Abstract
Disclosed are antiperspirant compositions, particularly clear gel antiperspirant compositions, that are water-in-silicone oil emulsions. The emulsion includes a water phase, typically comprising about 65% to about 95% by weight of the emulsion, and a silicone oil phase, typically comprising about 5% to about 35% by weight of the emulsion. The water phase includes an antiperspirant salt dissolved therein, typically in an amount of about 8% to about 30% by weight of the emulsion, the antiperspirant salt comprising a calcium enhanced aluminum-zirconium chlorohydrate. The silicone oil phase contains less than about 5% by weight of the emulsion of a non-volatile oil and includes about 2% to about 25% by weight of the emulsion of a volatile linear silicone.
