Polychlorinated phenoxyphenols

General structure of PCPP

The polychlorinated phenoxyphenols (PCPP) are a group of organic poly halogenated compounds. These include triclosan [5-chloro-2- (2,4-dichlorophenoxy) phenol] and predioxin [2,3,4-trichloro-6- (2,4-dichlorophenoxy) phenol].

Triclosan can contain traces of dioxins and furans , but predioxin is broken down into dioxins.

It is noteworthy that the dioxins, which result from aqueous photolysis of Triclosan, were classified as non- toxic .
