"Alcohol Free" doesn't always mean it's safe

This is a great article I was reading about the concerns of the "alcohol free" replacement many hand sanitizers use.  Benzelkonium chloride has some concerns as well but isn't as widely known as alcohol.  I feel like many companies say "alcohol free" to make you feel like it's free from chemicals but the BZK isn't a great alternative.  It's why I like to stick with soap and water!
