Process for the production of anionic detergent particles

Process for the production of anionic detergent particles

A non-tower process for producing detergent particles comprising more than 20% by weight of anionic surfactant, at least 15% by weight of phosphate builder and 1-40% by weight of aluminosilicate builder, the process comprising the steps of feeding the phosphate builder and a paste material comprisin...

Zusammenfassung:A non-tower process for producing detergent particles comprising more than 20% by weight of anionic surfactant, at least 15% by weight of phosphate builder and 1-40% by weight of aluminosilicate builder, the process comprising the steps of feeding the phosphate builder and a paste material comprising the anionic surfactant and water into a flash reactor comprising a drying zone, heating the material in the drying zone, the drying zone containing agitation means for agitating and transporting the material therein and the particles forming therefrom through the drying zone, wherein at least a portion of the aluminosilicate is added as a layering agent.
