Independent test proves superiority of novel HyperDRYMist® automated
room disinfection technology against antibiotic-resistant S. aureus
An Independent Comparison test has demonstrated the superiority
of the novel HyperDRYMist® disinfectant technology against the
antibiotic-resistant bacterium Staphylococcus aureus (S. aureus), a
major pathogen that is notoriously tough to eliminate.
The test was carried out to demonstrate the effectiveness of the
patented, non-toxic 99S formulation compared with other solutions
whose efficacy is purely based on hydrogen peroxide at medium or low
concentration levels.
The 99S Disinfectant Solution contains a low concentration of hydrogen
peroxide (6.6%) and other carefully selected co-formulants which
boost its overall stability and biocidal activity. The unique technology
combines rapid, high-level disinfection with low amounts of disinfectant
solution, making it an efficient and effective solution for large-scale
disinfection needs.
The independent test was performed by accredited laboratory
Complife Italia following the EN 13697 standard method. Five hydrogen
peroxide-based alternatives were pitted against the solution, and the
99S disinfectant solution was shown to be the most effective against
S. aureus.
S. aureus is considered the most challenging microorganism for
disinfectants based on hydrogen peroxide due to its complex antioxidant
defence mechanism that includes catalase, an important enzyme for
bacteria that protects them from hydrogen peroxide.
All the five samples provided were tested simultaneously under the
same conditions: undiluted product, 5 minutes contact time, and clean
condition (0,3 g/l BSA). A > 5 Log reduction on the target microorganism
was required to pass the test.
During the test, the 99S formulation demonstrated its effectiveness by
achieving a 99.999% log reduction (6 log reduction) on S. aureus, while
the other products only achieved
