Abstract
A process for preparing oxo-hexameric zirconium-octaamino acid, such as glycine, salt comprising: mixing zirconium (Zr):amino acid:and mineral acid, in a molar ratio of 1:about 1 to about 15:about 1.5 to about 3 to form a mixture; optionally, filtering the mixture; and optionally, drying the mixture. An oxo-hexameric zirconium-octaamino acid salt of the molecular formula: oxo-[ZrAminoAcid].Xy.nHO, wherein Zr is zirconium, X is an anion of a mineral acid, and n and y are numerical values from 0 to 20. A method of making an antiperspirant active zirconium-aluminum-amino acid compound comprising mixing an oxo-hexameric zirconium-octaamino acid salt with aluminum chlorohydrex and/or aluminum chloride, and drying the mixture. The smallest oxo-hexameric zirconium-octaamino acid salt of this invention provides stability, efficacy, and shelf life of zirconium-amino acid species for formulations in antiperspirant and/or deodorant compositions.
