摘要： An improved process for preparing an enhanced antiperspirant active polymeric aluminum compound having the empirical formula:Al.sub.2 (OH).sub.6-a X.sub.a (I)wherein X is Cl, Br, F, I, SO.sub.4 and NO.sub.2, a is about 1.0 to about 4, which is further characterized by (a) a Size Exclusion Chromatograph, (b) a Band III percent aluminum value of at least 40 percent, and preferably (c) a Band I percent aluminum value of not greater than 5 percent, and compositions thereof.
