Stable, three-phase antiperspirant stick compositions having (1) a solid, shearable antiperspirant phase, (2) a gel phase comprising a polyhydric aliphatic alcohol gelled with soap, and (3) a barrier phase of specified minimum thickness separating the antiperspirant and gel phases comprising a water

Stable, three-phase antiperspirant stick compositions having (1) a solid, shearable antiperspirant phase, (2) a gel phase comprising a polyhydric aliphatic alcohol gelled with soap, and (3) a barrier phase of specified minimum thickness separating the antiperspirant and gel phases comprising a water-insoluble, alcohol-insoluble, high melting point wax and liquid emollient and which is relatively free of particulate materials. Such antiperspirant sticks provide effective antiperspirant performance as well as desirable application characteristics.

An antiperspirant composition in the form of a three-phase stick, said composition comprising: (A) from about 35% to 65% by weight of the composition of an antiperspirant phase comprising a solid, shearable vehicle which contains an astringent antiperspirant material; (B) from about 35% to 65% by we

An antiperspirant composition in the form of a three-phase stick, said composition comprising: (A) from about 35% to 65% by weight of the composition of an antiperspirant phase comprising a solid, shearable vehicle which contains an astringent antiperspirant material; (B) from about 35% to 65% by weight of the composition of a gel phase, said gel phase comprising I. from about 10% to 92% by weight of the gel phase of a polyhydric aliphatic alcohol containing 2 to 3 carbon atoms and from 2 to 3 hydroxy groups; II. from about 5% to 15% by weight of the gel phase of a gel forming agent selected from the group consisting of a sodium salt of a fatty acid containing 14 to about 18 carbon atoms and a potassium salt of a fatty acid containing from about 14 to about 18 carbon atoms; and (C) from about 1% to 10% by weight of the composition of an interjacent barrier phase contiguous to the gel phase and the antiperspirant phase, wherein the barrier phase has a thickness of at least about 0.005 inch and comprises: I. from about 10% to 40% by weight of the barrier phase of a water-insoluble, alcohol-insoluble high melting point wax or mixtures thereof which has a melting point of from about 150°F. to 215°F.; and II. from about 20% to 90% by weight of the barrier phase of a water-insoluble, liquid organic emollient, and wherein the barrier phase is relatively free of particulate materials and is free of materials capable of reducing the pH of the gel phase below about 9.5 in the region of the gel/barrier interface.
