Abstract:
A skin friendly antiperspirant composition which comprises from about 70% to about 98% by weight of an antiperspirant active selected from those aluminum-zirconium-glycine salts having the formula:AlnZr(OH)(3n+4âˆ’x)Yx(AA)q(R)pâ€ƒâ€ƒ(I) wherein â€œnâ€  is from 2.0 to 10.0;wherein â€œxâ€  is from 1.4 to 12.3, calculated from metal to anion ratio of from 0.9:1 to 2.1:1; wherein â€œYâ€  is Cl, Br, I and/or NO3 wherein â€œqâ€  is from 0.5 to 3.0; AA is amino acid, and wherein â€œRâ€  is an organic solvent having at least two carbon atoms and at least one hydroxy group and â€œpâ€  has a value of from zero to 1.5; and those basic aluminum chlorides with the formula:Al2(OH)6âˆ’x1Yx1(R)pâ€ƒâ€ƒ(II) wherein Y is Cl, Br, I and/or NO3 and x1 is greater than zero and less than or equal to six (i.e., 01&lE;6); and wherein â€œRâ€  is an organic solvent having at least two carbon atoms and at least one hydroxy group and â€œpâ€  has a value of from zero to 1.5;(III) and those aluminum and aluminum-zirconium salts combined with zinc and/or tin and from about 2% to about 30% by weight of a polyhydric alcohol having at least three to about 12 carbon atoms and at least three hydroxy groups and wherein from about 2% to about 70% of the polyhydric alcohol is complexed with the metal or metals present in the antiperspirant salts.
