METHOD OF BETULIN NANOCAPSULES PRODUCTION Russian patent published in 2017 - IPC A61K9/51 A61K31/47 A61K47/36 A61J3/07 B82B3/00 

Abstract RU 2626508 C1

FIELD: nanotechnology.

SUBSTANCE: betulin is added to the suspension of agar-agar in petroleum ether in the presence of 0.01 g. of the surfactant E472c, wherein the core to shell weight ratio is 2:1, 1:1 or 1:3 when recalculating to dry matter, then, with stirring at 1300 rpm, ethyl acetate is added, the resulting suspension is filtered and dried at room temperature.

EFFECT: nanocapsules production process simplification and acceleration, reduction of losses during the nanocapsules production.
