The invention concerns the use as an antiperspirant active compound of a basic aluminium chloride, bromide or iodide having an aluminium to chloride, bromide or iodide molar ratio of from 0.5 to 2.5:1 in the form of a powder or an aqueous solution having an aluminum concentration of at least 2.5% by weight, the basic aluminium compound exhibiting on analysis by a size exclusion chromatographic method a fraction (referred to as the Band III fraction) having a relative retention time within the range of 0.76 to 0.82 in which fraction there is contained at least 20% of the aluminium. The compound has less than 20% of the total aluminium contained in polymers having a size greater than 100 Angstroms. |
