(57) [Summary] [Structure] (a) A glycol ether compound represented by the following general formula (1), and (b) a dibasic acid ester and γ. -A cleaning agent comprising at least one selected from butyrolactone. R 1 O- (R 2 O) n -R 3 (1) [ wherein, R 1 represents an alkyl group or a cycloalkyl group having 1 to 6 carbon atoms, R 2 is an alkylene group having 2 to 4 carbon atoms, R 3 Is hydrogen or an alkyl group or a cycloalkyl group having 1 to 6 carbon atoms, and n is an integer of 1 to 4] [Effect] The cleaning agent of the present invention has excellent detergency and substantially satisfies the flash point. Moreover, since it does not contain halogen atoms, there is no danger of depleting the ozone layer, It is extremely useful as an alternative cleaning agent for 1,1,2-trichloro-1,2,2-trifluoroethane and 1,1,1-trichloroethane. |
