METHOD OF ENCAPSULATION ASPIRIN IN XANTHAN GUM Russian patent published in 2015 - IPC A61K31/60 A61K9/51 A61K47/36 A61J3/07 B82B3/00

Abstract RU 2561686 C1

FIELD: nanotechnology.

SUBSTANCE: aspirin suspension is mixed with benzene and the resulting mixture is dispersed into a suspension of xanthan gum in butanol in the presence of the agent E472s while stirring of 1000 rpm/s, then chloroform is poured, the resulting suspension of nanocapsules is filtered and dried, at that the ratio of shell/core in nanocapsules is 1:5, 3:1 or 1:1.

EFFECT: acceleration and simplification of the process of production of nanocapsules with high yield by weigh.
