Polychloro phenoxy phenols (polychlorinated phenoxy phenols, PCPPs) are a group of organic polyhalogenated compounds. Among them include triclosan and predioxin which can degrade to produce certains types of dioxins and furans.{{cite journal |vauthors=Rule KL, Ebbett VR, Vikesland PJ |title=Formation of chloroform and chlorinated organics by free-chlorine-mediated oxidation of triclosan |journal=Environ.
