Patent

CA 2380068

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.

L'invention concerne des compositions à base de pullulane et un système de durcissement à usage pharmaceutique, vétérinaire, alimentaire et cosmétique ou d'autres produits, notamment des films permettant d'emballer les aliments, les aspics ou les gelées, utilisés de préférence dans des préparations prédosées telles que des capsules molles ou dures. La composition renferme de préférence un tensioactif. L'utilisation d'une solution aqueuse permet d'obtenir des capsules de pullulane dures faisant intervenir un moulage par trempage classique dans les mêmes conditions que celles auxquelles sont soumises les capsules de gélatine classiques.
