摘要

The present invention relates to a cosmetic or dermatological composition comprising, in a physiologically acceptable support: a) at least one oily phase; b) at least one merocyanine compound corresponding to formula (1) below, and also the E/E-or E/Z-geometrical isomer forms thereof, 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, the said groups possibly being interrupted with one or more O, and c) at least one UVA-screening agent chosen from: (i) an amino-substituted 2-hydroxybenzophenone compound; (ii) a hydrophilic organic UVA-screening agent,and (iii) their mixtures; the said hydrophilic organic UVA-screening agent being present in an amount of greater than 0.5% by weight relative to the total weight of the composition. The present invention also relates to a non-therapeutic cosmetic process for caring for and/or making up a keratin material, comprising the application to the surface of the said keratin material of 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 and/or the improving the colour and/or the uniformity of the complexion, comprising the application to the surface of the keratin material of at least one composition as defined previously. The invention also relates to a non-therapeutic cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising the application to the surface of the keratin material of at least one composition as defined previously.
