    专利说明:

    The subject of the present invention is a cosmetic composition, in particular for topical application, consisting of two distinct phases, an aqueous phase and a water-in-oil (W / O) or oil-in-water (O / W) emulsion phase. the composition comprising a specific emulsifier system, and said W / O emulsion comprising at least 20% by weight of the total weight of the oily phase composition. The present invention also relates to the use of said composition in the cosmetic or dermatological field, and in particular for the removal of makeup, cleaning and / or care of the skin, eyes and / or phaneres.
    Cosmetic compositions consisting of two distinct phases, in particular an aqueous phase and a phase comprising oily compounds, said phases being distinct and not emulsified one in the other at rest, are generally referred to as " two-phase compositions ". They are distinguished from emulsions by the fact that at rest, the two phases are distinct, instead of being emulsified one in the other. The use of these two-phase compositions requires prior agitation to form an emulsion, the latter must be of sufficient quality and stability to allow a uniform application of the two phases on the skin or the keratin material where it is applied. At rest, said phases must separate quickly and return to their initial state, this phenomenon being better known as "phase shift".
    A rapid phase shift (or demixing) of the two phases after their use is one of the desired qualities of two-phase compositions. Indeed, obtaining a rapid phase shift is desirable for various reasons, in particular because a poor separation of the two phases is perceived as unsightly by users. However, it has proved difficult to find phase shift agents which make it possible to obtain a good phase shift without the formation of foam in the oily phase of the biphase during stirring. However, this formation of foam is prohibitive for the user.
    In addition, with conventional two-phase compositions, an emulsion is not necessarily formed after stirring the composition, which results in unsatisfactory makeup removal, and leaves a greasy residue on the skin or the keratin material.
    There remains therefore the need for a two-phase composition consisting of two distinct immiscible phases which, after agitation and extemporaneous and ephemeral formation of the emulsion, has a rapid phase shift in two phases, without foaming. Such a two-phase composition must also, after prior stirring, form an ephemeral emulsion allowing the application of the composition and an effective makeup removal, and without formation of fatty residue on the skin or the keratin material.
    Surprisingly, the Applicant has developed a two-phase formulation having the desired qualities, that is to say, separating rapidly in two clear phases after use, without there being foaming in the oily phase. during agitation. This formulation forms an ephemeral emulsion after stirring, and allows an effective makeup removal without leaving a greasy residue.
    The present invention thus relates to a cosmetic composition consisting of an aqueous phase and a water-in-oil or oil-in-water emulsion, the composition comprising an emulsifying system comprising an inulin derivative, a lysophospholipid, a poloxamer, a polypropylene glycol buteth and a hydrogenated castor oil derivative, and the water-in-oil or oil-in-water emulsion comprising at least 20% by weight of the total composition weight of an oily phase.
    The cosmetic composition according to the invention consists of two distinct phases, an aqueous phase and a water-in-oil or oil-in-water emulsion phase, is easily emulsified by stirring and is easily extruded after stopping the stirring.
    The composition according to the invention is preferably intended for topical application.
    The composition according to the invention comprises a water-in-oil or oil-in-water emulsion and a distinct aqueous phase. These two phases are distinct, that is to say they are visible one above the other at rest, respectively. In addition, they are transparent at rest. Each of the phases may or may not be colored. After stirring, such a composition forms an oil-in-water emulsion ephemeral ready to use.
    The composition according to the invention comprises an oily phase, which is present in the water-in-oil or oil-in-water emulsion. This oily phase is present in an amount of at least 20% by weight of the total weight of the composition.
    The composition according to the invention also comprises a global aqueous phase, which corresponds to the totality of the aqueous phase present in the composition (ie the aqueous phase as such, as well as the aqueous phase of the water-in-oil emulsion or oil-in-water). Preferably, the overall aqueous phase: oily phase weight ratio is between 60 and 80: 20. In fact, in these ratios, the tests carried out show stable compositions, especially at D + 2 at room temperature.

Preferably, the oily phase is present between 20% and 40%, preferably between 25% and 35% by weight of the total weight of the composition, preferably about 30% by weight.
    The composition according to the invention further comprises an emulsifying system comprising an inulin derivative, a lysophospholipid, a poloxamer, a polypropylene glycol buteth and a hydrogenated castor oil derivative.
    This specific emulsifying system is well tolerated, allows effective removal of makeup, increases hydration, prevents the formation of foam and stabilizes the resulting emulsion. In addition, it allows to prepare the composition according to the invention cold.
    In particular, the poloxamer is all the more surprising that it avoids the formation of foam, which is not the case for other emulsifiers, as will be shown later comparative examples. In addition, the presence of polypropylene glycol buteth and a hydrogenated castor oil derivative stabilizes the water-in-oil emulsion, and a good phase difference between this emulsion and the aqueous phase.
