| description | Un procédé de formation et d'enrobage simultanés de petites particules d'un composé à partir d'une solution comprend: (a) la dissolution dudit composé dans un premier solvant; (b) la préparation d'une solution de matériau d'enrobage et d'un électrolyte dans un deuxième solvant miscible avec le premier solvant et dans lequel le composé à enrober est plus ou moins insoluble, en une quantité utile, mais juste insuffisante pour provoquer la coacervation du matériau d'enrobage sans interagir avec lui; (c) le mélange des solutions des étapes (a) et (b), et leur agitation pour la précipitation du composé sous forme de petites particules et la formation simultanée d'un coacervé du matériau d'enrobage; et (d) la gélatinisation du matériau d'enrobage.
Process for the formation and the simultaneous encapsulation of small particles of a compound from solution which comprises: (a) dissolving said compound in a first solvent; (b) preparing a solution of encapsulating material and an electrolyte in a second solvent which is miscible with the first solvent and in which the compound to be encapsulated is more or less insoluble, in an amount which is effective, but present in an amount just insufficient to cause coacervation of the encapsulating material without interacting with it; (c) mixing the solutions from step (a) and (b) while stirring to cause the concurrent precipitation of the compound as small particles and formation of a coacervate of the encapsulating material; and (d) gelling the encapsulating material. |
