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.

Antiperspirant suspensions containing finely divided aluminium and zirconium, having better effectiveness and a process for their manufacture

A process for synthesis of finely divided antiperspirant suspensions includes providing an antiperspirant salt consisting essentially of an Al salt which is effective as an antiperspirant and which is described by an empirical formula as follows: Al(OH)( X zH O where b&equals;0.4 to 3, z<4, and X&equals;halogen; mixing the Al salt into a non-aqueous oil phase to provide a mixture; and subsequently grinding the mixture with a suitable milling device at a temperature below 80&deg; C. to provide a suspension having a preselected fineness. A perspiration-inhibiting cosmetic preparation includes, as active ingredient, the antiperspirant suspension described above.
