| abstract |
The present invention comprises about 0.5% to about 60% by weight of the particulate antiperspirant active agent, about 16% to about 50% by weight of the solid suspending agent, about 10% to about 80% by weight of the volatile silicone, and about 1% by weight of the nonvolatile silicone. Anhydrous sticky antiperspirant comprising from about 35% by weight to about 35% by weight, wherein the stick is substantially free of non-volatile organic liquids, preferably having a ClogP value of greater than 5.5, with a product hardness of at least about 600 Grams, and furthermore, the sticks are characterized by low persistence and / or high antiperspirant efficacy measures. Such compositions retain low retention and good antiperspirant efficacy, even though they contain a relatively high solid suspension concentration of at least 16% by weight. |
