VIROLYZE 60 Second Kill Time on All Bacteria and Viruses:

 

VIROLYZE has a pH of 6.5-6.8 and 500ppm of HOCL to give it a 20 second kill time.

 

Studies show that HOCL in concentrations of 50 to 500 ppm viruses shows a mortality rate of 99.999% for all viruses. By using the concentration of 500 ppm we can be confident of that kill rate with VIROLYZE that has been unsealed and set on a shelf for more than six months; up to a year unopened. 

 

“The Fundamentals of Chlorine Chemistry and Disinfection" December 2007, by George Bowman, the Wisconsin State Lab of Hygiene and Rick Mealy, Wisconsin Dept. of Natural Resources states:

 

“The measure commonly used to gauge the killing power of HOCl or any particular agent is the “CT” value.”

 

 “CT” stands for Concentration x Time with Concentration 

  being in ppm (parts per million) and Time being in

  (minutes).

 

A CT value of 10 for HOCl means:

Exposure to 10 ppm for 1.0 minute       (10 x 1 = 10 CT) 

Exposure to 1.0 ppm for 10 minutes     (1 x 10 = 10 CT) 

Exposure to 2.0 ppm for 5 minutes       (2 x 5 = 10 CT)

 

VIROLYZE Extrapolation:

Exposure to 500 ppm for 0.006 minutes (500 x0.006 = 3 CT)

 

       Conclusion: The lower the CT value, the more highly

       effective the killing agent.
