    FR 3 060 979 - A1 ® OIL-IN-WATER EMULSION COMPRISING A PARTICULAR SURFACTANT SYSTEM.
    @) The subject of the invention is a cosmetic composition in the form of an oil-in-water emulsion comprising:
    (i) at least one lipophilic surfactant of HLB less than or equal to 9, and (ii) at least one particular anionic surfactant comprising at least one sulfate and / or sulfonate function;
    said composition comprising from 0% to 8% by weight of additional surfactant (s) relative to the total weight of the composition.
    It also relates to the associated cosmetic process.
    The invention relates to a cosmetic composition in the form of an oil-in-water emulsion comprising a lipophilic surfactant of HLB less than or equal to 9 and a particular anionic surfactant comprising at least one sulfate and / or sulfonate function.
    The invention also relates to a cosmetic treatment process for keratin materials comprising the application of said composition.
    It is known from documents WO2013076691 and EP 1 917 954, oil-in-water emulsions comprising an ester of polyglycerol and fatty polyacids such as 2-polyglyceryl-dipolyhydroxystearate as lipophilic surfactant and an alkylpolyglucoside such as lauryl glucoside as hydrophilic surfactant. These emulsions have the peculiarity of reversing phase when applied to keratin materials. However, the combination of surfactants described in these two documents does not make it possible to obtain stable compositions within the meaning of the present invention. Also, these compositions have a reduced duration of application or "playtime" due to a too rapid phase inversion during application to keratin materials, this reduction in the duration of application generates a difficulty in correctly spreading the composition on the skin and does not favor obtaining a homogeneous deposit, in particular when the composition comprises pigments.
    In addition, it is also known from document WO2015117841 oil-in-water emulsions having the property of reversing phase during application to keratin materials comprising an ester of polyglycerol and of fatty polyacids such as polyglyceryl-2 dipolyhydroxystearate as a lipophilic surfactant and a surfactant comprising a sulfonated function such as disodium cetearyl sulfosuccinate as a hydrophilic surfactant. However, the compositions described in this document also have a reduced duration of application or "playtime" as mentioned above.
    The present invention therefore aims to provide compositions in the form of an oil-in-water emulsion having a phase inversion on application and having a satisfactory duration of application to keratin materials, preferably the skin.
    Furthermore, the present invention also aims to provide compositions in the form of an oil-in-water emulsion having a phase inversion on application, having good stability properties, in particular having better stability in comparison with lauryl glucoside and polyglyceryl-2 dipolyhydroxystearate as described in documents WO2013076691 and
    EP 1,917,954.
    The term “playtime” or “duration of application” is understood to mean the duration during which the composition remains sufficiently fluid to be applied to keratin materials. A playtime is said to be satisfactory when the duration of application is between 45 and 75 seconds, preferably between 50 and 70 seconds, even better between 55 and 70 seconds, in particular as indicated in the examples below.
    A composition is said to be stable when little or no change in its macroscopic and / or microscopic appearance and / or in its physicochemical characteristics (viscosity) is observed after storage at room temperature (25 ° C.) for a period of one month, preferably 2 months and / or after storage at a temperature of 55 ° C for a period of 15 days.
    The viscosity is measured at 25 ° C., using a RHEOMAT RM 180 viscometer equipped with a mobile No. 3, the measurement being carried out after 10 minutes of rotation of the mobile within the composition (time at the end of which there is a stabilization of the viscosity and of the speed of rotation of the mobile), at a shear of 200 s 4
    The Applicant has surprisingly discovered that the combination of at least one particular anionic surfactant comprising at least one sulfate and / or sulfonate function, and at least one lipophilic surfactant of HLB less than or equal to 9, makes it possible to obtain a composition in the form of an oil-in-water emulsion which reverses in phase during its application to keratin materials, in particular to the skin, and having a satisfactory duration of application to keratin materials, preferably the skin.
    Furthermore, the composition according to the invention has good stability properties.
    In addition, the composition according to the invention also has good cosmetic properties, in particular a feeling of freshness on application as well as a lighter and less oily feel after application.
    Thus, the present invention relates to a cosmetic composition in the form of an oil-in-water emulsion comprising:
    (i) at least one lipophilic surfactant of HLB less than or equal to 9;
    (ii) at least one anionic surfactant comprising at least one sulfate and / or sulfonate function;
    said anionic surfactant comprising at least one sulfonate function is chosen from alkyls (C6-C30) sulfonates, alkyls (C6-C30) amidesulfonates, alkyls (C6-C30) arylsulfonates, alpha-olefin sulfonates, paraffinsulfonates , alkyl (C6-C30) sulfoacetates, N-acyl (C6-C30) -N-alkyl (Cl-C6) taurates, acyl (C6-C30) isethionates, alkyl (C6-C30) sulfolaurates, and their mixtures, said composition comprising from 0% to 8% by weight of additional surfactant (s) relative to the total weight of the composition.
    The composition according to the invention is intended for topical application and therefore contains a physiologically acceptable medium. The term “physiologically acceptable medium” is understood here to mean a medium compatible with human keratin materials such as the skin, the mucous membranes, the scalp.
    The present invention also relates to a cosmetic treatment process for keratin materials, characterized in that a composition in accordance with the present invention is applied to said keratin materials, in particular the skin and in particular the skin of the face and / or of the body.
    In the present application, the expression “at least one” is equivalent to “one or more” and, unless otherwise indicated, the limits of a range of values are included in this range .
    PHASE INVERSION TECHNOLOGY
    The oil-in-water emulsion composition according to the invention has the property of reversing phase during its application to keratin materials due to the shear generated during its spreading with the fingers, with a sponge, or with a brush. , preferably with the fingers, in other words thanks to the mechanical energy induced by the gestures of the user during application.
    With the phase reversal which occurs during the application of the composition according to the present invention to keratin materials, preferably on the skin, a lipophilic film is obtained more quickly on the skin compared to the application of an oil-in-water composition with simple evaporation of the aqueous phase without phase inversion.
    Also, the oil-in-water emulsion according to the invention has, during application to the skin, good penetration properties, a feeling of freshness, and a less greasy, less sticky and lighter finish after application.
