Abstract
Abstract Antiperspirant stick compositions containing dibenzyl monosorbitol acetal in the presence of acidic antiperspirant-active salts, which are stable for extended periods of time at elevated temperatures; said sticks comprising (a) about 1 to 80 percent by weight of a reactive solvent; (b) about 0 to 75 percent by weight of a non-reactive solvent; (c) about 1 to 10 percent by weight of dibenzyl monosorbitol acetal; (d) about 0 to 35 percent by weight of an emollient; (e) about 5 to 25 percent by weight of an antiperspirant-active compound; (f) about 0 to 2.5 percent by weight of a C12-C20 fatty acid; and (g) 0.05 to 15 percent by weight of a gel stabilizer; said gel stabilizer being a member of the group consisting of magnesium sulfate, zinc acetate and hexamethylenetetramine and mixtures thereof.
