Zusammenfassung:A cosmetic composition comprising Janus particles, an aqueous phase and an organic phase uses Janus particles produced with a method which includes the preparation of hollow particles (1) having two non-continuous surfaces of a material with surface energy α, of which the external one (2) is accessible and the internal one (3) is inaccessible. The surface energy of the external surface (2) is thereby modified originating particles (11) with internal surface energy α and external surface energy β. The modified particles (11) are then ground until particles are obtained constituted by small fragments (21) shaped as spherical caps with external surface (12) having modified energy and internal surface (13) having non-modified internal energy.
