Nanotechnologies and nanomaterials are applied in consumer products. Examples of consumer products that are claimed to contain nanoparticles or produced using nanotechnology, are the use of titanium dioxide in sunscreens, cerium oxide nanoparticles in diesel for combustion improvement and antibacterial properties of silver nanoparticles in wound dressings, textiles or large appliances.

In daily life consumers use various products which are (according to the label) produced using nanotechnology, or contain nanomaterials. Sometimes this is indeed the case, but nano can also be used as marketing instrument without proof for the use of nano. RIVMNational Institute for Public Health and the Environment has a signaling function for new developments in this area for a large audience and cooperates with a lot of other organizations. (see also nanotechnology in consumer products ). ConsExpo nano  is a tool by RIVM for assessment of potential consumer exposure to nanomaterials in consumer spray products.
