As nanotechnology is being used to develop new drugs, FDA is working to ensure quality, safety, and effectiveness | FDA Voice:

"Materials at the nanoscale can have different chemical, physical, or biological properties compared to their conventionally-scaled counterparts. Scientists can use these features to enhance the properties or the quality of a drug. But because such properties can affect the quality, safety, or effectiveness of a drug, FDA is studying these issues related the use of this powerful new technology in medical products."

Two draft guidance documents that address the use of nanotechnology by the food and cosmetics industries were issued today by the U.S. Food and Drug Administration.

Nanotechnology is an evolving technology that allows scientists to create, explore, and manipulate materials on a scale measured in nanometers – particles so small that they can not be seen with a regular microscope. The technology has a broad range of potential applications, such as the packaging of food or altering the look and feel of cosmetics.

Press Announcements - FDA issues draft guidance on nanotechnology:


The two draft guidance documents are: “Guidance for Industry: Assessing the Effects of Significant Manufacturing Process Changes, including Emerging Technologies, on the Safety and Regulatory Status of Food Ingredients and Food Contact Substances, Including Food Ingredients that are Color Additives” and “Guidance for Industry: Safety of Nanomaterials in Cosmetic Products.”

The food draft guidance describes the factors manufacturers should consider when determining whether changes in manufacturing processes, including those involving nanotechnology, create a significant change that may:

• affect the identity of the food substance;
• affect the safety of the use of the food substance;
• affect the regulatory status of the use of the food substance; or
• warrant a regulatory submission to FDA.

The cosmetic product draft guidance discusses the FDA’s current thinking on the safety assessment of nanomaterials when used in cosmetic products. Key points include:

• The legal requirements for cosmetics manufactured using nanomaterials are the same as those for any other cosmetics. While cosmetics are not subject to premarket approval, companies and individuals who market cosmetics are legally responsible for the safety of their products and they must be properly labeled.
• To conduct safety assessments for cosmetic products containing nanomaterials, standard safety tests may need to be modified or new methods developed.
