Hand Sanitizer (Passover) Status: Do alcohol-based hand sanitizers require Pesach certification? Alcohol-based hand sanitizers such as Purell, typically contain at least 62% ethyl alcohol, which may possibly be chametz. However, Rav Schwartz ZT”L checked a sample of hand sanitizer and said that it is as inedible as other liquid soaps and may therefore be used on Pesach regardless of the source of alcohol.
