COSMETIC OR DERMATOLOGICAL WATER-IN-OIL EMULSION COMPRISING A MEROCYANINE AND AT LEAST ONE EMULSIFYING POLYMER OF THE POLYOXYALKYLENATED GLYCOL FATTY ACID ESTER TYPE
The present invention relates to a cosmetic or dermatological composition in the form of a water-in-oil emulsion comprising, in a physiologically acceptable support: a) at least one aqueous phase, and b) at least one oily phase, and c) at least one merocyanine compound of formula (1 ) or one of the E/E- or E/Z- geometrical isomer forms thereof formula (1) in which R is a C1-C22 alkyl group, a C2-C22 alkenyl group, a C2-C22 alkynyl group, a C3-C22 cycloalkyl group or a C3-C22 cycloalkenyl group, it being possible for the said groups to be interrupted with one or more O and d) at least one emulsifying system comprising at least one emulsifying polymer of the polyoxyalkylenated glycol fatty acid ester type. The invention also relates to a non-therapeutic cosmetic process for caring for and/or making up a keratin material, consisting in applying, to the surface of the said keratin material, at least one composition according to the invention as defined above. The invention also relates to a non-therapeutic cosmetic process for limiting the darkening of the skin, improving the colour and/or uniformity of the complexion, comprising at least the application, to the surface of the keratin material, at least one composition as defined previously. The invention also relates to a non-therapeutic cosmetic process for treating the ageing of a keratin material, comprising at least the application, to the surface of the keratin material, at least one composition as defined previously.La présente invention concerne une composition cosmétique ou dermatologique sous la forme dune émulsion deau dans lhuile comprenant, dans un support physiologiquement acceptable : a) au moins une phase aqueuse et b) au moins une phase huileuse, et c) au moins un composé de mérocyanine de formule (1) ou une des formes disomère géométrique E/E ou E/Z de celui-ci : formule (1) dans laquelle : R est un groupe alkyle en C1-C22, un groupe alcényle en C2-C22, un groupe alcynyle en C2-C22, un groupe cycloalky
