LA PRESENTE INVENTION CONCERNE UNE COMPOSITION SOLAIRE FILTRANTE COMPRENANT AU MOINS UN AGENT OLEOSOLUBLE ABSORBANT LES RAYONS UV AINSI QU'AU MOINS UN POLYISOBUTYLENE LIQUIDE A TEMPERATURE AMBIANTE, DE POIDS MOLECULAIRE MOYEN VISCOSIMETRIQUE COMPRIS ENTRE 8000 ET 65000, DANS UN MILIEU COSMETIQUEMENT ACCEPTABLE COMPORTANT AU MOINS UNE PHASE GRASSE. UNE TELLE COMPOSITION ANTISOLAIRE, APPLIQUEE SUR LA PEAU, PRESENTE UN INDICE DE PROTECTION AMELIORE. The present invention relates to a sunscreen composition containing at least one oil-soluble agent absorbing UV rays as well as at least one polyisobutylene which is liquid at ambient temperature, with a viscosity-average molecular weight of between 8,000 and 65,000, in a cosmetically acceptable medium incorporating at least one fatty phase. Such a suncreen composition, applied on the skin, has an improved protection index.
