The Food And Drug Administration

The Food and Drug Administration (FDA) is an agency of the United States Department of Health and Human Services and is responsible for regulating

• dietary supplements,

• drugs and cosmetics,

• biological medical products,

• dietary supplements,

• color additives in food,

• medical devices.

FDAconducts research in several of its Centers to understand the characteristics of nanomaterials and nanotechnology processes. Research interests include any areas related to the use of nanoproducts that FDA needs to consider in the regulation of these products. As an example of current research, FDA is collaborating with other agencies on studies that examine the skin absorption and phototoxicity of nano-sized titanium dioxide and zinc oxide preparations used in sunscreens. If any risks are identified, which may occur from these nano chemicals used in sunscreens, then additional tests or other requirements may be needed.

FDA only regulates certain categories of products. Existing requirements may be adequate for most nanotechnology products that we will regulate. These products are in the same size-range as the cells and molecules that FDA reviewers and scientists associate with every day.
