Zusammenfassung: | A composition contains at least two polyols, and optionally a binding material, with at least one non-hygroscopic polyol comprising more than 80 wt.%. The composition is obtained by co-spray drying or co-fluidised layer granulation. Also claimed are (1) tablets or compressed materials containing the composition; and (2) preparation of the composition by forming an aqueous solution of the polyols; and (a) spraying the solution into an air stream at 120-300 deg C, where the water evaporates; or (b) introducing into a fluidised bed in an air stream at 40-150 deg C, where the water evaporates. |
