Abstract: front page image
(DE)Vorgeschlagen werden Mikrokapseln mit mittleren Durchmessern im Bereich von 0,1 bis 5 mm, bestehend aus einer Hüllmembran und einer mindestens einen Wirkstoff enthaltenden Matrix, dadurch erhältlich, dass man (a) aus Gelbildnern, Chitosanen und Wirkstoffen eine Matrix zubereitet und (b) diese in wässrige Lösungen anionischer Polymere eintropft.
(EN)The invention relates to microcapsules with an average diameter in the range of 0.1 to 5 mm that consist of an envelope membrane and at least one matrix that contains an active substance. The inventive microcapsules are obtained by (a) preparing a matrix on the basis of gelling agents, chitosanes and active substances, (b) adding said matrix drop-wise to aqueous solutions of anionic polymers.
(FR)La présente invention concerne des microcapsules présentant des diamètres moyens compris entre 0,1 et 5 mm et consistant en une membrane enveloppe et en une matrice contenant au moins une substance active. Les microcapsules selon cette invention sont obtenues par (a) préparation d'une matrice à base de gélifiants, de chitosanes et de substances actives, puis (b) introduction goutte à goutte de ladite matrice dans des solutions aqueuses de polymères anioniques
