Abstract
Disclosed is a liquid aqueous alcoholic antiperspirant composition comprising, by weight, about 10% to about 60% ethanol, water, and about 8% to about 22% (USP) antiperspirant salt dissolved in the composition, wherein said antiperspirant salt comprises a calcium enhanced aluminum-zirconium chlorohydrate. The composition may optionally include a thickening agent to increase the viscosity of the solution. A more viscous solution is less prone to dripping from the skin or leaking from the dispensing container. Ideally, the composition will provide an absolute sweat reduction significantly higher than currently available antiperspirant products, typically at least 60% sweat reduction or higher.
