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

In its 2011 position statement on sunscreens, the Nanodermatology Society states that it “believes that nano-based sunscreens do not pose serious health risks to consumers,” and agrees with the Environmental Working Group (EWG) that “[z]inc and titanium-based formulations are among the safest, most effective, sunscreens on the market.” According to the position statement, this is

The U.S. Environmental Protection Agency (EPA) announced in a December 13, 2010, Federal Register notice that it will hold a public information exchange meeting to receive comments and questions on the Nanomaterial Case Studies on January 4, 2011, in Research Triangle Park, North Carolina. According to EPA, the meeting will provide it an opportunity to highlight the Nanomaterial Case Studies and how EPA is using the studies as part of an ongoing process to refine a long-term research strategy to support the comprehensive environmental assessment of nanomaterials. Registration is required to attend the meeting, and EPA states that space is limited. Comments may be submitted in writing or made orally during the meeting. Written comments are due December 28, 2010. EPA intends to consider all such comments in evaluating whether or how to develop further case studies and workshops on nanomaterials. To date, EPA has published two Nanomaterial Case Studies — Nanomaterial Case Studies: Nanoscale Titanium Dioxide in Water Treatment and in Topical Sunscreen (Final), and Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray (External Review Draft).

The State Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Research and Evaluation Group (SFIREG) Pesticide Operations and Management (POM) Committee held a meeting on September 20, 2010. During the meeting, Jennifer McLain, Associate Director of the Antimicrobials Division, U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs (OPP), provided an update on EPA’s regulation of pesticides

On July 9, 2010, the American National Standards Institute (ANSI) will host a webinar to discuss draft international guidance on the labeling of manufactured nano-objects and products containing manufactured nano-objects. The European Committee for Standardization (CEN) Technical Committee (TC) 352 Nanotechnologies and the International Organization for Standardization (ISO) TC 229 Nanotechnologies are jointly developing a

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

In a March 2, 2010 letter, the Food and Drug Administration (FDA) responded to the Environmental Working Group’s (EWG) July 15, 2009, letter concerning sunscreen guidelines. EWG criticized the FDA for not having guidelines for sunscreen safety and efficacy. According to EWG, companies continue to profit by misleading consumers about the protection offered by their products. EWG

In a February 5, 2010, letter to the U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs, the Silver Nanotechnology Working Group (SNWG) provides its reactions to the recent Scientific Advisory Panel (SAP) report on nanosilver and other nanometal oxide pesticide products. In its letter, SNWG highlights a number of the statements and recommendations from the

The Silver Nanotechnology Working Group (SNWG) issued a press release regarding its presentation to the U.S. Environmental Protection Agency’s (EPA) Scientific Advisory Panel (SAP) at its November 3-6, 2009, meeting. EPA asked the SAP “to consider and review a set of scientific issues related to the assessment of hazard and exposure associated with nanosilver and other
