The European Chemicals Agency (ECHA) announced on March 22, 2022, that the Committee for Risk Assessment (RAC) recently adopted ten opinions on harmonized classification and labeling (CLH), including an opinion for multi-walled carbon nanotubes (MWCNT). According to the annex to ECHA’s announcement, MWCNTs possess properties that make them useful for industrial applications in new or enhanced materials and products (e.g., tensile strength, electrical and thermal...
On March 17, 2022, the European Commission (EC) requested that the Scientific Committee on Consumer Safety (SCCS) prepare a scientific opinion on “hydroxyapatite (nano).” As reported in our April 13, 2021, blog item, SCCS issued a final opinion in 2021 stating that having considered the data provided, and other relevant information available in scientific literature, it “cannot conclude on the safety of the hydroxyapatite composed of rod-shaped nanoparticles for use in oral-care...
The European Union (EU) Observatory for Nanomaterials (EUON) has launched two calls for tenders to conduct studies on nanomaterials. The first call for tender is on valid in silico modeling tools and read-across approaches, including creating case studies on read-across for specific types of nanomaterials. According to the call for tender, the study proposes to examine the use of these tools for nanomaterials and to draw potential conclusions (for both regulators and industry/small-...
On March 1, 2022, NanoHarmony held the first in a series of webinars covering the different phases that an Organization for Economic Cooperation and Development (OECD) test guideline (TG) progresses through during its journey from a science-based initial idea through to use by industry to fulfill regulatory obligations. A recording of the March 1, 2022, webinar on the use of TGs in industry is now available. A short survey is available to collect stakeholder viewpoints on the...

EUON Publishes Nanopinion on How to Assess the Risks of Nanoplastics
On February 24, 2022, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Are nanoplastics hazardous? The way forward to overcome the uncertainties of risk assessment” by Dr. Anita Jemec Kokalj and Dr. Dana Kühnel about defining the criteria to evaluate which properties of nanoplastics should be reported in future studies to decrease uncertainties in their risk assessment. The authors state that nanoplastics “are complex environmental pollutants...

NanoHarmony Survey Identifies Challenges in OECD Test Guidelines Development, Will Hold Webinar on March 1
As reported in our July 9, 2021, blog item, 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. To identify difficulties arising during the development process for TGs and GDs, NanoHarmony asked stakeholders to share their experiences in a short survey. According to NanoHarmony’s...

Registration Opens for NanoEHS Webinar on “What We Know about NanoEHS: Building International Bridges”
The National Nanotechnology Initiative (NNI) will hold a webinar on “What We Know about NanoEHS: Building International Bridges” on March 1, 2022. NNI states that it has supported the emergence of an international community of collaborative researchers on the environmental, health, and safety aspects of nanomaterials (nanoEHS). According to NNI, “[b]y advancing tools, methods, and standards for robust health and safety evaluation, these cooperative efforts have furthered the safe and...

EC Notifies WTO of Draft Amendment to Cosmetics Regulation to Prohibit Certain Nanomaterials
The European Commission (EC) notified the World Trade Organization (WTO) on February 11, 2022, of a draft amendment to the Cosmetics Regulation regarding the use of certain nanomaterials in cosmetics products. The EC states that the amendment is required to enact the prohibition to use in cosmetic products certain nanomaterials for which the Scientific Committee on Consumer Safety (SCCS) identified a basis of concern. The draft amendment would revise Annex II to the Cosmetics Regulation (list...
On January 18, 2022, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “What does ‘Graphene’ really look like and why is it not ‘carbon nanotubes’” by Dr. Alberto Bianco, Dr. Maurizio Prato, and Dr. Kostas Kostarelos, of the Graphene Flagship, an EU research initiative, about graphene and why it is not the same as carbon nanotubes. The article states that in particular, the authors wish to emphasize “that ‘graphene’ as a single type of...

OECD Publishes Report on Important Issues on Risk Assessment of Manufactured Nanomaterials
The Organization for Economic Cooperation and Development (OECD) published a February 2022 report entitled Important Issues on Risk Assessment of Manufactured Nanomaterials. The report provides the current practices, challenges, and strategies for assessing the risk of manufactured nanomaterials in circumstances where data are limited, and the report states that there is a necessity for more research on specific risk assessment issues. As such, the report presents an overview of the...
