(a) aus Lecithinen bzw. Phospholipiden, Wachskörpern und Wirkstoffen eine Matrix herstellt, (b) diese mit wässrigen Lösungen von Chitosanen in Kontakt bringt und dabei eine Hüllenausformt. New nanocapsules with average diameters in the range from 10 to 5000 nm are proposed, consisting of an envelope membrane and a matrix containing at least one active ingredient, which can be obtained by (a) produces a matrix from lecithins or phospholipids, wax bodies and active substances, (b) bringing them into contact with aqueous solutions of chitosans, thereby forming a shell. |
