coal-tar
Black industrial residue
Coal-tar is a thick, dark liquid produced when coal is heated in the absence of air—a byproduct of making coke for steel production.
It contains hundreds of organic compounds and serves as a source for dyes, drugs, and industrial chemicals.
Coal-tar derivatives appear in medicated shampoos and ointments for treating dandruff and psoriasis.
