1. A solid free-flowing particulate laundry detergent composition comprising:
- (a) from about 0.5 wt % to about 20 wt % ethoxylated alkyl sulphate particle comprising;
(i) from about 40 wt % to about 60 wt % 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 about 0.8 to about 1.2, and wherein the partially ethoxylated alkyl sulphate anionic detersive surfactant has a molar ethoxylation distribution such that;
(i.i) from about 40 wt % to about 50 wt % is unethoxylated, having a degree of ethoxylation of 0;
(i.ii) from about 20 wt % to about 30 wt % has a degree of ethoxylation of 1;
(i.iii) from about 20 wt % to about 40 wt % has a degree of ethoxylation of 2 or greater;
(ii) from about 20 wt % to about 50 wt % salt, wherein the salt is selected from sulphate salt and/or carbonate salt; and
(iii) from about 10 wt % to about 30 wt % silica;
(b) from about 0.01 wt % to about 2 wt % perfume, wherein the perfume comprises at least about 60 wt % of perfume materials having a ClogP of about 3.0 or greater; and
(c) from about 0.1 wt % to about 5 wt % polymer particle comprising;
(i) from about 70 wt % to about 90 wt % co-polymer, wherein the co-polymer comprises;
(i.i) from about 50 to less than about 98 wt % structural units derived from one or more monomers comprising carboxyl groups;
(i.ii) from about 1 to less than about 49 wt % structural units derived from one or more monomers comprising sulfonate moieties; and
(i.iii) from about 1 to about 49 wt % structural units derived from one or more types of monomers selected from ether bond-containing monomers represented by formulas (I) and (II);
