The invention concerns a cosmetic composition, in particular for skin and/or hair protection, in the form of a dispersion comprising two non-miscible phases stabilised by at least an anionic surfactant selected among the salts of fatty acid and of monovalent or polyvalent metals, of ammonium or organic bases, a compound filtering ultraviolet radiation capable of being adsorbed at the interface of said non-miscible phases, derived from benzylidene camphor and comprising at least a sulphonic acid function partially or completely neutralised, a metal oxide nanopigment coated with hydrocarbon hydrophobic agents and an amphiphilic cationic or dipolar ion compound which leads with the anionic surfactant to the formation of a compound capable of lowering the water/paraffin oil interfacial tension at 40 DEG C by more than 14 mN.m<-1> for an anionic surfactant concentration of 0.1 mmole/100g, by more than 26mN.m<-1> for an anionic surfactant concentration of 0.5 mmole/100g and by more than 33 mN.m<-1> for an anionic surfactant concentration of 1 mmole/100g. |
