SOLID FREE-FLOWING PARTICULATE LAUNDRY DETERGENT COMPOSITION

The present invention relates to a solid free-flowing particulate laundry detergent composition comprising: (a) from 1.1wt% to 15wt% polymer particle comprising: (i) from 70wt% to 90wt% co-polymer, wherein the co-polymer comprises: (i.i) from 50 to less than 98 wt% structural units derived from one or more monomers comprising carboxyl groups; (i.ii) from 1 to less than 49 wt% structural units derived from one or more monomers comprising sulfonate moieties; and (i.iii) from 1 to 49 wt% structural units derived from one or more types of monomers selected from ether bond-containing monomers represented by formulas (I) and (II): wherein in formula (I), R 0 represents a hydrogen atom or CH 3 group, R represents a CH 2 group, CH 2 CH 2 group or single bond, X represents a number 0-5 provided X represents a number 1-5 when R is a single bond, and R 1 is a hydrogen atom or C 1 to C 20 organic group; wherein in formula (II), R 0 represents a hydrogen atom or CH 3 group, R represents a CH 2 group, CH 2 CH 2 group or single bond, X represents a number 0-5, and R 1 is a hydrogen atom or C 1 to C 20 organic group; and (ii) from 10wt% to 30wt% salt, wherein the salt is selected from sulphate salt and/or carbonate salt; and (b) from 0.5wt% to 20wt% AES particle comprising: (i) from 40wt% to 60wt% partially ethoxylated alkyl sulphate anionic detersive surfactant, wherein the partially ethoxylated alkyl sulphate anionic detersive surfactant has a molar average degree of ethoxylation of from 0.8 to 1.2, and wherein the partially ethoxylated alkyl sulphate anionic detersive surfactant has a molar ethoxylation distribution such that: (i.i) from 40wt% to 50wt% is unethoxylated, having a degree of ethoxylation of 0; (i.ii) from 20wt% to 30wt% has a degree of ethoxylation of 1; (i.iii) from 20wt% to 40wt% has a degree of ethoxylation of 2 or greater; (ii) from 20wt% to 50wt% salt, wherein the salt is selected from sulphate salt and/or carbonate salt; and (iii) from 10wt% to 30wt% silica.
