Abstract: The present invention relates to a process for preparing solid microcapsules comprising the following steps: a) preparation of a composition C1, which is either a composition C1a, comprising a single hydrophobic solid particle, or a composition C1b comprising a plurality of hydrophobic solid particles dispersed in a hydrophilic phase, b) addition with stirring of the composition C1 in a polymeric composition C2 at a temperature Tb, whereby an emulsion (E1) is obtained; c) addition, with stirring, of the emulsion (E1) in a composition C3 at a temperature Tc, whereby a double emulsion (E2) is obtained; d) applying a shear to the emulsion (E2), whereby a double emulsion (E3) is obtained; and e) polymerization of the composition C2, whereby solid microcapsules dispersed in the composition C3 are obtained.

Abstract: The present invention relates to a method for preparing solid microcapsules that comprises of the following steps: a) the preparation of a composition C1, comprising at least one water-soluble or hydrophilic substance dispersed in a hydrophobic phase; b) the addition, under stirring, 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; c) the addition, under stirring, 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; d) the application of a shear to the emulsion (E2), whereby a double emulsion (E3) is obtained; and e) the polymerisation of the composition C2, whereby solid microcapsules dispersed in the composition C3 are obtained.
