PURPOSE: A cleaning agent composition for machinery is provided to ensure excellent cleaning effect in precision machine and subsystem hard to be separated and to promote the degradation of contaminant molecules due to good penetration ability. CONSTITUTION: A cleaning agent composition for machinery comprising dichloropropane includes 1~2 weight% of 1,2-dichloropropane, 50~85 weight% of dimethylsuccinate, and 5~45 weight% of diethylene glycol monomethyl ether, and 2~8% of hydrocarbon solvent. The cleaning agent composition for machinery is prepared by reacting 1,2-dichloropropane, dimethylsuccinate, diethylene glycol monomethyl ether, and hydrocarbon solvent in an SUS reactor at 40 °C for 3 hours. |
