On January 11, 2021, the European Commission’s (EC) Scientific Committee on Consumer Safety (SCCS) posted a final opinion entitled Scientific Advice on the Safety of Nanomaterials in Cosmetics.  The EC requested that SCCS determine the nanomaterials, as published in the 2019 catalogue of nanomaterials, for which specific concerns can be identified and justified to

On April 12, 2020, the World Health Organization (WHO) published Environmental Health Criteria 244:  Principles and methods to assess the risk of immunotoxicity associated with exposure to nanomaterials.  WHO states that the document presents an overview of the current knowledge and evidence on principles and basic mechanisms of immunotoxicity caused by engineered nanomaterials (ENM). 

In May 2019, the Nordic Council of Ministers published a working paper entitled The applicability of the GHS classification criteria to nanomaterials.  The goal of the project was to review the applicability of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) to manufactured nanomaterials, taking into account the progress of international

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

On October 26, 2018, the European Commission (EC) Scientific Committee on Consumer Safety (SCCS) published its final opinion on colloidal silver (nano).  According to the final opinion, the EC received 63 notifications of cosmetic products containing colloidal silver in nano form.  The final opinion states that, according to the applicants, the ingredient is used

On September 18, 2018, the National Institute for Occupational Safety and Health (NIOSH) published a Federal Register notice announcing the availability of a draft document entitled Current Intelligence Bulletin:  Health Effects of Occupational Exposure to Silver Nanomaterials.  As reported in our January 22, 2016, blog item, NIOSH published a draft Current Intelligence Bulletin

The Silver Nanotechnology Working Group (SNWG) recently prepared a statement concerning nanosilver and its long history of safe and regulated use. SNWG notes the similarities between nanosilver and other antimicrobial silver materials available in the marketplace.  SNWG states that it “has interacted with the [U.S. Environmental Protection Agency (EPA)] in challenged exchanges on how best

The Silver Nanotechnology Working Group (SNWG) prepared a May 2, 2011, statement regarding the German Federal Institute for Risk Assessment’s (BfR) April 12, 2011, statement concerning consumer products containing nanosilver. SNWG notes that, in December 2009, BfR published an opinion advising against the use of nanosilver in consumer products. Industry and other groups, including SNWG, asked BfR

Environmental Science & Technology posted on April 5, 2011, an article entitled “Behavior of Metallic Silver Nanoparticles in a Pilot Wastewater Treatment Plant.” The abstract states:

We investigated the behavior of metallic silver nanoparticles (Ag-NP) in a pilot wastewater treatment plant (WWTP) fed with municipal wastewater.  The treatment plant consisted of a nonaerated and

In a May 25, 2010, letter to the U.S. Environmental Protection Agency (EPA) Office of Chemical Safety and Pollution Prevention (OCSPP), the Silver Nanotechnology Working Group (SNWG) expressed its concern regarding the pending Office of Pesticide Programs (OPP) interpretation concerning the regulation of nanoscale pesticide products. In its letter, SNWG states that the new interpretation, which
