Abstract
Aluminum chlorohydrate salts having an amount of Peak 1 material relative based on a total of Peaks 3, 4, and 5 of at least 20% as measured by size exclusion chromatography, together with water treatment compositions, antiperspirant compositions, and oral care compositions, comprising the same, and methods for making and using the same.
Claims13
An aluminum chlorohydrate salt composition having an area of Peak 1 material relative to the sum of the areas of Peaks 3, 4, and 5 of at least 20%, as measured by size exclusion chromatography, wherein the composition further comprises arginine, and the molar ratio of arginine:aluminum is 2.25:1 to 3:1.
A method of making a salt, comprising heating an initial aluminum salt solution at a temperature of about 50°C., in the presence of arginine, until the area of Peak 1 material relative to the sum of the areas of Peaks 3, 4, and 5 is at least 20% as measured by size exclusion chromatography, wherein the aluminum salt is at least one of aluminum chloride, aluminum chlorohydrate, aluminum dichlorohydrate, aluminum sesquichlorohydrate, aluminum zirconium octachlorohydrate, aluminum zirconium pentachlorohydrate, aluminum zirconium tetrachlorohydrate, or aluminum zirconium trichlorohydrate, and wherein the molar ratio of arginine:aluminum is 2.25:1 to 3:1.
