Abstract
The invention concerns compositions based on pullulan and a setting system 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 composition preferably further contains a surfactant. By using aqueous solution of the inventive compositions, the hard pullulan capsules are produced by a conventional dipping moulding process under the same process condition range than conventional gelatine capsules.
