Abstract (en)
[origin: WO0031234A1] The present invention relates to a process for forming an agglomerated particle containing the steps of providing at least one alkaline material, a core material, and at least one acid active. The alkaline material and the core material are added to a mixer and agglomerated therein, to form an agglomerated particle comprising an interior and an exterior. The acid active is then added to the mixer. The core material is concentrated into the interior of the agglomerated particle by adding substantially all of the core material to the alkaline material before more than about 50% of the acid active is added to the mixer.
