    • Disclosed is a basic aluminum material having enhanced antiperspirant activity, the material having the empirical formula Al₂(OH) 6-a X a , where 0.5 ≦ a ≦ 5.0, and X is a univalent complex oxoanion of nitrogen, chlorine and other halogens, which forms salts with Al³⁺ in aqueous solution so that these salts are essentially completely dissociated, which is readily soluble in water with metallic ions in the solution, and which forms conjugate acids that are strong acids; and wherein the material is characterized by:
      (a) size exclusion high performance liquid chromatography peaks corresponding to peak 3 and peak 4 of size exclusion chromatograms formed by HPLC technique; (b) a peak 4 relative area of at least 25%, a peak 3 relative area of less than 60%, the sum of the relative peak 3 and peak 4 areas being at least 50%; and (c) less than 10% chromatographic peaks eluting at shorter retention times than peak 3, corresponding to peaks 1 and 2. Illustratively, the univalent oxoanion can be ClO₃⁻, ClO₄⁻, IO₄⁻, and preferably NO₃⁻. The material is characterized by having et least 25% by weight thereof in the form of Al b polyhydroxyaquoaluminum species. Also disclosed are antiperspirant compositions including the basic aluminum material, a zirconium, hafnium, titanium and/or tin antiperspirant active material and a neutral amino acid, and methods of forming the basic aluminum material and the antiperspirant composition. The basic aluminum material can be formed at relatively low temperatures, without first forming a dilute solution of a basic aluminum compound, and the basic aluminum material has a stable enhanced activity in aqueous solution over a relatively long period of time.

    • Process for the preparation of a sodium paraperiodate wherein an iodine compound is converted into the sodium paraperiodate in the presence of Na.sup.+ ions by means of an alkali metal hydroxide and an alkali metal hypochlorite. The iodine compound is applied in the form of an iodine-containing mixture in which besides the iodine compound in the form of I.sub.2, iodide or iodate compounds, one or more compounds chosen from the group of chlorides, bromides, sulphates, sulphites, carbonates, bicarbonates, nitrates and dissolved organic components are also present. The invention also relates to the preparation of sodium metaperiodate and other alkali and alkali earth metal periodates, wherein the sodium paraperiodate obtained is converted into sodium periodate or into an alkali or alkali earth metal periodate by means of an acid or an alkali and alkali earth metal salt at an elevated temperature. The acid used preferably is HNO.sub.3.

    • Disclosed are basic aluminum antiperspirant materials having univalent complex oxoanions (e.g., nitrate); methods of making such materials; antiperspirant compositions containing such basic aluminum materials, another antiperspirant active material (e.g., a basic zirconium halide salt), and optionally a neutral amino acid; and methods of making such compositions. Size exclusion high performance liquid chromatography chromatograms of the disclosed basic aluminum materials have a peak 4 relative area of at least 25%, a peak 3 relative area of less than 60%, the sum of the peaks 3 and 4 being at least 50%; and less than 10% of the chromatographic peaks eluting at peaks 1 and 2. The disclosed basic aluminum materials have less than 25% of the aluminum in the form of Al.sup.b polyhydroxyaquoaluminum, and have a .sup.27 Al NMR spectrum in which the area of the 71.5-73.5 ppm resonance line includes more than 50% of the combined areas of the 62.5-63.5 ppm and 71.5-73.5 ppm resonance lines, and 5%-30% of the total area under the spectrum from 140 ppm to -80 ppm is contained in the resonance line at 71.5-73.5 ppm. The basic aluminum material of the present invention can be produced by adding a stoichiometric or near-stoichiometric amount of aluminum metal to a solution of an aluminum salt having a univalent complex oxoanion; the basic aluminum material can also be made by adding to such solution of the aluminum salt, aluminum metal having, in total, a relatively small surface area (large-sized particles of aluminum).
