The USEPA (United States Environmental Protection Agency) requires products making fungicidal claims to demonstrate disinfectant efficacy against Trichophyton mentagrophytes, also known as “T. ment”. Trichophyton species are associated with public health related infections including ringworm and Athlete's Foot. Applied to tests as a spore, this fungi poses a formidable challenge for disinfectant products such that

disinfectant products have an EPA stated maximum allowable contact time of 10 minutes to demonstrate total kill. The product tested in this study of the DioxiGuard complex demonstrated total kill of the test microorganism at contact times of both 1 and 2 minutes.
