The present invention relates to the field of sun protection and more particularly to the use of: i) at least one bismuth oxycarbonate particle of empirical formula (I): (BiO)(CO), formula (I), and also solvates thereof such as hydrates, in which -0.4 < x < 0.6, for screening out ultraviolet radiation, the largest mean dimension of said particles being less than 400 nm; ii) at least one surfactant; it being understood that: - the mass ratio R of the sum of i) the bismuth oxycarbonate particles to ii) the sum of the surfactants is greater than or equal to 1, preferably R > 1; - when the surfactant is polysorbate 20, then R is other than 2/0.29, for screening out UV radiation, in particular UV-A and/or UV-B, notably UV-B screening agents, in particular for treating keratin materials, notably human keratin materials such as the skin, and/or keratin fibres, notably human keratin fibres such as the hair.
