Patent number: 5770186Abstract: A composition of zirconyl hydroxy chloride and aluminum chlorhydroxide in stable solid form having improved antiperspirant efficacy when dissolved in water is made by heating a 2-20% by weight aqueous solution containing at least the aluminum chlorhydroxide component of the composition at a temperature of at least 50.degree. C. until the ratio of the height of peak 4 at Kd=0.7 to that of peak 3 at Kd=0.5 as measured by gel permeation chromatography on cross-linked dextran is at least 2:1, then subjecting the solution to rapid drying to solid form.Type: GrantFiled: December 16, 1996Date of Patent: June 23, 1998Assignee: The Gillette CompanyInventors: David T. Callaghan, Alan M. Phipps, Stephen J. Provancal

Patent number: 5384117Abstract: A substantially clear, anhydrous suspension-type antiperspirant product includes an effective amount of an active antiperspirant component in particulate form suspended in an anhydrous vehicle such that there is no significant dissolution of the active antiperspirant ingredient in the vehicle, and the refractive indices of the active antiperspirant component and the vehicle are matched.Type: GrantFiled: November 12, 1992Date of Patent: January 24, 1995Assignee: The Gillette CompanyInventors: Tuan M. Vu, Thomas J. Krafton, Alan M. Phipps

Patent number: 5356612Abstract: Antiperspirant effectiveness of basic aluminum chloride is increased by mixing it with monosilicic acid in aqueous solution. The product can be dried to a solid, and the antiperspirant effectiveness does not decrease in contact with water. The product can also be characterized by size exclusion chromatography of its approximately 10% by weight aqueous solution. Zirconyl hydroxy chloride may also be present.Type: GrantFiled: July 6, 1993Date of Patent: October 18, 1994Assignee: The Gillette CompanyInventors: Maria A. Curtin, Alan M. Phipps
