Abstract
A method of manufacturing a packaged solid stick antiperspirant composition is provided. The method includes combining an antiperspirant active, one or more structurants and a surfactant to form a mixture, dispensing the mixture from a nozzle to fill a dispensing package, forming a solid stick antiperspirant composition within the dispensing package. The surfactant has a melt temperature that is greater than the crystallization onset temperature of the solid stick antiperspirant composition. The antiperspirant active and the surfactant are in contact for about 5 minutes or less from the moment that the antiperspirant active and the surfactant and the structurant are mixed until the moment that the mixture is dispensed from the nozzle.
