Disclosed is a packaged antiperspirant cream composition comprising a gellant, a liquid carrier, an antiperspirant active, and a dispensing package which contains the antiperspirant cream composition. The packaged antiperspirant cream compositions have improved stability, application aesthetics, and reduced syneresis. The dispensing package comprises 1) a container body having an interior chamber of generally uniform or symmetrical cross section which contains the antiperspirant cream composition and has a lengthwise extending axis, 2) an elevator having a cross section congruent to and mounted for axial movement within the interior chamber, 3) a perforated, convex dome attached to a dispensing end of the container body and having a plurality openings extending through the thickness of the perforated dome, 4) a means for axially advancing the elevator toward the perforated dome; and 5) an optional means for axially reciprocating the elevator away from the convex dome; wherein the means for axially advancing the elevator and the optional means for axially reciprocating the elevator cooperate to reciprocate the elevator a minimum distance Dmin. The dispensing package preferably has a select container body rigidity, a select convex configuration for the perforated dome and supporting elevator, and/or other means for reducing residual internal pressure, all of which help to minimize the development of solvent syneresis from the antiperspirant cream composition.
