With this latest addition to the list, the main concern for exposure is ingestion (1). In a three-year period over 60,000 children under 12 years old ingested hand sanitizer (2). 1-propanol is metabolized via the enzyme alcohol dehydrogenase to propionic acid and thereby disrupts the pH balance of the blood, while 2-propanol is metabolized with the same enzyme, however, the product is acetone leading to ketosis. Ingestion of both alcohols results in 1-propanol slowing down the breakdown of 2-proponal to acetone prolonging the sickness (3).<\/p>\n\n\n\n<p>Our previous\u00a0<a href=\"https:\/\/discover.restek.com\/blogs\/fda-issues-second-warning-on-methanol-based-hand-sanitizers\/\">blog<\/a>\u00a0addressed the recall of hand sanitizers that may contain methanol. Using the same method conditions it&#8217;s possible to analyze 1-propanol in addition to other compounds commonly found in adulterated hand sanitizer (Figure 1). Following the conditions below, we recommend eliminating 1-propanol as a co-solvent in the rinse vial and substituting acetonitrile instead. Figure 2 shows 1-propanol can be found as a contaminant in the blanks and samples.<\/p>\n\n\n\n<p><br><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/blog-fda-warns-hand-sanitizers-may-contain-1-propanol-01.png\" alt=\"diagram\" width=\"3000\" height=\"2250\" title=\"-\"><br>Figure 1: The analysis of denatured alcohol with an overlayed chromatogram of 1-propanol.
