Triclosan is a controversial hand sanitizer chemical linked to endocrine disruption as well as other human health and environmental issues. It’s been linked to the spread of antibiotic-resistant bacteria, and even worse, it is not effective against viruses, which are often more likely the cause of our colds and flus than bacteria in the first place. That’s not the case for apple cider vinegar though—which is antibacterial and antiviral—and you can easily learn how to make hand sanitizer with vinegar that actually works and costs less money.
