Purell, a leading brand in hand sanitizing products, is used in many hospitals and medical clinics. This Purell gel formulation contains 70% ethyl alcohol as well as aloe, vitamin E, and other moisturizers to prevent excessive drying of the skin on your hands. It is the best hand sanitizer overall.

The high level of alcohol kills germs quickly and the solution is 99.9% effective in killing contagious microbes.

The formula is free of parabens, phthalates, and preservatives that can cause skin irritation. 

There's a reason Purell has become a household name, and its Advanced Hand Sanitizer is the perfect sanitizing solution whether you're on the go, at the office, or around the house. The pump bottle version of this gel also works well to fill up smaller travel-size bottles and even fits easily into a car's cup holder.
