An aqueous detergent liquid composition comprising: (i) a surfactant system comprising anionic surfactant, (ii) optionally, 0.01 wt% or more suspended particles, (iii) 0.5 wt% or more polymer that reduces the composition viscosity at 20 s-1, and (iv) at least 0.05 wt% of a suspending system comprising copolymer formed by addition polymerisation in the presence of: (A) 0.1 to 5 wt% of a first monomer consisting of an ethylenically unsaturated diacid of formula (I): HOOC-CR1=CR2-COOH or an unsaturated cyclic anhydride precursor of such an ethylenically unsaturated diacid, the anhydride having formula (II), where R1 and R2 are individually selected from H, C1-C3 alkyl, phenyl, chlorine and bromine; (B) 15 to 60 wt% of a second ethylenically unsaturated monoacidic monomer consisting of (meth)acrylic acid; (C) 30 to 70 wt% of a third ethylenically unsaturated monomer consisting of ehtyl ester of (meth)acrylic acid; (D) 1 to 25 wt% of a fourth ethylenically unsaturated monomer, consisting of surfmer of formula (III), wherein each R3 and R4 are each independently selected from H, methyl, -C(=O)OH, or –C(=O)OR5; R5 is a C1-C30 alkyl; T is -CH2C(=O)O-, -C(=O)O-, -O-, -CH2O-, -NHC(=O)NH-, -C(=O)NH-, -Ar-(CE2)z-NHC(=O)O-, -Ar-(CE2)z-NHC(=O)NH-, or -CH2CH2NHC(=O)-; Ar is divalent aryl; E is H or methyl; z is 0 or 1; k is an integer in the range of 0 to 30; and m is 0 or 1; with the proviso that when k is 0, m is 0, and when k is in the range of 1 to 30; m is 1; (R6O)n is polyoxyalkylene, which is a homopolymer, a random copolymer, or a block copolymer of C2-C4-oxyalkylene units, wherein R6 is C2H4, C3H6, C4H8, or a mixture thereof, and n is an integer in the range of 5 to 250; Y is -R6O-, -R6H-, -C(=O)-, -C(=O)NH-, =R6NHC(=O)NH-, or -C(=O)NHC(=O)-; and R7 is substituted or unsubstituted alkyl selected from the group consisting of C8-C40 linear alkyl, C8-C40 branched alkyl, C8-C40 carbocyclic alkyl, C2-C40 alkyl-substituted, phenyl, aryl-substituted C2-C40 alkyl, and C8-C80 ...
