Abstract: Disclosed are enhanced efficacy antiperspirant compositions containing a strontium salt and/or a calcium salt. In particular, there is disclosed an antiperspirant composition comprising a dermatologically acceptable carrier vehicle, about 8% to about 22% (USP) of an aluminum-zirconium chlorohydrate-gly antiperspirant salt, wherein the antiperspirant salt has an HPLC peak 5 area of at least 33%, and about 0.5% to about 15%, preferably about 1% to about 6%, by weight, of a water soluble salt selected from the group consisting of a water soluble strontium salt, a water soluble calcium salt and a mixture thereof. It has been found that the inclusion of a strontium salt and/or a calcium salt boosts the efficacy of a high peak 5 antiperspirant salt. As a preferred feature, the antiperspirant salt and the water soluble salt are dissolved in at least a portion of the carrier vehicle.
