Solid free-flowing particulate laundry detergent composition

A solid free-flowing particulate laundry detergent composition comprising:

• (a) from about 0.1 wt % to about 5 wt % hueing agent particle comprising:
• (i) from about 2 wt % to about 10 wt % hueing agent, wherein the hueing agent has the following structure:
• wherein:
• R1 and R2 are independently selected from the group consisting of:
• H;
• alkyl;
• alkoxy;
• alkyleneoxy;
• alkyl capped alkyleneoxy;
• urea;
• and amido;
• R3 is a substituted aryl group;
• X is a substituted group comprising sulfonamide moiety and optionally an alkyl and/or aryl moiety, and wherein the substituent group comprises at least one alkyleneoxy chain that comprises an average molar distribution of at least about four alkyleneoxy moieties;
• and
• (ii) from about 60 wt % to about 98 wt % clay;
• and
• (b) from about 35 wt % to about 80 wt % spray-dried particle comprising:
• (a) from about 8 wt % to about 24 wt % alkyl benzene sulphonate anionic detersive surfactant;
• (b) from about 5 w % to about 18 wt % silicate salt;
• (c) from 0 wt % to 10 wt % sodium carbonate;
• and
• (d) from 0 wt % to 5 wt % carboxylate polymer;
• 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):
• wherein in formula (I), R0 represents a hydrogen atom or CH3 group, R represents a CH2 group, CH2CH2 group or single bond, X represents a number 0-5 provided X represents a number 1-5 when R is a single bond, and R1 is a hydrogen atom or C1 to C20 organic group;
• wherein in formula (II), R0 represents a hydrogen atom or CH3 group, R represents a CH2 group, CH2CH2 group or single bond, X represents a number 0-5, and R1 is a hydrogen atom or C1 to C20 organic group;
• and
• (ii) from about 10 wt % to about 30 wt % salt, wherein the salt is selected from sulphate salt and/or carbonate salt.
