Abstract
La présente invention concerne un procédé de préparation d'une émulsion doub le monodisperse, de type eau dans huile dans eau, caractérisé en ce qu'il comprend les étapes consistant à: a) soumettre une émulsion Ei de type eau dans huile, polydisperse, comprenant de 50 à 99% en poids d'une phase aqueus e, à un cisaillement contrôlé de telle sorte qu'un même cisaillement maximal so it appliqué à l'ensemble de l'émulsion, de façon à obtenir l'émulsion inverse monodisperse correspondante; b)ajouter à ladite émulsion, sans inversion de phase, la quantité nécessaire d'une phase huileuse de dilution de façon à ce que la phase aqueuse de l'émulsion résultante représente moins de 50 % en poids du poids total de l'émulsion; c) et introduire l'émulsion résultante dans un homogénéisateur haute pression, ensemble avec une phase aqueuse continue, les quantités respectives de ladite émulsion et de ladite phase aqueuse continue étant telles que l'émulsion double résultante comprend jusqu'à 50% en poids de gouttelettes d'émulsion inverse par rapport au poids total de l'émulsion, ladite phase aqueuse continue comprenant une concentration en tensioactif hydrophile intérieure ou égale à 0.02 fois la concentration micellaire critique.
