HIGH EFFICACY, LOW RESIDUE ANTIPERSPIRANT STICK COMPOSITIONS

摘要

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.
