摘要

The present invention relates to a solid free-flowing particulate laundry detergent composition comprising: (a) from 0.1 wt % to 15 wt % polymer particle comprising: (i) from 70 wt % to 90 wt % 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), 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 10 wt % to 30 wt % salt, wherein the salt is selected from sulphate salt and/or carbonate salt; and (b) from 0.5 wt % to 20 wt % AES particle comprising: (i) from 40 wt % to 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 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 40 wt % to 50 wt % is unethoxylated, having a degree of ethoxylation of 0; (i.ii) from 20 wt % to 30 wt % has a degree of ethoxylation of 1; (i.iii) from 20 wt % to 40 wt % has a degree of ethoxylation of 2 or greater; (ii) from 20 wt % to 50 wt % salt, wherein the salt is selected from sulphate salt and/or carbonate salt; and (iii) from 10 wt % to 30 wt % silica.
