PROCESS FOR MAKING COMPACT DETERGENT COMPOSITIONS |
摘要 |
A process for the continuous preparation of a granular detergent composition or component having a bulk density greater than 650 g/l which comprises the steps of: i) dispersing a detergent active paste throughout a powder stream in a high speed mixer with a residence time of from 2 seconds to 30 seconds, ii) forming an agglomerate in a moderate speed mixer/agglomerator with a residence time of less than 2 minutes, in which, optionally, a finely divided powder may be added, iii) drying and/or cooling. Granular detergent compositions which are made by this process, and which have excellent solubility properties especially with respect to dispensing and rate of dissolution are also described. |
