Abstract

La présente invention concerne une composition cosmétique de type eau dans huile à haute phase interne et, plus précisément, une composition cosmétique utilisant un émulsifiant comprenant un polymère réticulé lié par un coupleur hydrophile et un polymère ramifié lié par un coupleur hydrophile, permettant d'optimiser la sensation d'hydratation du fait de sa haute phase interne aqueuse tout en présentant la propriété physique d'être de faible viscosité, ce qui facilite l'imprégnation dans un vecteur.
