Abstract

La présente invention concerne un procédé de préparation de microcapsules solides comprenant les étapes suivantes : a) la préparation d'une composition C1, comprenant au moins une substance hydrosoluble ou hydrophile dispersée dans une phase hydrophobe, b) l'addition sous agitation de ladite composition C1 dans une composition polymérique C2, les compositions C1 et C2 n'étant pas miscibles l'une dans l'autre, ce par quoi on obtient une émulsion (E1); c) l'addition sous agitation de l'émulsion (E1) dans une composition C3, les compositions C2 et C3 n'étant pas miscibles l'une dans l'autre, ce par quoi on obtient une émulsion double (E2); d) l'application d'un cisaillement à l'émulsion (E2), ce par quoi on obtient une émulsion double (E3); et e) la polymérisation de la composition C2, ce par quoi on obtient des microcapsules solides dispersées dans la composition C3.
