List of Organisms Against which Dilute Hydrogen Peroxide (DHP) Technology is Reported to be Effective:

Exclusion of an organism from this list does not imply inefficacy.  As we continue microbial testing, new results will be posted.  Please contact us with questions regarding specific microbes or testing.

Additional Notes

In controlled, accredited lab testing DHP technology has demonstrated the ability to reduce 99.8% of H1N1 in one hour (sample size 1,120,000 viruses per square inch); 95.15% of MRSA in six hours (with soil load, sample size 100,000 bacteria per square inch, 99.53% without soil load); and 51% of C-Diff in 72 hours (sample size 3,780,000 bacteria per square inch, with soil load). 

In a specific maritime environment test, a client specifically asked for sampling to determine whether or not Salmonella and Listeria were present after testing, neither organism was detected.

DHP Technology has also been effective against a variety of fungi in multiple contaminated environments not identified by species.

Dry Hydrogen Peroxide (DHP) is  generally effective against any organism that is susceptible to other forms of Hydrogen Peroxide.  Although the Synexis Biodefense System has been effective against every species of dry microbe on which it has been tested, Synexis LLC makes no claim of total disinfection or decontamination of all forms of bacteria, viruses, fungi, mold, and new resistant strains. Synexis LLC is continuously testing our systems against a wide spectrum of microbial threats. Please view our data sheets in the Resources section for current test results of the Synexis Biodefense Systems.  Exclusion of an organism from our test data does not imply inefficacy.  As we continue microbial testing, new results will be posted. If your organization is interested in performing tests against a specific microbe or environmental condition, please contact us.
