Anti-sun composition in the form of an oil-in-water emulsion comprising at least one mixture of surfactants The present invention relates to a composition in the form of an oil-in-water emulsion comprising a) at least one continuous aqueous phase, b) at least one oily phase dispersed in said aqueous phase, c) at least one mixture of surfactants comprising i) one or more fatty acid esters of a polyalkylene glycol, ii) one or more fatty acid esters of glycerol, iii) one or more fatty acids in free form and iv) one or more alkali metal salts of anester of phosphoric acid and of a fatty alcohol, and d) one or more UV-screening agents. The present composition has a viscosity of less than or equal to 0.10 Pa·s at a temperature of 25° C., the viscosity being measured using a Rheomat 180 (from the company Lamy), equipped with an MS-R1, MS-R2, MS-R3, MS-R4 or MS-R5 spindle chosen according to the consistency of the composition, rotating at a rotation speed of 200 rpm. The present invention also relates to a non-therapeutic cosmetic process for limiting the darkening of the skin and/or improving the colour and/or uniformity of the complexion, comprising the application, to the surface of the skin, of at least one composition as defined previously. The present 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.
