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, “Nanotechnologies — Method to estimate cellular uptake of carbon...

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, and pesticides. The guidance takes into account relevant scientific studies on physico‐chemical properties, exposure assessment and hazard...

As reported in our January 4, 2021, blog item, the American Conference of Governmental Industrial Hygienists (ACGIH®) Threshold Limit Values for Chemical Substances (TLV®-CS) Committee included carbon nanotubes on its 2021 list of chemical substances and other issues under study. Being placed on the under study list indicated that the TLV®-CS Committee had selected carbon nanotubes for development of a threshold limit value (TLV®). ACGIH® has now released its two-tier under...

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 mandate is to provide informal and non-binding scientific and technical advice on questions related to nanomaterials or nanoforms of substances...

The January 29, 2021, issue of the U.S. Food and Drug Administration’s (FDA) NCTR Research Highlights includes an item highlighting the National Center for Toxicological Research’s (NCTR) nanotechnology-related activities in 2020.  The activities include:...

As reported in our May 7, 2021, blog item, the European Commission (EC) recently held a targeted stakeholder consultation to update, test, and verify the preliminary findings of its review of the 2011 Recommendation on the definition of a nanomaterial. According to a July 23, 2021, news item posted by the French Agency for Food, Environmental and Occupational Health and Safety (ANSES), in its response to the consultation, ANSES maintained that the changes proposed by the EC...

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 following main findings: The report states that aligning the nanomaterial definition in the Cosmetics Regulation with a...

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 preliminary opinion, SCCS considers that HAA299 (nano) as covered within the provided characteristics is safe when used as a UV filter in...

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 is to conduct a systematic literature review of the health and environmental effects of graphene, graphene oxide, and other two-dimensional (2D) materials,...

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 aims to provide a guide to the information to be taken into account in...
