METHOD OF PRODUCING ZINC OXIDE MICROCAPSULES Russian patent published in 2015 - IPC A61K9/50 A61K33/30 A61K47/30 A61J3/07 

FIELD: chemistry.

SUBSTANCE: invention relates to microencapsulation, particularly to a method of producing zinc oxide microcapsules. The method is characterised by that the microcapsule shell used is carrageenan, wherein a weighed portion of zinc oxide in dimethylsulphoxide is mixed with a suspension of carrageenan in butanol in the presence of an E472c surfactant; ethanol is added to the obtained suspension as a precipitant; the obtained suspension is filtered and dried at room temperature.

EFFECT: method provides a simple and faster process of producing zinc oxide microcapsules, reduces losses when producing microcapsules.
