SOLID FREE-FLOWING PARTICULATE LAUNDRY DETERGENT COMPOSITION

摘要

The present invention relates to a solid free-flowing particulate laundry detergent composition comprising: (a) from 0.1wt% to 5wt% 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): formula (I):
wherein in formula (1), 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; formula (II)
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 0.1wt% to 5wt% hueing agent particle comprising: (i) from 2wt% to 10wt% 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 four alkyleneoxy moieties; and (ii) from 60wt% to 98wt% clay.
