While many experts stand by hand-washing being the best option for reducing the transmission of germs, hand sanitizer is much more convenient and practical. And these days, when practical removal of pathogens is imperative, hand sanitizer has become quite the popular demand. As more and more people hop on board, more and more questions have come up. What exactly IS hand sanitizer? How long does it actually work for? Luckily, the team at Signitizer is here to answer all of those questions for you.
What Is Hand Sanitizer?
Also called hand antiseptic, hand sanitizers are formulas applied to the hand to expel disease-causing organisms. They are available in gel, liquid, or foam forms. These hand rubs are widely recommended for use in highly populated settings – from schools to daycare centers and health care clinics to grocery stores. While sanitizers are great at managing disease transmission, this effectiveness is based largely on alcohol percentage, contact time, and whether or not your skin was dirty before use. That being said, alcohol based sanitizers of at least 60% are found to be the MOST effective against bacteria and viruses.
How Long Does Hand Sanitizer Last After Application?
Make sure you are sitting down for this. Hand Sanitizers effectiveness is only good for two minutes after application. A recent survey found that over 50% of the American population mistakenly believed that hand sanitizers were still active after one hour! Despite the short life span, hand sanitizers are still optimal for using in a quick pinch. Those two minutes are imperative after, say, touching a door knob or shaking a hand.
Does Hand Sanitizer Expire?
Absolutely. Alcohol naturally begins to evaporate when exposed to air. And while many manufacturers work hard to create airtight containers, eventually the alcohol “escapes” over time. As this happens, the efficiency of the hand sanitizer is reduced. While reputable hand sanitizers will display an expiration date, if you can’t find one, expect the hand sanitizer to be no good after three years.
