PURPOSE:To obtain the subject compsn. which has a strong detergency and is exclusively used for immersion washing by mixing a specific cationic surfactant, a nonionic surfactant, a semipolar surfactant, and a glycol ether solvent in a specified wt. ratio. CONSTITUTION:This detergent compsn. is prepd. by mixing 1-5wt.%. cationic surfactant of formula I (wherein R<1> and R<2> are each 12-24C alkyl or alkenyl; R<3> and R<4> are each methyl, ethyl, etc.; and X is halogen, CH3SO4, etc.) having an iodine value of 40-100 (e.g. dioleyldimethylammonium chloride), 10-30wt.%. nonionic surfactant of formula II (wherein R<5> is 10-20C alkyl, alkenyl, etc.; and (n) is 5-15) (e.g. a polyoxyethylene mixed-alkyl ether), 0.5-8wt.%. semipolar surfactant of formula III (wherein R<6> is 10-22C alkyl; and R<7> and R<8> are each methyl, ethyl, etc.), and 1-70wt.%. glycol ether solvent of formula IV (wherein R<9> is 1-4C alkyl; R<10> is 1-2C alkylene; and R<11> and R<12> are each H or methyl). |
