Patent ID: 10632052

Abstract:
An aqueous composition comprising basic aluminium chloride salt of formula Al2(OH)4.4Cl1.6 to Al2(OH)4.9Cl1.1, calcium chloride at a molar level of 0.020 or greater relative to the aluminium present, and glycine at a molar level of 0.050 or greater relative to the aluminium present, characterised in that the molar ratio of aluminium to the sum of the molar amounts of the calcium chloride and glycine is from 3.9:1 to 6.1:1 and in that the molar ratio of glycine to Al is greater than 1.7:10 and the molar ratio of Ca to Al is less than 0.35:10 or the molar ratio of Ca to Al is greater than 0.35:10 and the molar ratio of glycine to Al is less than 1.7:10.
