    BZK Research Evidence

    Efficacy In A School Setting

    Schools can be cramped and close-proximity environments that easily facilitate the transmission of illness. Additionally, children often don't wash their hands regularly and even alcohol based sanitizers, if used at all, have no persistent effects to help combat the transfer of germs. This clinical trial assessed the effectiveness of a hand sanitizer that has both immediate and persistent antimicrobial effects in a school setting. 

    The results of the study where as follows: "Immediate and persistent efficacy was effective in reducing illness absenteeism among both students and staff in a school setting.” Illness outbreaks, where more than 10% of students or staff were ill at the same time, was reduced by 87.5%.

    Similar to the persistent hand sanitizer used in this study, Invisi-Shield uses an effective formula with the active ingredient BZK (see below for more details) to give both immediate and persistent effects for the user.

    Efficacy In A Hospital Setting

    This purpose of this study was to evaluate the effectiveness of BZK-based hand sanitizers in combating skin contamination of healthcare workers by S. aureus. in comparison to 70% ethanol hand sanitizers. The study use 40 volunteer test subjects to participate in the ten day study. During the first week, the subjects used the 70% ethanol-based sanitizer whereas during the second week, the subjects used the BZK-based product.

    Results: "The results showed a significant reduction in total bacterial colony counts of S aureus during the week of BZK use as compared with the week of 70% ethanol sanitizer use."

    Conclusion: "There was a significant decrease in transient S. aureus on the fingertips of healthcare workers in the BZK hand sanitizer use week as compared with the 70% ethanol hand sanitizer use week."

    Efficacy Against A COVID-19 Clone Virus

    This study tested another BZK product against a virus that is structurally similar to the cause of COVID-19 called Human Coronavirus 229E. The BZK product effectiveness was tested against this viral strain by exposing it to the BZK sanitizer three separate times at 30, 60, and 120-seconds. After all three tests, 99.9% of the virus had been eliminated.

    Additional quote: "The study showed that BZK-manufactured products demonstrated "persistent antibacterial efficacy" even up to four hours after bacterial contact with skin -- far longer than the ten minutes or so or skin protection offered by alcohol-based sanitizers."

     

      Additional Evidence

      A Word From The Canadian FDA

      Conclusion: The efficacy of BZK and BZT based hand sanitizers have been confirmed through various studies where alcohol-based sanitizer was used as a control standard and they were proven to be equivalent. “…. clinically proven ingredients are just as effective as alcohol-based sanitizers and have additional benefits.”

      What's The CDC Up To?

      Conclusion: "The research for use of hand sanitizers to guide CDC Guidelines was paid for by the largest manufacturer of alcohol-based hand sanitizers—The GoJo Corporation." If there are other products like Invisi-Shield out there, why aren't they being looked at as healthy and effective alternatives that other studies have shown BK-based products to be? We suspect something fishy is going on here! Why else would the largest manufacturer of alcohol-based sanitizers partner with the CDC but to promote their own product to the masses? Quite often we here folks complaining that those alcohol-based sanitizer cause terribly dry hands; there is a better and easier way: Invisi-Shield.

       

      Description and Usages

      The active ingredient in Invisi-Shield, Benzalkonium chloride (BZK), has become a key ingredient in widespread spectrum of products due to their broad-spectrum antimicrobial properties against bacteria, fungi, and viruses. In 1947, the first BZK containing products where approved by the EPA and have since expanded to a wide array of usages. BZK can be found in cosmetics and personal hygiene products and has even become one of the most common ingredients in disinfectant products in residential, industrial, agricultural,and clinical settings. BZK is part of a chemical family called quaternary ammonium compounds (QACs). QACs contains both charged and uncharged areas, that act to destroy the cell membrane of bacteria and viruses.
