For cleaning your hands, the CDC recommends using an alcohol-based sanitizer with no less than 60% ethanol if soap and water is not accessible. However, there is increased danger in using hand sanitizers that may contain toxic contaminants or byproducts, including methanol (AKA methyl alcohol, wood alcohol) and 1-propanol (AKA 1-propyl alcohol, n-propanol).
The FDA has issued several updates warning consumers about the use of hand sanitizers that may contain methanol or 1-propanol. On August 24, 2020, the FDA provided a modified version of the USP <467> Residual Solvents method that utilizes mass detection (MS) for impurities in hand sanitizers, and sets tentative limits for potentially harmful levels of these impurities. The method is also suitable for assaying the % alcohol content (ethanol and isopropanol) that makes hand sanitizers effective.
What changed in the modified method?
How can I get my hand sanitizer tested?
We are proud to offer testing by this new modified procedure, as well as the original USP <467> method. Please specify “FDA Hand Sanitizer Method” on your GC Analysis Request form if you would like us to test your hand sanitizer samples using the new modified procedure. Be sure to specify ethanol and/or isopropanol if you require an assay for % alcohol in your sample.
If you aren’t sure which method to use, just give us a call and we’ll walk you through the differences and help you choose what’s best for your samples.
