ABSTRACT:
Process for improving the dispersibility and the filterability of scleroglucan powders, in which a surfactant is incorporated in the coagulated polymer. The powder obtained according to the process has a dispersibility and a filterability after drying of the coagulum which are greatly superior to those of a powder treated after drying with the same quantity of surfactant or of a powder in solution treated with this same quantity of surfactant.
