Low residue antiperspirant gel-solid stick compositions containing volatile nonpolar hydrocarbon solvents

Abstract

Disclosed are anhydrous antiperspirant gel-solid sticks which comprise from about 0.5% to about 60% by weight of antiperspirant active; from about 1% to about 15% by weight of a gellant; from about 1% to about 50% by weight of nonpolar volatile hydrocarbon solvent having a solubility parameter of less than 8 (cal/cm.sup.3).sup.0.5, a vapor pressure of from about 0.0 1 mmHg to about 6 mmHg, and an average boiling point of less than about 250.degree. C.; and from about 0.01% to about 10% by weight of a polar, water-miscible solvent having a solubility parameter of from 12.5 (cal/cm.sup.3).sup.0.5 to about 25 (cal/cm.sup.3).sup.0.5 ; 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.cndot.force to about 5,000 gram.cndot.force, and a ratio of an elastic to viscous moduli of from about 0.1 to about 100. These compositions provide improved low residue performance, rheology, efficacy, stability and/or aesthetics from a composition having reduced raw material costs.
