Claim:
1. A method for making an emulsified antiperspirant product comprising a continuous phase that includes a water-immiscible liquid and a disperse aqueous phase comprising an antiperspirant active, the method comprising the steps of: a. providing a water-immiscible liquid; b. providing a volatile aqueous solution comprising an antiperspirant active; c. combining the water-immiscible liquid and the aqueous solution to form an emulsion comprising a continuous phase including the water-immiscible liquid and a disperse phase including the aqueous solution; d. providing a structurant separate from the emulsion; e. adding the structurant to the emulsion to form an emulsified antiperspirant composition wherein the batch weight of the emulsified antiperspirant composition is greater than 20 kg; f. heating the emulsified antiperspirant composition to a temperature between about 60° C. and about 110° C. from about 15 minutes to less than about 2 hours to reduce the loss of the volatile aqueous solution; and g. transferring the emulsified antiperspirant composition into one or more dispensing containers.
