ABSTRACT:
This invention relates to cleaning compositions for cleaning printing inks from printing rollers, blankets, machinery and the like. More particularly, this invention relates to cleaning compositions that combine inter alia., good solvency power in printing inks along with low volatility of potentially hazardous organic compounds. The cleaning composition contains a mixture of a base solvent from about 20 to 95 weight percent of tall oil fatty acid ester combined with organic solvents and/or surfactant. Water may be added to the composition for removal or rinsing since the cleaning composition contains a water-active surfactant.
