Product details
Kills 99.9% of common household germs (Staphylococcus aureus, Salmonella enterica, Escherichia coli, Influenza A virus, Rhinovirus type 37, and Trichophyton interdigitale (Athlete's foot fungus)). Protects and keeps fabrics whiter longer (when compared to bleach that only contains sodium hypochlorite and water).
Regular bleach is sodium hypo. Leads me to believe there is something else in there.
