Abstract:
1. A process for making granular solids comprising: (a) providing a substantially anhydrous preparation, which is solid at room temperature and contains at least one cosmetic feed material; (b) liquifying the substantially anhydrous preparation to form a melt; (c) providing a vibrating casting plate used for droplet formation; (d) introducing the melt onto the vibrating casting plate to form melt droplets thereon; (e) providing a cooling medium; and (f) contacting the melt droplets with the cooling medium which is passed countercurrently to the melt droplets, thus forming the granular solids, and wherein the granular solids have a monodisperse particle size distribution and are substantially free of particles having a diameter of less than 0.3 mm.
