The detergent containing compound I(R1 is C8-9 alkyl group, n is 6-15), compound II(R2 is C11-21 alkyl group, R3 and R4 are C1-4 alkyl group) and mineral oil was prepared. Thus, 10 parts of I(R1= C8, n=8), 20 parts of II (R2= C17, R3, R4= C1) and 70 parts of mineral oil(spgr=0.88 at 15/4 degree C, dynamic viscosity 6.86/40 degree C) were stirred to give the detergent.
