Beschreibung
Zusammenfassung:	An improved process for the preparation of aluminum/zirconium/glycine complexes, which is particularly suited to the production of novel ZAG salt complexes having enhanced antiperspirant efficacy, comprises forming an aqueous admixture of a zirconium starting material and glycine at ambient temperature; combining said zirconium/glycine aqueous mixture with an aluminum chlorohydrate starting material; and rapidly drying the resultant aluminum chlorohydrate/glycine/zirconium mixture. The aluminum/zirconium/glycine complexes produced thereby and antiperspirant compositions containing them are also disclosed.
