Abstract:
An antiperspirant composition comprising:a) from about 5% to about 65% by weight of an antiperspirant from the group of activated and activated or unactivated antiperspirant compositions selected from; (I) those aluminum zirconium actives having the formula AlnZr(OH)(3n+4âˆ’x)Yx(AA)q(R)p 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; (II) those basic aluminum chlorides having the formula; Al2(OH)6âˆ’x1Yx1(R)p â€ƒwherein Y is Cl, Br, I and/or NO3 and xl 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; and (III) those aluminum and aluminum-zirconium salts combined with zinc and/or tin having refractive index of antiperspirant powder from 1.40 to 1.58 and preferably low surface area to mass ratio; and b) a non-aqueous phase consisting of at least three components selected from nonpolar, nonwater miscible organic liquid capable of providing stearic space, polyesters and polyethers from fatty acids and alcohols; alkoxylated fatty esters of PEG and silicone copolyols and alkoxylated methyl glucoside; and c) wherein the chosen nonaqueous phase has a refractive index from 1.40 to 1.50 and the average particle size of the antiperspirant is less than 3 microns and the viscosity of the wet milled antiperspirant is less than 50,000 cps.
