A composition (c1) in the form of an oil-in-water emulsion, with an oily phase dispersed in an aqueous phase, comprises an emulsifying system containing at least one nonionic surfactant with a melting point of less than 45[deg]C and an HLB ranging of 10 - 15, and at least one anionic surfactant; and at least one hydrophilic UV-screening agent. A composition (c1) in the form of an oil-in-water emulsion, with an oily phase dispersed in an aqueous phase, comprises an emulsifying system containing at least one nonionic surfactant with a melting point of less than 45[deg]C and an HLB ranging of 10 - 15, and at least one anionic surfactant; and at least one hydrophilic UV-screening agent. The surfactant with a polar portion contains at least 5 oxyethylene groups and an apolar portion contains at least one branched or unsaturated 14-22C alkyl chain. The oily phase comprises oily constituents that includes (wt.%): at least one hydrocarbon-based oil (h1) with a molecular weight of >= 400 (at least 25) and triglyceride-based oils (less than 15). The weight ratio of the amount of oily constituents of the oily phase to the amount of emulsifying system is 0.8 - 3.5. Independent claims are included for the following: (1) an article obtained by impregnating a water-insoluble substrate with (c1); and (2) a process for preparing the (c1) involving preparing the oily phase (A) comprising the oil(s) and other fatty substances, and the emulsifying system with stirring at 20 - 45[deg]C until a homogeneous phase is obtained, introducing into phase (A) 0.1 - 3 wt.% of water (phase B) and mixing until a homogeneous phase (C) is obtained, adding to phase (C) 55 - 75 wt.% water (phase D) to obtain after mixing a homogeneous phase E, and optionally adding any further constituents of the aqueous phase (phase F). - ACTIVITY : Dermatogical. - MECHANISM OF ACTION : None given.
