U.S. EPA fines Southern California technology company $208,000 for “nano coating” pesticide claims on computer peripherals - EPA, USA
The U.S. Environmental Protection Agency has settled with ATEN Technology, Inc., of Irvine, Calif., acting for its subsidiary IOGEAR, for selling unregistered pesticides and making unproven claims about their effectiveness.

EPA maintains that IOGEAR made unsubstantiated public health claims regarding unregistered products, and their ability to control germs and pathogens.

“We’re seeing far too many unregistered products that assert unsubstantiated antimicrobial properties,” said Katherine Taylor, associate director of the Communities and Ecosystems Division in EPA’s Pacific Southwest region. “Whether the claim involves use of an existing material such as silver, or new nano technology, the EPA takes these unverified public health claims very seriously. Consumers should always follow common-sense hygiene practices, like washing hands frequently and thoroughly.”

Scientists issue safety warning on cosmetic nanomaterials - EurActiv, EU
An EU scientific committee has concluded that current risk-assessment methods for nanomaterials used in cosmetics, in particular sunscreen, are not thorough enough.
The opinion also calls for the "urgent development of new methodologies to assess [the] skin penetration" of biopersistant nanomaterials which can accumulate in organs and which scientists consider more hazardous to health than the biodegradable ones, in particular with repeated application of cosmetic products.
The use of nanoparticles in sunscreen is just one example of the use of nanotechnology to improve consumer products. Other personal care products containing engineered nanomaterials such as deodorant, toothpaste, shampoo, anti-wrinkle cream or nail polish are also already commercially available despite the lack of any nanomaterials regulation or requirements for product safety testing.

Stating the Obvious: Nano Cosmetics Risk Assessment is Inadequate - Environmental Defense, USA
This Opinion was requested by the Health and Consumer Protection Directorate of the European Commission. Both its conclusions and the fact that it was requested in the first place stand in marked contrast to the present situation in the U.S., where the prevailing attitude seems to be closer to “Nothing to see here, folks. Move along….”

Nanotech Strategy: Prioritizing federal efforts for studying health and safety of nanomaterials evolves - Chemical & Engineering News, USA

Ever since manufacturers began using engineered nanomaterials in industrial processes and commercial products, some observers have raised concerns about the potential for these materials to be hazardous to human health or the environment.

These worries prompted the National Nanotechnology Initiative (NNI), the consortium of federal agencies that study or regulate nanomaterials, to devise a research strategy to answer questions about potential environmental, health, and safety (EHS) consequences of this new technology. The latest report by NNI's Nanotechnology Environmental & Health Implications (NEHI) working group—established to monitor the federal research in the field and to set agency priorities—does just that. However, some in the field say the report overstates how much EHS research is going on, particularly when it comes to human exposure studies.
