Abstract:
A composition comprising a polyhydroxyoxoaluminum cation detectable at 76 ppm by 27 Al NMR that is present in a relative abundance on a 27 Al NMR spectrograph that is greater than any other polyhydroxyoxoaluminum cation detectable by 27 Al NMR. Also, disclosed are methods of making the composition.
Abstract:
A composition comprising an aluminum chlorohydrate salt, the aluminum chlorohydrate salt having at least 50 mole % Al 30 polyhydroxyoxoaluminum cation of all polyhydroxyoxoaluminum cations detectable by quantitative 27 Al NMR within the aluminum chlorohydrate salt, and a buffer. The composition can optionally include zirconium. Also disclosed are a method of making an aluminum salt using an increased molar concentration of a starting aluminum salt with a buffer, a method of reducing perspiration with the aluminum chlorohydrate salt, and a method of treating water with the aluminum chlorohydrate salt.

Abstract:
A method of making aluminum salt compositions using a combination of a basic organic buffer with a source of alkaline earth metal ions. This selection of basic organic buffer provides for a lower alkaline earth metal salt content in the composition made by the method.
Abstract:
An antiperspirant active composition comprising an aluminum salt, the aluminum salt (i) having an aluminum to chloride molar ratio of 0.3:1 to 3:1; and (ii) having a species of polyhydroxyoxoaluminum cation detectable at 76 ppm by 27 Al NMR that is present in a relative abundance on a 27 Al NMR spectrograph that is greater than any other polyhydroxyoxoaluminum cation detectable by 27 Al NMR. Also, disclosed are methods of making the antiperspirant active.

Abstract:
An antiperspirant active composition comprising an aluminum salt, the aluminum salt (i) having an aluminum to chloride molar ratio of 0.3:1 to 3:1; and (ii) exhibiting an 27Al NMR spectrum with a species distribution including at least 90% A130 polyhydroxyoxoaluminum cation as the predominant species detectable by 27Al NMR within the aluminum salt. The composition can optionally include zirconium. Also disclosed are a method of making an antiperspirant active composition and the use of a heating step at elevated temperature to convert Al13 polyhydroxyoxoaluminum cations in the species detectable by 27Al NMR within an aqueous aluminum salt solution into Al30 polyhydroxyoxoaluminum cations in the species detectable by 27Al NMR without increasing a SEC Peak 3 area in the SEC chromatogram of the aluminum salt.
