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.

A novel aluminum magnesium hydroxy fatty acid compound is disclosed having a general formula, Al.sub.x Mg.sub.y (OH).sub.3x+2y-z R.sub.z.nH.sub.2 O, wherein R is at least one aliphatic monocarboxylic acid group having the formula RCOO.sup.- and comprising from 12 to 22 carbon atoms, and wherein x=2, 2.ltoreq.y.ltoreq.10, z=2, and n is an integer greater than zero. The compound is prepared by a process including placing water and a salt which is one of an alkali metal salt or an ammonium salt of at least one aliphatic monocarboxylic acid having from 12 to 22 carbon atoms in a reactor fitted with heating and stirring means. The salt is dissolved by intensive stirring and by heating to a temperature ranging from 20.degree. to 90.degree. C. to provide a salt solution. The pH of the salt solution in the reactor is maintained at a pH of at least 8 to provide an alkaline solution. A solution comprised of water, an aluminum salt, and a magnesium salt is added to the reactor under constant stirring to cause reaction and precipitation of a precipitate comprised of the novel aluminum magnesium hydroxy fatty acid compound. The precipitate is separated and washed with substantially demineralized water until substantially no anions of the aluminum salt and the magnesium salt are detectable. A lipogel with improved thermal stability is formed using the novel compound and organic lipophilic compounds which are liquid at room temperature, and is useful in cosmetic or pharmaceutical preparations.
