Although nanotechnology may, in the future, lead to transformative applications in various sectors of the economy—ranging from novel medicines, construction materials, and manufacturing processes, to new communication technologies, energy production and storage techniques, and water filtration devices—nanotechnology is already having a considerable impact in the consumer products sector. Nanomaterials are currently in use in a number of everyday items available for purchase in stores and through the Internet.

To track these products, the Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars developed a Consumer Products Inventory to identify and categorize the use of nanotechnology in consumer products from around the world. As of early 2009, the Consumer Products Inventory contained over 800 manufacturer-identified nanotechnology products, categorized into eight broad categories, from companies headquartered in over 20 countries. These products are designed for use in a wide range of applications, including clothing, sporting goods, home appliances, automotive products, food storage containers, and electronics and computing. The inventory is the largest single source of information on nanotechnology consumer projects publicly available. It has been used in the policy-making process to inform decision-makers about how nanotechnology is being commercialized, by interested nongovernmental stakeholders to track the evolution of information related to certain nanotechnology policy issues, and by the media, to inform the public about how nanotechnology may be impacting people's daily lives. By simultaneously acting as a policy analysis and public communications tool, the inventory has helped to engage a range of interested parties in discussions about possible risks and benefits of nanotechnology.

The Origins of the Consumer Products Inventory

The Consumer Products Inventory was developed by the Project on Emerging Nanotechnologies and was released in March 2006. The Project on Emerging Nanotechnologies is a research project, based in Washington, D.C., that was established as a partnership by the Pew Charitable Trusts, a philanthropic organization, and the Woodrow Wilson International Center for Scholars, a nonpartisan institution that analyzes domestic and global issues. The inventory was created to serve multiple purposes, including determining the number of nanotechnology consumer products available on the market, developing a tool available to the public for searching information about products that claim to use nanotechnology, and monitoring how the landscape of nanotechnology commercialization evolves over time.

Products included in the inventory generally satisfy three selection criteria. First, the products have to be readily purchasable by consumers, which excludes industrial and intermediary applications, along with drugs and medications that require a prescription. Second, the products have to be identified as based on nanotechnology by the manufacturer or another credible source, which excludes products that are suspected to be employing nanotechnology, but are not claimed as such. Third, the nanotechnology claims for the product have to appear reasonable, which excludes products that only use the phrase “nano” for marketing or advertising purposes and do not make specific claims about the use of nanotechnology.

Claims about products listed in the inventory are only based on information that can be found on the Internet. A series of mostly English language Internet searches were conducted to identify products for inclusion, and claims are reproduced from the manufacturers' Website so that the public can trace back the information to the original source. In instances where foreign language searches were conducted, the claims have been translated into English using Internet-based translation software. The inventory is not expected to function as a comprehensive listing of all nanotechnology consumer products available on the market at any particular moment. Instead, it is meant to operate as a dynamic information tool to foster public awareness of how nanotechnology is being commercialized. To this end, it is updated on a regular basis as a way to track changing commercialization patterns over time and to illuminate corresponding policy and regulatory implications that emerge from these trends.
