Abstract

See full text

The present invention relates to a method 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 under stirring of the composition C1 in a polymeric composition C2 at a temperature Tb, whereby an emulsion (E1) is obtained;c) addition, under 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; ande) the polymerization of the composition C2, whereby solid microcapsules dispersed in the composition C3 are obtained.
