Abstract
A method of emulsification of an oil phase in an aqueous continuous phase, by dispersing core-corona microparticles into the aqueous phase, adding the oil phase, and applying shearing force for a time sufficient to emulsify the resulting mixture. The core-corona microparticles are obtained by radical co-polymerization of a polyethylene oxide macromonomer with at least one hydrophobic acrylate monomer and at least one hydrophobic acrylamide monomer.
