Description

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

[Prior art] 1,1,2-1-lichloro-1,2,2-tri, which is nonflammable, non-exposing, low toxicity, and has good stability, is used as a dry cleaning solvent for fur coats, suits, etc. Fluoroethane (hereinafter referred to as R113) is widely used. In addition, R113 can provide a soft finish without damaging clothes due to its moderate dissolving power. In addition to R113, other dry cleaning solvents include Perchlor. ethylene, 1,1.1
-Trichloroethane etc. are also used.

[Problem to be solved by the invention] Although R113, which has been used in the past, has various advantages, it is a substance that is suspected of destroying ozone in stratified fields and causing skin cancer. There is something
In addition, it is necessary to reduce the amount of perchlorethylene, 1,1.1 to trichloroethane, etc., as they pose a problem of groundwater contamination. The present invention aims to solve these problems by providing a new dry cleaning detergent.

[Means for Solving the Problems] The present invention has been made to achieve the above-mentioned objects, and
The present invention provides a dry cleaning detergent containing a specific chlorofluorinated hydrocarbon having 3 carbon atoms as an active ingredient.
