Assignee: RESEARCH & BUSINESS FOUNDATION SUNGKYUNKWAN UNIVERSITY
Field: Pharmaceuticals (Chemistry)
Classification: CPC B  A | IPC A  B

Claim 6:
7. A Pickering emulsion comprising:
each different liquid, a dispersed phase and a continuous phase; and
an anionic cellulose nanofibril and a cationic hectorite nanoplate particle structure that forms a coacervate interfacial film which is located at an interface of the dispersed phase and the continuous phase and lowers an interfacial tension therebetween,
wherein the cationic hectorite nanoplate particle structure contains a hectorite nanoplate particle and a cationic surfactant coupled to a surface of the hectorite nanoplate particle,
wherein the anionic cellulose nanofibril contains an anionic functional group in at least a portion thereof, and
wherein the cationic hectorite nanoplate particle structure is disposed in contact with an oil phase and the anionic cellulose nanofibril is disposed in contact with a water phase, and forms the coacervate interfacial film by electrostatic interaction between the cationic surfactant and the anionic functional group.
