摘要
The present invention relates to a method for preparing solid microcapsules that comprises of the following steps of preparing a composition C1, comprising at least one water-soluble or hydrophilic substance dispersed in a hydrophobic phase; adding, under agitation, of the said composition C1 in a polymeric composition C2, the compositions C1 and C2 being immiscible with each other, whereby an emulsion (E1) is obtained; adding, under agitation, of the emulsion (E1) in a composition C3, the compositions C2 and C3 being immiscible with each other, whereby a double emulsion (E2) is obtained; shearing the emulsion (E2), whereby a double emulsion (E3) is obtained; and polymerizing the composition C2, wherein solid microcapsules dispersed in the composition C3 are obtained.
