Abstract
Disclosed are anhydrous antiperspirant sticks that comprise from about 0.5% to about 60% by weight of particulate antiperspirant active; from about 16% to about 50% by weight of a solid suspending agent; from about 10% to about 80% by weight of a volatile silicone; and from about 1% to about 35% by weight of a non volatile silicone, wherein the sticks are preferably substantially free of nonvolatile organic liquids having a C log P value greater than 5.5, and have a product hardness of at least about 600 gram·force. The sticks are further characterized by defined low residue and/or high antiperspirant efficacy measures. These compositions contain relatively high solid suspending agent concentrations of at least 16% by weight and still provide low residue performance and high antiperspirant efficacy.
