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.

The U.S. Environmental Protection Agency published a proposed rule on April 1, 2020, that would amend the significant new use rules (SNUR) for certain chemical substances that were the subject of a premanufacture notice (PMN) and a significant new use notice (SNUN), including functionalized multi-walled carbon nanotubes (MWCNT) (generic).  85 Fed. Reg. 18173.  This action

On December 5, 2019, the National Toxicology Program (NTP) announced that the NTP Technical Report on the Toxicity Studies of 1020 Long Multiwalled Carbon Nanotubes Administered by Inhalation to Sprague Dawley (Hsd:Sprague Dawley® SD®) Rats and B6C3F1/N Mice is now available.  In 2003, the Rice University Center for Biological and Environmental Nanotechnology

On October 11, 2019, the U.S. Environmental Protection Agency (EPA) published proposed significant new use rules (SNUR) for 31 chemical substances, including multiwalled carbon nanotubes (generic), that were the subject of premanufacture notices (PMN).  84 Fed. Reg. 54816.  EPA notes that eight of the chemical substances are subject to orders under the Toxic Substances Control

The February 2019 issue of Computational Toxicology includes an article entitled “Grouping of multi-walled carbon nanotubes to read-across genotoxicity:  A case study to evaluate the applicability of regulatory guidance.”  The article describes a case study, performed by scientists at the European Commission’s (EC) Joint Research Center (JRC), to explore and illustrate read-across of

The U.S. Environmental Protection Agency published on October 19, 2017, a direct final rule promulgating significant new use rules (SNUR) for 29 chemical substances that were the subject of premanufacture notices (PMN).  The 29 chemical substances are subject to consent orders issued by EPA under Section 5(e) of the Toxic Substances Control Act.  The direct

On October 3, 2017, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as bimodal mixture consisting of multi-walled carbon nanotubes (MWCNT) and other classes of carbon nanotubes (CNT), which was the subject of

The International Agency for Research on Cancer (IARC) announced on May 19, 2017, publication of Volume 111 of the IARC Monographs, Some Nanomaterials and Some Fibres.  The Monograph contains evaluations of the carcinogenic hazard to humans of fluoro-edenite fibrous amphibole, silicon carbide fibers and whiskers, and carbon nanotubes.  As reported in our November 3,

Canada announced on January 9, 2015, that the New Substances Program has published six new risk assessment summaries for chemicals and polymers, including a summary for multi-wall carbon nanotubes.  Environment Canada and Health Canada conduct risk assessments on new substances.  These assessments include consideration of information on physical and chemical properties, hazards, uses, and

The U.S. Environmental Protection Agency (EPA) announced on July 2, 2012, the availability of an external review draft document entitled Nanomaterial Case Study: A Comparison of Multiwalled Carbon Nanotube and Decabromodiphenyl Ether Flame-Retardant Coatings Applied to Upholstery Textiles (EPA/600/R-12/043A). EPA states that the draft document “does not draw conclusions regarding potential environmental risks or hazards of multiwalled
