Abstract
A process for preparation of a granular detergent composition which process comprises the steps of PA1 (i) forming a liquid feedstock comprising a liquid binder and a structurant; PA1 (ii) dosing the liquid feedstock and a solid component into a high-speed mixer/densifier, to form a granular detergent material and forming or introducing further structurant in the high-speed mixer/densifier; PA1 (iii) subsequently treating the granular detergent material in a moderate-speed granulator/densifier, whereby it is brought into or maintained in a deformable state; and PA1 (iv) drying and/or cooling the product of step (iii).
