    Safe and Persistent Antimicrobial Performance – D.Wagner

    While microorganisms are essential and symbiotic, bacteria, fungi and viruses can also cause disease. They can be removed mechanically, thermally, and as this article describes, chemically, with Gelest’s BIOSAFE® antimicrobial, a condensed polymeric silane quaternary ammonium salt. Independent studies show that hand sanitizer formulas containing the BIOSAFE® antimicrobial in conjunction with another quaternary ammonium compound meet and exceed U.S. Food & Drug Administration efficacy criteria for hand sanitizer antimicrobial protection.  Click here for more product information on BIOSAFE®.
