ABSTRACT:
Antiperspirant compositions comprising aluminum and zirconium. Efficacious, aqueous solution-stable, antiperspirant complexes comprise an aluminum compound, a zirconium compound, a water soluble neutral amino acid, and an inorganic acidic compound. The aluminum compound is an aluminum chlorohydrate having an aluminum to chlorine molar ratio of from about 1.60 to about 2.5 while the zirconium compound is a zirconyl hydroxychloride having a zirconium to chlorine molar ratio of from about 0.67 to about 2.0. In the antiperspirant complex, the aluminum to zirconium molar ratio is from about 2 to about 10, the total metal to chlorine molar ratio is less than about 1.30, and the neutral amino acid to total metal molar ratio is from about 0.09 to about 0.24. The neutral amino acid to total metal molar ratio is from about 0.09 to about 0.75 when the antiperspirant complex is used in non-aqueous systems.
