Our advanced drug carrier technology results in higher efficacy with smaller amounts of quaternary ammonium compounds (quats). For example, GermStopSQ contains 6 times less quats then our closest competitor, which is a residual sanitizer (i.e., lower efficacy), not a residual disinfectant.

An independent toxicologist compared the safety of GermStopSQ to other hare surface disinfectants. As an example, the U.S. EPA requires warnings on hard surface disinfectant products based on oral toxicity, these range from Category I (highly toxic) to Category IV (relatively non-toxic). Based on the EPA criteria and on the results of the oral toxicity study, GermStopSQ would be classified as Category IV (relatively non-toxic). For comparison, concentrated bleach solutions are classified as Category I and other quats would be classified as Category III. The toxicity study results from GermStopSQ indicate that it is less toxic than many other hard surface disinfectants.

For reasons such as these, Health Canada provided approval for GermStopSQ in all use areas, including domestic (i.e., residential homes).
