Are there any FDA-regulated products currently on the market that employ nanotechnology?
FDA is aware of several FDA regulated products that employ nanotechnology. However, to date, few manufacturers of regulated products have claimed the use of nanotechnology in the manufacture of their products or made any nanotechnology claims for the finished product. FDA is aware that a few cosmetic products claim to contain nanoparticles to increase the stability or modify release of ingredients. Similarly FDA is aware of nanotechnology-related claims made for certain sunscreens. We are currently not aware of any safety concerns but FDA is planning additional studies to examine the effects of select nanoparticles on skin penetration.
