We had been using a harsh antibacterial hand sanitizer at work so some smart person decided it was time to try another product and after some research they came up with this one that actually has aloe vera gel in it as well. It does meet all the O.S.H.A. requirements and appears to do a pretty good job in regards to fighting off infection and bacterial problems. I did not purchase it myself and it was purchased in bulk. I believe if you broke down the price for an individual bottle which is 4 ounces it came out to about three dollars. When you work in a day program or anywhere you have much contact with the public you come to realize that something like this is pretty important to help avoid colds and such. I remember other brands that we had tried and some left a residue and also after a while you came to realize just how harsh some of them were on your hands as the redness set it. So far this one has been pretty good and its in a small enough bottle to pack away and bring anywhere with you.
