Abstract (en)

[origin: WO2011007082A1] The invention relates to an emulsion that can be activated by ultrasounds, comprising, in an emulsion in an aqueous solution, microparticles (1) having a diameter (D) of less than 10 µm and containing an active agent and a gaseous precursor (3) in a liquid form, encapsulated by a first emulsifier (4). The microparticles contain nanoparticles (5) smaller than 1 µm, in an emulsion in the gaseous precursor, each nanoparticle comprising an inner liquid (6) that contains the active agent and is encapsulated by second emulsifier (7).
