No. While chlorine dioxide has chlorine in its name, its chemistry is very different from the corrosive chemistry of chlorine bleach. The primary differences are that chlorine dioxide is less caustic, safer, and gentler than bleach and many other antiseptics and antimicrobials, plus it remains effective under organic load. Further, chlorine bleach produces harmful by-products to the environment, including trihalomethanes (THM) and haloacetic acids (HAAS). Vital Oxide breaks down to a simple salt, producing no harmful by-products.
