COMPOSITION

An aqueous detergent liquid composition comprising: (i) a surfactant system comprising anionic surfactant, and (ii) at least 0.05 wt % of a polymer formed from the polymerisation of monomers consisting of monomer (A1): R1C=CR2R3 (A1) And optionally monomer (A2): R4C=CR5R6 (A2) R1 and R2 are each independently selected from H, methyl, -C(=O)OH, or -C(=O)OR7, wherein R7 is a C1-C30 alkyl; R3 is T1-[CH2]k-[O]p-[R8O]q-Y1-R9 T1 is -CH2C(=O)O-, -C(=O)O-, -O-, -CH2O-, -NHC(=O)NH-, -C(=O)NH-, -Ar-(CE2)x-NHC(=O)O-, -Ar-(CE2)x-NHC(=O)NH-, or -CH2CH2NHC(=O)-; Ar is divalent aryl; E is H or methyl; x is 0 or 1; k is an integer in the range of 0 to 30; and p is 0 or 1; optionally with the proviso that when k is 0, p is 0, and when k is in the range of 1 to 30; p is 1; (R8O)q is polyoxyalkylene, which is a homopolymer, a random copolymer, or a block copolymer of C2-C4-oxyalkylene units, wherein R8 is C2H4, C3H6, C4H8, or a mixture thereof, and n is an integer in the range of 5 to 250; Y1 is -R8O-, -R8H-, -C(=O)-, -C(=O)NH-, =R8NHC(=O)NH-, or - C(=O)NHC(=O)-; and R9 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 complex ester; wherein the R11 alkyl group optionally comprises one or more substituents selected from the group consisting of hydroxy, alkoxy, and halogen; R4 and R5 are independently H or C1-4 alkyl, preferably H or methyl; R6 is -C(O)-OR10, where R10 is H or C1-4 alkyl, preferably H or methyl, more preferably H; and wherein the degree of polymerisation of polymer (ii) is 30 or more.
