Abstract

Disclosed are methods of making anhydrous antiperspirant gel-solid stick compositions comprising an particulate antiperspirant active; a solid non-polymeric gellant that is substantially free of dibenzylidene alditol, n-acyl amino acid derivatives, organic polymeric gellants, and inorganic thickening agents; and an anhydrous liquid carrier having an average solubility parameter of from about 3 to about 13 (cal/cm.sup.3).sup.05,wherein the composition has a visible residue index of from about 11 to about 30 L-value, a product hardness of from about 500 gram.multidot.force to about 5,000 gram.multidot.force, a ratio of an elastic to viscous moduli of from about 0.1 to about 100. The refractive indices of the particulate antiperspirant active, solid non-polymeric gellant, and anhydrous liquid carrier are not matched. The solid non-polymeric gellant is preferably a crystalline material having an average particle size of less than about 1 .mu.m, and/or has an elongated particle morphology having an aspect ratio of greater than about 2. These antiperspirant gel-solid stick compositions made in accordance with the methods herein provide improved low residue performance, efficacy and aesthetics.
