PROBLEM TO BE SOLVED: To provide a detergent composition for a body and hair such as a body soap, hand soap, facial wash and hair shampoo having excellent time stability and high viscosity retention in temperature change, independent of temperature of using environment and giving no slimy feeling in use. SOLUTION: The detergent composition comprises (a) 1-5 mass% of a fatty acid alkyleneoxide derivative expressed by formula (1): R<SP>1</SP>O(EO)x(BO)y(EO)zH (wherein, R<SP>1</SP>is 8-14C alkyl or the like, EO is oxyethylene, BO is oxybutylene, 1≤y≤3, and 0≤x+z≤3), (b) 0.5-3 mass% of a polyoxyalkylene polyol isostearic acid ester expressed by formula (2): Z-(O[(EO)m(AO)n]-R<SP>2</SP>)a (wherein, Z is a residue without a hydroxyl group comprising a sugar skeleton having a ring acetal structure having 6-18C and 3-12 hydroxyl groups, 3≤a≤12, EO is oxyethylene, AO is 3-4C oxyalkylene, R<SP>2</SP>is an isostearic acid residue or hydrogen, esterification ratio is 35-100%, 12≤m+n≤70, m/(m+n)≥0.8), (c) 1-10 mass% of a taurine derivative expressed by formula (3): R<SP>3</SP>CONR<SP>4</SP>C<SB>2</SB>H<SB>4</SB>SO<SB>3</SB>M (wherein, R<SP>3</SP>CO is 6-10C acyl, R<SP>4</SP>is hydrogen or 1-3C alkyl and M is hydrogen or the like), and (d) at least one kind of amphoteric surfactants selected from the group consisting of alkylbetaine-type amphoteric surfactants and alkylamidobetaine-type amphoteric surfactants; wherein a+b+c+d is 10-30 mass%, mass ratio of a/b is 1/1 to 4/1, mass ratio of c/d is 1/3 to 3/1, and mass ratio of c to the total components c/(a+b+c+d) is >0.2.
