FDA issues guidance to support the responsible development of nanotechnology products
Today, three final guidances and one draft guidance were issued by the U.S. Food and Drug Administration providing greater regulatory clarity for industry on the use of nanotechnology in FDA-regulated products.
One final guidance addresses the agency’s overall approach for all products that it regulates, while the two additional final guidances and the new draft guidance provide specific guidance for the areas of foods, cosmetics and food for animals, respectively.
Nanotechnology is an emerging technology that allows scientists to create, explore and manipulate materials on a scale measured in nanometers—particles so small that they cannot be seen with a regular microscope. The technology has a broad range of potential applications, such as improving the packaging of food and altering the look and feel of cosmetics.
“Our goal remains to ensure transparent and predictable regulatory pathways, grounded in the best available science, in support of the responsible development of nanotechnology products,” said FDA Commissioner Margaret A. Hamburg, M.D. “We are taking a prudent scientific approach to assess each product on its own merits and are not making broad, general assumptions about the safety of nanotechnology products.”
The three final guidance documents reflect the FDA’s current thinking on these issues after taking into account public comment received on the corresponding draft guidance documents previously issued (draft agency guidance in 2011; and draft cosmetics and foods guidances in 2012).
The FDA does not make a categorical judgment that nanotechnology is inherently safe or harmful, and will continue to consider the specific characteristics of individual products. All four guidance documents encourage manufacturers to consult with the agency before taking their products to market. Consultations with the FDA early in the product development process help to facilitate a mutual understanding about specific scientific and regulatory issues relevant to the nanotechnology product, and help address questions related to safety, effectiveness, public health impact and/or regulatory status of the product.
The guidances are:
The guidance describes the FDA’s current thinking on the safety assessment of nanomaterials when used in cosmetic products and encourages manufacturers to consult with the FDA on test methods and data needed to support the substantiation of a product’s safety.
