| 摘要 |
A granular detergent component comprising a high level of surfactant, for example, cationic surfactant, and an inorganic carrier material is prepared by a process involving spraying an aqueous solution of the surfactant onto moving granules of the inorganic carrier material in the presence of a drying gas, preferably air, at a temperature within the range of from 65 to 200° C. The process is preferably carried out in a fluidised bed. Preferred inorganic carrier materials are sodium carbonate and zeolite MAP. |
