摘要：
Methods for making antiperspirant products in the form of emulsions are provided, wherein the emulsion comprises a continuous water-immiscible phase and a disperse aqueous phase comprising an antiperspirant active. The method comprises the steps of providing a water-immiscible liquid, providing an aqueous solution comprising an antiperspirant active, preparing an emulsion comprising a continuous phase including the water-immiscible liquid and a disperse phase including the aqueous solution, heating the emulsion to a temperature between about 60° C. and about 110° C., providing a structurant that is at least partially dissolved, adding the heated emulsion to the at least partially dissolved structurant to form an emulsified antiperspirant composition, and transferring the emulsified antiperspirant into a dispensing container within about 2 hours of initiating the heating step.
