R 2 must be an alkyl group having 1 to 2 carbon atoms. That is,
This is because R 1 has an alkyl group having 4 or more carbon atoms and R 2 has an alkyl group having 3 or more carbon atoms, whereby a desired cleaning performance cannot be obtained in the obtained detergent composition. Further, among the glycol ether solvents represented by the general formula (1), other than diethylene glycol ethers, for example, monoethylene glycol, triethylene glycol, monopropylene glycol other than dipropylene glycol ethers, and tripropylene glycol Propylene glycol still cannot achieve the desired cleaning performance.
