Gelest, Inc., a leading innovator in materials science, announced today its new BIOSAFE® HE4005 and HE4001 Antimicrobial products have been approved for use as antimicrobial preservatives under U.S. EPA and FDA regulations to preserve articles including those in direct contact with finished food. BIOSAFE HE4005 and HE4001 are the only registered silane quaternary ammonium salt (silane quat) antimicrobials manufactured using a methanol-free process.
Like traditional quaternary ammonium salts (quats), silane quats are effective against an extensive variety of microorganisms by physically rupturing the microbe’s cell membrane and destroying the microbes on contact. Unlike traditional quats, silane quats can bind to a wide range of surfaces and therefore provide long-lasting protection against microorganism colonization.
