In the absence of specific nanotechnology laws, existing regulatory frameworks are often applied. For example, in the United States, the Food and Drug Administration (FDA) oversees the use of nanomaterials in food, drugs, and cosmetics. The Environmental Protection Agency (EPA) regulates nanomaterials under the Toxic Substances Control Act (TSCA). Similarly, the European Union utilizes the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation to manage nanotechnology.
