About My-Shield Hand Sanitizer my-shield Hand Sanitizer My-Shield hand sanitizer testing
In order to test my-shield, I used my children's dirty hands. These were VERY dirty hands.
First, the kids rubbed their dirty right hand all over an agar plate. Only their fingers really made contact with the plate.
Then I put 3 pumps of my-shield foam hand sanitizer onto Jon's left hand and 2 pumps onto Michael's littler left hand. I rubbed the hand sanitizer in and let it sit for 1 minute.
Then the kids rubbed their sanitized left hand onto another agar plate.
The plates were incubated for 48 hours in my warm (about 90 degrees F) incubator.
My-Shield Results
In case you are new to looking at agar plates, let me explain. The whitish/yellowish dots are colonies (or piles) of millions of bacteria. Viruses do not grow on these plates. Fungus and mold can grow on these plates. Not all types of bacteria can grow on these plates. So, just because a plate looks clean, doesn't necessarily mean that no microorganisms whatsoever were present. I also don't know what kinds of bacteria these are and whether or not they are dangerous. These experiments are still useful to compare the effectiveness of different hand sanitizers and cleaning products. If you would like to do your own experiments with agar plates, these are the agar plates that I use
As you can see, the my-shield hand sanitizer did a great job killing bacteria on the hands even though they had a lot of actual dirt on them.
I repeated the experiment on a different day, but this time I rinsed the hand sanitizer off after 1 minute. I realize that no one is going to be rinsing hand sanitizer off in real life. However, I wanted to see what the hand sanitizer did after only 1 minute. I wanted to be sure the clean agar plates were not the result of extra hand sanitizer being rubbed onto the plate and incubating with the bacteria for 48 hours. This time the kids' hands were normal looking and not filthy.
First, I rinsed my kids' "dirty" left hands under cool water for 10 seconds, and then they rubbed their dirty, wet, left hand onto an agar plate. Then I applied 2 pumps of hand sanitizer to their right hands and rubbed it in. They sat for 1 minute and then I rinsed their right hand for 10 seconds under cool water to remove extra hand sanitizer. Then they rubbed their wet right hand onto another agar plate. The plates were incubated for 48 hours.
If you would like to try my-shield hand sanitizer because it has been shown to kill a norovirus surrogate, kills c. diff spores, does well in my on my kids' hands, and is gentler on skin than alcohol hand sanitizers, you can order You can order my-shield here on Amazon. |
