a market study of the nanomaterials, including substances, uses, volumes, and key operators in the EU. According to EUON’s May 21, 2021, news item, the survey aims to provide an overview of the substances that are available as nanomaterials on the EU market, as well as insight into their main areas of application and approximate volumes. Stakeholders are invited to complete a…
