Patent number: 5346694Abstract: Antiperspirant compositions in the form of gel sticks, which provide the user with excellent antiperspirant efficacy while exhibiting good stability, are disclosed. Specifically, the compositions have an acidic pH and include an antiperspirant active, a gelling agent which comprises dibenzylidene alditols, a solvent for the gelling agent, and a gelling agent stabilizer which is a basic metallic salt of an acid having a pKa of from about 3.8 to about 6.5 at 25.degree. C, said salts being at least partially soluble in the composition, and said stabilizer being a salt selected from the group consisting of C.sub.4 -C.sub.6 alkyl dicarboxylates, C.sub.6 -C.sub.8 alkyl monocarboxylates, and substituted and unsubstituted benzoates, and mixtures thereof, wherein said gelling agent stabilizer does not contain amino or amido functionalities. Methods of preventing and controlling perspiration wetness using these compositions and of making the compositions are also disclosed.Type: GrantFiled: April 14, 1993Date of Patent: September 13, 1994Assignee: The Procter & Gamble CompanyInventor: Prem S.

Patent number: 5330751Abstract: 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: October 3, 1990Date of Patent: July 19, 1994Assignee: The Gilette CompanyInventors: Maria A. Curtin, Alan M. Phipps

Patent number: 5320828Abstract: Encapsulated aluminum salts are produced by combining and heating an aqueous aluminum salt selected from aluminum halohydrate, aluminum nitrohydrate and mixtures thereof; a hydrophobic liquid; and a carboxylate. The mixture is heated until substantially all of the free water has been removed. The encapsulated aluminum salts precipitate out after the removal of the water. The encapsulated aluminum salts are useful in deodorant and antiperspirant compositions.Type: GrantFiled: June 8, 1993Date of Patent: June 14, 1994Assignee: Dow Corning CorporationInventors: Lori J.
