Abstract

A liquid aqueous detergent composition is provided which contains a surface active portion, and a complexing agent, as well as, if desired, other components customarily included in detergent compositions, characterized in that the surface active portion mainly contains PA1 A. 30-70% of a surface active nonionic alkylene oxide adduct having the formula EQU RO(A).sub.x H where R represents a hydrocarbon group of 8-24 carbon atoms, each A represents independently an oxyalkylene group derived from an alkylene oxide with 2-4 carbon atoms, x represents an integer from 5-50, the number of from ethylene oxide derived oxyalkylene groups being at least 60% of the total number of oxyalkylene groups; and PA1 B. 30-70% of a surface active phosphoric acid ester having the common formula EQU (R'O).sub.y PO(OM).sub.3.sub.-y where R' is a straight or branched alkyl chain with 9-11 carbon atoms, y is an integer of 1 or 2 and M represents a monovalent cation.
