Patent ID: 7014843

Claim:
An aqueous antiperspirant active composition comprising admixing: (a) a basic aluminum halide having the empirical formula Al 2 (OH) 6-x1 Y x1 Rp(AA)q wherein Y is Cl, Br, or I and 1.3≦x 1 ≦1.7, wherein R is an organic solvent having at least two carbon atoms and at least one hydroxy group and p has a value of 0≦p≦1.0 and wherein (AA) is amino acid or amino acid compound and 0≦q≦0.5 and aluminum material being further characterized by: (i) size exclusion high performance liquid chromatography test band having a Band I relative area value of less than 5%, a Band II relative area value of 20% to 60%, Band III relative area value of 10% to 35% and Band IV relative area value of 15% to 50% and the sum of Band III and Band IV relative area value of at least 45% and no more than 70% and (ii) 27 Al NMR spectrum wherein at least 45% of the total area under the spectrum from +100 ppm to −100 ppm is contained in the sum of the areas of resonance lines at or below 10 ppm and (iii) in which the area of the resonance at 63 ppm is less than 0.1% of the total area under the spectrum from +100 ppm to −100 ppm and (iv) which comprises 30 to 42% by weight of anhydrous basic aluminum halide antiperspirant active in water and (b) at least one other antiperspirant active material which is selected from the group consisting of antiperspirant active of Zr salts, antiperspirant active of Hf salts, antiperspirant active of Ti salts and antiperspirant active of Sn salts.
