ABSTRACT:
A process is described for the preparation of granulates that contain liposoluble and hydrophobic substances, preferably steroidal substances, and that exhibit rapid and excellent water-dispersibility. The process comprises:a) the dispersion of substance (A) in water in the presence of a surfactant (B),b) the incorporation of a water-soluble polyhydroxylated solid excipient (C) in the aqueous dispersion until a granulable pasty mass is obtained andc) the granulation of the mass.The granulates so obtained are suitable for the preparation, at the time of use, of stable and homogeneous aqueous suspensions that are used for nutritional, cosmetic or, preferably, pharmaceutical purposes.
