Abstract
The invention relates to a composition comprising in an aqueous phase, particles having a diameter in the range of 20 to 500 nm, said particles containing:—an oil phase;—in said oil phase,—an aqueous droplet, or—a nanocapsule (NC) comprising:—an aqueous core, and—a polymeric shell or a shell composed of an amphiphilic substance; and—a surfactant. This composition is particularly useful for encapsulating hydrophilic and/or lipophilic substances.
