The present invention relates to a material obtainable by the sol-gel route, having a maximum absorption wavelength (lambdamax) in the range from 370 to 400 nm, said material comprising at least one UV solar filter. -A organic having a lambdamax of less than 370 nm, at least one zirconium alkoxide, at least one functionalized organic polymer or a precursor of such a polymer, or at least one functionalized silicone polymer or a precursor of such a polymer, at least less a solvent and a sufficient quantity of water for the partial and / or total hydrolysis of the zirconium alkoxide and its condensation. The present invention also relates to a method for shifting in the range from 370 to 400 nm, the maximum absorption wavelength of an organic UV-A sunscreen having a lambdamax less than 370 nm, as well as a cosmetic and / or dermatological composition for photoprotection of the skin and / or keratin materials, comprising a material of the invention. |
