Abstract
L'invention concerne un procédé de préparation d'une émulsion secondaire constituée de gouttelettes d'une phase A, dispersées dans une phase B, A n'étant pas miscible dans B, au départ d'une émulsion primaire polydisperse de formulation identique et constituée de gouttelettes de ladite phase A dispersées dans ladite phase B, les gouttelettes de l'émulsion secondaire présentant un diamètre dans tous les cas inférieur au diamètre des gouttelettes de l'émulsion primaire, caractérisé en ce que l'émulsion primaire de départ est viscoélastique et en ce qu'on soumet ladite émulsion primaire de départ à un cisaillement contrôlé de telle sorte qu'un même cisaillement maximal soit appliqué à l'ensemble de l'émulsion.
