The present invention provides a detergent composition for clothing containing components (a) and (b): (a) glyceryl or polyglyceryl monoether represented by formula (I); and (b) a sulfate selected from those represented by formulae (II), (III), and (IV). Component (a) contains compounds having different condensation degrees of glycerol n's, with the proviso that when component (b) is a sulfate represented by formula (II) or (III), component (a) has a condensation degree of glycerol n of 3 to 5. Formula (I) is R&#x2014;O&#x2014;(CHO)&#x2014;H (I), wherein R represents a hydrocarbon group having 6 to 22 carbon atoms; and n represents a condensation degree of glycerol and is an integer. Formulas (II)-(IV) are: R&#x2014;O&#x2014;SOM (II); R&#x2014;O-(EO)-(AO)&#x2014;SOM (III); and R&#x2014;O-(AO)-(AO)&#x2014;SOM (IV). In formulas (II-(IV), Rrepresents a hydrocarbon group having 6 to 22 carbon atoms; EO represents an oxyethylene group; AO represents an oxyalkylene group, at least one of a plurality of AOs being an oxyethylene, oxypropylene, or oxybutylene group; m represents an integer of 1 to 10; l represents an integer of 0 to 10; AO represents an oxypropylene group and/or an oxybutylene group; p represents an integer of 1 to 5; q represents an integer of 0 to 10; and M represents an alkali metal, alkaline earth metal, NH, or alkanolammonium group having 2 to 3 carbon atoms.
