A topical dispersion photoprotective cosmetic composition, in particular for skin and / or hair photoprotection, comprising two immiscible phases stabilized by at least one anionic surfactant chosen from among fatty acid and mono-opolivalent metals , of ammonium or organic bases, a compound that filters the ultraviolet radiation capable of being absorbed at the interface of said nomiscible phases, derived from benzylidene camphor and comprising at least one partially or totally neutralized sulfonic acid function, an oxidometallic nanopigment coated by hydrocarbon hydrophobic coating agents and an amphiphilic cationic or zwitterionic compound that leads with the anionic surfactant to form a compound capable of lowering the water / paraffin oil interface voltage to 40 * C of more than 14 mN.m-1 for a anionic detective concentration of 0.1 mmol / 100 g, more than 26 mN.m-1 for unaconce With an anionic surfactant of 0.5 mmol / 100 g, and more than 33 mN.m-1 for an anionic surfactant concentration of 1 mmol / 100 g. |
