Embodiment

[0497] Example of Ultrasonic Treatment

[0498] Series 1: Silicone resin bowl-shaped particles ( diameter : 2.3μm±0.9 ) prepared emulsion

[0499] Sonicator XL instrument from Misonix Incorporated at 110W to 165W power for 1 minute to 1 minute 5 seconds; 25°C.

[0500]

[0501]

[0502]

[0503] Preparation scheme:

[0504] The emulsion was prepared by sonication in two steps:

[0505] - for 35s to form the "start" phase of the interface,

[0506] -Then add particles for a 30 s "end of step" phase.

[0507] The power applied is specific to each emulsion in the table above.

[0508] Series 2: Use PMMA bowl-shaped particles ( diameter : 11.8μm±1.5 ) prepared emulsion

Abstract

The present invention relates to an oil / oil emulsion comprising at least: - a first oil phase comprising at least a first non-volatile oil selected from silicone oils, hydrocarbon-based oils and fluoro oils, - comprising at least The second oil phase of the second volatile or non-volatile oil - having at least one bend and at least one curvature fractured solid particles of said bend. The invention also relates to cosmetic compositions comprising at least one such oil / oil emulsion in a physiologically acceptable medium. Finally, the invention relates to the use of solid particles having at least one bend and at least one curvature break of said bend for stabilizing an oil / oil emulsion as already described.

Description

technical field [0001] The present invention relates to the field of cosmetic compositions based on oil / oil (O / O) emulsions. Background technique [0002] There is still a need for novel architectures that can result in stable cosmetic compositions with the comfort properties desired by the user. [0003] The authors of the present invention conducted directed research on O / O emulsions. These emulsions are relatively rare, but have the advantage of novel properties. [0004] The main problem that arises with this type of emulsion is related to its stability: O / O emulsions are usually stabilized with gelling agents or even emulsifying surfactants and / or (co)polymers. [0005] Emulsions of this type are used especially in lip balms and / or lip makeup products. For example, patent application WO 2009 / 150852 relates to oil-in-oil cosmetic compositions comprising non-volatile hydrocarbon-based oils, non-volatile silicone oils and fatty acid esters of dextrins, but said applicat...
