Process for preparing high bulk density detergent compositions. |
摘要 |
<p>A process for preparing a granular detergent composition or component having a bulk density of at least 550 g/l, which comprises (i) feeding a liquid acid precursor of an anionic surfactant, a solid water-soluble alkaline inorganic material and optionally other materials into a high-speed mixer/densifier, the mean residence time being from about 5 to 30 seconds; (ii) subsequently treating the granular detergent material in a moderate-speed granulator/densifier, whereby it is brought into or maintained in a deformable state, the mean residence time being from about 1-10 minutes; and finally (iii) drying and/or cooling the detergent material. t</p> |
