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.

Process for making a particulate laundry detergent composition

A process for manufacturing effervescence component comprises grinding a coarse acid source to obtain an acid source whereof at least 75% has a particle size from 0.1 to 150 microns, mixing the ground acid source and the carbon dioxide source and optionally the binder and/or other actives to form a mixture, and submitting the mixture to a granulation step, preferably comprising a compaction step and/or an agglomeration step.

Process for manufacturing effervescence components

The solid component comprises a finely divided component, preferably a sensitiser, and a specific polymeric component, whereby the solid component has a tressed Heubach Index of less than 1000. The solid component is preferably present in the detergent composition, preferably in a granular composition, a tablet or bar.
