What is Zetrisil?

Zetrisil® is a proprietary nano-based silicone compound that is used solely or in conjunction with either isopropyl alcohol or conventional quaternary ammonium compounds. Zetrisil® effectively protects and/or “shields” the area any My-shield® product is applied to from microbial contamination by way of a long-lasting, cationic-charged, anti-microbial nano-silicone coating.

How does Zetrisil® work?

The Zetrisil-based formulations are effective as a bacteriostatic agent to instantly complete 99.9999% broad spectrum kill against bacteria and viruses, with the additional benefit of a residual persistent kill of up to 28 days per application.

How is the efficacy of the products measured?

The analysis technique for determining the surface charge of nanoparticles in a solution (colloids) is called “Zeta Potential”. Nanoparticles have a surface charge measured in millivolts that attracts a thin layer of ions of opposite charge to the nanoparticle surface.

Why is Zeta Potential important for Disinfectants & Sanitizers?

The greater the positive charge disinfectants or sanitizing solutions have, the greater killing effect against negatively charged bacteria and viruses, by way of opposite pole magnetic attraction.

How does Zeta Potential improve the efficacy of Disinfectants & Sanitizers?

The majority of bacteria and viruses are negatively charged nano particles. With a positively charged disinfectant and/or sanitizer they will be attracted to each other and agglomerate the negatively-charged bacteria or virus particles around the positively-charged disinfectant or sanitizer solution therefore improving the kill time and efficacy rate per volume of liquid, disinfectant or sanitizing solution.

Can Zeta potential kill bacteria and viruses magnetically?

Yes. By way of changing the magnetic charge around the bacteria or virus cell, it can damage the cell wall membrane causing a osmotic imbalance to the bacteria or virus.  This ionic, non-chemical process leads to a rupture in the cell wall, facilitates lysis and leads to the cell wall bursting.  The end result is a dead microbe and that is the power of Zetrisil®

Zeta Potential Assessment

An aliquot of 10 mL was taken from each sample and placed in the zeta check cylinder. Each measurement was completed in 30 seconds. Analysis was performed in duplicate. Results are summarized in Table 1. It was found that both the samples showed incipient stability.
