Abstract:
Anhydrous antiperspirant gel-solid stick compositions comprising:(A) from about 0.5% to about 60% by weight of particulate antiperspirant active;(B) from about 1% to about 15% by weight of a solid non-polymeric gellant that contains zero percent of organic polymeric gellants, inorganic thickening agents, dibenzylidene alditol, n-acyl amino acid amides, n-acyl amino acid esters, or combinations thereof; and(C) from about 10% to about 80% by weight of an anhydrous liquid carrier having an average solubility parameter of from about 3 to about 13 [cal/cm.sup.3 ].sup.0.5 andwherein the composition has a visible residue index of from about 11 to about 30 L-value, a product hardness of from about 500 gram-force to about 5,000 gram-force, and a ratio of an elastic to viscous moduli of from about 0.1 to about 100, and wherein the refractive indices of the particulate antiperspirant active, the solid non-polymeric gellant, and the anhydrous liquid carrier are not matched, and wherein the solid-nonpolymeric gellant are elongated crystalline particles having an aspect ratio of at least 2 and an average particle size of less than about 1 .mu.m.
