Abstract: Nanocapsules that form emulsion particles and an emulsion composition including the nanocapsules are disclosed. The emulsion composition contains an aqueous phase; an oil phase; and emulsion particles surrounded by a plurality of non-amphiphilic nanocapsules located in the interface between the aqueous phase and the oil phase. The emulsion composition is capable of forming emulsion particles in an oil-in-water-type emulsion composition, without using a surfactant.
