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% hueing agent particle comprising: (i) from 2wt% to 10wt% hueing agent, wherein the hueing agent has the following structure:
wherein the index values x and y are independently selected from 1 to 10; and
(ii) from 60wt% to 98wt% clay; 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.
