Abstract

An antiperspirant gel stick composition incorporating a gelling agent, including a primary gellant selected from the group consisting of 12-hydroxystearic acid, esters of 12-hydroxystearic acid, amides of 12-hydroxystearic acid, and mixtures thereof and a secondary gellant selected from the group consisting of n-acyl amino acid amide derivatives. The antiperspirant gel stick compositions further incorporate a liquid base material including a non-polar, volatile oil and a relatively polar, non-volatile co-solvent. The combination of the gelling agent and the co-solvent permit the utilization of relatively high levels of a non-polar volatile oils which provide a dry feel.
