Process for making a particulate laundry detergent composition

Abstract

A process for making a particulate laundry detergent composition, the process includes the steps: (a) contacting water, starch, acid and perfume to form a concentrated aqueous acidic mixture, the concentrated acidic mixture includes: (i) from about 20 wt % to about 60 wt % starch; (ii) from about 10 wt % to about 50 wt % acid; (ii) from about 2 wt % to about 20 wt % perfume; (iv) from 10 wt % to less than about 45 wt % water; the concentrated acidic mixture has a pH of less than about 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, the base detergent particles include from about 4 wt % to about 60 wt % detersive surfactant.
