PURPOSE:To obtain a detergent for degreasing which is excellent in qualities and replaces the conventional fluorocarbon and chlorine-base solvents by compounding specified alcohols and fatty acid esters. CONSTITUTION:A detergent for degreasing comprising 3 to 4C alcohols and fatty acid esters. The detergent has good degreasing performance and finish comparable with those of the conventional fluorocarbon and chlorine-base solvents and does not destruct ozone. Further, the conventional apparatus for cleaning can be used substantially as they are, since the detergent can readily be recovered by boiling or distillation by the use of a washing machine and a distiller which have been used for the recovery of the conventional fluorocarbon and chlorine-base solvents. In addition, water rinse for removing the detergent from the washed article is not necessary in working steps, since it has a low boiling point and thus the washed article is ready to dry. Accordingly, there is no possibility of polluting water environment with waste water. |
