FDA Provides Testing Method to Assess the Quality of Hand Sanitizer Products for Impurities
FDA is providing a laboratory testing method to assess the quality of finished hand sanitizer products. This testing method can be used to help assure hand sanitizers contain the correct ingredients and do not contain harmful levels of impurities. The testing method (with appropriate validation) can be used for hand sanitizers labeled with either alcohol (ethanol) or isopropyl alcohol (also called isopropanol or 2-propanol) as the active ingredient and can screen for potentially harmful impurities, as listed in FDA’s temporary guidances.
Testing ethanol for methanol contamination is a quality standard set by the United States Pharmacopeia (USP) for alcohol used in pharmaceuticals (including hand sanitizers) and enforced by FDA pursuant to section 501(b) of the FD&C Act. USP’s revision bulletin for alcohol and dehydrated alcohol monographs outlines this testing requirement, official as of September 1, 2020, which FDA requested to protect health care providers and consumers from using dangerous hand sanitizer products.
The agency’s investigation of contaminated hand sanitizers is ongoing.
