Abstract
An antiperspirant suspension which is finely divided, which is contained in a non-aqueous phase, and which has improved efficacy for perspiration reduction when used on human skin, includes at least one basic aluminum-zirconium-halogenohydrate complex as active ingredient in which at least 60% of the zirconium content can be directly titrated after dissolving in 0.1 n HCl with EDTA at a pH of 0.8, wherein the active ingredient optionally contains an amino acid. A process for the synthesis of the antiperspirant suspension includes mixing an aluminum salt which is effective as an antiperspirant with a zirconium salt which is effective as an antiperspirant, optionally in the presence of an amino acid, in a non-aqueous oil phase in the absence of water to provide a mixture; and grinding the mixture.
