Publication number: 20040115147Abstract: 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.Type: ApplicationFiled: December 16, 2002Publication date: June 17, 2004Applicant: The Gillette CompanyInventors: Tuan M. Vu, Yan-Fei Shen

Patent number: 6726901Abstract: Disclosed is an anhydrous topical antiperspirant composition comprising a dermatologically acceptable carrier and a perspiration reducing effective amount of a particulate antiperspirant salt suspended in the carrier. The antiperspirant salt comprises an aluminum-zirconium chlorohydrate having a metal to chloride ratio between about 0.9 and about 1.3. The composition also includes, separate from the antiperspirant salt, a stabilizing basic material in an amount sufficient to prevent degradation of the antiperspirant composition or to minimize acid odor. Also disclosed is a method of reducing perspiration from human skin by applying the aforementioned topical composition.Type: GrantFiled: May 9, 2002Date of Patent: April 27, 2004Assignee: The Gillette CompanyInventors: Yuling Yin, Jayant N.
