    Abstract: A composition comprising an aluminum chlorohydrate salt, the aluminum chlorohydrate salt having at least 50 mole % Al30 polyhydroxyoxoaluminum cation of all polyhydroxyoxoaluminum cations detectable by quantitative 27Al 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.
