Abstract: The present invention relates to a method for making a laundry detergent particle comprising from 10 to 60 wt % (anhydrous basis) zeolite, from 12 to 75 wt % polycarboxylate polymer, and optional additional ingredients to 100% by weight, said method comprising preparing an aqueous slurry comprising zeolite, and polycarboxylate polymer and optional additional ingredients and spray drying the slurry. The weight ratio of zeolite (anhydrous basis) to polycarboxylate polymer in the slurry is from 4:1 to 1:2. The particles have been found to reduce caking of detergent product whilst providing improved cleaning compared with the addition of the polycarboxylate polymer as a separate granule. The invention also includes detergent compositions comprising such particles. The particles may be incorporated into a finished detergent composition as part of an agglomerate or extrudate.
