Home Testing Results Refrences


Number of Bacterial Colonies Counted
Type of Hand Sanitizer Trial One Trial Two
Purell 32 39
Babyganics 47 58
Kleenex 68 61


In conclusion, my hypothesis was correct. It stated that if the top hand sanitizers are tested, then Purell would be the most effective. Purell actually was the most effective if you refer to the table above. Babyganics and Kleenex left significantly more bacterial colonies than Purell. This shows that Purell is the most effective hand sanitizer brand on the market right now.
