EFFICACY TESTS

DIFFICIL-S^® has been independently tested by NHS

The active component of DIFFICIL-S^® is chlorine dioxide, present as a disssolved gas in a solution

with outstanding wetting properties. Spore penetration is readily achieved and then the organism is

swiftly killed by the potent destructive action of chlorine dioxide on the organism's internal chemical structure.
