Abstract
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.
Claims13
A method of solidifying a cosmetic composition comprising an antiperspirant or deodorant active, the method comprising the steps of:
- (a) providing a liquid gellant component in a first liquid solvent having a first temperature;
- (b) providing an active component dispersed in a second liquid solvent having a second temperature lower than the first temperature;
- (c) combining the liquid gellant component and the active component together so that the active component causes instantaneous cooling of the gellant component to a temperature of from 35° C. to 55° C., thereby crystallizing the gellant component, with the proviso that the cooling of the gellant is conducted with no external sources of cooling.
