Sodium hypochlorite-based compositions that are non-toxic and have antimicrobial and cleansing properties may include from about 0.025% to about 10% by weight of sodium hypochlorite. For example, the compositions may include less than 1% by weight of sodium hypochlorite (e.g., less than 0.5% by weight of sodium hypochlorite). The compositions may further include sodium laureth sulfate, cocamidopropyl betaine, cocamide MEA, disodium EDTA, and deionized water. Such compositions may be applied externally to a mammalian body through rinse-off or leave-on applications. Compositions also may be incorporated as a component of other products, such as deodorants, towelettes, or powders.
