Abstract
Abstract Antiperspirant 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 liquid C 12 -C 25 saturated or unsaturated hydrocarbon emollient; (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 150 grams to about 800 grams at 25° C. and at 50% relative humidity. 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.
