Abstract
A granular solid with monodisperse particle size distribution is disclosed, which may be obtained by melting an essentially anhydrous composition, which is solid at room temperature and made from at least one cosmetic ingredient. A flow of the melt is dispersed into droplets by means of a casting plate and vibration and said droplets contacted with a cooling medium, which causes the solidification thereof.
Claims10
A granular solid with a monodisperse particle size distribution, obtainable by liquefying a predominantly anhydrous preparation which is solid at room temperature and comprises at least one cosmetic feed material, making a stream of the melt into droplets using a casting plate by vibration, and passing a cooling medium countercurrently to the droplets, which causes them to solidify.
A process for the preparation of granular solids with a monodisperse particle size distribution in which a predominantly anhydrous preparation which is solid at room temperature and which comprises at least one cosmetic feed material is liquefied, a stream of the melt is made into droplets using a casting plate by vibration and a cooling medium is passed countercurrently to the droplets, which causes them to solidify.
