Abstract The invention pertains to aqeuous liquid detergent compositions on the basis of nonionic and anionic or cationic detergents and electrolytes which include a effective amount of an anionic alkylpolyalkylene oxide derivative selected from the group consisting of: (1) anionic alkylpolyalkyleneoxide derivatives having the formula: Y-(CH2)p-[o-(CH2)n]z-o-(CH2)q-X, (2) anionic di(alkylpolyalkyleneoxide) derivatives having the formula: H-(CH2)p-[0-(CH2)n]y-0 R-X, and H-(CH2)p-[0-(CH2)n]x-0 (3) anionic di(alkylpolyalkyleneoxide) derivatives having the formula: H-(CH2)p-[0-(CH2)n]y z H-(CH2)p-[0-(CH2)n]x in which X is a salt of a mono-valent oxygen-containing anionic group, Y is hydrogen or a salt of a mono-valent oxygen-containing anionic group, z is a phosphate or phosphonate salt, R is Cl-C3 alkynyl, q is 0-4, p is 0-4, z is 1-14, x is 0-14, y is 0-14 and x+y is 1-14 and n is 2-3. Inclusion of the alkylpolyalkyleneoxide derivatives results in an improvement of the long term storage stability of the detergent composition.
