A process for preparing oxo-hexameric zirconium-octaamino acid, such asglycine, salt comprising: mixing zirconium(Zr): amino acid : and mineral acid, in a molar ratio of 1: about 1 to about15: about 1.5 to about 3 to form a mixture optionally,filtering the mixture and optionally, drying the mixture. An oxo-hexamericzirconium-octaamino acid salt of the molecular formula:oxo- [Zr6 Amino Acid8].cndot.X y .cndot. nH2O, wherein Zr is zirconium, X isan anion of a mineral acid, and n and y are numerical values from0 to 20. A method of making an antiperspirant active zirconium-aluminum-aminoacid compound comprising mixing an oxo-hex-americ zirconium-octaamino acid salt with aluminum chlorohydrex and/oraluminum chloride, and drying the mixture. The smallestoxo-hexameric zirconium-octaamino acid salt of this invention providesstability, efficacy, and shelf life of zirconium-amino acidspecies for formulations in antiperspirant and/or deodorant compositions.
