The U.S. Environmental Protection Agency (EPA) announced on July 2, 2020, that it registered NSPW Nanosilver as a new active ingredient that helps suppress odor-causing bacteria, and algae, fungus, mold, and mildew that can cause deterioration or staining in textiles.  EPA notes that NSPW Nanosilver is registered only for use in specified textiles, including fabrics, sportswear, footwear, linens, and awnings.  NSPW Nanosilver is the active ingredient in the pesticide product POLYGUARD-NSPW MASTER BATCH (Polyguard).  According to EPA, Polyguard will be formulated as a master batch, meaning that NSPW Nanosilver will be embedded within plastic beads or pellets.  EPA states that…
On June 26, 2020, the European Commission (EC) published a regulation in the Official Journal of the European Union that amends Annex II of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation.  Annex II describes the requirements for compiling safety data sheets (SDS).  The EC notes that specific requirements for nanoforms of substances took effect on January 1, 2020, and that information related to those requirements is to be provided in SDSs.  The Annex II amendments include the following provisions regarding nanoforms: If the SDS pertains to one or more nanoforms, or substances that include nanoforms, this must…
On June 25, 2020, the National Institute for Occupational Safety and Health (NIOSH) published a Nanotechnology Research Center (NTRC) Program Performance One-Pager (PPOP).  NTRC conducts research to understand the potential effects on human health of exposure to engineered nanomaterials (ENM) and develops methods to control or eliminate exposures.  According to the PPOP, NTRC’s accomplishments include conducting a survey to gather information about companies’ safety and health practices surrounding the use of ENMs to assess the impact of the NIOSH guidance.  NTRC also expanded the focus of nanotechnology to include advanced materials and manufacturing.  “What’s next” actions include: Publish the…
On June 30, 2020, from 9:00 a.m.-10:30 a.m. (EDT), the European Union (EU) NanoSafety Cluster will hold a webinar on “Immune response from occupational exposure to CNTs and nanofibres.”  The following speakers will discuss work at the U.S. Centers for Disease Control and Prevention (CDC) National Institute for Occupational Safety and Health (NIOSH) on the association of occupational exposure with ex vivo functional immune response in workers handling carbon nanotubes and carbon nanofibers (CNT/F): Matthew Dahm — CNT/F exposure assessment; Aaron Erdely — Occupational exposure and immune effects; and Mary K. Schubauer-Berigan — Cross-sectional evaluation of CNT/F workers.…
On June 9, 2020, the National Academies of Sciences, Engineering, and Medicine (National Academies) held a briefing webinar featuring its report, A Quadrennial Review of the National Nanotechnology Initiative.  During the webinar, members of the ad hoc National Academies committee discussed how U.S. nanotechnology programs compare to those in other nations, whether coordination under the National Nanotechnology Initiative (NNI) should continue, and how to improve the NNI’s research and development (R&D) strategy to enhance further U.S. economic prosperity and security.  The National Academies has posted the public briefing video and public briefing slides.…
The European Union (EU) Observatory for Nanomaterials (EUON) posted a Nanopinion on June 12, 2020, entitled “Pigments:  The oldest nanomaterials in human history facing modern day challenges.”  Dr. Heike Liewald, Managing Director, Eurocolour e.V., and Giuliana Beck, Advisor, German association of producers of pigments and fillers, describe how the introduction of nano-specific requirements in statutes has significantly increased the regulatory burden.  The authors state that while many pigments have been produced in the same way over several decades without any safety concerns, the nano-specific requirements introduced more recently have increased the reporting and safety obligations, even though the…
On June 9, 2020, the French National Agency for Food, Environmental, and Occupational Health Safety (ANSES) issued a press release, in French, proposing an inventory of manufactured nanomaterials in food.  According to ANSES, manufactured nanomaterials are used in food: As additives to improve the appearance and palatability of the product; As food contact materials to improve food packaging; and As nutrient-oriented ingredients that may be present at the nanoscale. ANSES used data published in the scientific literature to identify 37 substances used as food additives or ingredients for which it considers that the presence of nanoparticles is proven (seven…
The Nanotechnology Industries Association (NIA) began a survey on June 4, 2020, inviting commercial actors within the nanomaterials arena (producers, users, and professional providers) to contribute their organization’s perception and use of the term “Advanced Materials.”  According to NIA, there is increasing policy focus on the term “Advanced Materials,” with national governments and international frameworks starting to discuss potential safety and regulatory implications.  NIA states that “[t]his is a conversation that needs clear industrial input and must avoid the assumption that ‘Advanced Materials’ are already recognised by industry as a distinct category of materials and treated as such, with additional…
The U.S. National Nanotechnology Initiative (NNI) will hold a webinar on June 24, 2020, on “Advances in self-powered wearable sensors:  A biofuel-powered electronic skin.”  NNI states that the development and commercialization of self-powered, battery-free sensors with wireless capabilities would represent a significant step toward meeting the requirements for next-generation biosensors, medical devices, and robotics.  Dr. Wei Gao, California Institute of Technology, will discuss the development of “a flexible and fully perspiration-powered integrated electronic skin (e-skin).”  According to NNI, the e-skin “can selectively monitor key physiological parameters during prolonged physical activities and wirelessly transmit the data to the user…
The Nanotechnology Industries Association (NIA) will hold a webinar on July 7, 2020, on “Introducing the NanoHarmony project.”  Funded through Horizon 2020, NanoHarmony began on April 1, 2020.  NanoHarmony brings together 14 expert partners from ten European countries and will work alongside the Organization for Economic Cooperation and Development (OECD) and European Chemicals Agency (ECHA) to support the development of test guidelines and guidance documents for eight endpoints where nanomaterial-adapted test methods have been identified as an industrial priority.  NanoHarmony will coordinate the collection and use of available data and information to support the development of test methods…
As reported in our April 8, 2020, blog item, the National Academies of Sciences, Engineering, and Medicine (National Academies) published a prepublication copy of A Quadrennial Review of the National Nanotechnology Initiative:  Nanoscience, Applications, and Commercialization.  The National Nanotechnology Coordination Office (NNCO) asked the National Academies to form an ad hoc committee to conduct a quadrennial review of the National Nanotechnology Initiative (NNI) pursuant to the 2003 21st Century Nanotechnology Research and Development Act, which authorized the NNI to coordinate the nanotechnology-related research and development (R&D) of 26 federal agencies.  On June 9, 2020, from 1:00 p.m.-2:30 p.m.…
On May 26, 2020, the European Union (EU) NanoSafety Cluster announced the publication of the final report of the (nano) TiO2 safety communication Task Force.  The goal of the task force was to provide scientific input to the ongoing classification of titanium dioxide (TiO2).  The Task Force ran from January 2018 to January 2019, collecting information regarding the classification of TiO2 and information on TiO2 hazard potential from available scientific literature.  According to the final report, to understand and document the current state of the science on lung particle overload, a workshop was held in Edinburgh, Scotland, in April 2019…
The European Union (EU) Observatory for Nanomaterials (EUON) announced on May 20, 2020, that a recent study has analyzed existing research on whether nanomaterials used in consumer products and at workplaces are absorbed through the skin.  The study was commissioned by EUON and carried out by the RPA consortium of Triskelion and the Dutch National Institute for Public Health and the Environment (RIVM).  According to EUON, the study found that the lack of standardized, validated methods and the use of varying testing protocols make it difficult to compare results and evaluate whether nanomaterials can penetrate the skin.  EUON states that…
