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.

L'invention concerne une composition cosmétique, en particulier pour la photoprotection de la peau et/ou des cheveux, sous forme de dispersion comprenant deux phases non miscibles stabilisées par au moins un tensio-actif anionique choisi parmi les sels d'acides gras et de métaux mono- ou polyvalents, d'ammonium ou de bases organiques, un composé filtrant le rayonnement ultraviolet susceptible d'être adsorbé à l'interface desdites phases non miscibles, dérivé du benzylidène camphre et comprenant au moins une fonction acide sulfonique partiellement ou totalement neutralisée, un nanopigment d'oxyde métallique enrobé avec des agents d'enrobage hydrophobes hydrocarbonés et un composé cationique ou zwitterionique amphiphile qui conduit avec le tensio-actif anionique à la formation d'un composé capable d'abaisser la tension interfaciale eau/huile de paraffine à 40 °C de plus de 14 mN.m-1 pour une concentration de tensio-actif anionique de 0,1 mmole/100g, de plus de 26 mN.m-1 pour une concentration de tensio-actif anionique de 0,5 mmole/100g et de plus de 33 mN.m-1 pour une concentration de tensio-actif anionique de 1 mmole/100g.
