The Food and Drug Administration is encouraging Americans to avoid hand sanitizers contaminated with 1-propanol, a toxic and potentially life-threatening alcohol when ingested. Wednesday's announcement comes on the heels of the agency's mid-June warning about hand sanitizers containing methanol, a type of wood alcohol that can be toxic when absorbed through the skin. As of Aug. 13, the FDA's list of specific hand sanitizer products to avoid, due to either 1-propanol or methanol, was up to 149 items.
