Abstract
Abstract Antipersipirant cream compositions, comprising: (a) from about 5% to about 60% of a volatile silicone oil (b) from about 5% to about 60% of a non-volatile emollient having a viscosity of at least about 2 cs at 25 DEG C.; (c) from about 2% to about 10% of a particulate thickening material; and (d) from about 15% to about 45% of a particulate antiperspirant active material; wherein the compositions have penetration force values of from about 250 grams to about 800 grams. These compositions preferably contain a cosmetic powder material, at a level of from about 0.5% to about 20%. This invention also provides methods for making these compositions.
