Abstract
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=0.4 to 3, z<4, and X=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° C. to provide a suspension having a preselected fineness. A perspiration-inhibiting cosmetic preparation includes, as active ingredient, the antiperspirant suspension described above.
