Abstract (en)
[origin: EP0972822A1] Surfactant granules comprise 5-80 wt.% linear alkylbenzene sulfonate (LAS) and 20-95 wt.% sodium silicate, have an average particle size of at least 50 mu m and have an ffc flowability value of at least 7 (Chem.-Ing.-Techn., 67, 60, 1995). An Independent claim is also for production of surfactant granules by mixing finely divided crystalline sodium disilicate having a particle diameter of 150 mu m or less with at least one LAS.
