Abstract

La présente invention concerne un procédé de préparation de microcapsules solides, comprenant les étapes suivantes : a) l'addition sous agitation d'une composition C1, comprenant au moins un actif, 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) comprenant des gouttes de composition C1 dispersées dans la composition C2 ; b) 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) comprenant des gouttes dispersées dans la composition C3 ; c) l'application d'un cisaillement à l'émulsion (E2), ce par quoi on obtient une émulsion double (E3) comprenant des gouttes de taille contrôlée dispersées dans la composition C3 ; et d) la polymérisation de la composition C2, ce par quoi on obtient des microcapsules solides dispersées dans la composition C3.
