Some hand sanitizers made to meet the surge in demand amid the coronavirus pandemic contain high levels of a cancer-causing chemical known as benzene, according to a study conducted by the online pharmacy, Valisure.
Valisure analyzed 260 bottles of hand sanitizer across 168 brands in its laboratory in New Haven, Connecticut. The analysis showed that 44 bottles had detectable levels of benzene, while 21 bottles contained levels of benzene above the approved limit of two parts per million (ppm).
Valisure also detected “unacceptably high levels” of methanol and acetaldehyde. The International Agency for Research on Cancer (IARC) classifies acetaldehyde as a Group 2B carcinogen, meaning it is possibly carcinogenic to humans. Methanol is a highly toxic alcohol that can cause death if ingested.
On March 24, the pharmacy filed a citizen petition with the Food and Drug Administration (FDA) asking the agency to recall the products identified in the analysis. Valisure also asked the FDA to conduct its own analysis of hand sanitizers and to develop documents defining the limit of benzene for all hand sanitizers.
Valisure’s analysis was verified by the Chemical and Biophysical Instrumentation Center at Yale University and Boston Analytics.…
