====Current uses====

=====Industrial=====
Wood-tar creosote is to some extent used for [[wood preservation]], but it is generally mixed with coal-tar creosote, since the former is not as effective. Commercially available preparations of "[[liquid smoke]]", marketed to add a smoked flavour to meat and aid as a preservative, consist primarily of creosote and other constituents of smoke.<ref name=chenoweth206/> Creosote is the ingredient that gives liquid smoke its function; guaicol lends to the taste and the creosote oils help act as the preservative. Creosote can be destroyed by treatment with chlorine, either [[sodium hypochlorite]], or [[calcium hypochlorite]] solutions. The phenol ring is essentially opened, and the molecule is then subject to normal digestion and normal respiration.{{Citation needed|date=August 2019}}
