Abstract (en)
[origin: WO2018172433A1] The present invention relates to a method for preparing solid microcapsules comprising the following steps: a) preparing a composition C1, which is either a composition C1a, comprising a single hydrophobic solid particle, or a composition C1b comprising a plurality of dispersed hydrophobic solid particles in a hydrophilic phase, b) adding, under agitation, the composition C1 to a polymeric composition C2 at a temperature Tb, whereby an emulsion (E1) is obtained; c) adding, under agitation, the emulsion (E1) to a composition C3 at a temperature Tc, whereby a double emulsion (E2) is obtained; d) applying shear to the emulsion (E2), whereby a double emulsion (E3) is obtained; and e) polymerising the composition C2, whereby solid microcapsules dispersed in the composition C3 are obtained.
