Disclosed are aqueous antiperspirant active compositions comprising admixtures of basic aluminum halides and metal cation salt yielding enhanced antiperspirant efficacy; and methods of making such compositions. The basic aluminum halides, optionally contain an amino acid or salts of amino acids, and/or antimicrobial agent and are combined with a metal cation antiperspirant and, optionally, with a organic solvent having at least two carbon atoms and at least one hydroxy group and mixtures thereof. The basic aluminum halide of this invention has a Size Exclusion Chromatography (HPLC) Test Band I of less than 5%, preferably less than 1%, Band II percent aluminum value of 20%-60%, preferably about 35%-55%, Band III percent aluminum value of 10%-35%, preferably 15%-30%, and Band IV value of 15%-50%, preferably 25%-35%, and sum of peak 3 and 4 areas of at least 45% and no more than 70%, preferably 65%. |
