Abstract
The invention concerns compositions from modified starches, such as starch ethers or oxidized starch, more particularly hydroxpropylated starch (HPS) or hydroxylethylated starch (HES) for the use in pharmaceutical, veterinary, food, cosmetic or other products like films for wrapping food, aspics or jellies, preferably for predosed formulations like soft or hard capsules. The hard capsules obtained by the present invention with a conventional dipping molding process are similar to hard gelatine capsules (HGC).
