Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a detergent for dry cleaning.

[Prior art] Nonflammable, low toxicity, and stable solvent for dry cleaning of fur coats, suits, etc. 1.1.2
-Trichloro-1,2,2-trifluoroethane (hereinafter referred to as R113) is widely used. Moreover, R113 can provide a soft finish without damaging clothing due to its moderate dissolving power. This R1 is used as a dry cleaning solvent.

[Problems to be solved by the invention] Despite the fact that conventionally used R113 has various advantages, it has a long lifetime in the troposphere and diffuses into the stratosphere, where it is decomposed by sunlight and becomes chlorine. The use of R113 has been regulated because it generates radicals that cause a chain reaction with ozone and destroy the ozone layer. Perchlorethylene, 1.1.
It is necessary to reduce the amount of 1-trichloroethane and the like used because of the problem of groundwater contamination.

Therefore, an object of the present invention is to provide a new dry cleaning detergent to replace these problems in order to solve these problems.
