PURELL® Advanced Hand Sanitizer

The Science Behind the Breakthrough

PURELL® Advanced Hand Sanitizer offers enhanced bacteria killing power in a formulation that makes it mild and soothing on the skin*.

The scientists at GOJO, backed by our 65 years in skin health and hand hygiene innovation, were able to develop a formulation that maximizes the impact of alcohol on bacteria. This family of products works by penetrating the membrane of the germ cell more effectively, maximizing the destructive power of the alcohol. As a result, PURELL Advanced Hand Sanitizer is proven to kill more than 99.99% of the germs on hands.

The innovation that became PURELL Advanced Hand Sanitizer was so well received by the scientific community that GOJO won the respected APIC 2011 Rutala Award for a paper devoted to the subject. And now we hand the breakthrough to you.

University Study Proves the Effectiveness of PURELL® Advanced Hand Sanitizer in Reducing the Spread of Germs1

In a scientific study conducted by the University of Arizona and released in August 2013, it was shown that, when used daily, PURELL Advanced Hand Sanitizer can significantly reduce the presence of harmful household germs, dramatically reducing the risk of getting sick.

How This Study Was Conducted

Day One – On the first day of the study, no hand sanitizer was provided to any group. Hands and household objects were measured for germ activity eight hours after the deliberate contamination to establish a baseline—the level of germ contamination that could be expected without hand sanitizer use.

Days Two and Three – On each of these days, all seven participating families were given PURELL hand sanitizing products.  A hand of one parent was deliberately contaminated with harmless bacteria called MS-2. PURELL bottles were placed in kitchens, bathrooms and nurseries, and small personal-use bottles were given to older family members for purses, pockets, backpacks, etc. Members of some families were told to sanitize once a day and the other families were told to sanitize three times daily.


Researchers traced the movement of the bacteria  through the household by measuring the amount of germs on hands and commonly touched objects in participants’ homes. It was found that for both groups (one-time and three-time PURELL user households), there was a significant 99 percent reduction in germ activity compared to the first-day measurements.
