摘要 |
The degreasing composition comprises a surfactant composition comprising a compound (a) represented by the general formula (1): R1O(AO)nH (1) wherein R1 is a substituted or unsubstituted hydrocarbon group having 6 or more carbon atoms; A is at least one group selected from the group consisting of an ethylene group, a propylene group, a butylene group and a styrene group, provided that an ethylene group in A is 5 mol or more per 1 mol of R1, and that the ethylene group is 50 mol % or more per 100 mol % of said A; and n is an integer of 5-50; a compound (b1) represented by the general formula (2): <IMAGE> (2) wherein R2is a substituted or unsubstituted hydrocarbon group having 6 or more carbon atoms, E is an ethylene group, and n is an integer of 1-20; and a compound (b2) represented by the general formula (3): <IMAGE> (3) wherein R2, E and n are the same as in the formula (2); a weight ratio of compound (a)/(compound (b1)+compound (b2)) being 10/90-95/5, and a weight ratio of compound (b2)/compound (b1) being 20/80 or more, and further comprising an alkali builder in a weight ratio [(compound (a)+compound (b1)+compound (b2))/alkali builder] of 1:0.1-1:2,000.
