Does the hand sanitizer expire?
Just as the question is often asked, “Does hand sanitizer kill viruses?” There is also the misconception that there can be no expired hand sanitizer. Thus, it should be clarified that yes, hand sanitizer does expire.
Expired hand sanitizer is not toxic or harmful, it simply loses most of its germ-killing properties.
Thanks to the regulations imposed on hand sanitizers, most hand sanitizers include an expiration date on their packaging like any other product. The WHO (World Health Organization) recommends choosing sanitizers that last at least two years.
In addition to checking the label on the container for the expiration date of a hand sanitizer, you may also notice that an expired hand sanitizer often loses consistency and the characteristic alcohol smell. This is because alcohol evaporates over time, so it also loses its effectiveness as a sanitizer.

Therefore, surgeons wash their hands with soap and water, but a general practitioner performing a routine check-up may use hand sanitizer.
Also, it is common for visitors to patients to be asked to disinfect their hands with this gel. In addition, following the COVID-19 pandemic, many businesses have opted to offer hand sanitizing gel to their customers. This is excellent as it helps prevent cross-contamination between products.
On the other hand, if at any time there is no easy access to soap and water, disinfectant is a good replacement.
