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...

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...

ECHA Publishes Final Evaluation of MWCNTs, Synthetic Graphite in Tubular Shape and Tangled
The European Chemicals Agency (ECHA) has posted the German Federal Institute for Occupational Safety and Health’s (BAuA) substance evaluation conclusion document for multi-walled carbon nanotubes (MWCNT), synthetic graphite in tubular shape and tangled. The conclusion provides a summary of how the information on the substance can be used for the purposes of regulatory risk management. Concern(s) Subject to Evaluation MWCNTs were originally selected for substance evaluation to...

ECHA Publishes Substance Evaluation Conclusion for Silver
The European Chemicals Agency (ECHA) announced on December 19, 2018, that it published several new substance evaluation conclusion documents, including one for silver. Silver was added to the Community Rolling Action Plan (CoRAP) list in 2014 and evaluated by the Netherlands. According to the substance evaluation conclusion and evaluation report, silver was originally selected for substance evaluation to clarify concerns about nanoparticles/ecotoxicity of different forms of the...

ECHA Announces RAC Concludes on Opinion for Harmonized Classification and Labeling for Titanium Dioxide
The European Chemicals Agency (ECHA) announced on September 27, 2017, that the Committee for Risk Assessment (RAC) concluded on ten opinions for harmonized classification and labeling (CLH), including titanium dioxide. In May 2016, France submitted a CLH proposal for titanium dioxide, stating that titanium dioxide should be considered as being potentially carcinogenic to humans when inhaled and thus be classified as category 1B-H350i. France proposed that the classification...

ECHA Committee Concludes Titanium Dioxide Should Be Classified as Suspected of Causing Cancer When Inhaled
On June 9, 2017, the European Chemicals Agency (ECHA) announced that the Committee for Risk Assessment (RAC) “concluded that the available scientific evidence meets the criteria in the [Classification, Labeling and Packaging (CLP)] Regulation to classify titanium dioxide as a substance suspected of causing cancer through the inhalation route.” In May 2016, France submitted a proposal for harmonized classification and labeling (CLH). The proposal’s...

Proposed Harmonized Classification and Labeling Would Apply to Nanosized Titanium Dioxide
On May 31, 2016, the European Chemicals Agency (ECHA) began a public consultation on a harmonized classification and labeling (CLH) proposal submitted by France for titanium dioxide. The proposed entry in Annex VI of the Classification, Labeling, and Packaging (CLP) Regulation is “Carc. 1B, H350i.” The CLH report states: “Based on available evidence and information in the registration dossier (e.g. mechanism of carcinogenicity, characterization of the particles), the proposed...
