“GFS BioProtect is one of the few hand sanitizers that has actually been tested and shown to kill a norovirus surrogate. It killed 99% of murine norovirus. It is also the ONLY hand sanitizer that I’m aware of that works against a norovirus surrogate AND does not contain alcohol, and therefore, doesn’t sting hands. You all know that I love my Zylast antiseptic but in the winter my hands are cracked and bleeding. I often simply don’t use my hand sanitizer at all because it hurts too bad. I was excited about testing this non-stinging option. The BioProtect also smells really good.”

Note: GFS Bio-Protect has changed it’s name to “my-shield”

my-shield® Hand Sanitizer Foam is a alcohol free formula unique, fast acting product that forms a protective antimicrobial barrier on your hands, offering long lasting protection against germs while gently moisturizing your skin.

Up to 4 hours protection against harmful germs – my-shield® Hand Sanitizer Foam uses unique nano antimicrobial technology that not only kills on contact, but also has persistent activity that helps prevent infections. The persistence of myshield® Hand Sanitizer  Foam has been shown to remain effective for up to 4 hours.

Kills 99.999% of harmful germs – my-shield® Hand Sanitizer Foam kills 99.999% of the harmful germs it comes in contact with by disrupting the outer cell membranes resulting in a physical kill. This physical kill ensures microorganisms don’t adapt or become resistant over time.

 Alcohol-Free Formula – Most hand sanitizers contain high percentages of alcohol to poison germs, generally over 65%. This creates a highly flammable, poisonous mix that carries with it opportunity for being ingested amongst other factors. Constant use of alcohol based hand sanitizers also has the effect of drying out your skin, leading to irritation and cracking. my-shield® Hand Sanitizer Foam is water based and contains no alcohol. It’s also nonflammable, and non-poisonous, making it more effective & safer hand sanitizer for the whole family.

Moisturizes your hands with Aloe vera – my-shield® Hand Sanitizer Foam is a water-based sanitizer with added aloe vera to leave your hands feeling fresh and soft. It’s been designed to be nonirritating, leaving a fresh citronella fragrance once applied.


Annie Pryor, scientist and stay-at-home Mom, authors the website “stopthestomachflu.com“. With a Ph.D. in biochemistry, Dr. Pryor (a.k.a. Dr. Annie) has tested hand sanitizers, cleaning products and essential oils, to name a few.  We were particularly pleased with her test results of BioProtect Hand Sanitizer. You can find her entire experiment at the button below. (NOTE: Test was made on “GFS Bio-Protect” – name has been changed to “my-shield” but it is still the same product.)

We offer this forum to her and her valuable studies as a service to the lay public as her studies are all designed from the viewpoint of a concerned parent. Her focus has been in stopping the Stomach Flu caused by the Noro Virus. This virus is notoriously difficult to study which makes it difficult to determine when it is being effectively controlled. She lists the most effective Hand Sanitizers, their limitations and of course, her favorites for her family.
