Although some of the variations perform better than others, there are a number of advantages and disadvantages that they have in common. This is largely because products formulated with QACs are readily available and versatile. As the manufacturer of Nemesis eH2O, we believe it is difficult to imagine many disinfection applications in which Quats represent a better option than stabilised hypochlorous acid. There has been concern that their widespread use will lead to the development of resistant organisms, and it has been suggested that limits should be place on their use. Product Safety While the chemistry of both Purell® and LEXI® are similar, LEXI differs from Purell because LEXI, as a non-alcoholic sanitizer, fundamentally provides longer-lasting superior coverage and protection.
