USE OF NITROGEN-DOPED TITANIUM OXIDE NANOPARTICLES AS AGENTS FOR PROTECTING AGAINST ULTRAVIOLET RADIATION

摘要

The invention relates to the use of a nanometric material based on nitrogen-doped titanium oxides, especially obtained by injecting a titanium oxide precursor in a liquid or gaseous form, in addition to a gaseous nitrogenated compound, into a laser pyrolysis reactor, as a cosmetic agent for protecting against ultraviolet radiation. The invention also enables protection against UVs and especially UVAs to be improved.
