Abstract (en)
The present invention relates to a solid free flowing particulate laundry detergent composition comprising: (a) anionic detersive surfactant; (b) from 0wt% to 8wt% zeolite builder; (c) from 0wt% to 4wt% phosphate builder; (d) from 0wt% to 8wt% sodium carbonate; (e) from 0wt% to 8wt% sodium silicate; (f) from 4wt% to 20wt% organic acid; and (g) polyester soil release polymer, wherein the polyester soil release polymer has the structure: wherein n is from 1 to 10; m is from 1 to 15 ; X is H or SO 3 Me; wherein Me is H, Na + , Li + , K + , Mg 2+ , Ca 2+ , Al 3+ , ammonium, mono-, di-, tri-, or tetra-alkylammonium; wherein the alkyl groups are C 1 -C 18 alkyl or C 2 -C 10 hydroxyalkyl, or any mixture thereof; R1 are independently selected from H or C 1 -C 18 n- or iso-alkyl; and/or the polyester soil release polymer consists of structure units (1) to (3): wherein: a, b and c are from 1 to 10; x, y is from 1 to 10; z is from 0.1 to 10; Me is H, Na + , Li + , K + , M 2+ , Ca 2+ , Al 3+ , ammonium, mono-, di-, tri-, or tetra-alkylammonium wherein the alkyl groups are C 1 -C 18 alkyl or C 2 -C 10 hydroxyalkyl, or any mixture thereof; R 1 , are independently selected from H or C 1 -C 18 n- or iso-alkyl; R 2 is a linear or branched C 1 -C 18 alkyl, or a linear or branched C 2 -C 30 alkenyl, or a cycloalkyl group with 5 to 9 carbon atoms, or a C 6 -C 30 aryl group, or a C 6 -C 30 arylalkyl group, wherein the composition at 1wt% dilution in deionized water at 20°C, has an equilibrium pH in the range of from 6.5 to 9.0, wherein the composition comprises from 30wt% to 90wt% base detergent particle, wherein the base detergent particle comprising (by weight of the base detergent particle): (a) from 4wt% to 35wt% anionic detersive surfactant; (b) optionally, from 1wt% to 8wt% zeolite builder; (c) from 0wt% to 4wt% phosphate builder; (d) from 0wt% to 8wt% sodium carbonate; (e) from 0wt% to 8wt% sodium silicate; (f) from 1wt% to 10wt% organic acid; and (g) optionally, from 1wt% to 10wt% magnesium sulphate.
