Processes for making a granular detergent composition containing a crystalline builder |
摘要 |
A process for preparing high density detergent compositions is provided. The process comprises the steps of: (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; (b) mixing the detergent agglomerates in a moderate speed mixer/densifier to further densify and agglomerate the detergent agglomerates; and (c) drying said detergent agglomerates so as to form the high density detergent composition. The dry detergent material may contain a builder material including a crystalline microstructure in which a carbonate anion, a calcium cation and at least one water-soluble cation are contained. The process may include one or more additional processing steps such as adding a coating agent such as the builder material described herein after the moderate speed mixer/densifier to facilitate and control agglomeration.
