It is used in lacquer thinners, dopes, wood stains, wood preservatives and printing pastes; in coating compositions for paper and textiles; permanent markers;[4] in making artificial silk and leather; in imitation gold leaf; in celluloid cements; as a preservative for animal tissue; in metal cleaning compounds; in the manufacture of photographic film; and in hydraulic brake fluids, where it is usually mixed with an equal volume of castor oil.
