Emulsiones de aceite/aceite que contienen partículas con una ruptura de curvatura, composiciones que las contienen, y uso de las partículas para estabilizar emulsiones O/O

The present invention relates to an oil/oil emulsion comprising at least: -a first oily phase comprising at least a first non-volatile oil chosen from silicone oils, hydrocarbon-based oils and fluoro oils, -a second oily phase comprising at least a second volatile or non-volatile oil, which is immiscible with the first oil(s) at room temperature, -solid microparticles having at least one curved part and at least one breakage of curvature of the said curved part. The invention also relates to a cosmetic composition comprising, in a physiologically acceptable medium, at least one such oil/oil emulsion. Finally, the invention relates to the use of solid microparticles having at least one curved part and at least one breakage of curvature of the said curved part, for stabilizing an oil/oil emulsion as has just been described.
