Abstract:
A detergent which comprises:(A) 50 vol % or more of a polar organic solvent having low compatibility with water; wherein the polar organic solvent having low compatibility with water is at least one compound selected from the group consisting of a propylene glycol alkyl ether compound represented by the following formula II: wherein R3 and R4 are each independently a hydrogen atom or alkyl group having 1 to 4 carbon atoms, and p and q are each independently a number from 0 to 3, with the proviso that p+q=1 to 3, R3 and R4 cannot be a hydrogen atom at the same time, when one of R3 and R4 is a hydrogen atom, the other is an alkyl group having 3 or more carbon atoms, and when R3 and R4 are both a methyl group or ethyl group, p+q=2 to 3,(B) 10 vol % or more of an imidazolidinone compound represented by the following formula (I): wherein R1 and R2 are each independently a methyl group or ethyl group; and(C) 21 vol % or more of water the above vol % being based on the total volume of the polar organic solvent, the imidazolidinone and the water, and which forms a homogeneous phase and is used at a temperature of 40Â° C. to 70Â° C.
