A mixed solvent composition of trichloro-1,2,2-trifluoropropane (hereinafter referred to as R113) and alcohol is widely used. Furthermore, RII3 does not attack base materials such as metals, plastics, and elastomers, and has the characteristic of selectively dissolving various types of dirt. It was perfect for.

が活発に行なわれている。[Problems to be solved by the invention] Although R113, which has been used in the past, has various advantages, it is particularly chemically stable, has a long life in the troposphere, and does not expand to reach the stratosphere. The use of chlorine radicals, which are decomposed by sunlight and generated here, causes a chain reaction with ozone and destroys the ozone layer, so the use of chlorine radicals has been regulated. For this reason, the conventional R1
In place of No. 13, the search for alternative solvents that are less likely to deplete the ozone layer is being actively conducted.
