The exciting and potentially benefit-laden world of nanoparticles continues to expand at rates that surpass the growth of any technology in history. Many public health leaders plead for caution and additional research into the widespread human and environmental hazards that could exist with use of nanotechnology. They worry that far too little is being done.
Many of you have written to ask how many products based on nanotech are on the market now or are close to being released for sale. It is almost impossible to know with great accuracy.
Most corporations decline to comment, citing proprietary or competitive concerns. The federal government keeps no tally, and a friend of mine in the Food and Drug Administration says that’s a major mistake that someday will “bite us in the butt.”
There is one group that is watching nanotechnology more closely than anyone else. The Project on Emerging Nanotechnologies is a partnership between the Pew Charitable Trust and the Woodrow Wilson International Center for Scholars. The project was formed in 2005 to address the social, political, and public safety aspects of nanotechnology.
The experts at the partnership acknowledge that their tallies are far from comprehensive, but they offer the best picture out there of what industry is doing with nanoparticles. And they offer the only inventory of consumer products around.
Here is one of their graphs and some of their facts:
The Consumer Products Inventory today lists 807 products, produced by 457 companies, located in 21 countries.
The inventory is growing fast: from 212 products when it was first released in March 2006, to 803 products in August 2008.
The largest category is health and fitness, including 126 cosmetics, 115 items of clothing, 153 personal care items, 83 types of sporting goods, 33 sunscreens and 40 water filters.
The inventory now includes products from many countries, including the United States, Korea, Japan, the United Kingdom, Germany, France, China, Taiwan, Australia, Israel, Finland, Mexico, Switzerland, New Zealand, Malaysia, Thailand, Sweden, Singapore, Canada, and Italy.
The Washington –based researchers say U.S. based companies are marketing the most products (426), followed by companies in Asia (227), Europe (108), and elsewhere around the world (38).
I will try to post updates often on this topic. But here is a link to browse the project’s inventory database:
