The International Agency for Research on Cancer has classified it as possibly carcinogenic to humans. It may contain carcinogenic PAHs (Polycyclic Aromatic Hydrocarbons) as a contaminant.
A thick liquid obtained as a by-product in the destructive distillation of bituminous coal at very high temperatures. It is believed that over 10,000 different compounds make up coal tar, but only 400 have been identified. It is used as a biocide to treat various skin conditions, such as eczema, psoriasis, and dandruff. Coal tar has been found to be comedogenic and a contact allergen. Moreover, it is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans.
