    摘要: A process for making a solid cosmetic composition, the process comprising the steps of: forming at least one hot process stream comprising a solvent and a gellant dissolved therein, the hot process stream having a first temperature; forming at least one cold process stream comprising a cosmetic active having a second temperature, wherein the second temperature is at least 5 degrees C below the first temperature; combining the at least one hot process stream and the at least one cold process stream together in a mixing chamber having no moving parts therein and without applying external source of cooling, to form a substantially homogeneous product stream.
