Patent

CA 2459593

One object of the invention is a spray-dried composition comprising an active ingredient dispersed in a carrier comprising a combination of a wall-forming carbohydrate material with from 1 to 30% by weight of agar agar relative to the dried weight of the composition. The composition of the invention presents an advantageous behavior in an aqueous or highly moist environment wherein the mobility of the active agent is restricted in the gelled carrier, thus preventing the release of the agent unless shear of heat are applied. Another object of the invention is a process for the preparation of the spray-dried composition.

Cette invention se rapporte à une composition séchée par pulvérisation qui comprend un ingrédient actif dispersé dans un véhicule contenant un matériau à base d'hydrate de carbone formant paroi associé à 1 à 30 % en poids d'agar par rapport au poids séché de la composition. Cette composition présente un comportement avantageux dans un milieu aqueux ou hautement humide où la mobilité de l'agent actif est limitée dans le véhicule gélifié, empêchant ainsi la libération de l'agent jusqu'à l'application d'un cisaillement thermique. Cette invention concerne également un procédé de préparation de cette composition séchée par pulvérisation.
