A laundry washing composition comprises: (a) anionic surfactant comprising at least one surfactant compound of formula (I): <paragraph lvl="0"><in-line-formula>R1-Z-M+ (I) </in-line-formula> wherein R1 is a branched alkyl or branched alkenyl group; Z- is a hydrophobic anion; and M+ is a counter cation, preferably an alkali metal ion such as sodium; (b) a detergency enhancing polymer which is a homopolymer or copolymer containing one or more monomer units independently selected from those of formula (II) wherein -A- is selected from groups of formula -R5-, -R5-(CO)-R6-, -R5-(CO)-O-R6, -R5-O-(CO)-R6-, -R5-(CO)-NH-R6-, -R5-NH-(CO)-R6-, wherein R5 and R6 are independently absent, or represent C1-3 alkyl groups; R1, R2 and R3 are independently selected from hydrogen, C1-3 alkyl, C1-3 alkenyl, hydroxy-C1-3 alkyl and C5-8 cycloalkyl groups; and R4 is selected from groups as defined for A above; wherein R3 may also represent a bridge, group with the group R4, said bridging group being selected from groups as defined for A above; and X- is a monovalent anion or an n'th part of an n-valent anion; and (c) optionally, one or more other ingredients; wherein, when the composition comprises sodium tripolyphosphate builder, the composition is particulate and has a bulk density of at least 650 g/liter and when the composition comprises zeolite builder, the amount of zeolite builder is no more than 19% by weight of the composition.
