Process for making a granular detergent composition containing a selected crystalline calcium carbonate builder |
摘要 |
A process for preparing a detergent composition is provided. The process involves: (a) continuously mixing a detergent surfactant paste and dry starting detergent material into a high speed mixer/densifier to obtain detergent agglomerates, wherein the ratio of the surfactant paste to the dry detergent material is from about 1:10 to about 10:1; and (b) mixing the detergent agglomerates in a moderate speed mixer/densifier to further densify and agglomerate the detergent agglomerates. The dry detergent material contains a builder which is a selected crystalline calcium carbonate material substantially having a rhombohedral crystalline structure with {1,0,-1,1} crystallographic indices.
