Can dettol causes skin or blood cancer?

I'm not aware of any. Studies on point. The active ingredient in dettol, chloroxylenol (4-chloro, 3, 5 dimethylphenol), has been around a long time & has a broad spectrum of antimicrobial activity. Being insoluble in water, dettol is instead alcohol/pine oil based, and is used as an antiseptic and a cleaner. Dermatitis & possibly inhalation toxicity have been reported.
