摘要:
The present invention relates to a process for making a particulate laundry detergent composition, wherein the process comprises the steps of: (a) contacting water, starch, acid and perfume to form a concentrated aqueous acidic mixture, wherein the concentrated acidic mixture comprises: (i) from 20wt% to 60wt% starch; (ii) from 10wt% to 50wt% acid; (ii) from 2wt% to 20wt% perfume; (iv) from 10wt% to less than 45wt% water; and wherein the concentrated acidic mixture has a pH of less than 4.5; (b) subjecting the concentrated acidic mixture to a perfume emulsification step to emulsify the perfume to form an emulsified perfume mixture in fluid form; and (c) spraying the emulsified perfume mixture in fluid form onto base detergent particles so that the emulsified perfume mixture at least partially coats the base detergent particles to form the particulate laundry detergent composition, wherein the base detergent particles comprise from 4wt% to 60wt% detersive surfactant.
