Call for nano testing disclosure

As a new inventory of nanotechnology consumer products is released, the Royal Society has called for industry to disclose how it tests products containing nanoparticles for safety.

The inventory, produced by the US-based organisation, Woodrow Wilson International Center for Scholars, contains over 200 consumer products that use nanotechnologies, some of which are on sale in the UK. These include laptop computers, stain-resistant clothing and cosmetics such as anti-ageing creams and sunscreens.

Professor Ann Dowling, chair of the Royal Society and Royal Academy of Engineering report into nanotechnologies, said, "We can see from this inventory that nanoscience has a huge range of applications and exciting potential to improve our everyday lives."

In 2004 a major Royal Society and Royal Academy of Engineering study concluded that most nanotechnologies pose no new risks, but highlighted uncertainties about the potential effects of free nanoparticles on health and the environment.

Dowling said, "We are calling for industry to put the methods they use to test the safety of products containing free nanoparticles, such as some cosmetics, into the public domain because this is one particular area where there is some uncertainty about safety.
